Valar Atomics, a nuclear startup based in El Segundo, California, recently became the first company in a special Department of Energy pilot program to achieve criticality, a crucial step in nuclear engineering. Criticality, the state where a nuclear reactor sustains a chain reaction, marks the initial stage in generating power through nuclear fission. This milestone, achieved with assistance from a prominent nuclear laboratory, demonstrates progress in the field of nuclear technology.
The pilot program, designed to accelerate nuclear startup milestones, targets at least three startups to achieve criticality by July 4, 2026. Valar Atomics’ success in reaching criticality showcases the potential for private-sector execution and federal collaboration in advancing nuclear engineering.
Adam Stein, Director of the Nuclear Energy Innovation program at the Breakthrough Institute, explains criticality using a domino analogy, highlighting the delicate balance required for a sustainable chain reaction in a nuclear reactor. This achievement signifies a leap forward in American nuclear innovation, emphasizing efficiency, scale, and public-private partnerships.
