Oklo (OKLO) just got a major green light. The U.S. Department of Energy (DOE) recently approved the Documented Safety Analysis for its Groves Isotope Test Reactor in Texas. That's a huge step forward for the company.
The DOE approval confirms the reactor's hazard evaluations, operating requirements, and safety controls. Groves will now move into the final pre-startup review. “The remaining steps are DOE’s readiness review and startup approval,” Oklo noted in the announcement. Once approved, Oklo will be able to receive nuclear fuel and work toward first criticality. The company is targeting first criticality for July 2026.
