    Atomic Show #324 – Jay Hakes, Author of Presidents and the Planet

    Jay Hakes, an accomplished author and historian, visited the Atomic Show to talk about his recently published book, Presidents and the Planet: Climate Change Science and Politics from Eisenhower to Bush. Sometimes referred to as “the untold story of climate change,” Hake’s book is an enlightening jaunt through a history discovered during long days in archives and Presidential libraries. Though some of the most vocal proponents of climate change action tell a history story about a public and political understanding that begins sometime during the 1980s, with the actions of people like James Hansen, the truth that Hakes discovered was that presidents Eisenhower, Kennedy, Johnson and Carter and their staffs knew there was a growing body of science indicating that increasing atmospheric concentration of CO2 was a significant problem. Hakes and I talk about the period when scientists were actively trying to determine if the atmosphere was warming or cooling and the long term confusion, some of it purposeful, that has resulted from a debate that was generally resolved by the end of the 1970s. We spoke about the odd period during the Carter Administration when there was both significant concern about the risks of atmospheric CO2 and an active program to increase coal consumption while slowing nuclear energy development to a crawl. Interestingly, Carter gave the power generation industry a chance to defend nuclear power before he produced his energy plan, but there is no evidence that the industry even mentioned nuclear’s lack of air pollution or greenhouse gas emissions. Hakes’s research showed that much of the early science and political communications about climate change originated from the Atomic Energy Commission (AEC). His research also showed that the AEC involvement led to a lengthy period when groups that classified themselves as part of the Environmental Movement took little or no interest in effectively addressing climate change. They believed it was something that only nuclear cheerleaders cared about. Sadly, we now face a bit of an opposite problem. Some vocal nuclear proponents have come to the conclusion that climate change can’t be much of a problem since so many of its activists remain adamantly opposed to using nuclear energy as a powerful tool in the effort to limit the impact of climate change. Like many nuclear energy supporters, I believe we lost a lot of time and added a much larger quantity of CO2 to the atmosphere than we would have if we had continued deploying nuclear power systems. The solution to that lost time, however, is to press forward.

    Atomic Show #323 – Julie Kozeracki, Director of Strategy, DOE Loan Programs Office

    Julie Kozeracki was the lead author for a U.S. Department of Energy strategy document titled Pathways to Commercial Liftoff: Advanced Nuclear published in September 2024. The document was the result of a multi-agency, multi-lab effort to update a previously issued report. During our conversation, Kozeracki described how the report was informed by changes in the market, by a study of experiences from other countries and other industries, and by a growing recognition of the importance of design completion in enabling cost and schedule adherence. We talked about the utility of an expanding catalog of nuclear fission power systems that can meet the needs of a more diverse customer base and also the relatively new trend of increasing electricity demand led most prominently by data center expansion but also by electrification efforts for heating, transportation and industrial uses. As others have noted, this edition of the advanced nuclear liftoff report makes a clear and compelling case for including large modern light water reactors – including, but not limited to the AP1000 – in the definition of “advanced nuclear”. But clear and compelling does not equal exclusive; the report also makes a good case for the fact that the market has room for a variety of reactor sizes and capabilities to meet the wide range of power demands of a diverse universe of customers.

    Atomic Show #322 – Westinghouse’s eVinci micro reactor

    Westinghouse’s eVinci is a 15 MWth, 5 MWe micro reactor. Westinghouse often refers to it as a nuclear battery. Unlike conventional nuclear power plants, eVinci uses no water and doesn’t produce steam. The eVinci is not “just another way to boil water.” There are no pumps in the system that moves heat out of the reactor. Instead, the system uses ~24′ long heat pipes to transfer fission heat to a heat exchanger. That device serves the same function as a combustor (burner) in a fossil fuel heated Brayton cycle gas turbine. Atmospheric air is compressed and sent through the heat exchanger where it gets hotter and more energetic. That hot, compressed gas gets expanded through a turbine, causing it to rotate. The rotating turbine is connected to a generator that produces electricity with an efficiency of about 33%. An eVinci will use an open air Brayton cycle gas turbine like those that are in a wide range of commercial applications. Gas turbines are not only well-understood devices, but they have a diverse supply chain and an experienced workforce with tens of thousands of builders, operators and maintainers. They are often manufactured by the thousands. In another departure from the conventional way of doing things, eVinci uses rotating control drums instead of insertable control rods to adjust core reactivity and operating temperature. Shutdown rods are used during transport and to provide a secondary means of shutdown. The fuel is TRISO coated particle fuel with high assay, low enriched uranium in the particles. The reactor operates in the thermal neutron spectrum with graphite as the moderator. The core isn’t in a pressurized fluid. With its simple controls, small size and passive safety case, the eVinci is designed to be able to operate autonomously. Each core will last eight years or more. Leah Crider, Westinghouse’s Vice President of Commercial Operations to the eVinci micro reactor, visited the Atomic Show to provide a system overview and to answer questions about the reactor, its history, its future, its applications and its potential impact on the energy market. I think you’ll learn something from this show. Please participate in the comments and let us know what you think, especially if you have questions that were not addressed during the show.

    Atomic Show #321 – Andrew Harmon, VP Natura Resources

    The US Nuclear Regulatory Commission issued a construction permit on September 16, 2024 to Abilene Christian University (ACU) to build a molten salt research reactor. This marked the first university research reactor approval in 30 years. It is the first liquid fuel reactor ever approved for construction by the NRC and only the second advanced reactor approved since the NRC was created in 1974. Aside: The first advanced reactor construction permit was issued to Kairos for its Hermes in December 2023. End Aside Natura Resources is the technology supplier for the important new facility. Andrew Harmon, Natura Resources Vice President of Operations and Business Development visited the Atomic Show to fill in some of the backstory about the project origins, the decision to pursue a research reactor as a step towards their ultimate goal of supplying a large number of factory-produced 100 MWe molten salt reactors, some of the major successes and challenges along the way and the level of community support that the project has attracted. Developing a major new technology in a heavily regulated industry takes more time and resources than many might imagine. In this case, it involved a consortium that includes four major university partners, an enthusiastic group of local donors, a driven energy entrepreneur with a career spent moving expeditiously and safely, a supportive Department of Energy and a growing team of innovative engineers and developers. It also required significant cooperation and engagement with the NRC. I’ll stop there and let Andrew fill in the details. I think you will enjoy this show. Please participate in the comment section. Respectful discussion and debate are welcome.

    Atomic Show #320 – Magnus Mori, Urenco

    Urenco is one of the few companies in the world that enriches uranium. It’s one of an even smaller group of enrichers that aren’t owned by the Russian, Chinese or Iranian governments. It plays a key role in the western world’s nuclear fuel cycle. That role became even more important after February, 2022. With the increasingly firm prospects of a long term increase in demand for its foundational product of low enriched uranium (LEU) and a looming demand for new enrichment products like LEU+ (low enriched uranium that has greater than 5% and less than 10% U-235 content) and HALEU (high assay, low enriched uranium with U-236 concentration of 10-20%) Urenco has embarked on a program to expand its capacity. Like most other nuclear industry participants, Urenco is a conservative company that carefully considers its investments before adding capacity that might not be needed. The nature of its production technology – incredibly sophisticated centrifuges that can spin continuously for decades if not excessively cycled – encourages even more caution in the direction of ensuring that there is demand before investing many millions into new production capacity. Magnus Mori, Urenco’s head of marketing and technical sales, visited the Atomic Show to provide greater insights and details about Urenco’s history and unusual ownership structure, the factors that influence its investment decisions and the prospects that the company sees for future demand for its products. He explained the material flows into an out of an enrichment facility, including the actual compound that are handled at various stages of the process. We spoke about the UK government’s support for new production capacity and its decision to invest in a new enrichment plant to produce HALEU. We even spoke about new businesses that use centrifuges to produce valuable medical, research and industrial materials that are not part of the nuclear energy fuel cycle. I think you’ll enjoy this show. You might even learn some new details about the nuclear fuel cycle. Please participate in the comments.

    Atomic Show #319 – Juliann Edwards, The Nuclear Company

    The Nuclear Company exited a period of operating in “stealth mode” about a month ago. That exit was sufficiently well planned and executed that it is likely that Atomic Insights readers have already heard of the company. The Nuclear Company was incorporated a year ago. Its founding team has been working diligently to build the relationships and agreements needed to accomplish their self-assigned task. The company has a goal to build an initial fleet of reactors with a capacity of 6 GWe. Those reactors will be built by a consistent team, financed using a structure whose outline will be disclosed in the coming months and using a design that has successfully completed an NRC design certification review AND has been built at least once somewhere in the world. The company is also focused on sites that have already been through the early site permit process. Their project regulatory path is close to what was initially envisioned for an entity using the one-step Part 52 process. Choose a design that has been reviewed and approved, match it with a site that has been permitted and obtain a COL based on those two development steps. The company also recognizes the acceleration opportunity associated with using existing COLs. Juliann Edwards is the company’s chief development officer. She has extensive experience and contacts within the nuclear industry and currently serves as the US chairman for Women in Nuclear. I first met her when we were both working for B&W on the mPower reactor project more than a decade ago. Juliann visited this show to tell us more about The Nuclear Company, focusing on its history, people, vision and accomplishments so far. The vision and goals are aggressive and ambitious. But they don’t require any new scientific discoveries or technological inventions. That feature doesn’t guarantee success, but it makes it a little more achievable in a realistically chosen time frame. Sufficient resources – time, talent and treasure – must be invested, but the end result seems valuable enough to attract a starting critical mass.

    Atomic Show #318 – Brian Gitt, Business Development, Oklo

    Brian Gitt, the Business Development lead at Oklo, visited the Atomic Show to describe his employer’s business model and current prospects. Oklo is an advanced fission and fuel recycling company with an expansive vision for becoming a competitive clean energy supplier. It plans to provide heat and/or electricity as a service from a fleet of small fission power plants that it owns, operates and maintains. Oklo recently became a public company through a SPAC merger with AltC, a special purpose acquisition company led by Sam Altman, a venture capital investor and the founder and CEO at OpenAI. Oklo was founded in 2013 by Jake DeWitt and Caroline Cochran, two MIT nuclear engineering graduates with a vision for building a company that could manufacture and operate smaller, simpler reactors. Recognizing that nuclear engineering skills are not the only ingredient needed to build a company, Oklo founders made an early decision to participate in an entrepreneurial immersion training program at Y Combinator, a start-up accelerator and seed stage venture capital funder. Their unique business proposition for clean energy development was compelling enough to attract serious interest from Sam Altman, who was then serving as the president at Y Combinator. He became one of the company’s earliest investors and began serving as the company Chairman. As Gitt describes, Oklo has spent the past decade preparing for the growth in clean energy demand that is coming from both the energy transition and the growing use of energy for applications like high performance data centers for applications like artificial intelligence (AI). The company also sees huge opportunities in clean energy for materials production, mining and increased manufacturing in places outside of China. For more details, you’re going to have to listen to the show. Please participate in the comment section discussion. I expect that many listeners will find this to be a valuable use of their time. Disclosure: I have a long position in Oklo’s publicly traded stock in my personal portfolio.

    Atomic Show #317 – Trey Lauderdale – Founder, Atomic Canyon

    Atomic Canyon is a six month old company that is developing AI tools to improve the efficiency of routine tasks associated with developing, licensing, building, owning and operating nuclear plants. Their first product, called Neutron, uses AI to modernize searching the Nuclear Regulatory Commission’s 52 million page collection of publicly available documents that are currently accessible through the somewhat cumbersome Agencywide Documents Access and Management System (ADAMS). Trey Lauderdale, Atomic Canyon’s founder, spent the first 15 years of his career in the digital medicine field. At an inflection point in his career, with the freedom to live anywhere, he created a decision matrix to help him and his wife choose a place to live and raise their two young sons. San Luis Obispo, CA earned the highest score, with an excellent public education system as one of the contributing factors. After finding their home and moving towards closing the purchase, Trey and his wife learned via real estate disclosure documents that they would be living within 10 miles of the Diablo Canyon Nuclear Power Plant. As members of a generation who learned most of what they new about nuclear energy from The Simpsons, they were initially leery. But they quickly realized that the plant’s skilled, dedicated and well compensated employees and its property tax payments were major reasons that the schools and other aspects of the community had earned such high scores on the “place to raise our children” decision matrix. After becoming a member of the community and conversing with local nuclear professionals, Trey decided to learn as much as he could about nuclear energy and the nuclear industry. He recognized that he and his skilled colleagues could build tools that could address obstacles that slowed work and added costs. Atomic Canyon has just announced a cooperative project with the Oak Ridge National Laboratory (ORNL) that will train ORNL’s Frontier – currently the world’s fastest supercomputer, capable of more than a quintillion calculations per second – how to understand nuclear terminology. The resulting model will not be trained on proprietary or safety related information on the design and operation of nuclear power, but it will help analyzing the deep library of regulatory guides, inspection reports, and other publicly available documents to assist in increasing safety and accountability. The products (models) created by the partnership will be open source and available to become part of the toolbox for other developers. Trey and I had a fascinating conversation. I think you will agree.

ORNL supercomputer’s new task is no sci-fi – it’s a clean energy win
