As you may have heard, the American Nuclear Society recently entered into a 50/50 joint venture with the Nuclear Energy Institute to host an annual industrywide meeting in late summer, which will replace ANS’s Utility Working Conference and NEI’s Nuclear Energy Assembly. Simply put, we are taking the best of both events to create the ultimate nuclear power meeting of the year. If you are a longtime UWC attendee, you will feel right at home in the aisles of the exhibit hall, or in the working sessions designed to tackle the shared practical challenges operators face. NEI will bring the nuclear C-suite presence along with the freshest insights on industrywide issues.

The U.S. nuclear industry is growing, and we need to get even bigger if we are going to make good on the promise of a resurgence. The auto industry has SEMA, the tech industry has CES. It’s time the U.S. nuclear industry had its top event of the year.

Fatigue has been identified as a major risk factor in industrial accidents. According to the National Safety Council, 13 percent of workplace injuries can be attributed to fatigue.¹ Other research indicates that working 12 hours per day is associated with a staggering 37 percent increase in risk of injury.² Considering fatigue was a contributing factor to major nuclear accidents at Chernobyl and Three Mile Island, it makes sense that the Nuclear Regulatory Commission imposes hefty fines to ensure strict adherence to its fatigue management regulations—particularly, Code of Federal Regulations Title 10, Part 26, “Fitness for Duty Programs.”

October 11, 2024, marked the 70th anniversary of the American Nuclear Society. Taking a long view, we have not looked back and instead have tackled challenges and moved forward with lessons learned. Whether we pull examples from energy or nonenergy aspects of our nuclear enterprise, our planet has benefited from nuclear science and technology, and ANS has been there every step of the way.

As the Society reflects on its own history, let us remember:

• The first commercial nuclear power stations started operation in the 1950s.
• Nuclear energy now provides about 9 percent of the world’s electricity from about 440 power reactors.
• Nuclear provides about 25 percent of the world’s low-carbon electricity.
• Nuclear is the world’s second-largest source of low-carbon power.
• More than 50 countries utilize nuclear energy in about 220 research reactors. In addition to research, these reactors are used for training and for the production of medical and industrial isotopes.

The Nuclear Regulatory Commission has published a proposed rule that has been almost five years in the making: Risk-Informed, Technology-Inclusive Regulatory Framework for Advanced Reactors. The rule, which by law must take its final form before the end of 2027, would establish risk-informed, performance-based techniques the NRC can use to review and license any nuclear power reactor. This is a departure from the two licensing options with light water reactor–specific regulatory requirements that applicants can already choose.

TerraPower announced today that it has signed a term sheet with ASP Isotopes Inc. as the first step of a planned investment in the construction of a high-assay low-enriched uranium (HALEU) enrichment facility and the eventual purchase of HALEU produced at the facility to fuel its Natrium fast reactors.

Seattle-based Ultra Safe Nuclear (USNC), developer of a high-temperature, gas-cooled microreactor design that has drawn interest from potential customers and research and development funding from the Department of Energy, announced yesterday that it has filed a petition for Chapter 11 bankruptcy to facilitate its sale to Standard Nuclear Inc. The filing, made in the U.S. Bankruptcy Court in Wilmington, Del., includes USNC and its subsidiaries, Ultra Safe Nuclear-Technologies, USNC-Power, and Global First Power.

With more than 40 fusion development companies announcing plans and funding, it’s hard for a newcomer to stand out, but Pacific Fusion is giving it a try. The company, based in Fremont, Calif., was founded in summer 2023 and emerged from “stealth mode” last Friday with $900 million in committed funding from investors, a team that includes people directly involved in the successful ignition experiments at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), and a technical paper that makes a case for a pulsed magnetic fusion approach to fusion energy.

Commercial nuclear power is illegal in Australia, and it has been since the 1990s. This past June, however, the country’s main opposition party announced plans to build seven commercial nuclear reactors in the 2030s and 2040s on sites presently occupied by aging coal-fired plants—should the party’s Liberal–National Coalition win power in federal elections next year. This statement has reignited a public debate regarding the potential role of nuclear energy in Australia.

In the foothills of the Rocky Mountains on the outskirts of Fort Collins, Colo.—home to Colorado State University—work began this month on a new laser facility funded by a public-private partnership. The private portion is $150 million from Marvel Fusion, announced in August 2023, while $12.5 million—the latest funding for CSU from the Department of Energy’s Office of Fusion Energy Sciences (FES)—will support the new facility as part of LaserNetUS, a laser research network operated by DOE-FES to provide access to laser facilities for multidisciplinary researchers from the United States and abroad.

Holness

The Jamaican government last week signed a memorandum of understanding with Atomic Energy of Canada Limited and Canadian Nuclear Laboratories to bring nuclear power to the island nation.

Addressing the signing ceremony at Jamaica House on October 22, Jamaican prime minister Andrew Holness said the partnership reflects the government’s unwavering commitment to diversify the country’s energy portfolio with new, clean, and sustainable alternatives.

“[It] marks a pivotal moment in Jamaica’s energy transformation as we take a bold and forward-thinking step by signing this memorandum of understanding," he said. "This move is about reducing your cost of living, a major part of it being the cost of energy."

Unit 2 at the Prairie Island nuclear power plant near Red Wing, Minn., underwent an outage in fall 2023, which included extensive work on the reactor vessel using a novel approach to replace baffle-former bolts and lower radial clevis insert bolts. The work relied on extensive analysis beforehand to determine which bolts to replace such that only the new bolts were structurally credited for performance of their safety function. This proactive approach eliminated the need for costly contingencies associated with inspections.

Nuclear reactor design and analysis never stops, and engineers have an extensive computational toolbox from which to draw for their work. Since 1979, one such tool has been the RELAP5 modeling and simulation software. Now, American Nuclear Society journal Nuclear Technology has announced plans for a special issue dedicated to RELAP5 developments and applications.

Submission of abstracts is open now; email guest editor George Mesina by November 15 to express interest.

The Nuclear Regulatory Commission will host a “comment-gathering meeting” for stakeholders involved with the agency’s University Nuclear Leadership Program (UNLP) so that NRC staff can understand their views and concerns.

Gago

The governing board of the World Association of Nuclear Operators has appointed José Gago as the new WANO chair. He was formerly the general manager and chief executive officer of the Asociacion Nuclear Asco-Vandellos (ANAV) in Spain.

Gago will succeed the current chair, Tom Mitchell, on March 1, 2025, after Mitchell completes his full six-year term in the role.

Background: Gago has been ANAV’s governor at the WANO Paris Centre’s governing board since 2012 and was elected its chairperson in 2020. He has been the president of the Spanish Nuclear Society and a member of the Foro Nuclear board of directors, and he has kept close contact with the nuclear industry, serving on several advisory boards and participating in the International Atomic Energy Agency expert missions.

Fulton Station was to be a two-unit high-temperature gas-cooled reactor that was originally planned to start commercial operation in 1981 for Unit 1 and in 1983 for Unit 2. Each reactor was to provide 1,160 MWe of power. The nuclear steam supply system (NSSS) and fuel were to be developed by General Atomics (GA), and engineering firm Stone & Webster was charged with handling the construction. The Philadelphia Electric Company (PECO) had big plans for Fulton Station, but ultimately, the plant was never built.

The latest volume in the Spark Squad comic books series was released Monday as part of national Nuclear Science Week, an international event highlighting the importance of nuclear.

The weeklong observance, held annually the third week of October each year, celebrates its 15th anniversary this year.

While further editions of Spark Squad are in development, the three existing volumes and learning activities that accompany each book can be found on the DOE’s website.

Legislative proposals focused on streamlining the U.S. nuclear energy export process have circulated on Capitol Hill for several years, notably aimed at establishing a single point of contact in the government to simplify global nuclear projects.

The most recently introduced International Nuclear Energy Act (INEA) proposal (S. 826) promotes engagement with partner nations to develop a civil nuclear export strategy and to offset China’s and Russia’s growing influence on international nuclear energy development.
