Oklo Inc. said on May 26, 2026, that the U.S. Department of Energy selected it for advanced negotiations under the Surplus Plutonium Utilization Program. The company said this designation could provide an additional pathway to source reactor fuel as domestic enrichment and fuel-fabrication infrastructure scale.

DOE Selection and Program Terms

Oklo announced in a May 26 press release that the Department of Energy chose it for advanced negotiations under the Surplus Plutonium Utilization Program. This designation marks a negotiation phase rather than a finalized award. The program aims to make designated surplus plutonium available to industry participants and enable its conversion into fuel for advanced nuclear reactors, subject to U.S. security, safeguards, and material-accountability requirements. Further agreements and approvals are needed before any material transfers or conversions proceed.

Strategic and Market Implications

Oklo said the DOE selection supports its broader fuel strategy by creating another potential pathway to source reactor fuel while domestic enrichment and fuel-fabrication infrastructure continue to develop. The company plans to collaborate with private nuclear firm newcleo under the program. Their October 2025 strategic partnership contemplates up to $2 billion of potential project capital through a newcleo-affiliated vehicle, subject to conditions and approvals.

Media coverage reported a rise in Oklo shares following the announcement. The company did not provide new numerical guidance on revenue, earnings, capital expenditures, or deployment tied to the DOE designation. If definitive agreements and regulatory approvals are reached, the collaboration and capital could expand Oklo’s fuel-sourcing options and support fuel-fabrication capacity as domestic supply chains grow.
