Oklo Inc. (NYSE: OKLO) and Swedish nuclear technology company Blykalla AB announced an expansion of their strategic partnership focused on fast reactor commercialization. The collaboration involves Blykalla's planned investment of $100-200 million and commitment of 30-40 engineers to U.S. operations, subject to final planning and approvals.

The expanded partnership includes two primary workstreams. Blykalla will support technical aspects of Oklo's U.S. Department of Energy-authorized reactor pilot project, including neutronics and thermohydraulics analyses. The companies will also explore fast-neutron irradiation testing opportunities using Oklo's facilities to support Blykalla's advanced reactor development.

"This partnership is about building new reactors more quickly by working together," said Jacob DeWitte, co-founder and CEO of Oklo. "Working with our Transatlantic partners can shorten critical pathways so we can bring more power plants on line more quickly."

Blykalla CEO Jacob Stedman noted that both companies share "an industrial, execution-driven approach" and expressed enthusiasm for building deployment pathways that could reduce risk and accelerate timelines.

Blykalla raised $50 million in capital last year to advance its lead-cooled reactor technology called SEALER. The Swedish company is developing the 55 MWe reactor for hyperscalers and energy-intensive industries in U.S. and European markets.

All collaboration activities will comply with applicable laws and regulations, including export control requirements and safeguards obligations, and operate within established DOE and U.S. government program frameworks, according to the companies' statement.

Oklo received the first site use permit from the U.S. Department of Energy for a commercial advanced fission plant and submitted the first custom combined license application for an advanced reactor to the U.S. Nuclear Regulatory Commission.
