TRIGA International, the only supplier of TRIGA reactor fuel in the world, recently completed a major renovation project at its fuel fabrication facility in Romans, France. The Department of Energy, which provided both technical and financial support for the project, said the upgrades ensure the continued operation of 36 TRIGA reactors around the world, including 18 in the United States.

Advanced reactor cores are being designed for higher efficiencies and longer lifetimes, but to get there, they need high-assay low-enriched uranium (HALEU).
Enriched to between 5 and 19.75 percent fissile U-235, HALEU is packed with nuclear potential. It can be used as a feedstock for the demonstration of new fuel designs, from uranium alloys to ceramic pellets and liquid fuels. Those fuels can enable advanced reactor and microreactor demonstrations. Operating light-water reactors could potentially transition to HALEU uranium oxide fuels for extended operating cycles and improved plant economics.
