Centrus Energy (LEU), a Maryland-based nuclear fuel company, said Thursday it has reached a definitive multi-year agreement to supply California-based nuclear fission company Antares Nuclear with high-assay low-enriched uranium or Haleu, with deliveries expected to commence before the end of the decade.
The contract includes prepayments from Antares to support the expanded Haleu capacity and will ensure a reliable, domestic Haleu source to support Antares' advanced reactor projects, according to a statement.
Antares is developing compact microreactors for critical missions, including those related to space and national security, and has been recently selected for different programs and demonstrations by the US Army, Air Force and Space Force, the statement said.
Meanwhile, Centrus is producing US Haleu at its American Centrifuge Plant in Piketon, Ohio, the only licensed Haleu facility in the western world. In 2025, it began a multi-billion-dollar expansion to produce Haleu and low-enriched uranium on a large scale.
