First DOE safety approval to build an advanced reactor
Reached
Oklo / US DOE — DOE's Idaho office approved the Preliminary Documented Safety Analysis (PDSA) for Oklo's Aurora-INL under the Reactor Pilot Program — a staged framework letting advanced reactors build on a federal site under DOE oversight instead of waiting on full NRC licensing. It clears the safety basis for construction (not commercial operation); Oklo pursues NRC licensing separately for commercial units.
