1. DOE Approves PDSA for Aurora-INL
The U.S. Department of Energy signed off on the Preliminary Documented Safety Analysis for Oklo’s Aurora-INL reactor under the Reactor Pilot Program, confirming its safety framework, hazard assessments, accident scenarios and design controls. This approval moves the fast-fission plant closer to construction and operational testing at Idaho National Laboratory.
2. Stock Reaction and Retail Engagement
Following the milestone, Oklo shares climbed 4.7% in overnight trading, poised to reverse a two-week decline. Retail discussion on social platforms spiked by 157% over 24 hours as investors debated bullish price targets and commercial potential.
3. Project and Fuel Details
Aurora-INL will become Oklo’s first fast-fission power plant, utilizing recovered fuel from the Experimental Breeder Reactor-II. It operates in parallel with Oklo’s Aurora Fuel Fabrication Facility in Idaho, which secured DOE clearance for its safety analysis in late 2025.
4. Regulatory Push and Capacity Goals
A recent executive order reforms the Nuclear Regulatory Commission to streamline licensing and set firm approval timelines. The administration aims to boost U.S. nuclear capacity from about 100 GW today to 400 GW by 2050, supporting advanced reactor deployments like Aurora.
