OKLO’s NRC Principal Design Report Accepted for Review Under an Accelerated Timeline

Oklo announced today that the NRC has accepted for review their Principal Design Criteria (PDC) report under an accelerated timeline. The PDC report usually defines the safety, reliability and performance requirements that will underpin future reactor licensing and design efforts. Because it’s accepted early and ahead of schedule, once approved it can be referenced in future applications- meaning that Oklo won’t have to re-defend those criteria each time, which streamlines licensing and speeds deployment.

They also noted that the NRC accepted the report in just 15 days (versus the typical 30-60 days), and **the NRC expects to issue is draft evaluation by early 2026- about half the usual review time**. Legislation and regulatory modernization efforts are cited as supporting for accelerated licensing pathways.
