Centrus Energy to Supply HALEU Fuel to Antares Nuclear, Enabling Micro Nuclear Reactor Applications for Military and Space

U.S. nuclear fuel supplier Centrus Energy has signed a multi-year contract with advanced microreactor developer Antares Nuclear, under which Centrus will supply high-assay low-enriched uranium (HALEU) to Antares. This agreement is expected to expand the application scenarios of micro nuclear reactors to locations where traditional power sources are difficult to use, such as military facilities and space environments. As part of the agreement, Antares Nuclear will make advance payments to support Centrus in expanding HALEU production capacity in the United States. Compared with conventional low-enriched uranium, HALEU contains more uranium-235, with an enrichment level above 5% but below 20%. This new type of fuel can support smaller, higher-energy-density reac...

US Centrus and Radiant Sign Long-Term HALEU Supply Agreement

On September 9, 2026, US nuclear fuel and services supplier Centrus Energy Corp. (Centrus) and mobile nuclear microreactor developer Radiant announced that the two parties have signed a multi-year definitive contract. Under the agreement, Centrus will supply high-assay low-enriched uranium (HALEU) fuel for Radiant's Kaleidos microreactor to support the deployment of multiple reactors. The agreement stipulates that Centrus will begin delivering HALEU by the end of this decade. The arrangement will add a domestic US fuel source for Radiant as it advances the commercial expansion of the Kaleidos reactor, and will also add a new HALEU customer for Centrus. The agreement also includes Ra...

X-Energy and Centrus Sign HALEU Supply Agreement, Accelerating U.S. Advanced Nuclear Fuel Supply Chain

X-Energy and Centrus Energy have signed a low-enriched uranium and high-assay low-enriched uranium supply agreement, marking a more concrete commercialization phase in fuel assurance for U.S. advanced nuclear reactors. Under the agreement, Centrus will provide uranium enrichment services at its American Centrifuge Plant in Pike County, Ohio, with the HALEU to be supplied to X-Energy's fuel subsidiary TRISO-X for the production of TRISO-coated particle fuel at its Oak Ridge, Tennessee fuel fabrication facility, serving the Xe-100 high-temperature gas-cooled small modular reactor. The significance of this agreement lies not only in the supply itself but also in its phased advance payment arrangement. X-Energy will support Centrus through advance payments...
