U.S. Oklo Inc. (NYSE: Oklo) ("Oklo") and Sweden's Blykalla AB ("Blykalla"), both advanced nuclear technology companies, today announced a strategic partnership focused on technology collaboration, supply-chain coordination, and regulatory knowledge-sharing. The agreement includes Oklo co-leading Blykalla's next investment round through an approximately $5 million commitment, a step that strengthens the companies' transatlantic collaboration to accelerate advanced nuclear commercialization.

Under a Joint Technology Development Agreement, Oklo and Blykalla will share insights on materials, components, non-nuclear supply chain sourcing, fuel fabrication, and licensing best practices across the U.S. and Sweden. Through increased cooperation and coordination, both developers aim to reduce costs and schedule risks.
This is one of the first transatlantic partnerships in the advanced nuclear reactor sector. Aligning fast reactor developers across Europe and the U.S. shows how advanced nuclear companies can work together on fuel, supply chains, and regulation to accelerate commercialization globally, based on a shared commitment to advanced nuclear technology as a cornerstone of the clean energy transition.
"This partnership strengthens the growing advanced reactor ecosystem in the face of unprecedented global demand for power," said Oklo co-founder and CEO Jacob DeWitte. "By teaming up on suppliers, materials data, and licensing insights, we can shorten critical paths to deployment and stay focused on delivering reliable, clean power to customers, while recognizing that we have more to gain from cooperating than from competing."
Together the fast reactor companies will examine shared suppliers for reactor-agnostic equipment to improve availability, schedules, and cost. Oklo may also supply select components for Blykalla's direct use to strengthen a vertically integrated, potentially cross-border, supply chain. Oklo may also provide fuel fabrication services to Blykalla. In parallel, Oklo and Blykalla will pursue targeted R&D and regulatory analysis to boost reliability and lower lifecycle costs without requiring design changes.
"Oklo and Blykalla share a practical, industrial approach to bringing advanced fission to market," said Blykalla CEO Jacob Stedman. "Coordinated component sourcing and targeted joint R&D can unlock efficiencies for both companies and help our suppliers plan for scale, regardless of which side of the Atlantic they are on."
Blykalla is developing a passively safe, highly compact 55 MWe lead-cooled fast reactor (known as SEALER) based on more than 25 years of research. Blykalla is currently raising its A2 round, which Oklo will co-lead. Oklo is developing its sodium-cooled fast-reactor powerhouses of up to 75 MWe, with a focus on deployment at U.S. sites to serve industrial, defense, and data-center customers.
By linking efforts across the U.S. and Europe, Oklo and Blykalla are demonstrating how advanced reactor developers can align on fuel, supply chains, and regulation to accelerate commercialization globally. The partnership reflects a shared commitment to making advanced reactors a cornerstone of the clean energy transition, delivering reliable power for industry, data centers, and future electrification needs.
Oklo's strategy has led to both international and domestic partnerships across the technological and regulatory landscape, including agreements with Siemens, Korea Hydro & Nuclear Power, Liberty Energy, and ABB, aimed at ensuring best-in-class turbines, controls, and grid integration.
About Oklo Inc .: Oklo Inc. is developing fast fission power plants to deliver clean, reliable, and affordable energy at scale, establishing a domestic supply chain for critical radioisotopes, and advancing nuclear fuel recycling to convert nuclear waste into clean energy. Oklo was the first to receive a site use permit from the U.S. Department of Energy for a commercial advanced fission plant, was awarded fuel from Idaho National Laboratory, and submitted the first custom combined license application for an advanced reactor to the U.S. Nuclear Regulatory Commission. Oklo is also developing advanced fuel recycling technologies in collaboration with the U.S. Department of Energy and U.S. National Laboratories.
About Blykalla
Blykalla is the Swedish developer of advanced SMRs, commercializing lead-cooled fast reactors for industrial use.
