The President’s Special Session of the 2022 American Nuclear Society Annual Meeting in Anaheim, Calif., offered members a chance to revisit the Society’s Grand Nuclear Challenges. Introduced in 2017 and put forth by the members and the ANS professional divisions, the nine challenges identify cross-cutting technical issues to be resolved by 2030 to help address the economic, sociological, or political concerns facing nuclear energy.

Engineering, construction, and project management firm Bechtel Corporation last week announced the signing of a memorandum of understanding with Toshiba America Energy Systems and Toshiba Energy Systems & Solutions to pursue a civil nuclear power plant project in Poland.

If nuclear innovators are in a race to decarbonize, it is a race with one finish line—affordable, clean, and reliable power—and many ways to get there. Over 40 fission developers and 20 fusion developers are in the running, and while attendees of the June 13 ANS Annual Meeting executive session on Breaking Through: Assessing the Current State and Prospects of Nuclear Innovation in the Race to Decarbonize heard from representatives of just three of those companies, they presented very different designs and deployment approaches, aptly reflecting the broader diversity of nuclear power innovation.

Session chair Adam Stein, director of nuclear energy innovation at the Breakthrough Institute, welcomed representatives from an advanced non–light water reactor developer (Mike Laufer, Kairos Power), a small modular light water reactor developer (Jon Ball, GE Hitachi Nuclear Energy), and a fusion power developer (Michl Binderbauer, TAE Technologies). Together they explored the challenge of engineering a significant commercial scale-up of advanced nuclear technology by the end of the decade, tackling questions of cost, schedule, supply chain, regulation, and more.

Extending the operational life of California’s Diablo Canyon nuclear power plant beyond 2025—its scheduled year of retirement—would help the state meet its climate goals more quickly, more reliably, and more cheaply than allowing the facility to close, a new study has found.

According to Retaining Diablo Canyon: Economic, Carbon, and Reliability Implications, keeping the plant on line could not only substantially reduce California’s emissions, natural gas use, and electric power costs, but also help avoid blackouts.

Speaking on June 13 at the opening plenary of the 2022 American Nuclear Society Annual Meeting in Anaheim, Calif., Ted Nordhaus, founder and executive director of The Breakthrough Institute, said that the nuclear community has a “generational opportunity to reset both public opinion and policy with regard to nuclear energy.”

Driving the change in the discussion, Nordhaus said, are three items: the growing concern over climate change, a broader recognition that renewable energy sources are insufficient, and a “post-pandemic price shock” over rising energy prices.

A new survey conducted by Bisconti Research shows strong numbers for public support of nuclear energy and for the building of additional nuclear power plants in the United States. Unlike other surveys on nuclear energy, which have yielded varying results over time, the Bisconti survey—known as the National Nuclear Energy Public Opinion Survey—is the only poll that has consistently asked the same questions in the same context for the past four decades, making its findings especially noteworthy for the nuclear industry.

The Brussels-based nuclear energy trade association nucleareurope has published its latest Infographics, containing a variety of facts and figures on the use of nuclear energy in Europe. Some of the many interesting bits of information in the publication are highlighted below.

On June 2, Nuclear Newswire published a letter from Jose Reyes, chief technology officer at small modular reactor developer NuScale Power, to May R. Berenbaum, editor-in-chief of Proceedings of the National Academy of Sciences, regarding a research article published by PNAS two days previous. The article, “Nuclear waste from small modular reactors,” has grabbed more than a few headlines for its claim that SMRs will actually generate more nuclear waste than a standard large pressurized water reactor.

Ammonia is a carbon-free energy carrier that could be produced using thermal energy from nuclear power plants. Terrestrial Energy announced June 9 that it has signed an agreement with engineering firm KBR to explore the use of its Integral Molten Salt Reactor (IMSR) for both hydrogen and ammonia production.

Researchers at three Canadian universities are studying whether bentonite clay—used as an engineered barrier in Canada’s proposed deep geological repository—can support sulfide-producing microbes that can eat away at the canisters containing spent nuclear fuel.

The International Atomic Energy Agency convened a workshop last week to explore how nuclear techniques backed by the IAEA’s Zoonotic Disease Integrated Action (ZODIAC) initiative could be used to avoid outbreaks of monkeypox and Lassa fever. The meeting, held in Vienna, Austria, on the sidelines of the IAEA Board of Governors meeting, was organized to assist countries in using nuclear and related techniques to detect, mitigate, and understand the behavior of the viruses.

“It is important that we are reacting quickly, as things happen. I am happy that concrete work is being carried out on something before it becomes a very difficult problem,” said IAEA director general Rafael Mariano Grossi as he opened the one-day summit.

Artificial intelligence (AI) and machine learning (ML) are helping scientists, engineers, regulators, and plant decision makers in their research and development of clean energy production to achieve a net-zero carbon footprint. While this science is new in terms of actual applications, it is fostering innovation in a variety of domains, from material discovery and qualification to advanced reactor design to supporting efficiencies in current power plants and transforming the usability of nuclear power plant control rooms.

Years ago, my then boss was trying to convince me to accept an undesirable (to me) assignment, and he asked me, “Aren’t you a professional?” I wasn’t quite sure how to answer. By the textbook definition, a nuclear professional is someone who gets paid to do a job in the nuclear field. True as far as it goes, but the term means much more to me.

French utility giant EDF has announced that its NUWARD small modular reactor design will be the case study for a European early joint regulatory review led by the French Nuclear Safety Authority (ASN). Also participating in the review process will be the Czech Republic’s State Office for Nuclear Safety (SUJB) and Finland’s Radiation and Nuclear Safety Authority (STUK).

In an ANS-sponsored online event held on June 8, independent energy consultant Lake Barrett shared his perspective on the Netflix docudrama series Meltdown: Three Mile Island. Barrett, who was the Nuclear Regulatory Commission’s on-site director and senior federal official for the cleanup of the TMI Unit 2 accident in the early 1980s, countered inaccuracies in the series during an interview with ANS Executive Director/CEO Craig Piercy.

The American Nuclear Society 2022 Annual Meeting starts next week in Anaheim, Calif., and will run through June 16. ANS has named the recipients of five awards that will be presented at the meeting, as well as two new Fellows, who will be honored during the opening plenary session. Additionally, over a dozen presidential citations will be awarded during the president’s special session at the meeting.

BWX Technologies, Inc., will deliver the first microreactor in the United States under a contract awarded by the U.S. Department of Defense Strategic Capabilities Office (SCO), the company announced today. BWXT will have two years to build a transportable microreactor prototype to the SCO’s Project Pele specifications and deliver it to Idaho National Laboratory for testing under a cost-type contract valued at about $300 million.

The Nuclear Regulatory Commission and Canadian Nuclear Safety Commission have completed a first joint technical review of Terrestrial Energy’s Integral Molten Salt Reactor, the company announced earlier this week.

The IMSR was selected in December 2019 to be the first advanced non–light water nuclear reactor technology to be studied under an August 2019 NRC/CNSC memorandum of cooperation aimed at enhancing regulatory effectiveness through collaborative work on technical reviews of advanced reactor and small modular reactor technologies.

Canada’s Nuclear Waste Management Organization (NWMO) has announced that it has successfully completed a full-scale demonstration of the engineered barriers that are designed to contain and isolate Canada’s spent nuclear fuel in a deep geological repository.

In this week’s “EM Update,” the Department of Energy’s Office of Environmental Management (EM) reports that its contractor Savannah River Nuclear Solutions (SRNS) has successfully reduced degreasing solvents in the aquifer beneath the Savannah River Site in South Carolina using a technology that injects a form of iron and oil into groundwater.

“The oil attracts the Cold War[–era] cleaning solvents while the iron degrades and neutralizes the contamination,” said Shannan Lucero, SRNS manager for area closure projects.
