Oklo's Aurora Reactor Clears Major Safety Hurdle for Idaho Deployment

Oklo has reached a key stage in developing its Aurora powerhouse, a fast neutron reactor for Idaho National Laboratory. The US Department of Energy has approved the Preliminary Documented Safety Analysis for the project. This marks a significant step forward for the company's advanced nuclear technology. The Aurora powerhouse will be built at Idaho National Laboratory. It is designed to run on fuel made from fresh HALEU or used nuclear fuel. The reactor builds on the heritage of the Experimental Breeder Reactor II.

In March, Oklo received approval for its Nuclear Safety Design Agreement. CEO Jacob DeWitte called this a major milestone for Aurora-INL and for future projects. The Preliminary Documented Safety Analysis covers hazard evaluation, accident scenarios, safety controls, and design commitments.

A ground-breaking ceremony for Aurora-INL took place in September 2025. Oklo aims to use the Reactor Pilot Program to speed up deployment. The programme allows scalable generation capacity to be developed under federal oversight. The approvals and ground-breaking ceremony move Oklo closer to operating its advanced reactor. Through the Reactor Pilot Program, the company expects to gain early experience with Aurora-INL. This could pave the way for wider adoption of its nuclear technology.
