Valar Atomics is developing grid-independent nuclear energy systems for heavy industrial power, hydrogen, data-center power, and clean hydrocarbon fuel production. Its core technology is a Generation IV high-temperature gas reactor architecture using TRISO fuel, graphite moderation, and helium cooling; Ward 250 is its reactor test program. On November 17, 2025, Valar Atomics and Los Alamos National Laboratory announced that the NOVA Core achieved zero-power criticality at the Nevada National Security Site, validating key physics models for Ward 250. Founded on July 4, 2023 by Isaiah Taylor in El Segundo, California (an earlier record said 2022).
