Valar Atomic’s Ward 250 Becomes Second Reactor to Go Critical Under DOE Pilot Program

Valar Atomics has achieved self-sustaining criticality and completed zero-power testing at Ward 250, its Gen IV tri-structural isotropic (TRISO)-fueled modular high-temperature gas reactor (HTGR), at the Utah San Rafael Energy Lab in Emery County. The project is the second advanced reactor to go critical under the Department of Energy’s (DOE’s) Reactor Pilot Program and the first DOE-authorized […] The post Valar Atomic’s Ward 250 Becomes Second Reactor to Go Critical Under DOE Pilot Program appeared first on POWER Magazine .
