Oklo's Groves Reactor Achieves Criticality in Record Time — Oklo Inc.

Event summary

Oklo's Groves Isotope Test Reactor achieved first criticality in under a year from groundbreaking.
The project was authorized through the DOE's Reactor Pilot Program (RPP).
Groves is part of Oklo's broader effort to build domestic isotope production capabilities.
The milestone establishes a new benchmark for advanced nuclear deployment timelines.

The big picture

Oklo's achievement underscores the potential of the DOE's Reactor Pilot Program to accelerate advanced nuclear deployment. The project demonstrates that domestic nuclear development can move from design through startup in months rather than years when stakeholders collaborate on an integrated approach. This milestone could set a new standard for the industry, particularly as demand grows for clean energy and critical isotopes.
