Oklo partners with Sweden’s Blykalla
After making waves last week at Idaho National Laboratory by breaking ground on its first Aurora Powerhouse reactor, Oklo has again made headlines this week by partnering with Stockholm, Sweden–based advanced reactor developer Blykalla.
More details: The nature of the companies’ new partnership comes in two significant parts. First, under a joint technology development agreement, Oklo and Blykalla will collaborate on and knowledge-share in the areas of materials, components, nonnuclear supply chain sourcing, fuel fabrication, and licensing.
Oklo has further emphasized supply chain development as a focus for the companies, saying that it will “examine shared suppliers for reactor-agnostic equipment to improve availability, schedules, and cost.”
In more direct supply chain support, Oklo also said it may directly provide Blykalla with select, as yet unidentified components.
In addition to these plans, the companies said they will jointly pursue new targeted research and development and regulatory analysis to increase reliability and decrease cost without changing reactor designs.
The second prong of this partnership comes in the form of funding. Oklo has committed approximately $5 million to colead Blykalla’s A2 funding round, which is currently underway.
While Oklo highlighted this as “one of the first transatlantic partnerships in the advanced nuclear reactor sector,” it notably comes on the heels of many other transatlantic partnerships recently made between U.S. and U.K. nuclear companies.
Reactor details: Oklo’s flagship reactor is the Aurora Powerhouse, a 75-MWe sodium–cooled, metal-fueled fast reactor that builds on the design and operating heritage of the Experimental Breeder Reactor-II.
Blykalla is currently developing SEALER, a 55-MWe lead-cooled fast reactor. In February, the company broke ground on its reactor testing site at the Oskarshamn nuclear power plant.
Swedish nuclear: Sweden’s first nuclear power plant entered commercial operation in 1975 with the now-decommissioned 615-MWe Barsebaeck-1. The country is home to six operational power reactors: one at Oskarshamn, two at Ringhals, and three at Forsmark.
Bloomberg recently reported that Sweden has moved to recall its ban on uranium mining as early as January 1, 2026. This move has been taken as a sign that the country is working to reduce its reliance on fuel imports as momentum and enthusiasm around a renewed nuclear industry grow.
Last week, the Government Offices of Sweden announced that Sweden’s minister for energy, business and industry will cohost an international summit on new nuclear energy in the Baltic region in October with Finland’s minister of climate and environment.
