Atomic Alchemy Isotope Platform
Overview
Oklo's isotope business combines the Idaho Radiochemistry Laboratory, a planned pilot reactor in Texas, and a future multi-reactor foundry to supply critical medical, industrial, research, defense, and space isotopes.
A March 2026 NRC materials license enables initial commercial sales from Idaho. The DOE approved the Nuclear Safety Design Agreement for the Groves Isotopes Test Reactor in Lockhart, Texas on March 17, 2026, approved its Documented Safety Analysis - the facility's final safety-basis document - on July 1, 2026, and granted startup authorization on July 23, 2026 under the Reactor Pilot Program, the final step that clears Groves to load fuel, run startup tests, and proceed toward first criticality. Oklo is advancing toward first criticality at Groves while pursuing longer-term VIPR foundry plans.
