Strategic Collaboration
SANTA CLARA, Calif. / STOCKHOLM, Sweden – September 29, 2025 – U.S. advanced nuclear company Oklo Inc. (NYSE: OKLO) and Sweden’s Blykalla AB have announced a strategic partnership focused on technology collaboration, supply-chain coordination, and regulatory knowledge-sharing. As part of the agreement, Oklo will co-lead Blykalla’s next investment round with an approximately $5 million commitment, strengthening the companies’ joint effort to speed advanced nuclear deployment.
Joint Technology Development
Under a Joint Technology Development Agreement, the two fast-reactor developers will share insights on materials, components, non-nuclear supply chain sourcing, and licensing best practices across the United States and Sweden. The goal is to reduce costs and schedule risks, demonstrating how advanced nuclear companies can align on fuel, supply chains, and regulation to accelerate global commercialization.
Supply-Chain and R&D Goals
Oklo and Blykalla will examine shared suppliers for reactor-agnostic equipment to improve availability, schedules, and costs. Oklo may also supply select components for Blykalla’s direct use, supporting a vertically integrated, potentially cross-border supply chain. In parallel, the companies will pursue targeted R&D and regulatory analysis to boost reliability and lower lifecycle costs without requiring design changes.
Executive Perspectives
“This partnership strengthens the growing advanced reactor ecosystem in the face of unprecedented global demand for power,” said Jacob DeWitte, Oklo co-founder and CEO. “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.”
“Oklo and Blykalla share a practical, industrial approach to bringing advanced fission to market,” said Jacob Stedman, Blykalla CEO. “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.”
Company Backgrounds
Blykalla is developing a passively safe, highly compact 55 MWe lead-cooled fast reactor (SEALER) based on more than 25 years of research, and is currently raising its A2 investment round, which Oklo will co-lead.
Oklo is developing sodium-cooled fast-reactor powerhouses of up to 75 MWe, targeting deployment at U.S. sites to serve industrial, defense, and data-center customers. Oklo’s focus on selling power, not plants, has led to international and domestic partnerships, including agreements with Siemens, Korea Hydro & Nuclear Power, Liberty Energy, and ABB to secure best-in-class turbines, controls, and grid integration.
Commitment to Clean Energy
By linking efforts across the U.S. and Europe, 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.
