The Nuclear Regulatory Commission and the Department of Energy have updated a 2019 memorandum of understanding to coordinate on the review of advanced nuclear reactors and advanced reactor fuel technologies.

The American Nuclear Society recently announced the designation of three new nuclear historic landmarks: the Hot Fuel Examination Facility, the Neely Nuclear Research Center, and the Oak Ridge Gaseous Diffusion Plant K-25. Today’s article, the final offering in a three-part series, will focus on the historical significance of the Oak Ridge Gaseous Diffusion Plant K-25.

In less than two weeks, the American Nuclear Society’s second annual conference of the year, the 2025 ANS Winter Conference & Expo, will come to Washington, D.C.

Today, ANS is announcing that Energy Secretary Chris Wright will be joining the list of nuclear leaders slated to speak at the conference.

The Department of Energy, Argonne National Laboratory, NVIDIA, and Oracle have agreed to a public-private partnership to deliver the DOE’s largest AI supercomputers, named Solstice and Equinox.

Lee

Summers

The Defense Nuclear Facilities Safety Board, the independent agency responsible for ensuring that Department of Energy facilities are protective of public health and safety, announced that the board’s acting chairman, Thomas Summers, has concluded his service with the agency, having completed his second term as a board member on October 18.

Summers’ departure leaves Patricia Lee, who joined the DNFSB after being confirmed by the Senate in July 2024, as the board’s only remaining member and acting chair. Lee’s DNFSB board term ends in October 2027.

Two bills were introduced in the last several weeks aiming to address nuclear power at the end of life—decommissioning plants and recycling used fuel.

The Department of Energy has a plan for private companies to “dispose of surplus plutonium”—about 19.7 metric tons in both oxide and metal forms—by “making the materials available for advanced nuclear technologies.” A Surplus Plutonium Utilization Program request for applications (RFA) issued October 21 describes the plutonium on offer, and the “thresholds” prospective applicants must meet.

Idaho National Laboratory is playing a key role in helping the U.S. Department of Energy meet near-­term needs by recovering HALEU from federal inventories, providing critical support to help lay the foundation for a future commercial HALEU supply chain. INL also supports coordination of broader DOE efforts, from material recovery at the Savannah River Site in South Carolina to commercial enrichment initiatives.

The Savannah River Site in South Carolina will begin a leak-tightness test to qualify the megavolume Saltstone Disposal Unit (SDU) 10 to store up to 33 million gallons of solidified, decontaminated salt solution produced at the site.

The U.S. Army is moving forward with additional advanced reactor programs—building on multiple military efforts already underway as well as a separate pilot program at the Energy Department.

The Department of Energy introduced a Fusion Science & Technology (S&T) Roadmap on October 16 as a national “Build–Innovate–Grow” strategy to develop and commercialize fusion energy by the mid-2030s by aligning public investment and private innovation. Hailed by Darío Gil, the DOE’s new undersecretary for science, as bringing “unprecedented coordination across America's fusion enterprise” and advancing President Trump’s January 2025 executive order, “Unleashing American Energy,” the road map echoes plans issued by the DOE’s Office of Fusion Energy Sciences (FES) in 2023 and 2024, with a new emphasis on the convergence of AI and fusion.

The road map release coincided with other fusion energy events held this week in Washington, D.C., and beyond.

Nuclear waste disposal technology company Deep Isolation is asking that the National Association of State Energy Officials (NASEO) consider how spent nuclear fuel and radioactive waste will be managed under its strategy for developing advanced nuclear power projects in participating states.

The American Nuclear Society has sent a letter to Energy Secretary Chris Wright with a set of recommendations for the Department of Energy to take to establish an effective national program to manage the storage, reprocessing, and final disposal of U.S. commercial used nuclear fuel.

Radiant Industries will build its first portable nuclear reactor at the site of the Manhattan Project in Oak Ridge, Tenn.

The land for Radiant’s new factory includes portions of the K-27 and K-29 Manhattan Project sites. The company plans to test Kaleidos, a 1-MW nuclear microreactor, in 2026, with first deployments expected soon after.

Idaho National Laboratory under the Department of Energy–sponsored Microreactor Program recently conducted a comprehensive phenomena identification and ranking table (PIRT) exercise aimed at advancing heat pipe technology for microreactor applications.

On day 10 of the government shutdown, the National Nuclear Security Administration has yet to furlough workers, but a spokesperson said that could change if members of Congress don’t agree on a continuing resolution to keep the government funded.

Should that be the case, the NNSA will resort to keeping only essential unpaid workers at some point if the government shutdown continues, an agency spokesperson told Nuclear Newswire.

Holtec International has confirmed it is canceling plans to build a consolidated interim storage facility for spent nuclear fuel in southeastern New Mexico. Named the HI-STORE CISF, the facility would have stored up to 10,000 canisters of commercial SNF on land owned by the Eddy-Lea Energy Alliance (ELEA) near the towns of Carlsbad and Hobbs.

During a Senate Environment and Public Works Committee hearing today, Ho Nieh, President Donald Trump’s nominee to serve as a commissioner at the Nuclear Regulatory Commission, was urged to maintain the agency’s independence regardless of political pressure from the Trump administration.

The Department of Energy’s Office of Environmental Management and Office of Science and the National Nuclear Security Administration issued requests for proposals last month, seeking plans from companies to build AI data centers at the Oak Ridge Reservation, the Savannah River Site, and Idaho National Laboratory.

The Department of Energy and the Nuclear Regulatory Commission will furlough thousands of employees and operate at reduced capacity under a government shutdown that started after midnight on October 1 following a failed congressional vote on a short-term funding bill.
