Current status

A March 2026 NRC materials license enables initial commercial sales from Idaho. Groves reached first criticality on August 5, 2026 - the fifth DOE Reactor Pilot Program reactor to do so, and the first on private land - and is now in low-power testing toward R&D-scale isotope production. Management said on the August 7 earnings call that first isotope revenue is expected in early 2027, more likely from the Idaho Radiochemistry Laboratory than from Groves. Longer-term VIPR foundry plans remain in place.
