Current status

Oklo is advancing Aurora-INL under DOE's Reactor Pilot Program with construction underway. The NRC approved its Principal Design Criteria topical report in May 2026 and the DOE approved its Preliminary Documented Safety Analysis on June 11, 2026, leaving only the final Documented Safety Analysis before authorization - that final DSA has not been approved as of September 10, 2026. On its August 7 earnings call the company reaffirmed a 2028 commercial start-up target and raised 2026 capex guidance to $400-500 million to accelerate Aurora-INL procurement.
