US advanced nuclear technology company Oklo has signed multiple multi-year contracts with uranium enrichment and nuclear fuel services provider Centrus Energy Corp for high-assay low-enriched uranium (Haleu).
Under the agreements, Oklo, which is backed by OpenAI founder Sam Altman, will make prepayments for future Haleu deliveries to support construction of new US uranium enrichment capacity with Centrus.
The agreements formalise a June 2026 letter of intent between Oklo and Centrus and include enough Haleu to support up to five Aurora powerhouses for multiple years, with fuel deliveries from Centrus’ American Centrifuge Plant in Pike County, Ohio, scheduled to begin in 2029.
