(OKLO) U.S. Department of Energy Approves Preliminary Documented Safety Analysis of Oklo’s Aurora Fuel Fabrication Facility as Assembly Begins at Idaho National Laboratory
December 16, 2025
DOE Idaho approves PDSA for Oklo's Aurora Fuel Fabrication Facility, advancing assembly at INL and potential fuel supply.
What’s Happening
This is a regulatory/press update announcing that the U.S. Department of Energy (DOE) Idaho Operations Office approved the Preliminary Documented Safety Analysis (PDSA) for Oklo’s Aurora Fuel Fabrication Facility (A3F) and assembly has begun at Idaho National Laboratory (INL). The A3F is the first facility approved under DOE’s Fuel Line Pilot Program, and the company says this moves it closer to producing fuel for its first commercial powerhouse, Aurora‑INL.
Why It Matters
Overall sentiment is positive on execution and regulatory progress, but financials are missing. Approval signals productive collaboration with the DOE and access to legacy EBR‑II fuel, which could lower supply constraints and improve economics if later approvals and construction stay on track. Quotes from Jacob DeWitte reinforce strategic intent but don’t change the financial unknowns.
Management Moves
Management has begun A3F assembly, committed to submit and update the full Documented Safety Analysis (DSA) during construction, and aims for a readiness review before startup—no firm dates or financial metrics provided.
