Oklo Inc. (NYSE: OKLO) and Standard Nuclear have signed a memorandum of understanding (MOU) to explore commercial collaboration on nuclear fuel recycling and advanced fuel manufacturing. The partnership targets the reuse of U.S. surplus plutonium and reprocessed uranium, creating a domestic supply chain for advanced reactor fuel and related isotopes. Both companies were recently chosen by the U.S. Department of Energy (DOE) as two of five firms to enter advanced negotiations under the Surplus Plutonium Utilization Program, underscoring the strategic importance of their work for national energy security and waste reduction. By linking Oklo’s planned recycling facility in Oak Ridge, Tennessee with Standard Nuclear’s TRISO fuel expertise, the alliance aims to turn legacy nuclear material into a usable resource for next‑generation reactors, space power systems, and a range of isotope‑based applications.
Oklo and Standard Nuclear Sign MOU to Explore Fuel Recycling
The MOU establishes a framework for the two companies to evaluate product specifications, commercial terms, and delivery schedules for recycled materials from Oklo’s planned fuel‑recycling facility in Oak Ridge, Tennessee. The focus will be on reprocessed uranium (RepU) and uranium‑transuranic (U/TRU) streams that could serve as feedstock for Standard Nuclear’s TRISO fuel.
Both firms were recently selected by the U.S. Department of Energy (DOE) as two of five companies for advanced negotiations under the Surplus Plutonium Utilization Program. Under the agreement, they will also explore the safe, secure, and cost‑effective conversion of U.S. surplus plutonium into advanced reactor fuel, including licensing, packaging, and transportation considerations.
“Oklo’s fuel strategy is built around turning used nuclear fuel and surplus nuclear materials into usable fuel for reactors and power plants,” said Oklo co‑founder and CEO Jacob DeWitte. “The collaboration with Standard Nuclear helps support the domestic supply chains needed to deploy advanced nuclear at scale.”
Standard Nuclear CEO Kurt Terrani added, “This partnership represents a compelling pathway to source feedstock materials for our TRISO fuel manufacturing and radioisotope power systems and is an important step in strengthening domestic fuel feedstock supply sources.”
Strategic Relevance for Advanced Nuclear Deployment
The alliance aligns with recent U.S. executive orders that aim to accelerate nuclear energy deployment and secure domestic sources of critical nuclear materials. By creating a commercial pathway for recovered uranium and plutonium, the partnership could reduce reliance on imported fuel and support the licensing of advanced reactors that require TRISO fuel.
Oklo’s broader program includes the Pluto fast‑test reactor, which is intended to demonstrate how surplus plutonium can serve as bridge fuel for advanced reactors rather than remain a long‑term disposition challenge. Standard Nuclear, the nation’s only independent developer of TRISO fuel, plans to use the recovered isotopes not only for terrestrial reactors but also for radioisotope power systems in space, defense, and industrial applications. The combined effort therefore addresses both energy generation and the growing demand for compact, reliable power sources in non‑electricity markets.
Implications for Supply Chains and Capital Planning
Oklo estimates that the United States has accumulated nearly 100,000 metric tons of used nuclear fuel, representing a sizable potential energy resource. The Oak Ridge facility is designed to recover selected materials for advanced fuel manufacturing and isotope applications, including healthcare, industrial, space, defense, and research uses.
If the collaboration progresses to commercial terms, utilities and developers could secure a domestic source of RepU and U/TRU feedstock, potentially simplifying licensing and procurement for advanced reactors. The partnership also signals to investors that the DOE’s Surplus Plutonium Utilization Program may generate new revenue streams for firms capable of converting legacy material into marketable fuel, thereby encouraging further capital allocation toward recycling infrastructure.
Key Takeaways
- Oklo and Standard Nuclear signed an MOU to explore commercial use of reprocessed uranium, uranium‑transuranic streams, and surplus plutonium for advanced reactor fuel.
- Both companies were selected by the DOE for advanced negotiations under the Surplus Plutonium Utilization Program.
- The collaboration targets a domestic supply chain that could support TRISO fuel manufacturing and isotope production for energy, space, and defense applications.
EnergyInsyte's Take
The alliance provides a concrete step toward domesticizing advanced nuclear fuel supplies, a prerequisite for scaling next‑generation reactors. Execution risks remain, particularly around licensing and transportation of surplus plutonium, so utilities should monitor DOE milestones and any forthcoming commercial terms.
