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 USA and Sweden. Through increased cooperation and coordination, both developers aim to reduce costs and schedule risks.
Together the companies will examine shared suppliers for reactor-agnostic equipment to improve availability, schedules, and cost. Under the agreement, 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.
The agreement includes Oklo co-leading Blykalla’s next investment round through a commitment of about USD5 million.
The partners said the agreement demonstrates how advanced reactor developers can align on fuel, supply chains, and regulation to accelerate commercialisation globally. “The partnership reflects a shared commitment to making advanced reactors a cornerstone of the clean energy transition, delivering reliable power for industry, data centres, and future electrification needs,” they said.
Blykalla is a spin-off from the KTH Royal Institute of Technology in Stockholm, where lead-cooled reactor systems have been under development since 1996. The company – founded in 2013 as a joint stock company – is developing the 55 MWe SEALER (Swedish Advanced Lead Reactor) lead-cooled SMR.
Oklo is developing its sodium-cooled fast-reactor Aurora powerhouses of up to 75 MWe, with a focus on deployment at US sites to serve industrial, defence, and data centre customers.
“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 recognising that we have more to gain from cooperating than from competing.”
Blykalla CEO Jacob Stedman added: “Oklo and Blykalla share a practical, industrial approach to bringing advanced fission to market. 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.”
