Oklo Inc. (NYSE: OKLO) ("Oklo"), an advanced nuclear technology company, today announced the U.S. Department of Energy (DOE) has approved the Nuclear Safety Design Agreement (NSDA) for Atomic Alchemy's Groves Isotopes Test Reactor in Texas under the DOE's Reactor Pilot Program (RPP).

The NSDA approval for Oklo's wholly owned subsidiary follows the announcement of the signing of the Other Transaction Agreement (OTA) for the facility in January and is a major milestone in DOE's RPP authorization pathway, designed to speed execution and help expand U.S. industrial capacity through a framework that supports swift, scalable deployment. With the NSDA approved, the facility moves into the next phase of project execution under DOE oversight by submitting its Preliminary Documented Safety Analysis (PDSA) for review.
