Oklo Inc.'s multi-year HALEU contracts with Centrus Energy Corp. are as much a demand signal as a fuel deal. The agreements include enough HALEU to support up to five Aurora powerhouses for multiple years, according to Oklo, giving the advanced reactor developer a supply runway beyond its first machine.

Ohio campus first

The fuel will support the first phase of Oklo's planned 1.2 GW Ohio power campus. Deliveries from Centrus's American Centrifuge Plant in Pike County, Ohio, are scheduled to begin in 2029. Oklo's Aurora Powerhouse is a compact Generation IV sodium-cooled fast reactor that uses HALEU fuel. Oklo is backed by OpenAI founder Sam Altman.

The HALEU purchase is supported by Meta's prepayment for future Oklo power production. Meta's previously announced agreement with Oklo linked prepayment for power with advancement of project development. The arrangement ties a large corporate electricity buyer directly to the fuel supply chain for the Ohio campus.

Idaho refueling and future fleets

Oklo has allocated recovered Experimental Breeder Reactor II (EBR-II) fuel for its first Aurora powerhouse in Idaho. The Centrus agreements secure HALEU for the first phase of the Ohio campus, future Aurora deployments, and later refueling of Aurora-INL. That sequencing matters: Oklo can start with recovered material in Idaho while building a commercial HALEU supply chain for Ohio and beyond.

'Securing fuel is essential to scaling Oklo's power business beyond its first reactor in Idaho,' said Oklo CEO Jacob DeWitte. 'The agreements support initial Ohio deployments and future Aurora powerhouses.'

Demand-side implications

For the HALEU market, Oklo's contracts illustrate how advanced reactor demand is becoming concrete. A single customer has now contracted for fuel covering up to five reactors for multiple years — a volume commitment that can justify enrichment capacity additions. The deal also shows how corporate offtake, in this case Meta's prepayment, can cascade into fuel procurement.

Oklo said the effort is expected to support thousands of direct and indirect jobs at full buildout and strengthen the fuel supply chain for advanced nuclear deployment across the United States. Specific fuel volumes and pricing were not disclosed.
