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, then approved its Documented Safety Analysis — the facility's final safety-basis document — on July 1, 2026 under the Reactor Pilot Program. Only a DOE readiness review and startup approval remain before fuel loading; Oklo is targeting first criticality at Groves in July 2026 while advancing longer-term VIPR foundry plans.
