The Department of Energy’s Office of Nuclear Energy has posted a list of the advantages and challenges of using nuclear energy to power AI data centers, which some estimates suggest could consume as much as 12 percent of U.S. energy production by 2028. The DOE also posted a brief video on its YouTube channel to accompany the list.
The Department of Energy has announced its first round of conditional commitments to provide high-assay low-enriched uranium to five U.S. nuclear developers. According to the DOE, the delivery of HALEU will support the commercialization of advanced nuclear technologies, aiming to deliver secure, affordable, and reliable energy to Americans.
Nuclear start-ups Deep Fission and Deep Isolation will collaborate on the management of spent nuclear fuel from Deep Fission’s advanced underground reactors under a memorandum of understanding signed by the companies.
Nuclear Energy Agency Director General William D. Magwood IV visited Mongolia recently for a series of meetings with government representatives and to participate in discussions on nuclear energy development in the country.
Here is a recap of industry happenings from the recent past:
BWRX-300 SMR deployment partnership developed
Several U.S. utility companies and supply chain partners have formed a coalition to accelerate deployment of GE Hitachi Nuclear Energy’s BWRX-300 small modular reactor. The coalition, which has applied for $800 million in funding from the Department of Energy’s Generation III+ SMR program, is led by the Tennessee Valley Authority and includes GEH, Bechtel, BWX Technologies, Duke Energy, Electric Power Research Institute, Indiana Michigan Power, Oak Ridge Associated Universities, Sargent & Lundy, Scot Forge, other utilities and advanced nuclear project developers, and the State of Tennessee. TVA previously selected the BWRX-300 SMR for possible deployment at the Clinch River site, near Oak Ridge, Tenn. If the new coalition is awarded the requested DOE funding, TVA intends to accelerate construction of the first SMR at this site by two years, planning for commercial operation by 2033.
New commentary on the Nuclear Regulatory Commission’s proposed 10 CFR Part 53 licensing recommendations for advanced reactors argues that more work is needed to make the framework practical.
Advanced reactor company Moltex Energy Canada said it has successfully validated its waste to stable salt (WATSS) process on used nuclear fuel bundles from an unnamed Canadian commercial reactor through hot cell experiments conducted by Canadian Nuclear Laboratories.
U.K.-based Core Power has announced that it intends to develop a maritime civil nuclear program anchored in the United States with the goal of bringing floating nuclear power to market by the mid-2030s. The program, called Liberty, is to encompass the modular construction of advanced reactor technology and create the regulatory and supply chain frameworks needed to begin the mass production of floating nuclear power plants (FNPPs) on a global scale.

Mission of Gen IV International Forum is extended
A framework agreement to continue the Generation IV International Forum (GIF) beyond its scheduled February 2025 expiration was signed by representatives of the United States and the United Kingdom at November’s COP29 meeting in Azerbaijan. The new agreement, which excludes previous signatory Russia, focuses on the sharing of information and pooling of funds for advanced nuclear technologies. The agreement also sets a goal of deploying fourth-generation nuclear technology by 2030. The specific advanced technologies identified by the forum are gas-cooled fast reactors, lead-cooled fast reactors, molten salt reactors, sodium-cooled fast reactors, supercritical water–cooled reactors, and very-high-temperature reactors.
From lifting moratoriums to launching studies to labeling it as clean, state lawmakers are exploring ways to give nuclear energy a boost in 2025. Here’s a look at some of the pronuclear legislation under review.
A recent Bulletin of the Atomic Scientists article cautions that uncertainty regarding the management of wastes generated by small and advanced reactors could drive up costs, making them uncompetitive with existing light water reactor technology.
Poneman
The Harvard Gazette recently featured an interview with Daniel Poneman, former president and chief executive officer of Centrus Energy and former deputy secretary of energy. In the interview, Poneman offered his views on the “comeback” of nuclear power, artificial intelligence, safety and security issues, advanced reactors, climate change goals, and other issues of interest to the nuclear energy industry.
Climate, demand, hyperscalers: In the article, Poneman explained the nuclear comeback in terms of the converging concerns about climate change and electricity demand, as well as the issue of “hyperscalers.”
Advanced reactor developer Terrestrial Energy and Utah-based waste management company EnergySolutions announced they have signed a memorandum of understanding to collaborate on the siting and deployment of Terrestrial Energy’s integral molten salt reactor plants at EnergySolutions-owned sites.
FLiBe—a mixture of lithium fluoride and beryllium fluoride—is not an off-the-shelf commodity. The Department of Energy suspects that researchers and reactor developers may have a use for the 2,000 kilograms of fluoride-based salt that once ran through the secondary coolant loop of the Molten Salt Reactor Experiment (MSRE) at Oak Ridge National Laboratory.
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.
On October 8, the Department of Energy’s Idaho Operations Office released the draft environmental assessment (EA) Demonstration of Microreactor Experiment (DOME) Test Bed Operations. The draft EA assesses the potential environmental impacts of plans to use the containment dome of the former Experimental Breeder Reactor-II at Idaho National Laboratory’s Materials and Fuels Complex (MFC) to test multiple TRISO-fueled advanced reactor designs on a micro scale.
The Nuclear Regulatory Commission is asking for presentation proposals for a virtual workshop on the storage and transportation of TRISO and metal spent nuclear fuels for advanced reactor designs now under development.
John Kelly, ANS past president (2018–19), passed away peacefully in his sleep on October 3, 2024, in Gilbert Ariz., at the age of 70. Kelly was born on March 9, 1954, and was the eldest of Jack and Aileen Kelly’s six children.
His career, which spanned more than 40 years, began at Sandia National Laboratories in Albuquerque, N.M., where he focused on safety and severe accident analysis. His leadership led him to Washington D.C., where he served as the deputy assistant secretary for nuclear reactor technologies at the U.S. Department of Energy. Kelly played a critical role in shaping nuclear policy and guiding the world through significant events, including the Fukushima Daiichi accident in Japan. At the end of his career, he was honored to serve as the American Nuclear Society’s president. In retirement, he was actively involved with ANS in technology events and mentoring the next generation of scientists.
Kelly is survived by his wife, Suzanne; his children Julie Kelly-Smith (Byron), John A. (Sarah), and Michael (Nicole); and grandchildren Kiri and Kyson Smith and John and Maximilian Kelly. His family was his pride and joy, including his cherished dog, Covie, who brought him happiness in recent years.
In lieu of flowers, donations may be made to the American Nuclear Society or Detroit Catholic Central High School (27225 Wixom Road, Novi, MI 48374). Please designate Memorial and specify John Kelly ’72 Memorial Fund.
In honor of Kelly's commitment to ANS and to celebrate his life, his profile from the July 2018 issue of Nuclear News is published below.
The Department of Energy announced contracts yesterday for six companies to perform high-assay low-enriched uranium (HALEU) deconversion and to transform enriched uranium hexafluoride (UF6) to other chemical forms, including metal or oxide, for storage before it is fabricated into fuel for advanced reactors. It amounts to a first round of contracting. “These contracts will allow selected companies to bid on work for deconversion services,” according to the DOE’s announcement, “creating strong competition and allowing DOE to select the best fit for future work.”
