Oklo, Blykalla to Expand Strategic Partnership Through U.S. Investment and Collaboration

SANTA CLARA, Calif. & STOCKHOLM--(BUSINESS WIRE)-- Oklo Inc. (NYSE: OKLO) (“Oklo”) and Blykalla AB (“Blykalla”), advanced nuclear technology companies from the U.S. and Sweden respectively, today announced an expansion of their transatlantic strategic partnership to broaden collaboration on fast reactor commercialization.

Blykalla—which last year raised $50 million in capital to accelerate the industrialization and commercialization of its advanced lead-cooled reactor, the SEALER—aims to deploy capital and engineering resources in the U.S. through this collaboration. Resources include planned investments and expected personnel commitments on the scale of $100-200 million and 30-40 engineers across relevant workstreams, subject to final planning and approvals.

“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 and Oklo share an industrial, execution-driven approach,” said Jacob Stedman, CEO of Blykalla. “We’re excited to build deployment pathways that can reduce risk and accelerate timelines.”

Under the expanded partnership, Oklo and Blykalla expect to pursue workstreams that may include the following:

• Reactor pilot project: Blykalla will support, where appropriate, select technical workstreams relevant to Oklo’s U.S. Department of Energy (DOE)–authorized reactor pilot project, such as neutronics and thermohydraulics analyses. This collaboration will help Oklo accelerate its technology development, while enabling Blykalla to advance its reactor deployment capabilities.
• Fast-neutron irradiation testing: The companies will explore opportunities to support fast-neutron irradiation testing using Oklo’s powerhouses to generate insights for Blykalla’s advanced reactor development.

All collaboration will be conducted in compliance with applicable laws and regulations, including export control requirements and safeguards obligations, and within established DOE and U.S. government program frameworks.

About Oklo Inc.: Oklo Inc. is developing fast fission power plants to deliver clean, reliable, affordable energy at global scale; establishing a domestic supply chain for critical radioisotopes; and advancing nuclear fuel recycling to convert used nuclear fuel into clean energy. Oklo was the first to receive a site use permit from the U.S. Department of Energy for a commercial advanced fission plant, was awarded fuel from Idaho National Laboratory, and submitted the first custom combined license application for an advanced reactor to the U.S. Nuclear Regulatory Commission. Oklo is also developing advanced fuel recycling technologies in collaboration with the U.S. Department of Energy and U.S. National Laboratories.

About Blykalla: Blykalla is a Swedish developer of next-generation nuclear power, commercializing its advanced lead-cooled reactor, SEALER, for the US and European markets. Designed for hyperscalers and energy-intensive industries, the 55 MWe SEALER provides high-density, dispatchable power for on-site deployment.

Building on over 25 years of research, Blykalla has overcome historical material challenges in lead-cooled reactors through patented aluminum-alloyed steels that form a self-healing protective layer, enabling long-term commercial deployment. Backed by partners including Oklo, Uniper, and ABB, Blykalla aims to become a reliable, carbon-free power provider for the global AI and industrial economy.
