Oklo signs multi-year HALEU fuel contracts with Centrus for Ohio Aurora powerhouses

Oklo said on 12 November 2026 that it has signed several definitive, multi-year purchase contracts with Centrus Energy to buy high-assay low-enriched uranium (HALEU), to be delivered out of Centrus's American Centrifuge Plant in Pike County, Ohio.

Oklo says the contracts formalise the companies' letter of intent of June 2026 and cover enough HALEU to fuel as many as five Aurora powerhouses over several years, with deliveries due to start in 2029.

The companies say Oklo will pay in advance for future HALEU deliveries and that the prepayments will help Centrus build new uranium enrichment capacity in the United States. Amir Vexler, Centrus's president and chief executive, says Oklo's prepayments add to others Centrus has already received and will help fund its buildout.

Oklo says the fuel purchase is backed by Meta's prepayment for power that Oklo will produce in future, under a previously announced agreement that links Meta's prepayment to progress in developing the project. With that money, Oklo says, it can move ahead with buying fuel for the 1.2 GW power campus it plans in Ohio, which is to include several Aurora powerhouses; the Centrus contracts cover the campus's first phase.

The companies say the agreements tie together Centrus's expansion of enrichment at Piketon, the powerhouses Oklo plans and Meta's pledge of new power supply and jobs for its own operations in Ohio.

Oklo says the HALEU will also serve later Aurora projects and refuel the Aurora-INL in future. It already holds an allocation of recovered fuel from Experimental Breeder Reactor II (EBR-II) for the first of its Aurora powerhouses, in Idaho.

Centrus says the first new centrifuge for its enrichment expansion has been completed and has begun shipping, and that its customers' contracts and commitments to buy both low-enriched uranium (LEU) and HALEU from its added capacity now come to $5.4 billion.
