DOE approves safety analysis for Oklo's Groves test reactor

The U.S. Department of Energy approved the Documented Safety Analysis for Oklo's Groves Isotope Test Reactor in Lockhart, Texas, the facility's final safety-basis document, advancing the project under the DOE's Reactor Pilot Program. The remaining steps are a DOE readiness review and startup approval, after which the facility can load fuel and begin startup testing. Oklo is targeting first criticality for Groves in July 2026.
