08:38 AM EDT, 03/30/2026 (MT Newswires) -- Oklo ( OKLO ) and Blykalla said Monday that they expanded their transatlantic partnership to accelerate the commercialization of fast nuclear reactors.

Sweden-based Blykalla said it plans to deploy $100 million to $200 million in capital and commit 30-40 engineers to support US workstreams, subject to approvals. The collaboration will focus on advancing reactor deployment and shortening development timelines, they said.

Blykalla will support technical work linked to Oklo's ( OKLO ) pilot reactor project authorized by the US Department of Energy, including neutronics and thermohydraulics analysis, they added.

The companies said they also plan to explore fast-neutron irradiation testing using Oklo's ( OKLO ) powerhouses to support Blykalla's lead-cooled SEALER reactor development.
