Oak Ridge National Laboratory is reporting a development in TRISO fuel research that could help evaluate high-temperature gas reactor fuels. ORNL researchers used the Spallation Neutrons and Pressure Diffractometer at the lab’s Spallation Neutron Source to make neutron scattering measurements on TRISO fuel particles containing high-assay low-enriched uranium (HALEU).

The Department of Energy's Office of Environmental Management (EM) on Tuesday announced a partnership with California-based nuclear fuel company General Matter for the potential use of the long-idle Fuels and Materials Examination Facility (FMEF) at the Hanford Site in Washington state.
According to the announcement, the DOE and General Matter have signed a lease to explore the FMEF's potential to be used for advanced nuclear fuel cycle technologies and materials, in part to help satisfy the predicted future requirements of artificial intelligence.
BWXT’s Centrifuge Manufacturing Development Facility in Oak Ridge, Tenn.
BWX Technologies announced on January 26 that it has begun operating its Centrifuge Manufacturing Development Facility in Oak Ridge, Tenn., with the purpose of reestablishing a domestic uranium enrichment capability to meet U.S. national security needs. The facility is part of a program funded by the Department of Energy’s National Nuclear Security Administration to supply enriched uranium for defense needs.

Nuclear Transport Solutions and Westinghouse have signed a strategic agreement to codevelop NTS’s Pegasus—a transport package for high-assay, low-enriched uranium fuel.
The companies signed the agreement at the British Embassy in Washington, D.C., on January 22, taking what Westinghouse called “an important step in making HALEU available to enable advanced nuclear energy in the U.S. and UK.”

On January 16, Tenn. Gov. Bill Lee, Deputy Gov. Stuart McWhorter, and officials from Laser Isotope Separation Technologies announced the company’s plans to expand in Oak Ridge, Tenn. That expansion will come with a $1.38 billion investment from LIS Technologies for what the company says will be the first commercial laser uranium enrichment plant in the United States.

Five companies are the recipients of Department of Energy awards to support the development, modification, and licensing of transportation packages for high-assay low-enriched uranium (HALEU) fuel. HALEU, which is enriched between 5 percent and 20 percent, is the type of fuel required for the operation of many of the small advanced nuclear reactors that are being designed and developed by U.S. companies.

U.K.-based Perpetual Atomics and U.S.-based QSA Global claim to have achieved a major step forward in processing americium dioxide to fuel radioisotope power systems used in space missions. Using an industrially scalable process, the companies said they have turned americium into stable, large-scale ceramic pellets that can be directly integrated into sealed sources for radioisotope power systems, including radioisotope heater units (RHUs) and radioisotope thermoelectric generators (RTGs).

Idaho National Laboratory has announced the creation of the first batch of enriched uranium chloride fuel salt for the Molten Chloride Reactor Experiment (MCRE). INL said that its fuel production team delivered the first fuel salt batch at the end of September, and it intends to produce four additional batches by March 2026. MCRE will require a total of 72–75 batches of fuel salt for the reactor to go critical.
