About Valar Atomics
Valar Atomics develops modular high-temperature gas reactors (HTGRs) using TRISO fuel, designed to be mass-manufactured rather than custom-built like conventional nuclear plants. In 2026 the company's Ward250 reactor reached criticality outside a national laboratory and powered an Nvidia AI chip. Valar is now moving from demonstration to fleet-scale reactor manufacturing for AI data centers, industrial power, and synthetic fuel production.
