Oklo invests $5 million in Swedish nuclear firm Blykalla to accelerate advanced reactor commercialization

U.S. nuclear technology company Oklo Inc. (NYSE: OKLO) has announced a strategic partnership with Swedish firm Blykalla AB, investing approximately $5 million to co-lead Blykalla's next investment round. This collaboration aims to accelerate the commercialization of advanced nuclear reactors by focusing on technology collaboration, supply-chain coordination, and regulatory knowledge-sharing .

Under the 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. The partnership is designed to reduce costs and schedule risks, and it is one of the first transatlantic collaborations in the advanced nuclear reactor sector .

Oklo's CEO, Jacob DeWitte, stated, "This partnership strengthens the growing advanced reactor ecosystem in the face of unprecedented global demand for power. 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." Blykalla's CEO, Jacob Stedman, added, "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" .

Oklo is developing sodium-cooled fast-reactor powerhouses of up to 75 MWe, focusing on deployment at U.S. sites to serve industrial, defense, and data-center customers. Blykalla, on the other hand, is developing a passively safe, highly compact 55 MWe lead-cooled fast reactor (known as SEALER) based on over 25 years of research .

This strategic partnership underscores the potential of advanced nuclear reactors to contribute to the global clean energy transition. 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 .
