But this time, I am returning to a theme that I have harped on before--the fact that nothing is really "free"; every energy source, every material, every structure in our highly industrialized environment comes with pluses...and minuses. I had thought I had beaten this theme to death, but in recent weeks, discovered 2 new examples--at least they are new to me--that I think bear mentioning. </p><p> </p><p>The first example I came across was a discussion of the <a href="https://www.terradaily.com/reports/US_cracks_down_on_potent_class_of_greenhouse_gases_999.html" target="_blank">environmental impacts of hydorfluorocarbons (HFCs)</a>. HFCs are commonly used in refrigerators and air conditioners. The article ominously notes that HFCs can be
hundreds to thousands of times more potent than carbon dioxide at
trapping heat in the atmosphere, exacerbating the climate crisis. In fact, they call them "super-pollutants." But the point that really got my attention was the last sentence of the article, which stated that HFCs were first introduced in the 1990s, before their powerful
heat-trapping properties were understood, to replace chlorofluorocarbons
(CFCs) that had been found to erode the ozone layer.</p><p> </p><p>To me, then, in addition to the argument made in the article that there is a need to find a replacement for HFCs, the article drives home the point that everything we do has some impact, and that we need to be more aware of this. After all, this is not be the first time that we thought that advances in technology were enabling us to replace something polluting or damaging with something better, only to find that the "better" technology came with its own shortcomings. The classic example is that everyone thought automobiles would replace the "pollution" from horses on city streets, only to find that automobiles generated a different kind of pollution.</p><p> </p><p>The other example I recently learned about deals with some of the <a href="https://time.com/6218869/why-atlantic-hurricanes-are-getting-stronger/?utm_medium=email&utm_source=sfmc&utm_campaign=newsletter+brief+default+ac&utm_content=+++20221003+++body&et_rid=207494026&lctg=207494026" target="_blank">possible causes of the increased strength of hurricanes</a>. Most of the discussion I had heard to date related to the emissions of greenhouse gases (GHGs). However, this article cites another cause <u>in addition to GHGs</u>--the Atlantic has also experienced a reduction in aerosol pollution. Some of that may be due to a reduction of Saharan dust in the last few decades, since hotter sea surface temperatures are weakening trade winds from
Africa that transport the dust. <u>But some of it is due to a reduction in
sulfate pollution from industry following the passage of the Clean Air Act in the
1970s</u>. From this article, it is not clear how much of the effect is due to the reduction in sulfate pollution, but the fact that it has this impact suggests that, once again, something we did with the intention of fixing one problem might be making another problem worse.<br /></p><p><br /></p><p>I would like to think that we have gotten smart enough to realize this and to be able to analyze systems to figure out their potential negative impacts before we unleash them on the world. Or to phase in new technologies to assess their impacts before we have totally committed to them. Perhaps that is not realistic. But we should certainly try to anticipate "unexpected" impacts as much as possible, and we should monitor the impact of changes--whether introduced by laws to replace one process or material with another, or simply by the introduction of new technologies--so we can catch the impacts sooner and make necessary adjustments.</p><p> </p><p>I am particularly interested in this issue because, for years, I have seen solar and wind power compared to nuclear power. Without getting into an in-depth discussion here of all the issues, the general impression is that solar and wind are "natural" and therefore, are clean, while nuclear is not. These arguments ignore the fact that solar and wind power require a lot of materials, some of them exotic, and that these materials need to be mined, manufactured, and disposed of. And these sources are intermittent, so some form of storage or backup power is needed. This doesn't mean that we should abandon solar or wind power. Far from it. But we need to incorporate it into our electricity supply systems with a full understanding of what is needed to make it work, and of all the impacts, and we need to balance these against nuclear power and other energy sources. <br /></p><p> </p><p>I am not trying to say that we can never introduce new technologies just because they may have negative impacts.
I am just issuing a reminder that everything has impacts, positive and
negative. We do need to be more proactive in figuring out those impacts and in addressing them as early as possible. And we need to try to move away from the mindset that one technology is "good" and another is "bad," and look instead for balance between alternative technologies to meet our needs while minimizing negative impacts. <br /></p><p><br /></p><p>***<br /></p><p> </p><p></p><p><br /></p><p><br /></p><p> </p><p> </p><p><br /></p><p><br /></p><br />Gail Marcushttp://www.blogger.com/profile/03389387408479728702noreply@blogger.com0tag:blogger.com,1999:blog-8740971876602952565.post-56729103118033774252022-01-05T10:47:00.002-08:002022-01-05T13:08:29.789-08:00EU to Propose Considering Nuclear Power--but not on a Level Playing Field<p>It has been a long time since I was moved to write a blog, perhaps because I feel that I have already addressed many of the major issues, and I do not like to just repeat myself. However, the recent reports that the <a href="https://www.reuters.com/markets/commodities/eu-drafts-plan-label-gas-nuclear-investments-green-2022-01-01/">European Union (EU) is considering allowing nuclear power and natural gas to be added to the list of "green technologies</a>," but with "conditions," has me disturbed enough to break my silence.</p><p> </p><p>As the Reuters article notes, the EU is responding to pressure from a number of countries to consider nuclear power and natural gas in its taxonomy of "green technologies," but it is trying to address the opposing pressures of the anti-nuclear countries by imposing conditions that appear to be tailor-made to make it extremely difficult for a country to comply. Specifically, "the project has [to have] a plan, funds and a site to safely dispose of radioactive waste." Since we know that disposal of radioactive waste has been a political football in many countries for years, it doesn't take much imagination to figure out what is likely to happen. Or not happen. <br /></p><p> </p><p>I can't object to requiring a technology to consider the full life-cycle impacts. BUT...if nuclear power is required to do this, why not wind energy and solar energy? While the wind and the sun may be free and clean, we can't get usable amounts of energy from them without creating a lot of other impacts. Numerous <a href="https://www.theverge.com/22858437/2021-mining-critical-minerals-clean-energy-renewables-climate-change">reports have documented the rare materials needed, and the wastes generated, by wind and solar energy</a>. In fact, given the low density of these energy sources, the amount of materials that are required to build the structures and systems to capture these distributed energy sources is huge. These materials need to be mined and fabricated to build windmills or solar panels, and disposed of at the end of the lives of the windmills and solar power plants. Some of the materials used may be scarce and are currently available largely from places like China, which we do not want to depend on for basic energy needs, and many are potentially hazardous to human health and to the environment. </p><p> </p><p>There are some requirements for natural gas plants as well. They must replace something more polluting, which is a good thing. And there are emission standards--at the power plant itself--that assure that more advanced natural gas technologies are used. However, once again, they don't take the full life cycle into consideration. Specifically, they don't include consideration of methane emissions at the point of extraction, and methane is a potent greenhouse gas. And for natural gas, too, there is a supply issue. With Russia being a major supplier of natural gas to some European countries, we have already seen that it can easily be used for political advantage. <br /></p><p> </p><p>If anyone who has followed my blog thinks that <a href="http://nukepowertalk.blogspot.com/2021/02/renewable-energy-and-waste.html">I have mentioned all of this before</a>, indeed I have. I probably wouldn't have addressed the issue again, except for the fact that the EU is about to go down a bizarre and counterproductive path. Don't get me wrong. I think it is fine if the EU wishes to consider the whole life cycle of energy sources. And it's a good idea to require some plan to assure that there will be financing for end-of-life requirements. In fact, these conditions are probably appropriate. I just think that it is important for <b>all</b> energy sources to be treated equally, and that these same conditions are applicable for addressing the materials needs for wind and solar systems. That would be the best outcome for the people of the EU and for their environment. </p><p> </p><p>But going forward with a plan that imposes requirements on one technology and not on another strikes me as the worst of all worlds. The people of Europe are likely to be saddled with an energy mix that they believe is "clean" and "renewable," but that will turn out to be unreliable, costly, and that, in the end, will leave future generations with a huge quantity of highly hazardous waste. And probably with nowhere to dispose of it. </p><p><br /></p><p>***<br /></p><p> </p>Gail Marcushttp://www.blogger.com/profile/03389387408479728702noreply@blogger.com0tag:blogger.com,1999:blog-8740971876602952565.post-25218309762140458192021-05-04T17:13:00.004-07:002021-05-04T17:15:33.200-07:00In Memoriam: Peter Lyons<p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-hykKgVaLLL8/YJG7FB2PvFI/AAAAAAAAA-g/KHSbz5xyDLYg-juZc0I0sC_bjg0MtN8aACLcBGAsYHQ/s275/220px-Dr._Peter_B._Lyons.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="275" data-original-width="220" height="247" src="https://1.bp.blogspot.com/-hykKgVaLLL8/YJG7FB2PvFI/AAAAAAAAA-g/KHSbz5xyDLYg-juZc0I0sC_bjg0MtN8aACLcBGAsYHQ/w197-h247/220px-Dr._Peter_B._Lyons.jpg" width="197" /></a></div><br />I was very sad to learn that Peter B. Lyons passed away on April 29. He began his long and distinguished career at the Los Alamos National Laboratory, and then spent many years in Washington, first as a Science Advisor to U.S. Senator Pete Domenici and the
Senate Committee on Energy and Natural Resources, and later, as a Commissioner at the Nuclear Regulatory Commission (NRC), and finally as the Assistant Secretary for Nuclear Energy at the Department of Energy (DOE). During the course of his career, he made numerous contributions to nuclear science and nuclear policy, some of which are described in <a href="https://www.energy.gov/contributors/peter-b-lyons">the DOE's bio on Pete</a> and in the <a href="https://www.ans.org/news/article-2861/the-nuclear-community-remembers-peter-lyons/">American Nuclear Society's (ANS) newswire article</a> on his passing. <p></p><p> </p><p>In addition to being a person of so many accomplishments, he was also an extraordinary human being, and I would like to focus on some of his personal characteristics that I observed in my many interactions with him over the years. </p><p> </p><p>I first got to know Pete Lyons well when I was the Principal Deputy Director of the Office of Nuclear Energy in DOE. He was one of the Capitol Hill staffers I met with periodically to discuss the work of my office. Although Hill staffers are notoriously busy and overworked, and in other offices, I was often kept waiting or given only a brief, rushed audience, Pete was invariably respectful of the time of anyone visiting his office, and very thoughtful and knowledgeable in discussions. His focus was always on the science and on the national good. <br /></p><p> </p><p>When I left DOE, I continued to see him occasionally at various conferences and other events, and to follow his career. I have a special memory from 2013, when I served as the Faculty Member in Residence (FMR) for the Washington Internships for Students of Engineering (WISE), a program supported by the ANS and several other engineering societies to bring students to Washington for a summer to expose them to technology policy. One part of the program was for the FMR to arrange for the students to meet leaders working in the science and technology policy area from the government and other organizations. </p><p> </p><p>Pete was the Assistant Secretary for Nuclear Energy at that time, and I had arranged for the students to come as a group to meet him. While I have been impressed by the fact that many very high level, very busy people, such as NRC Commissioners, Assistant Secretaries, and others, do make time to meet with the WISE students, Pete did much more than give them a briefing. I had the students briefly introduce themselves and the topics they were studying that summer, and instead of just nodding his head and waiting for the introductions to finish, he engaged each of the students, asking them questions about their projects and offering them suggestions, or commenting on the schools or on other things they had mentioned. I even saw him taking notes on their names, schools, and professional societies. That showed a level of interest and engagement that went well above and beyond the norm.</p><p> </p><p>After Pete retired from DOE, he remained engaged professionally. I was delighted to see him be recognized last year with ANS’s Dwight D. Eisenhower Award for his influential leadership in nuclear
technology policy and for the vital role he played in the nuclear
renaissance of the early 21st century. And I was pleased to see an article authored by him in the February issue of <i>Nuclear News. </i>After I read that article, I sent him a message about it. In his typical fashion, he responded promptly and graciously, even though I was aware that he was very ill.</p><p> </p><p>In one of our last conversations in person, I noted to Pete that he and I both had served in NRC, DOE, and on the Hill--although I hasten to say that he served in a higher position than I did in each of these organizations! There are probably relatively few people with such backgrounds, and maybe it is one bond we shared. But my observation was that he treated everyone with courtesy and respect. </p><p><br /></p><p>He will truly be missed, not only for his many contributions to nuclear policy in his various positions, but for his outstanding personal characteristics as well. <br /></p><p><br /></p><p>***<br /></p><p> </p><p> </p><p><br /></p><p><br /></p>Gail Marcushttp://www.blogger.com/profile/03389387408479728702noreply@blogger.com0tag:blogger.com,1999:blog-8740971876602952565.post-43180870620361059462021-02-26T08:35:00.000-08:002021-02-26T08:35:44.314-08:00Clean Air and New Jobs: A Breath of Fresh Air<p>One of the more contentious challenges in the ongoing effort to move to a cleaner mix of fuels to run our modern world has been addressing concerns about the jobs that are lost, and the people who are affected, as we transition from the current mix of energy sources to a more advanced mix. </p><p> </p><p>And truly, that is a serious problem. We can look at the world and say that we made such transitions before--from horse-drawn carriages to automobiles; from burning wood to burning coal and then oil; etc. Those transitions, too, changed the mix and location of jobs. But most of those transitions occurred over longer periods of time than we are now envisioning, allowing people more time to adjust.</p><p><br /></p><p>Therefore, I was very pleased to hear <a href="https://apnews.com/article/joe-biden-technology-biden-cabinet-michigan-jennifer-granholm-15acadc1a86559e3a8a7e1d026a0732f" target="_blank">former Michigan Governor Jennifer Granholm's responses to questions in her Senate hearing</a> for the position of Secretary of the Department of Energy about the job implications of efforts to move to cleaner energy sources: </p><p> </p><p style="margin-left: 40px; text-align: left;">“We can buy electric car batteries from Asia, or we can make them in
America,” Granholm told senators. “We can install wind turbines from
Denmark, or we can make them in America.″</p><p style="margin-left: 40px; text-align: left;"> </p><p style="text-align: left;">One can argue that these are easy statements to make and harder measures to implement. And they may certainly mean that some people will have to move. But, it is also true that many of the jobs in the nuclear and renewable energy industries are good, high-paying jobs, and if measures like training and other support can be offered to those affected by closures of old facilities, then we potentially have a win-win. In addition, if jobs are made an important part of the plan to transition to cleaner energy, then efforts can be made to locate some of the manufacturing centers for the new products needed in the very places where mining and other jobs are being lost. </p><p style="text-align: left;"> </p><p style="text-align: left;">There are still many challenges ahead. It is easy to say that we will build the factories here, but it is harder to compete against the cheap labor in some parts of the world. It is easy to say that factories will be built in mining communities, but those decisions are not directly in the hands of the government. And this is not a short-term issue; we will need sustained attention to the impacts on jobs. <br /></p><p style="text-align: left;"><br /></p><p style="text-align: left;">However, if the recognition of need for job creation is made an integral element of the planning process, then a balanced approach to the energy transition can developed, one that considers the people as well as the environment. It will not be easy, and there will not be perfect solutions, but Secretary Granholm's statements at the Senate hearing are a very encouraging sign that we will plan in a holistic way that addresses both the needs of the overall population and the needs of the individuals most affected by the changes.<br /></p><p style="text-align: left;"> </p><p style="text-align: left;">***</p><p style="text-align: left;"> <br /></p>Gail Marcushttp://www.blogger.com/profile/03389387408479728702noreply@blogger.com0tag:blogger.com,1999:blog-8740971876602952565.post-49793312896076270462021-02-07T09:58:00.000-08:002021-02-07T09:58:15.343-08:00Renewable Energy and Waste<p>I was delighted to see a news item recently in the American Nuclear Society Nuclear Cafe reporting on an article discussing the <a href="https://www.ans.org/news/article-2599/renewable-technologies-cant-escape-the-issue-of-waste-management/">waste generated by renewable energy systems</a>. Of course, I'm not delighted because there is waste from renewable energy systems! Rather, I am delighted that the problem is beginning to be recognized. This is a topic that I've addressed several times in <a href="https://nukepowertalk.blogspot.com/2019/03/environmental-impacts-of-renewables.html">past blogs</a>, but I've always felt that the issue wasn't getting the attention that is needed, and that my voice was a lonely voice in the wilderness. </p><p><br /></p><p>Unfortunately, the terminology that has developed around energy sources has led to a widespread belief that renewable energy sources are "clean" because they generate no emissions when they produce energy. Lost in the discussion is the fact that the production of energy is only one step in the lifecycle of any energy producing system. All energy sources require materials that need to be mined and processed, and some of the materials traditionally used for solar and wind plants may be toxic. And all power producing plants ultimately reach the ends of their lifetimes, which means that all the materials used in the construction and operation of those power plants ultimately need to be disposed of as well. </p><p><br /></p><p>The ANS article and my previous blog detail some of the specific wastes produced by solar and wind power plants, so I will not repeat that discussion here. The only point I would add to the discussion in that article is one of volume. It is often overlooked that the distributed nature of wind and solar energy means that the systems used to extract that energy for human use have to be large and have to use a lot of materials. Getting our energy supply from the wind and the sun requires thousands and thousands of wind turbines and solar panels. Therefore, the issue is that, not only are there hazardous wastes created when we build wind and solar power plants, the volume of that waste is very large. By contrast, the amount of waste generated by a nuclear power plant is much smaller. And both radioactive wastes from nuclear power plants and hazardous wastes from other power sources may need to be sequestered for long periods of time. <br /></p><p><br /></p><p>The important point is to recognize that no energy source is completely "clean." Every source of energy generates some form of waste somewhere in the lifecycle of the system. It is also true that we can expect to find solutions for dealing with most of these wastes. Some of these solutions are in early stages of development, and we may need a lot more work to assure that they will be effective. And all of them will add to the costs of energy production. And, yes, all of them are likely to generate needs for places to dispose of toxic materials sometime in the future. The point is that these aspects of our energy supply need to be better recognized by everyone involved--the technical community developing these systems, the energy companies seeking to build them, the communities wishing to host them, and the general public.</p><p><br /></p><p>Hopefully, this article will start a broader dialogue on this important issue.</p><p> <br /></p><p>*** <br /></p>Gail Marcushttp://www.blogger.com/profile/03389387408479728702noreply@blogger.com0tag:blogger.com,1999:blog-8740971876602952565.post-45873300354321156202021-01-12T11:49:00.000-08:002021-01-12T11:49:37.180-08:00Fiestaware: Understanding Radiation <p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://www.orau.org/ptp/collection/consumer%20products/fiestback.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="264" data-original-width="300" height="176" src="https://www.orau.org/ptp/collection/consumer%20products/fiestback.jpg" width="200" /></a></div><br />Almost 10 years ago, I wrote a <a href="https://nukepowertalk.blogspot.com/2011/09/uranium.html?m=0#comment-form">blog on Fiestaware</a> when I noticed that the Post Office had issued a stamp honoring the man who had designed the original Fiestaware line (Frederick Hurten Rhead). My tone was a bit lighthearted, as one color of classical Fiestaware was made with a uranium glaze that gave it a distinctive orange color, so it had become something I personally enjoy collecting and using. (Well, collection may be a bit exaggerated, but I do have a couple of pieces, and I also have a couple of pieces of Vaseline glass, a product that similarly used uranium to color glass. And for any other would-be collectors, I do want to note that the Fiestaware that is in production today doesn't use that glaze. You have to look in antique shops.)<p></p><p> </p><p>I did not think I would ever have a reason to revisit this subject, but yesterday's news featured an article about a <a href="https://www.nj.com/camden/2021/01/nj-teens-science-project-forces-evacuation-of-high-school.html">school at which a hazmat emergency was declared</a> because a student brought in a small sample of uranium-containing classical Fiestaware! The first thing that has me scratching my head is that the student brought it in because they were demonstrating the use of a Geiger counter. A Geiger counter needs a little radiation to show it's stuff! Duh! The second thing that struck me about this story is the profound ignorance that still surrounds anything with the "r word"--radiation. </p><p> </p><p> People seem to be able to put other risks in perspective, but whether because of history, because it is invisible, or for any one of a number of other reasons I have heard, people do not seem to be able to understand even the basics of radiation. This clearly is one factor that has dogged the nuclear power industry for its entire existence.</p><p> </p><p> I wish I had a magic answer to this dilemma, a way to educate people and to make them understand what they should fear and what they do not need to fear. But it is clear that, as we continue to try to educate the public on the safety of nuclear power plants, we need to keep in mind that we should be sure the educational tools cover things more basic than the nuclear power plants, in particular, the radiation from not only the nuclear plants, but from even such innocuous items as an antique orange plate.<br /></p><p> <br /></p><p>***</p>Gail Marcushttp://www.blogger.com/profile/03389387408479728702noreply@blogger.com6tag:blogger.com,1999:blog-8740971876602952565.post-11853248758243683592020-12-16T14:01:00.000-08:002020-12-16T14:01:25.231-08:00Jill Biden's Title<p>I was as appalled as most people when I heard the news the other day about <a href="https://www.wsj.com/articles/is-there-a-doctor-in-the-white-house-not-if-you-need-an-m-d-11607727380">Joseph Epstein's opinion piece</a> in the Wall Street Journal advising Jill Biden that she should not insist on being addressed as "Doctor." Aside from the obvious fallacy of his argument--that a Ph.D. is not a <i>real</i> doctor--and aside from the clear sexism, it was a sad reminder of how slowly things change.</p><p> </p><p>As a woman who holds an earned doctorate in engineering, I have had my share of experiences with people addressing me incorrectly. In one memorable incident early in my career, a colleague and I were meeting with a client. The client addressed me as Mrs. Marcus, but called my colleague Dr. Bxxx.

former classmates, we can share stories of such slights for hours on

<span style="font-size: x-large;"><span style="color: purple;"><b>A Reminder of What's Important</b></span></span></div>
<br />
As we get used to the "new normal" of living with the specter of the novel coronavirus looming over us, we are being reminded of all the things it takes to maintain our lives and well-being.<br />
<br />
Some of these are obvious, and are the kinds of people that we've always known were essential. Doctors. Nurses. EMTs. And everyone else in the medical field staffing the hospitals and emergency rooms, and administering life-saving procedures. Police. Firefighters. Military personnel. All those who are always on the front lines when there are emergencies in our cities and towns. <br />
<br />
Others are visible, but are people we never used to think about when the word "emergency" was uttered. People who stock shelves and operate cash registers at pharmacies and grocery stores. Kitchen staff at restaurants serving our new take-out-only world. Gas station attendants. Delivery personnel. People who clean the grocery stores, pharmacies, and other establishments that are still open. People who collect our trash. People who repair our infrastructure. People who gather and report the news. <br />
<br />
Many others are working behind the scenes. We never see them, but our dependence on them has become more and more obvious as we have moved into crisis mode. The farmers and distributors who grow, process, and ship our food. The factory workers employed at factories being retooled to provide the ventilators and masks needed in this health crisis. And yes, the toilet paper and hand sanitizer. The truck drivers who deliver the food and goods we need. The people who answer the phones of the services we call. The government workers who continue to assure that essential services continue to be supplied to the American public, and that health and safety oversight is maintained.<br />
<br />
And, last but not least, the people who assure that our power plants keep working, and that the power we so desperately need, especially during these difficult times, continues to be available. Power to run our hospitals. Power to run our factories. Power to keep our homes well lit and at a comfortable temperature. Power that enables us to operate all the technology that is helping us continue our work, keep in touch with each other, get needed medical advice, and so much more.<br />
<br />
Our power, of course, comes from a variety of sources, all of them needed, but in times like this, our nuclear plants are especially valuable, as they can operate for long periods of time without refueling. We should keep in mind that, at some sites, keeping the staff safe and available to provide the nation with much-needed power means that some staff are living on site, away from their loved ones. <br />
<br />
Right now, it is difficult for anyone to see what the world will look like when the COVID-19 crisis ends. Much will return to the old "normal," I'm sure. There will also be some changes. Unfortunately, some establishments that are shuttered may never reopen. Maybe more people will continue to work from home. There is much speculation, and only time will tell. But I hope that, even when things are back to normal, we remember the services that kept the wheels going during the current crisis--the people, the network of services, the factories, and the power plants. They are the hidden, but critical, elements that keep our society functioning. <br />

<div class="separator" style="clear: both; text-align: center;">
<a href="https://1.bp.blogspot.com/-J0ON5x5axvI/XotF-sNQflI/AAAAAAAAA5U/N1XeUqlRjrc1zq7s4mkGELPamYvQTZmAgCLcBGAsYHQ/s1600/Westinghouse%2Bphoto%2Bfor%2Bblog.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="481" data-original-width="860" height="221" src="https://1.bp.blogspot.com/-J0ON5x5axvI/XotF-sNQflI/AAAAAAAAA5U/N1XeUqlRjrc1zq7s4mkGELPamYvQTZmAgCLcBGAsYHQ/s400/Westinghouse%2Bphoto%2Bfor%2Bblog.jpg" width="400" /></a></div>
<br />
Normally, I'm the kind of person advertisers hate. And if they don't hate me, it's only because they don't know that I have a remarkable ability to read a newspaper or magazine from cover to cover and never even notice the advertisements. Just like I can tune out the sound of my neighbor's lawnmower, or the annoying spiel I get when I'm on hold waiting for some service to answer my telephone call, or the background noise at a restaurant.<br />
<br />
However, in the March 2020 issue of <i>Nuclear News</i>, the two-page spread on the inside cover caught my eye. It displays the slogan, "We are Westinghouse." It features 22 people (23 if you count the guy cut off at the right edge), all wearing AP1000 polo shirts. And only one of them is a woman!<br />
<br />
That is about the same ratio of men to women that I faced when I was a freshman at MIT, and believe me, that was quite a few years ago! I had thought the world had changed a lot since my first year at MIT, but this spread made me wonder.<br />
<br />
I did some digging, and I am happy to report that this photo doesn't seem to be representative of Westinghouse. <a href="https://twitter.com/hashtag/wearewestinghouse" target="_blank">Other photos</a> show a higher representation of women. And the <a href="https://www.westinghousenuclear.com/about/leadership" target="_blank">current leadership of Westinghouse</a> includes 2 women who are executive vice presidents.<br />
<br />
So why, then, did Westinghouse pose a picture with 23 men and one woman? And why did they select that shot to represent who Westinghouse is? What makes this even more puzzling is that this photo is being used as part of their recruiting strategy. What message does this send to potential job candidates? Or, for that matter, what message does it send to any member of the public who sees this ad?<br />
<br />
Obviously, I can't answer these questions. Personally, I always place more importance on actions than on "eyewash," so the fact that they have women in their leadership means more to me than a photograph. Nevertheless, in this world, image and presentation mean a lot, and I find it hard to understand what motivated Westinghouse to choose the photo they chose as a representation of who they are. It could be a setback to them in their efforts to portray themselves as being at the cutting edge. <br />

<span style="color: purple;"><span style="font-size: x-large;"><b>A Second Cancellation</b></span></span></div>
<br />
It may seem somewhat parochial to write about the coronavirus from the perspective of meetings for the nuclear community, but when you think that, just a few weeks ago, the news seemed very far from most of us, thinking in terms of personal impact drives home just how quickly and aggressively this brand new phenomenon is changing all of our lives. <br />
<br />
In the beginning, most of what we heard was about things that were happening in Wuhan, China, where a new disease, quickly dubbed COVID-19, was causing illnesses and deaths. At first, the numbers seemed relatively small, but the concern quickly grew, and quarantines and cancellations began to be announced. But again, they were initially remote from most of us. However, slowly, the disease seemed to be spreading--to more people and more countries--and the announcements hit closer to home.<br />
<br />
The first announcement that affected my personal plans was the postponement of the Pacific Basin Nuclear Conference (PBNC) originally scheduled for
April in Cancun, Mexico, that I wrote about in <a href="https://nukepowertalk.blogspot.com/2020/02/coronavirus-hits-nuclear-event.html" target="_blank">my last blog only a week ago</a>.<br />
<br />
I could not have guessed when I wrote that blog that I would see another cancellation of a nuclear event only a
week later. On Thursday, March 5, the U.S. Nuclear Regulatory
Commission (NRC) <a href="https://www.nrc.gov/public-involve/conference-symposia/ric/" target="_blank">issued a notice that they were cancelling the annual Regulatory Information Conference (RIC)</a>, originally scheduled for next wee<span style="font-family: "times new roman" , serif;">k. </span> <br />
<br />
NRC's official notice states that, "In recent days, a number of organizations and presenters have changed their attendance plans, with indications that others would reach similar decisions in coming days."<br />
<br />
Once again, this is an understandable, but disappointing turn of events. The NRC's RIC has become one of the most important nuclear conferences. It always draws a wide attendance from all over the U.S. and from a number of other countries, and it provides an excellent overview of a variety of nuclear regulatory and related issues.<br />
<br />
While the PBNC announced a postponement of their meeting (until October), the NRC has cancelled the meeting outright. The next RIC will be held in March 2021.<br />
<br />
Of course, these 2 meetings are very small events compared to some of the large and well-known meetings and events that announced cancellations in the last couple of weeks, so I am not trying to imply that there is something special or different going on with regard to nuclear meetings. And of course, many people around the world are enduring far more
serious consequences of this disease than the cancellation of a
meeting--deaths, illness, quarantines, worry, economic impacts, school closures, and so much more. It is just that, as I said, the news always seems more real when it starts affecting our individual lives and our plans. <br />
<br />
So, for all the more serious reasons, I hope that a way is found to beat back this modern-day plague. But I still can't help but miss this spring's RIC and PBNC. <br />
<br />

<span style="font-size: x-large;"><span style="color: purple;"><b>A Major Nuclear Conference is Postponed</b></span></span></div>
<br />
I should have known that, in our highly interconnected world, the recent coronavirus outbreak would start hitting in unexpected places. COVID-19, as it is officially called, originated in Wuhan, China, a place that not many people I know have ever visited. So initially, it seemed remote. A serious disease, to be sure, but, I assumed, not one that most of us had to worry about.<br />
<br />
Pretty quickly, though, that perspective was shattered. More people than I'd guessed did visit Wuhan, and people from Wuhan traveled to other places as well, so the disease started to appear in spots all over the globe. Furthermore, with so many manufactured products coming from China, reports of impacts on numerous industries began to surface. This was followed by rumblings that there would be effects on the stock market--effects that we saw realized in the past few days.<br />
<br />
And then, the impacts of the virus hit even closer to home. We learned that one of our relatives was on the Westerdam, the Holland America Line ship that wandered around the Asian waters for days trying to find a port that would allow them to land. Even though, as it turned out in the end, the one report of a case of the virus on that ship was false. Our relatives are home safely now, but not before enduring a lengthy and uncomfortable ordeal.<br />
<br />
But still, it was only February, so events that were scheduled to take place a couple of months from now were not on my radar screen. Thus, I was not prepared for a message from the Mexican organizers of the upcoming <a href="https://www.pbnc-2020.mx/" target="_blank">Pacific Basin Nuclear Conference (PBNC)</a> that was scheduled to be held in Cancun in late April. The message proposed to the Pacific Nuclear Council (PNC), on which I serve, that the conference should be postponed. Surely, I thought, this outbreak would be contained and everything would be fine by then. However, the PBNC specifically focuses on countries in Asia and the Americas, and with the number of cases still growing in China and South Korea, and with speakers and attendees needing to make travel plans, it became clear that the success of the conference was in jeopardy. A number of potential speakers and attendees might not even be able to leave Asia. Others might be exercising caution and restricting all foreign travel.<br />
<br />
Clearly, the appropriate thing to do was to postpone the conference, and the organizers did so. The new dates are October 18-22. The place is the same (Cancun, Mexico). Hopefully, the virus will have been contained by then and the conference will be able to take place and will be a success. In the meantime, the conference organizers have extended the paper submission dates, so I'd like to encourage people to consider submitting papers and to plan to attend in the fall. It is one of the major international nuclear conferences, and attracts attendees from around the Pacific Rim and elsewhere. The resort venue is an added attraction. I commend the Mexican Nuclear Society for their decision to postpone the conference and wish them a highly successful conference in October.<br />

<span style="color: purple;"><span style="font-size: x-large;"><b>Another Reactor Closes</b></span></span></div>
<br />
The news today comes as no surprise. Fessenheim 1, France's oldest operating nuclear power plant, was <a href="https://world-nuclear-news.org/Articles/Frances-oldest-reactor-ends-power-generation" target="_blank">disconnected from the grid</a> this past weekend, completing 42 years of operation.<br />
<br />
This action is a consequence of a decision made under the administration of the former French president, Francois Hollande, to limit the nuclear share of the national electricity generation mix to 50% by 2025, and to cap nuclear power generation at the level that existed in 2014. That decision clearly meant that France would have to shut down older reactors as any new reactors went online.<br />
<br />
I want to emphasize that the age of the reactor was not the primary reason for the shutdown. Yes, it is the oldest reactor, and yes, when the U.S. first licensed reactors, they were only licensed for 40 years. But the U.S. law has since been changed, and nuclear power plants have demonstrated that, with proper maintenance and upgrades, they can continue operating safely for more than 40 years. <br />
<br />
At the time the French law limiting the share of nuclear generation was passed, Electricite de France (EDF) was in the process of building a new nuclear power plant at Flamanville, a 1650 MWe EPR. The completion of the unit has been delayed a number of times--which also delayed the closure of Fessenheim--but is now nearing completion. However, somewhat surprisingly, Fessenheim is being closed a couple of years before Flamanville is expected to go into operation. The grid operator has offered assurances that the gap between the closure of Fessenheim and the opening of Flamanville will not affect the security of France's energy supply. The grid operator points to the commissioning of a new combined cycle gas plant, the development of renewable energy sources, and new grid interconnections with the U.K. and Italy. <br />
<br />
Nevertheless, I think a lot of people would agree that shutting Fessenheim before Flamanville opens is a short-sighted decision. France is in the process of closing its remaining coal-fired power plants. Therefore, any further delays in the commissioning of the Flamanville plant, or any other unexpected closures of other plants, could threaten the security of France's energy supply. <br />
<br />
And while past performance may not necessarily provide an accurate prediction of the future, it is no secret that the construction of the Flamanville reactor has experienced numerous delays. The plant was originally scheduled to go into operation in 2013. If the current plan to begin operation in 2022 is achieved, that is still a 9-year delay. <br />
<br />
Now that France has made this decision, I of course hope they are able to maintain the current schedule for the start-up of the Flamanville plant, and that nothing happens to threaten France's energy supply. But, even though I loved living in France, I'm sort of glad I'm not living there now. Just in case! <br />

<span style="font-size: x-large;"><b><span style="color: purple;">Status and Prospects</span></b></span></div>
<br />
The New Year is always a time for reflection on the past and the future. And a new decade (if you count 2020 as the start of a decade) doubles the incentive to try to look at where things are headed for nuclear power. <br />
<br />
As always the picture for nuclear power is very mixed, and depending on which report you read which day, you can conclude either that nuclear power is on its way out, or that nuclear power is poised for great things ahead. I try to stay away from making predictions--there always seem to be too many moving parts--but I thought it might be interesting to summarize a few facts--things that are happening now in the nuclear power industry around the world--and to try to put them in perspective.<br />
<br />
For inspiration, I turned first to 2 recent articles on the World Nuclear Association (WNA) website, <a href="https://www.world-nuclear.org/information-library/current-and-future-generation/plans-for-new-reactors-worldwide.aspx" target="_blank">Plans for New Reactors Worldwide</a>, and <a href="https://www.world-nuclear-news.org/Articles/Reactor-shutdowns-outweigh-start-ups-in-2019" target="_blank">Reactor Shutdowns Outweigh Start-ups in 2019</a>. Taken together, these might appear to be confusing--2019 saw a decrease in the number of reactors, but on the other hand, nuclear power capacity worldwide is anticipated to increase in the coming years. <br />
<br />
<div style="text-align: left;">
When you peel back the layers, you begin to see that there are a number of elements involved in what is happening. While there were more shutdowns than startups in 2019, it is important to note that there were still a number of startups. Furthermore, most of the shutdowns had been planned for some time and were based on the ages of the plants, government subsidies for competing sources and wholesale market economics (at least in the U.S.), or on national plans to reduce the use of nuclear power in some countries. Most of the startups in the past year were not surprises either. They
were largely in Russia and China, both of which have aggressive nuclear
power programs. </div>
<br />Likewise, many of the plants listed as being under construction are in Russia and China, as well as elsewhere in Asia. The WNA article on future plans identifies about 50 reactors under construction. It also notes that, in the past, nuclear power plant shutdowns have roughly been balanced by new units starting operation: in the last 20 years, from 1998-2018, they indicate that 89 reactors were shut down and 98 new reactors started operation; and looking ahead, one prediction is that 154 existing reactors will close in the next 20 years (by 2040), while 289 may come online by 2040. The WNA article on plans for new reactors also cites the extensions of reactor operating lifetimes in the U.S. and other countries as a positive development in sustaining the nuclear contribution to electricity supply, and both articles mention power uprates in several countries. I would also particularly highlight the recent approval by the U.S. Nuclear Regulatory Commission (NRC) of the first applications for <a href="https://www.axios.com/americas-aging-nuclear-plants-2ba73bcf-4b45-458b-9fca-40a9d013e997.html" target="_blank">license extensions from 60 to 80 years</a>. <br />
<br />
Of course, predictions are always subject to a lot of change--changes in governments and national (and sometimes, local) policies, changes in public opinion, a major nuclear accident, shutdowns of fossil fuel plants, decreasing costs of renewable energy options, technological developments in nuclear technology, and much more, can all alter these projections. And the changes can be positive or negative. Recently, concerns about climate change are causing some countries to revisit past anti-nuclear policies. But historically, a number of active construction projects have failed to be completed, especially in the United States, but also elsewhere; and sometimes, plants have been shut down even after license renewals were granted. Therefore, it is too soon to tell whether the current trends will be sustained over a 20-year period.<br />
<br />
Other factors that neither of these articles cite is the potential role of some of the advanced nuclear technology under development. Current R&D is focusing a lot on <a href="http://ansnuclearcafe.org/2020/01/09/smr-progress-takes-off-for-five-developers/#sthash.lre8Kv6S.dpbs" target="_blank">small modular reactors </a>(SMRs) and even <a href="https://www.energy.gov/ne/articles/big-potential-nuclear-micro-reactors" target="_blank">micro-reactors</a>, and there are also a number of projects focused on alternatives to the current light water reactor technology. In the U.S., some specific causes for optimism include the recent Congressional budget <a href="https://www.nei.org/news/2019/2019-congressional-nuclear-spending-bill" target="_blank">appropriation for fiscal year 2020 that provides a 12.5% increase</a> in funding for nuclear projects and an <a href="https://www.nrc.gov/reading-rm/doc-collections/news/2019/19-064.pdf" target="_blank">early site permit for SMRs</a> at TVA's Clinch River site issued by the NRC. <br />
<br />
This work is focused mostly on the longer term, and some of it, especially the micro-reactors, is focused on applications other than power to the electricity grid. Therefore, this work quite rightly has not been incorporated into the 20-year prediction offered by WNA. However, in the longer term, some of this work could result in a new generation of reactors that would be appropriate for providing power to the grid, and that might address some of the concerns, such as the high cost of constructing a large reactor, and the impact of an accident, that have hampered nuclear power deployment in recent years. In fact, SMRs might also be attractive for areas that are not suitable for large reactors, and thus, have the potential to lead to an expansion of the use of nuclear power.<br />
<br />
To summarize, in recent years, nuclear power seems to have regained some of the momentum that was lost after the Fukushima accident in Japan. In fact, some countries, such as Poland, that had previously had an anti-nuclear stance, are now looking seriously at incorporating nuclear power in the future. Thus, there is some reason to believe that the WNA projections are realistic. Nevertheless, experience has shown that unanticipated developments have sometimes drastically altered the short-term trends. Looking further ahead, there is considerable potential for the new technologies under development to have a significant impact in the longer term, but further effort is needed to confirm that these newer designs meet expectations about cost and safety. <br />
<br />
I know that some will be disappointed that my projections are not more definitive. Alas, I lack a crystal ball! But I remain cautiously optimistic that the WNA projections will be realized, and that current R&D will pave the way for a new generation of nuclear power in the future.<br />
<br />

<span style="color: purple;"><span style="font-size: x-large;"><b>A Scary Parallel</b></span></span></div>
<br />
I recently came across an article on bananas that reminded me of arguments about the future sources of energy. If that sounds strange, bear with me.<br />
<br />
The article pointed out that <a href="https://time.com/5730790/banana-panama-disease/" target="_blank">our supply of bananas today is virtually a monoculture</a>--almost all the bananas that are commercially marketed are of only one variety. The article goes into the history of bananas, saying that once before, we had a different monoculture, and it was basically wiped out by a disease that spread internationally. The threat raised in the article was that we are on the verge of the same thing happening again. Since I'm not an expert on bananas, I'll leave it to the reader to research the original article if they are interested.<br />
<br />
However, what struck me is how so much of the dialogue on our future energy supply proposes to cut down on options and have all our needs met by just a few sources. I think of all the bold statements I keep seeing: We have to get rid of coal. Or all fossil fuels. Or nuclear power. Solar and wind power can potentially meet all our needs.<br />
<br />
The reality for our energy supply is almost as stark as it is for our banana supply--a monoculture has a lot of potential downsides. In the energy world, the risks can come not only from something happening to a single source of power, but also from the "fit" of different energy sources into all the varied--and changing--environments and applications in our world.<br />
<br />
A few examples come to mind: While there are multiple sources of fossil fuels, some of the rare earths used for wind power are presently available from limited sources, in particular, China, so a cut-off in supply, whether for political or other reasons, could affect the ability to meet our energy needs with wind power. Likewise, the identification of a serious design flaw that requires the shutdown of a lot of operating power plants of any one type, or a political reaction, such as shutdowns of nuclear plants in Japan and Germany, can lead to impacts ranging from increased pollution to serious health and safety impacts for vulnerable segments of the population. And different geographical areas have different wind patterns, different amounts of sunshine, different sources and amounts of cooling water, different population distributions and density, etc., so not all energy sources are equal "fits" to all locations. <br />
<br />
In addition, <a href="https://www.forbes.com/sites/jamesconca/2019/11/22/can-our-global-energy-industry-weather-extreme-weather/#74bd406a3248" target="_blank">as Jim Conca points out in <i>Forbes</i></a>, changing climate and weather patterns can also affect our energy supply. In recent years, extreme winter weather has stalled the delivery of fossil fuels. Hydropower is vulnerable to river flows which can be affected by changes in climate and precipitation. Wind power is affected by temperature changes that result in changes in air pressure, and hence, in wind speeds. Climate change will also affect cloud cover, and therefore, solar power. And rises in water temperature affect the efficiency of all water-cooled power plants, including both fossil and nuclear plants. Over-reliance on any one type of technology will exacerbate any of these effects.<br />
<br />
As always, these dire warnings are not a <i>fait accompli. </i>If we identify and characterize these vulnerabilities in time, we may be able to develop ways to address some of them. However, we can't count on figuring out every possibility in advance, and we can't count on finding ways to completely address every possible risk. The simplest and most robust measure society can take is to adopt a policy of developing and using multiple sources of energy. In this way, the impacts of a short- or long-term cutoff of one source of energy, for any reason, will be limited, and the ability of the overall system to compensate for such cutoffs will be maximized.<br />
<br />
After all, a loss of bananas is one thing, but a loss of the energy that powers just about every aspect of our lives is quite another. <br />

<span style="font-size: x-large;"><span style="color: purple;"><b>The Complexities of Transportation</b></span></span></div>
<br />
I recently came across several articles related to transportation--well, very loosely related, in one case--that once again show why it is so difficult to predict the consequences of new technologies on energy use.<br />
<br />
Much of the problem has to do with human behavior. We often assume that a new technology will take cars off the road, and therefore reduce pollution and congestion. Wrong! Some recent articles on autonomous cars and on e-scooters suggest that we are finding otherwise. Rather than replacing cars, autonomous cars may be taking people out of public transportation, and e-scooters may be attractive mainly to people who would otherwise walk. <br />
<br />
One <a href="http://www.spacedaily.com/reports/Driverless_cars_could_lead_to_more_traffic_congestion_999.html" target="_blank">study on autonomous cars</a> was particularly interesting. The article reports on a survey of commuters done by the University of Adelaide questioning them on vehicle ownership and use, vehicle sharing, etc. While the people doing the study saw a significant potential for driverless vehicles to reduce traffic congestion in the long term, they discovered that commuter attitudes, the price of new technology, and other factors may make the transition a slow one. In fact, they initially foresee an adverse impact on public transport, and a likely increase in traffic congestion over the next few decades.<br />
<br />
And I note that this article didn't even address another congestion factor that I saw discussed elsewhere. In cities where parking is difficult to find and expensive, there may be a tendency to let driverless cars just wander around the streets between uses, which would greatly increase traffic congestion.<br />
<br />
Another <a href="http://www.spacedaily.com/reports/Paris_e-scooters_under_pressure_to_prove_green_credentials_999.html" target="_blank">study focused on e-scooters</a> in Paris. The biggest surprise to me was the statement that the scooters don't replace cars, they "motorize walking trips." In addition to that, the article noted a slew of of other ecological downsides. Although they are billed as carbon-free, they still require energy and materials to build, generating carbon in the process, and they have a short life span (due to both wear-and-tear and to vandalism), so must be replaced frequently. They are being rented out and left in different places, so they have to be gathered up every day and brought to an area for recharging. A lot are ending up in the river and must be retrieved. <br />
<br />
While both of these reports are from outside the US, the findings appear relevant. Certainly, Americans are known for their love affair with their automobiles, so I suspect that a survey on autonomous cars in the US would have similar results to the one in Australia. And the article on e-scooters in Paris also quoted a study in the US that showed that most e-scooters are replacing walking or biking, not automobiles. In fact, the US study showed that the electricity for charging was only a small percentage of the e-scooter's environmental impact--most of the emissions were from the materials and manufacturing, and from driving around to pick the scooters up.<br />
<br />
Obviously, both these studies could--and should--lead to efforts to address at least some of the issues raised. For example, financial incentives might be possible to counter concerns about the price of autonomous vehicles, and electric vans could be used to pick up e-scooters. But the articles do highlight the fact that introducing new technologies is not enough to achieve the expected--and desired--outcomes. Factors such as those identified in the articles need to be raised and addressed. And even with that, human nature and other factors suggest that we may have to temper our expectations about how much some of the new technologies will reduce pollution, carbon use, congestion, etc. <br />
<br />
The final article I saw recently initially looked to me like it was going to tell a different story. It addressed the <a href="http://www.spacedaily.com/reports/Chill_your_Netflix_habit_climate_experts_say_999.html" target="_blank">energy uses of streaming videos</a>. I naturally thought about all the car trips on-demand access is potentially saving compared to the "good old days" when we had to pick up DVDs at Blockbuster. Therefore, I was surprised at their conclusion that Netflix and its competitors are not as good for the environment as I would have guessed! What the article made clear was that sitting in our living rooms, we don't see that energy is required for the streaming services. And the higher the definition of our TV screens, the larger the data files that have to be streamed. As always, the article notes that there are options--higher efficiencies at the source, convincing users to choose lower resolutions, and having the streaming services use clean energy sources.<br />
<br />
While all of this may sound unduly negative, that is not my intention. My intention is only to point out that the new technologies do not operate in a vacuum, and whether or not they achieve their full potential depends a lot on whether appropriate measures are taken to address human tendencies, comparative costs, convenience, and many other factors. <br />

<span style="font-size: x-large;"><span style="color: purple;"><b>A Vital Link</b></span></span></div>
<br />
I haven't been blogging for the past month or so, in large part because I was on an extended trip. The last stop on the trip was to attend a wedding in Half Moon Bay, California in early November. I had been following the news about the wildfires in California and the deliberate power outages intended to prevent a power line from sparking more fires. However, I had never thought to check what was happening where I was going, so I was startled when the groom spoke at the reception after the ceremony and mentioned that the power in Half Moon Bay had been cut off by Pacific Gas and Electric (PG&E) until just a couple of days before the wedding!<br />
<br />
The bridal couple--and the entire wedding party--was fortunate that the power came back on in time for the festivities, but as the news made clear, the decision whether or not to shut down carried <a href="https://time.com/5710169/california-power-wildfires-pge/?utm_source=newsletter&utm_medium=email&utm_campaign=the-brief-pm&utm_content=20191025&xid=newsletter-brief" target="_blank">potential negative consequences either way</a>. I am not questioning the PG&E's decision to cut off power in some areas. As the 2018 wildfires made clear, fires sparked by downed power lines can be deadly, and the decision to cut power this year may have saved lives and millions of dollars of property. <br />
<br />
But the decision to cut off power was not without some negative consequences of its own. Other emergencies can occur (including wildfires started by lightning or human activities), and blackouts can make it harder to communicate in such circumstances--either to get information on the path of the fire or evacuation recommendations and routes, or to call for help. And a loss of power can be deadly to people with health problems. In addition, there are smaller problems, such as spoilage of food or medications during multi-day outages, that also carry potential health problems. <br />
<br />
The importance of electricity to the well-being of people today was further emphasized in another news item I read the same week on the <a href="https://www.washingtonexaminer.com/policy/energy/shutdown-of-nuclear-after-fukushima-caused-more-deaths-than-the-accident-itself-study" target="_blank">long-term impacts of the Fukushima accident in Japan</a>. This article reports on the tentative results from a study that suggests that more people died in the aftermath of the accident, from causes not directly related to the accident or tsunami, than died in the accident itself. (This is in addition to deaths attributed to the evacuation.) I should note that this study has not yet been peer reviewed, so I can't attest to the exact numbers. However, the points addressed correspond well with other articles I've read, so I think it is appropriate to explore the general issues. <br />
<br />
In this case, the concern is not just whether or not electric power is available, it is also how the electric power is being produced, and the cost of that power. So for the Fukushima accident, the response was the shutdown of nuclear power plants and the replacement of that power by fossil fuel plants. This created two health risks--first, there was an increase in air pollution, which has a detrimental effect, particularly on the elderly and people with certain illnesses. Second, these substitute sources of electricity also cost a lot more, and apparently, this resulted in some people not being able to afford the power they needed and dying from exposure to cold.<br />
<br />
Simply put, electricity is central to today's way of life. It is how many homes are heated; it is how ventilators, dialysis machines, and other lifesaving devices operate; and it is central to how we get news that may be critical to our safety, such as evacuation instructions, and how we let people know where we are. More and more, such factors need to be taken into account when decisions are made to turn off electric power plants. Of course, in the longer term, changes may be needed in our infrastructure as well. But burying power lines and making other such changes is a very expensive and long-term proposition. Until then, we need to give more thought to the consequences of turning off electric power plants and plan for ways to protect vulnerable population groups and provide backups for critical communications. <br />

<span style="color: purple;"><b><span style="font-size: x-large;">Good Intentions, Troubling Outcomes</span></b></span></div>
<br />
As many of my readers know, I occasionally highlight actions that have been taken or are being considered that have unintended consequences that either undermine the original intent, or that end up trading an improvement in one area for a negative effect on another area. I perhaps became sensitized to unintended consequences through news items that illustrated the complexity of the energy sector, where replacing one energy source with another has not always yielded the expected benefits.<br />
<br />
I recently came across several more examples of the unintended consequences associated with certain decisions or actions, covering some very different areas. Some report unintended consequences that have already occurred. Others are forward looking and report on analyses of what might happen, so there might be time to rethink some of the plans and avoid or mitigate the unintended consequences.<br />
<br />
The first I found was a study on what could happen with driverless cars when they are not in use, particularly if we move to an economy where we rely on shared vehicles. Very simply, <a href="https://news.ucsc.edu/2019/01/millardball-vehicles.html" target="_blank">self-driving cars might stay on the roads and cruise around to avoid paying parking fees</a>! Clearly, if everyone is left to their own devices, self-interest will rule. This would increase congestion--possibly a lot--and of course, result in more energy use. This is a potential scenario that should be addressed before things get out of hand, so the very recognition of the potential problem may avert it, but it is the kind of thing that we do need to think about proactively as new technologies emerge.<br />
<br />
The second issue I came across is a harder one to address. It argues that <a href="https://www.sciencedaily.com/releases/2019/02/190204124200.htm" target="_blank">environmental regulations to protect ecosystems can result in greater carbon emissions</a>. Here, the problem is that protecting ecosystems may have prevented the development of hydroelectric dams, so power needs have been met by fossil-fired power plants. In this case, it appears that decisions have been made in some cases, so reversing the problem may be more difficult. However, the evidence should provide a wake-up call for future preservation efforts. In particular, when addressing the needs for ecosystem preservation, planners need to look holistically at <span style="font-size: small;">all the needs of the community and how they can be met. </span><br />
<br />
<span style="font-size: small;">Another issue I read about involved the potential for <a href="https://www.nature.com/articles/d41586-019-01904-1" target="_blank">efforts at gender equality to have negative effects for some women</a>. This report, in <i>Nature</i> magazine, comes from the UK and refers, in part, to something called the <a href="https://www.ecu.ac.uk/equality-charters/athena-swan/" target="_blank">Athena SWAN Charter</a>, an initiative designed </span><span style="font-size: small;">to encourage and recognize commitment to advancing the careers of women
in science, technology, engineering, math and medicine (STEMM)
employment in higher education and research. While this may seem counter-intuitive, the report cites the fact that </span><span style="font-size: small;">women make up more than 70% of Athena SWAN champions, a labor-intensive role that takes time away from their research. </span><br />
<br />
<span style="font-size: small;">The final issue I want to report about today gave me a laugh, but it may not be funny. A report in <i>Science</i> magazine <a href="https://science.sciencemag.org/content/363/6425/329" target="_blank">tied the legalization of marijuana to potential worsening of air pollution</a>. </span><span style="font-size: small;"> In particular, the article claims that cannabis plants are rich sources of volatile organic compounds
that can contribute to smog. There are also concerns about workers' health due to air quality issues. One recent study suggested the more than
600 indoor pot farms located within Denver could be worsening the city's
air pollution, which already violates federal standards. </span><br />
<br />
<span style="font-size: small;">The message I draw from all these examples is that almost everything we do has multiple impacts, some good and some not so good. This includes the many things that we do in an effort to fix some problem, be it gender inequalities or environmental impacts, or to provide society with advanced technological capabilities, like self-driving cars. This doesn't mean we shouldn't have self-driving cars, or that we shouldn't attempt to address gender inequalities or environmental impacts. It simply means we need to think more about all the potential ramifications of all such initiatives, and the earlier the better. </span><br />

<span style="color: purple;"><span style="font-size: x-large;"><b>It's Complicated</b></span></span></div>
<br />
Just when you think you know that "everyone" loves renewable energy and hates nuclear power, some news pops up to recalibrate your thinking.<br />
<br />
Last week, I saw almost back-to-back news articles that upended the "conventional wisdom." The first was a report on the <a href="http://www.winddaily.com/reports/Angry_residents_send_German_wind_industry_spinning_999.html" target="_blank">opposition of German residents to the installation of new windmills</a>. The article talks about more than 600 citizen initiatives against the installations, which are central to the German goal of weaning itself from the use of coal and nuclear power. A classic case of NIMBY (Not In My Back Yard), I thought. <br />
<br />
The very next day, a news article arrived in my inbox that announced that government officials in Nye County, New Mexico, were <a href="https://lasvegassun.com/news/2019/sep/08/nye-county-officials-on-yucca-mountain-lets-sit-do/" target="_blank">open to discussing the development of a nuclear waste repository at Yucca Mountain</a>, which is located in their county. Yucca Mountain, as many people reading this blog will know, was selected decades ago as the site for the disposal of waste from U.S. nuclear power plants, but stalled due to opposition from the State of New Mexico. Wait, I thought--what about NIMBY?<br />
<br />
Now, obviously, both situations are very complicated. The brief news article on the opposition to new windmills in Germany mentions factors including a drop in government funding and the intervention of a far-right political party of climate skeptics. These factors could be pumping up the opposition. <br />
<br />
In New Mexico, of course, there is a start contrast between the views of the state and the views of the county. To date, the state views have dominated. The views of the county, of course, are not motivated by a love for nuclear power so much as they are by the economic benefits such a major facility in their county would bring. However, it is important to note that they emphasize that they would only approve the facility if the analyses show that it is safe. What they are asking at this point is only for the assessment to be done.<br />
<br />
The message I draw from this is not that the people of Nye County are opportunists. Far from it. Rather, they are pragmatists. They are insisting that safety comes first, but if the safety standards are met, they see benefits that offset the impacts on their community, such as the disruption of construction, the increase in traffic, etc. And the people of Germany are also being pragmatic. Nuclear power-related facilities generally bring a lot of high-paying jobs, and wind-power installations generally don't, so in their case, there is little benefit to offset the disruption in their communities.<br />
<br />
Admittedly, there have been cases where local communities have opposed a facility, even though it would bring jobs or other benefits, so the issue of public acceptance around any kind of large installations--power plants, waste repositories, factories, or anything else--is complicated, and there is no guarantee that the community reactions we see in these 2 cases will always occur in other cases.<br />
<br />
Nevertheless, the contrast in the reactions to the windmills in Germany and the nuclear waste repository in Nye County are instructive. Most of us tend to think mainly of the big picture, which mainly means that we think of how power plants and other facilities benefit the greater good. But we have to keep in mind that all such facilities inevitably bring some disruption to a community. In cases where the only impacts are negative ones, it is quite logical for communities to oppose these facilities. In cases where there are positive impacts as well, the local communities may be more receptive to hosting such facilities. <br />
<br />
In all cases, of course, the first focus should be on safety. The second should be on building and operating the installation to minimize any negative impacts on the community. But those measures alone may not be strong enough to combat the NIMBY factor. Ultimately, the potential benefits to a community may also be a factor in public acceptance at the local level.<br />

<span style="color: purple;"><span style="font-size: x-large;"><b>Unexpected consequences</b></span></span></div>
<br />
I continue to be struck by the number of times I've found reports that reveal an unexpected downside of current technologies--or even more so, of the advanced technologies that are supposed to help us address some of the shortcomings of the current technologies.<br />
<br />
I have recently come across several articles that revealed potential issues in the transportation sector that somewhat surprised me. Now, these are clearly not nuclear issues, so one might wonder why I am writing about them here. The fact is that the similarity to issues that have come up in the energy industry are striking and suggest that there are lessons that can be learned from other industries. <br />
<br />
The first issue I learned about concerns electric-powered automobiles. Electric vehicles have long been promoted as a transportation alternative that will result in lower vehicle emissions and cleaner air. I have been aware that this assertion is controversial, but my understanding was that the main concern revolved around the source of the electricity used to charge the batteries of electric cars. If the source was a fossil-fuel fired electric power plant, at least some of the benefits of not burning gasoline or diesel fuel would be offset by the carbon and other emissions from the power plants.<br />
<br />
A recent article, however, points to another potential concern: <a href="https://www.researchgate.net/publication/297889793_Non-exhaust_PM_emissions_from_electric_vehicles" target="_blank">particulate matter from electric vehicles</a>. This article summarizes a literature review that suggests that electric vehicles may not reduce particulate pollution as much as expected. Electric vehicles weigh more than their non-electric counterparts, and that there is a correlation between weight and non-exhaust particulate emissions.<br />
<br />
Another article I came across focused on the <a href="https://www.huffpost.com/entry/air-pollution-cars-tire-waste_n_5a6896e3e4b0dc592a0e6f8e" target="_blank">pollution from tire wear</a> from all kinds of vehicles. We all know that tire treads wear down, and as drivers, it is one of the things we have to watch to maintain our vehicles. We don't often think, however, of what happens to the tire material that wears away. This article asserts that some of it ends up in particles small enough to circulate in the air we breathe, and that this factor has not been sufficiently recognized and studied.<br />
<br />
A third article looked at the <a href="https://phys.org/news/2019-07-electric-scooters-eco-friendly.html" target="_blank">impact of electric scooters on reducing emissions</a>. While it is clear that that electric scooters use less energy and create less pollution than much larger, fossil-fueled vehicles, this article points out that the real question is what forms of transportation electric scooters replace? I was surprised that a recent survey of electric scooter riders in several European cities found that a large majority of them would have walked, biked, or taken public transportation if they didn't have an electric scooter. Only 14% said they would have used an automobile!<br />
<br />
After thinking about that, it occurred to me that the proportion of people who would have used a car might be much higher in the United States. And indeed, the article also cites a report by one of the electric scooter companies that one-third
of the electric scooter rides around the world replaces an automobile
trip. Clearly, this number may vary a lot depending on where surveys are done. That fact alone points out the complexity of predicting how much impact a new technology might have. <br />
<br />
Some of the same uncertainties surround the reports in the other articles. The article on pollution from tires indicates that the tire manufacturers claim that the tire pollution does not result in health effects. Therefore, there may be a need to look in more detail at issues of particulate pollution from tires and its health effects. Likewise, it strikes me that the correlation between vehicle weight and particulate emissions might be complex. <br />
<br />
Clearly, the fact that some issues are beginning to surface about electric scooters or electric automobiles does not suggest that we should abandon these technologies. Rather, these findings reinforce the concern I have had that it takes time to recognize the full range of impacts, positive and negative, of any new technology, and as we do recognize these impacts, that appropriate responses need to be developed. These can include further studies in some cases to fully understand and confirm the impacts, and the development of measures to respond appropriately to those impacts.<br />
<br />
In fact, most of these articles do propose some next steps. The article on tires points to an interest in developing biodegradable tires. While I'm not sure that everything that is biodegradable is healthy to breathe, that may be a step in the right direction. That same article notes the potential value of longer term efforts to reduce the use of the automobile altogether. The article on e-scooters also promotes the idea of measures that would encourage people to give up private cars. And the article on electric cars points out the need to set standards on non-exhaust emissions, and to encourage weight reduction in all types of automobiles, electric and internal combustion.<br />
<br />
The analogies to the energy industry are clear. Probably every technological development in the energy industry, from the introduction of fossil fuels, to nuclear power, to solar, wind, hydro, biofuels, etc., has started with great optimism about all its potential benefits, only to have us discover, as time goes on, that there are negative byproducts as well. I have written before about many of them. <br />
<br />
Therefore, in identifying and reporting on these types of issues, I am not implying that we should not pursue new and advanced technologies. Rather, my purpose is to serve as a reminder that every new technology--be it for energy production, transportation, or anything else--has both potential benefits and possible drawbacks. The technological community and policymakers need to be proactive in identifying and addressing any potential negative impacts of new technologies. <br />

<span style="font-size: x-large;"><span style="color: purple;"><b>Implications for Nuclear and Wind Power</b></span></span></div>
<br />
One issue that, until lately, has gotten little attention, is that of the global supply chain for some of the materials that are essential to the continued smooth operation of things that are essential to our well being and our way of life--such as the power plants that supply our electricity.<br />
<br />
Recently, people have begun to think more about such issues. The U.S. Department of Commerce (USDOC) has just published a report on <a href="http://www.world-nuclear-news.org/Articles/US-DOC-sets-out-strategy-for-crucial-commodities" target="_blank">developing a strategy to ensure secure and reliable supplies of critical materials</a>. The report identifies 35 minerals that are viewed as critical to U.S. economic and national security. The U.S. is currently dependent on other countries for more than 50% of its demand for 29 of the 35 materials. Among the 29, two are important to the energy industry--uranium for nuclear power plants, and rare earths for wind turbines. <br />
<br />
While this initially seems frightening, the situation is really more complex. Among the issues that need to be considered are whether the minerals come from close allies or from adversaries, whether there are sources in the U.S. that could be developed, or whether there are other alternatives. <br />
<br />
Although uranium is highlighted in the report, at present, 33% of our uranium comes from Canada and 19%, from Australia, both countries with which we have a strong positive relationship. Therefore, the dependency is not as alarming as for other minerals upon which we depend.<br />
<br />
The bigger problem, it seems to me, is with the rare earths, where 78% of our supply comes from China. In fact, recent articles have indicated that <a href="https://phys.org/news/2019-05-china-threat-deprive-rare-earths.html" target="_blank">China is making it clear that they are contemplating using the threat of cutting exports of rare earths</a> or imposing tariffs on them as a bargaining tool. <br />
<br />
Rare earths are actually not so rare. Rather, they are highly dispersed, so they are difficult to mine economically in most cases. And they are used nowadays in more ways than many of us realize, from a variety of consumer products, including smartphones, televisions, cameras and light bulbs, to military equipment, to windmill turbines, so any extended market disruption could have serious effects on many aspects of our economy. <br />
<br />
The USDOC study is looking for ways to address the need for rare earths and other materials. Some of the measures mentioned in the report include extracting rare earths from coal refuse and acid mine drainage and developing other alloys to replace some rare earths. Efforts are also underway to explore the possibility of extracting rare earths, as well as uranium and other elements, from seawater. <br />
<br />
In the long run, it may also be possible to develop more mined sources for rare earths outside of China. One problem in doing this, however, is that the rare earths, because they are so dispersed, <a href="https://e360.yale.edu/features/boom_in_mining_rare_earths_poses_mounting_toxic_risks" target="_blank">produce a lot of mining waste</a>, and many communities will not want such mines near them. <br />
<br />
Some analysts believe that China will not impose restrictions on the supply of rare earths yet, for fear of triggering a global initiative to find and develop alternative supplies. However, the threat looms, and the search for ways to reduce our vulnerability should be stepped up before we face a crisis. <br />
<br />
In the meantime, what are the implications for nuclear and wind power, and what should we be doing? In the case of nuclear power, I am not as worried, because so much of our uranium supply comes from strong allies. Furthermore, some of the advanced nuclear reactor designs that are under development may be able to burn more of the uranium, or may use depleted uranium or thorium. Nevertheless, efforts to increase uranium production in the U.S. would provide additional assurance of supply. <br />
<br />
In the case of wind turbines, the situation is more complicated, particularly since there is a strong push to increase the use of renewables in the U.S. and elsewhere, and much of that increase is coming from wind power. One obvious way to address this problem would be to develop alternative alloys for use in wind turbines. <br />
<br />
Another measure is to assure that we do not rely too much on any one technology for our electricity supply. This is a policy that is beneficial for a number of reasons, and has been discussed before in this blog. Such a policy means that, as we move toward a cleaner energy supply, we should be sure to keep that energy supply diversified with a balanced mix of solar, wind and nuclear power plants.<br />

<span style="color: purple;"><span style="font-size: x-large;"><b>The Role of Regulation</b></span></span></div>
<br />
Regulation has never been easy. Most of the time, it seems superfluous at best. Most of the time, most of the systems in our lives seem to work. Airplanes get to their destinations, food is untainted, and nuclear power plants hum along. If anything, regulation often seems intrusive--it costs money and it takes time away from other activities. And at worst, regulation can be excessive, or outdated, or misdirecte<span style="font-size: small;">d</span>.<br />
<br />
But the 2 recent accidents involving the Boeing 737 Max 8 point to the fact that trying to skimp on regulation, or allowing the regulated entities to have too much say in how they are regulated and inspected, can have tragic consequences. I am referring, of course, to the crash of the Indonesian Lion Air plane off the coast of Indonesia on October 29, 2018, killing all 189 people aboard, followed by the March 10, 2019 crash of the Ethiopian Airlines flight just after takeoff from Addis Ababa, killing all 157 people aboard.<br />
<br />
I will be the first to say that I'm not an expert on aviation safety, and that the investigation of the accidents is still underway, so it is premature to draw firm conclusions. However, enough facts have emerged to paint <a href="https://www.washingtonpost.com/investigations/how-the-faa-allows-jetmakers-to-self-certify-that-planes-meet-us-safety-requirements/2019/03/15/96d24d4a-46e6-11e9-90f0-0ccfeec87a61_story.html?utm_term=.5630adee30b5" target="_blank">a troubling picture of some of the practices of the Federal Aviation Administration (FAA)</a>. Among other things, the FAA had a policy that allowed aviation manufacturers to certify that their own systems complied with FAA's air safety regulations.<br />
<br />

<br />
It is of particular note that the FAA's oversight of manufacturers had been criticized by the Department of Transportation's Inspector General (IG). Among other things, the IG said at different times that <span style="font-size: small;"><span style="color: black; display: inline; float: none; font-style: normal; font-weight: normal; letter-spacing: normal; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">the FAA’s system for deciding which technologies carried the highest safety risks was not effective, that those doing the safety checks were not focusing on the potentially high-risk issues, and that </span><span style="color: black; display: inline; float: none; font-style: normal; font-weight: normal; letter-spacing: normal; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">the FAA had not adequately trained company employees to spot noncompliance with safety requirements. In its defense, the FAA has sighted its expanding and shifting role, particularly in the aftermath of the 9/11 attacks. </span></span><br />
<br />
<span style="font-size: small;"><span style="color: black; display: inline; float: none; font-style: normal; font-weight: normal; letter-spacing: normal; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">Again, I am not the one to pass any judgments on the FAA. But what is striking is that this discussion is playing out in the news at about the same time that the <a href="https://www.apnews.com/875c6dc62c554acbaa6247cfc3354617" target="_blank">nuclear industry is calling for the the Nuclear Regulatory Commission (NRC) to cut back on their inspections</a> and allow for more self-assessments by the nuclear power plant operators. </span></span><br />
<br />
<span style="font-size: small;"><span style="color: black; display: inline; float: none; font-style: normal; font-weight: normal; letter-spacing: normal; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">At the very least, the timing of this nuclear industry initiative is bad. This is not to say that NRC's regulation is perfect, or that there are no ways that that the inspection process could be made more efficient. Not at all. The message is that the two similar aircraft accidents occurring so close together provides a cautionary tale, both for aerospace regulation, and for other types of health and safety regulation. </span></span><br />
<span style="font-size: small;"><span style="color: black; display: inline; float: none; font-style: normal; font-weight: normal; letter-spacing: normal; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"><br /></span></span>
<span style="font-size: small;"><span style="color: black; display: inline; float: none; font-style: normal; font-weight: normal; letter-spacing: normal; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">Regulation can always be increased, and it can always be decreased. And I'd be the last person to say that the NRC, or any other regulatory organization, has found the perfect balance. But any changes need to be considered carefully. If self-assessments replace some of the current inspections, how will NRC assure that the utility people involved in the assessments are properly trained and that they are conducting the inspections appropriately? How will NRC review or check on the results? How will the public be assured that the same standards are being met?</span></span><br />
<span style="font-size: small;"><span style="color: black; display: inline; float: none; font-style: normal; font-weight: normal; letter-spacing: normal; text-decoration: none; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;"><br /></span></span>
<span style="font-size: small;">Regulation should certainly be open to internal change. Some changes may be spurred by technology changes, some by the identification of new risks, and some by the interest in improving efficiency and effectiveness. And there can be a role for industry self-assessment. But, as the recent aircraft crashes so dramatically and so sadly suggest, there can be a serious downside to insufficient regulatory guidance and oversight. </span><br />
<br />
<span style="font-size: small;">The NRC has usually been very careful in its decisions on what and how to regulate. In this time of heightened awareness of the tragic consequences that appear to stem in part from insufficient oversight, the NRC should be particularly sensitive to how it implements any changes in its inspection processes. </span><br />

<span style="color: purple;"><span style="font-size: x-large;"><b>The Site Today</b></span></span></div>
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://2.bp.blogspot.com/-QZIWnVeyiu8/XKDDG4A-NxI/AAAAAAAAA2c/ZTRd8oD5wVsfugoCjBYAXhMxXrr0AmMVACLcBGAs/s1600/Chernobyl%2BGM%2BS.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="300" src="https://2.bp.blogspot.com/-QZIWnVeyiu8/XKDDG4A-NxI/AAAAAAAAA2c/ZTRd8oD5wVsfugoCjBYAXhMxXrr0AmMVACLcBGAs/s400/Chernobyl%2BGM%2BS.jpg" width="400" /></a></div>
<br />
Late last October, I had the <a href="https://nukepowertalk.blogspot.com/2018/11/a-visit-to-fukushima.html" target="_blank">opportunity to visit Fukushima</a> in conjunction with a conference I was attending in Sendai, so when my personal plans this month called for a stop in Kiev, Ukraine, I just had to find a way to get to Chernobyl. Since I wasn't traveling on official business, I looked for other ways to get there. This would lead me to the first observation of many that I had in the course of visiting these two sites within a 5-month period: There are currently no public tours of Fukushima, but there is a thriving business providing commercial tours to Chernobyl.<br />
<br />
So my husband and I booked a one-day tour from Kiev to Chernobyl and back. Departure time was 8, but by the time we got to the departure point at 7:30, we noticed that there were several buses and that lines were already forming outside the buses. We were directed to one bus, where we got in line to be checked in. The paperwork included showing our passports so they could be checked against the information we had provided in advance. We also had been offered an option of renting a Geiger counter, so the numbers of the devices needed to be recorded as well. <br />
<br />
We ended up with a full busload of 46 people from 13 countries, but I discovered we were only one bus of several making the trip that day. The guide also told me this was off-season, and they had more tourists in the summer months.<br />
<br />
The trip from Kiev to the exclusion zone around Chernobyl took roughly two hours. At the first checkpoint, the tour group underwent a check-in procedure, the primary purpose of which was to try to make sure that they knew who is going in and coming out. And to make sure the people who go in do come out. We were also issued thermo-luminescent dosimeters (TLDs), whose numbers had to be entered in the roster next to our names.<br />
<br />
After the checkpoint, some of the members of the group spotted an elk standing by a body of water off the side of the road. Other than that, the only animals we saw were dogs that hang around at the checkpoints and the entrance to the cafeteria. We were warned not to touch the dogs, so I didn't, but these didn't look like wild dogs. They were clean and look well-cared for.<br />
<br />
The first stop on the tour was a small, abandoned village called Zalissya. I had never heard of this village, but we stop here because they allow us to go into some of the buildings, something they don't allow at the other stops. The village had scattered one- and two-story houses and a few other buildings, such as a school. We walked down the main road and poked our heads into one of two of the homes. After 30+ years of neglect, they are falling apart, and we had to pick our way around some damaged floorboards, and pieces of walls and ceiling that have fallen down.<br />
<br />
We then go through a second checkpoint at Leliv and detour from the main route to see an old Soviet missile defense early-warning radar site called Radar Duga-1. This is one of the sites that emitted a sharp tapping noise that caused it to be dubbed "the Russian Woodpecker."<br />
<br />
Our next stop was Kopachi, where we went into an old school building that had child-sized cots. A couple of the cots had dolls sitting on them. Our guide pointed out some spots outside the building where there are high radiation readings, and everyone had a chance to see the numbers on their Geiger counters spike.<br />
<br />
We then circled around the Chernobyl nuclear power plant site, where we saw the sarcophagus, the other now abandoned units, and the skeleton of a new unit that was under construction when the accident occurred.<br />
<br />
From there, we went to the cafeteria for the workers, where we had a quick lunch. Entry into the cafeteria requires going through a scanner to make sure no one tracks radioactive particles into where the food is being served.<br />
<br />
Following lunch, we returned to the buses and were taken to a closer point to view the sarcophagus. The current sarcophagus replaces the earlier one and still looks new and shiny. We were able to take selfies with the sarcophagus in the background, but we were warned not to take pictures of some guards we see off to one side, or to take pictures in some other directions, in particular, of the fuel storage facilities.<br />
<br />
After that, we finally reached Pripyat (also spelled Prypiat), where we got off the bus and took a long walking tour through the town. For safety reasons, we were admonished not to enter the buildings, many of which are missing most of the walls and windows on the ground floor. (Scrap aluminum was apparently valuable in the Soviet Union, and window frames were stolen.) Of course, in their eagerness to get some pictures, some people kept ignoring the instructions, and the tour guide spent much of her time trying to corral the group. Pripyat has been built to house the staff of the power plant, and is much grander than the little village we had visited, with multi-story buildings and a lot of infrastructure--administrative buildings, schools, post office, supermarket, recreational facilities, etc. The tour ended at the stadium and amusement park that had just been built and had not even officially opened at the time of the Chernobyl accident. This site boasts what is allegedly the hottest spot in the exclusion zone, and everyone had a chance to check the reading with their Geiger counters.<br />
<br />
After we got on the bus and got underway again, we passed an area of high radiation. The tour guide told us to put our Geiger counters against the window, creating a small "chorus" as they all went off at once.<br />
<br />
Our last stop was the town of Chernobyl. On our way in, we paused briefly at a monument to the liquidators of Chernobyl. It is sited just outside the firehouse from which most of the firefighters came, but the statues surrounding the monument also represent doctors and others who were involved. The statue is titled, "To those who saved the world." <br />
<br />
While Chernobyl (or Chornobyl) is still in the evacuation zone, and no one lives there permanently, it is now used to house people who are working at the plant. They work in 15-day shifts and spend their time off in Chernobyl. The utility pipes are laid out in an unusual way--they are all above ground, and they are raised over walkways and roads. The reason is that digging to bury them would release radioactive particles that have sunk into the earth.<br />
<br />
Exiting the exclusion zone requires going through the same 2 checkpoints we hit on our way in. We each went through a scanner at each stop. Apparently, the second one was more sensitive than the first. And the bus also got scanned at each stop by a hand-held scanner run under the bus. The tour guides also read our Geiger counters and gave us each a certificate showing the radiation dose recorded. Mine was 0.003 mSv, and my husband's was 0.002 mSv. <br />
<br />
With the 2-hour trip back to Kiev, the total tour is more than 12 hours.<br />
<br />
It is particularly interesting to contrast the visits to Fukushima and Chernobyl:<br />
<br />
- The 2 sites are at very different places in their recovery from the accidents. The Fukushima accident was only 7-1/2 years ago when I visited the site. The Chernobyl accident was almost 33 years ago. This difference may account, at least partly, for some of the other differences I note.<br />
<br />
- At Fukushima, the damaged units were still exposed. At Chernobyl, the damage is concealed under a sarcophagus.<br />
<br />
- The Fukushima tour spent more time on the power plant site, where we looked at where they were storing water, etc. On the other hand, we just drove past the residential and business areas. The Chernobyl tour didn't spend much time on the plant site, but did give us a close look at the residential areas. <br />
<br />
- Most of the housing and other buildings outside the site at Chernobyl is badly damaged by 30+ years of neglect and vandalism. The housing and businesses on the roads outside the Fukushima plant mostly appear to be in good shape.<br />
<br />
- You are allowed to drive through the exclusion zone around Fukushima with no checkpoints--although you can't stop. You are not able to drive through the exclusion zone around Chernobyl.<br />
<br />
- There are no public tours of Fukushima. Chernobyl has hundreds of visitors a day. <br />
<br />
- Chernobyl not only has one-day public tours, but even has tour options that last 2 or 3 days, and that include an overnight stay in the town of Chernobyl--that is, inside the exclusion zone. (Since I did not choose that option, I can't provide details on what they do with the extra time on site.)<br />
<br />
- Photography was not allowed at Fukushima. Cameras and cellphones were collected before the tour and returned afterwards. One reason was so that the accident would not become a spectacle. Photography was permitted at Chernobyl, although photography was restricted in some areas, and souvenirs were available for purchase at the end of the tour.<br />
<br />
- Our guide at Fukushima was a technical person. The guides at Chernobyl were not experts in the field. They are pretty knowledgeable, and basically did a good job, although I caught a couple of questionable statements. <br />
<br />
Overall, I learned more from the Fukushima tour, where I got a close look at some of the technical work in progress. However, getting a tour of Fukushima is just not an option for most people. The Chernobyl tour gave a different perspective, and represents the post-accident situation at a different point in time, with more of a focus on the civilian side. And the tour is available to the public (for a fee, of course, but one I thought was reasonable).<br />
<br />
While I wouldn't recommend planning a trip to Chernobyl as your next vacation, for anyone who is traveling in the area, it provides an interesting experience. (I'm not in the business of advertising for commercial businesses in this blog, but we found this tour operator on the Internet, and checked it out by looking at on-line reviews on one of the major travel sites.) And having had the opportunity to see both sites within a short period of time really provided a very special perspective. <br />

<span style="color: purple;"><b><span style="font-size: x-large;">Growing Recognition that Nothing is Free</span></b></span></div>
<br />
For a long time now, I have been harping on the point that the sun and the wind may be free, but collecting it and using it requires resources and produces wastes. That is not to say that solar and wind energy are bad, but just that the impacts need to be understood and considered when making decisions on energy alternatives.<br />
<br />
Therefore, I was glad to see several recent articles that recognized the same thing. The first was actually a news item in the Daily Caller from last August that I just recently saw, reporting on <a href="https://dailycaller.com/2018/08/06/solar-panels-fire-europe/" target="_blank">solar panels catching fire in an apartment complex in Holland</a>. This in itself illustrated an issue that isn't often discussed--that there are some safety risks associated with all technologies, including solar and wind technologies.<br />
<br />
But of more interest was the fact that the article went on to discuss other potential issues associated with solar power, including a report by Environmental Progress, a group led by Michael Shellenberger, claiming that solar panels create 300 times more toxic waste per unit of electricity generated than nuclear power plants. While I haven't seen the study and can't vouch for the exact numbers, I have long been concerned about the need for heavy metals in the production of solar panels. The Daily Caller article goes on to say that Japan is already experiencing problems in dealing with the growing amount of waste from solar panels.<br />
<br />
The same week, I came across an article from a group called Interesting Engineering that addressed the <a href="https://interestingengineering.com/is-storing-nuclear-waste-at-yucca-mountain-actually-a-problem" target="_blank">question of whether storing waste at Yucca Mountain is a problem</a>. This article mainly addressed the nuclear waste problem, but in the context of the discussion, included the observation that renewable technologies, like wind and solar, also require raw materials and energy to produce the wind turbines and the solar panels. The article includes a brief comment that solar and wind are "not completely environmentally friendly" during their lifetimes. Clicking on the link on that comment brought me to pages posted by the Union of Concerned Scientists that in turn had links to the pages on the environmental impacts of each technology. While these analyses were not qualitative and may not cover everything, they mention many of the same points that have been on my mind.<br />
<br />
It has taken a long time for the euphoria over "infinite" amounts of "free," "clean" solar and wind energy to be tempered by reality. The reality does not negate the fact that solar and wind can and should be part of the future energy mix. It does, hopefully, start a dialogue that will lead to actions to be sure that the negative aspects of <u>every</u> technology are recognized and addressed from the start of the planning process for new energy systems, and that decisions are made based on a complete understanding of all the pros and cons of a technology and its alternatives.<br />

<span style="color: purple;"><span style="font-size: x-large;"><b>A Comprehensive Analysis</b></span></span></div>
<br />
<a href="http://www.oecd-nea.org/ndd/pubs/2019/7299-system-costs.pdf" target="_blank">A recent report by the OECD Nuclear Energy Agency</a> provides an analytic assessment of something that has been discussed for a long time--that there is a significant system cost to relying too heavily on intermittent renewables.<br />
<br />
The report models different levels of nuclear power and renewables with a tight carbon emission constraint. Since the load factor of variable renewable energy (VRE) sources is much lower than that of conventional fossil or nuclear power plants, a significantly higher installed capacity is needed to produce a given amount of electricity.<br />
<br />
The results of the study are consistent with observations in countries like Germany, where, despite declining generation costs and zero marginal costs for solar and wind power, the costs of electricity have risen as more renewable energy has been supplied to the grid.<br />
<br />
The study also points to other issues. For example, deploying a lot of wind and solar power with low marginal generating costs produces a significant increase in the volatility of electricity prices, which can have negative financial implications for both backup sources of electricity and for the renewable sources.<br />
<br />
One might question the credibility of a study on renewables from an agency that focuses on nuclear power, but one should keep in mind that the mission of the OECD/NEA is NOT to promote nuclear power. Its mission is to assist its member countries in developing the bases for the safe
use of nuclear energy. In fact, the membership of the OECD/NEA includes countries that are anti-nuclear,<i> e.g.</i> Ireland. So, based on my experience there as Deputy Director-General in 2004-2007, I can assure readers that any comparison of energy sources that shows a benefit for nuclear power would get careful scrutiny from the anti-nuclear members.<br />
<br />
Therefore, the results of this study should be taken seriously as countries try to move away from carbon-emitting energy sources, and should be viewed as another indication that a balanced portfolio of energy sources is essential in the future.<br />

<span style="color: purple;"><span style="font-size: x-large;"><b>Visions from the Past</b></span></span></div>
<br />
I was surprised yesterday to see in one of my emails an article published on January 20 in <i>The Atlantic</i> entitled "<a href="https://www.theatlantic.com/technology/archive/2019/01/elderly-pilots-who-could-have-flown-nuclear-airplanes/580780/" target="_blank">Why There Are No Nuclear Airplanes</a>." I have some personal history related to the concept of nuclear-powered aircraft, so this brought back some memories.<br />
<br />
As it turns out, the concept of a nuclear-powered aircraft has been considered at least twice. This article recounted the first efforts to develop nuclear powered aircraft, starting in the late 1940s and continuing through the 1950s. This was by far the larger effort, and certainly the one that should receive the most attention. <br />
<br />
However, there was a second effort in the 1970s that was much more limited and is much less known than the first initiative. <i>The Atlantic</i> article didn't cover the second wave at all. Although the second effort was shorter lived and never got beyond the very early planning stage, I thought it might be worth completing the picture by describing that effort.<br />
<br />
But first, to recap the original program. As <i>The Atlantic</i> article indicates, the 1950s concept for a nuclear-powered aircraft focused on supersonic aircraft that could stay aloft for long periods and wouldn't need refueling. The payload capacities of the aircraft at that time, however, posed a number of limitations. On the plus side, they led to the early R&D efforts on molten salt reactors, which had the ability to achieve a high power density. However, even with the high power density, the plane could not carry the additional weight of a fully shielded reactor. Therefore, the concept involved an unshielded reactor, and the pilots would have been subjected to high levels of radiation exposure. <br />
<br />
The program was ultimately cancelled in the early 1960s. By that time, the development of ballistic missiles, mid-air refueling, and longer range jet-fueled bombers largely filled the niche that nuclear-powered bombers would have filled. <br />
<br />
Fast forward another decade or so. With my freshly minted doctorate in nuclear engineering, I ended up working for Analytic Services Inc. (ANSER), a company that worked mainly for the Air Force. When I was hired, I was told that I'd work on a variety of issues, but I would be the source of expertise within the company whenever a nuclear-oriented project came up. Although that sounded intriguing, I wondered at the time if I'd ever see such a project. <br />
<br />
I didn't have long to wait. Shortly after I arrived there, ANSER was asked by the Air Force to do a study on a concept for a nuclear-powered aircraft. This concept was much different than the earlier effort. The need now was considered to be for an aircraft that could stay aloft for long periods of time for purposes such as command and control. Thus, it would only need to operate at subsonic speeds. It would also take advantage of the latest in both aircraft and nuclear reactor technology. And the concept I was to analyze definitely called for the reactor to be shielded. <br />
<br />
Well, that analysis showed that even with the larger aircraft that would be used, the weight of a shielded reactor would leave no allowance for any payload. That alone doomed the concept in this second round. (And there was no longer any consideration of exposing flight crews to an unshielded reactor.) In addition, this was the period where public concerns about the safety of nuclear power plants were beginning to emerge, and the anticipated public resistance to the idea of flying reactors over the country also dampened the enthusiasm for this project. <br />
<br />
So this time, the effort was limited to a paper study and to briefings and discussions with representatives from key Air Force and other organizations that would be likely to participate in such a project if it were to move forward. No funding was ever allocated, and no R&D was ever initiated. Thus, it is only a footnote in history. Nevertheless, it is of interest to those who follow the history of nuclear power, and it is a reminder of how some concepts can be revived in different guises as technology develops and needs evolve.<br />
<br />
At the time I did this work, much of it was classified, but when I tried to see if anything was now publicly available, I came across this <a href="https://apps.dtic.mil/dtic/tr/fulltext/u2/b008943.pdf" target="_blank">very comprehensive study</a>, which I can recommend to anyone who wishes to learn more about the brief renewed attempt to develop a nuclear-powered aircraft.<br />
