Great Britain announced last week that it will purchase land at two nuclear sites from Hitachi for £160 million ($203 million).

Chancellor Jeremy Hunt announced the deal for the sites—Wylfa in northern Wales and Oldbury-on-Severn in southwestern England—during the annual budget speech to Parliament. Under Hitachi’s ownership, the land was prepped for developing a pair of advanced boiling water reactor units, but those plans were suspended in 2019 due to economic constraints.

The Department of Energy’s Office of Clean Energy Demonstrations issued a final environmental assessment (EA) and finding of no significant impact in February for a cost-shared X-energy project to construct and operate a helium test facility (HTF) in Oak Ridge, Tenn. According to the EA, construction would begin in early 2024 and take X-energy and its contracted partner, Kinectrics, about one year to complete. the facility would then operate for six years, with the possibility of extensions for up to an additional 20 years, to test equipment for a demonstration of X-energy’s high-temperature, gas-cooled reactor technology and also to “serve the reactor community at large as the technology continues to develop and is adopted around the world.”

Three climate groups filed a motion for the immediate closure of Diablo Canyon nuclear power plant in California, saying the nuclear plant poses an “unacceptable safety risk.”

The continent of Africa and the 54 countries that share the land are an emerging force that will hold growing influence in the world’s economy by the end of this century. Throughout history, the world’s leading economies have been driven by large working-age populations, but the shift in demographics over the next 50 years will bring drastic changes to the global economy. As reported last year by the New York Times, most of the youngest countries in the world are in Africa (south/southeastern Asia and the Middle East being the other regions with young populations). This means that by 2050 and beyond, the countries with the largest working-age populations will be very different from the top economies today. The African Union understands these changes are coming and is working toward its Agenda 2063, the “master plan for transforming Africa into a global powerhouse of the future.”

March 8 is International Women’s Day, and this year the International Atomic Energy Agency is marking the occasion by bringing more than 400 women together for a two-day event on March 7 and 8: For More Women in Nuclear: IAEA Marie Sklodowska-Curie Fellowship and the Lise Meitner Programs.

The Nuclear Regulatory Commission plans to publish a proposed rule and draft guidance surrounding licenses for advanced reactors—the first regulatory framework developed uniquely for advanced technologies and designs.

NRC staff has been instructed to establish a licensing process for commercial nuclear power plants that is risk-informed, performance-based, and technology-inclusive.

Vistra this week completed its acquisition of Energy Harbor Corp., a move the company announced almost exactly a year ago with a $3.43 billion price tag.

Talen Energy announced its sale of a 960-megawatt data center campus to cloud service provider Amazon Web Services (AWS), a subsidiary of Amazon, for $650 million.

International Atomic Energy Agency director general Rafael Mariano Grossi visited Russia this week to discuss the “future operational status” of Ukraine’s Zaporizhzhia nuclear power plant with Russian president Vladimir Putin.

International Atomic Energy Agency experts have confirmed that the tritium concentration in the fourth batch of treated water released from Japan’s Fukushima Daiichi nuclear power plant is far below the country’s operational limit.

The Emirates Nuclear Energy Corporation announced last week start-up at its fourth nuclear unit at the Barakah plant in the UAE.

The plant is run by ENEC’s operating and maintenance subsidiary Nawah Energy Company. In the coming weeks, Unit 4 will be linked to the national electricity grid and undergo testing as power production is gradually increased to full capacity.

A bipartisan group of lawmakers passed legislation from the U.S. House of Representatives this week in support of nuclear energy production.

H. R. 6544 emerged from the chamber following a 365–36 vote. The legislation would speed up environmental reviews for new nuclear projects and reduce fees for advanced nuclear reactor licenses. It would also update the Price-Anderson Act, which limits the industry’s legal liability for nuclear accidents, by extending it for 40 years as well as increasing the indemnity coverage—changes advocated for by the American Nuclear Society in recent position statement updates.

New appropriations bills currently under review in the U.S. Congress include a significant funding boost for nuclear energy.

This week, ranking members of both the U.S. House and Senate released six fiscal year 2024 appropriations, including the Energy and Water Development and Related Agencies bill that has nuclear energy funding for FY 2024.

The Nuclear Engineering Department Heads Organization (NEDHO) has been sponsoring Diversity Panels since October 2022, when the inaugural meeting was hosted by the University of Tennessee Department of Nuclear Engineering. The panels were established as a distinguished speaker series by a working group led by Wes Hines, head of the UT Department of Nuclear Engineering, and Todd Allen, a former NEDHO chair and the current chair of the Department of Nuclear Engineering and Radiological Sciences (NERS) at the University of Michigan.

Allen explained that the panels are meant to be “a first step toward improving the diversity of the talent entering the nuclear science and engineering fields.” The idea came from a presentation by Andreas Enqvist, director of the nuclear engineering program at the University of Florida, at the November 2021 NEDHO meeting. According to Allen, Enqvist described “ASEE [American Society for Engineering Education] data on how poorly the nuclear engineering field was doing at getting black students to study nuclear at the B.S. level and, even worse, how few moved from B.S. to graduate programs.”

A team of engineers, physicists, and data scientists from Princeton University and the Princeton Plasma Physics Laboratory (PPPL) have used artificial intelligence (AI) to predict—and then avoid—the formation of a specific type of plasma instability in magnetic confinement fusion tokamaks. The researchers built and trained a model using past experimental data from operations at the DIII-D National Fusion Facility in San Diego, Calif., before proving through real-time experiments that their model could forecast so-called tearing mode instabilities up to 300 milliseconds in advance—enough time for an AI controller to adjust operating parameters and avoid a tear in the plasma that could potentially end the fusion reaction.

Vogtle Unit 4 synchronized and successfully connected to the electric grid on March 1, just two weeks after reaching initial criticality.

This milestone is one of the final steps to completing Southern Nuclear’s long-awaited Vogtle project, adding the second of two large-scale reactors to the United States’ fleet in as many years—the first such additions to that fleet in more than three decades.

A new engineering scholarship at Washington State University (WSU) Tri-Cities has been established by Longenecker & Associates for students interested in careers that support Department of Energy missions.

The Canadian government has announced up to C$50 million ($36.8 million) in funding for predevelopment work to study the feasibility of building 4,800 megawatts of new generating capacity at the Bruce nuclear power plant in Ontario.

The Department of Energy yesterday announced a draft environmental impact statement (EIS) on HALEU Availability Program plans to purchase high-assay low-enriched uranium under 10-year contracts to seed the development of a sustainable commercial HALEU supply chain.

Particle accelerators have evolved from exotic machines probing hadron interactions to understand the fundamentals of our world to widely used instruments in research and for medical and industrial use. For research purposes, high-power machines are employed, often producing secondary particle beams through primary beam interaction with a target material involving many meters of shielding. The charged beam interacts with the surrounding structures, producing both prompt radiation and secondary radiation from activated materials. After beam termination, some parts of the facility remain radioactive and potentially can become radiation hazards over time. Radiation protection for accelerator facilities involves a range of actions for operation within safe boundaries (an accelerator safety envelope). Each facility establishes fundamental safety principles, requirements, and measures to control radiation exposure to people and the release of radioactive material in the environment.
