The Demand for HALEU Reaches Unprecedented Levels
The demand for High-Assay Low-Enriched Uranium (HALEU) is reaching unprecedented levels, driven largely by the rapid commercialization of advanced microreactors. Leading this charge is Oklo, whose HALEU-powered Aurora microreactor is rapidly progressing toward commercial deployment. The Aurora Powerhouse is a compact, sodium-cooled fast reactor capable of generating between 15 and 75 megawatts of electricity (MWe).
Regulatory Milestones and 2028 Debut
Oklo’s Aurora reactor is currently on track for its commercial debut at the Idaho National Laboratory (INL) by 2028. This ambitious timeline received a major regulatory boost when the Department of Energy approved Oklo’s Preliminary Documented Safety Analysis on June 11, 2026. This approval is a critical step in the licensing process, clearing the path for construction and operation.
Securing the Fuel Supply Chain
To ensure it has the necessary fuel for its expanding fleet, Oklo signed a letter of intent with Centrus Energy in June 2026. This agreement targets HALEU deliveries beginning in 2029, specifically aiming to secure enough supply to support multiple Aurora units at Oklo's planned Ohio campus. Given that Centrus is currently the sole licensed US HALEU producer, this offtake agreement is a strategic necessity.
Oklo's order book for its HALEU-requiring Aurora reactors has reached approximately 14 gigawatts (GW), bolstered by framework agreements with data center operator Switch and plans for a 1.2 GW campus in Ohio with Meta.
While these 14 GW agreements are currently non-binding, they illustrate the massive scale of HALEU demand anticipated in the data center and commercial power sectors over the coming decade. The successful deployment of these reactors will fundamentally shift the nuclear energy landscape.
