NRC issues preliminary safety approval for Kairos design document

摘要

The US Nuclear Regulatory Commission has given draft approval of a safety report from Kairos Power on the amount of radiation its Hermes advanced reactor could release during an accident. Hermes is a 35-MW thermal fluoride-cooled high-temperature reactor Kairos plans to build at a site near Oak Ridge, Tennessee, and be operational in 2026. The unit is planned to be a low-power demonstration reactor to test Triso fuel fabricated with Haleu. High-assay low enriched uranium is uranium which is enriched to more than 5% but less than 20% U-235, is proposed to be used by most advanced reactor developers.
