Kairos Power finalizes contract on HALEU for Hermes
Kairos Power has finalized a contract with the Department of Energy to receive high-assay low-enriched uranium (HALEU) from the agency for the company’s Hermes low-power demonstration reactor, currently under construction in Oak Ridge, Tenn.
In partnership with Los Alamos National Laboratory, Kairos intends to use the DOE-provided material to produce HALEU TRISO fuel pebbles for Hermes. The company views the Hermes test reactor and the fuel fabrication program as crucial to the eventual success of its power-producing Hermes 2 demonstration plant, also to be sited in Oak Ridge, and future commercial fluoride salt–cooled high-temperature reactors.
