The acquisition brings CEI’s specialized capabilities in liquid-metal systems, component development, fabrication, manufacturing, and applied R&D into Oklo’s expanding team, strengthening technical areas directly relevant to sodium handling, thermal systems, and Oklo’s sodium-cooled, Aurora powerhouse technology.

Founded in 1996, CEI has decades of experience working with sodium, sodium-potassium alloy (NaK), and lithium systems, including legacy cleanup and decommissioning-related work connected to landmark nuclear sodium programs such as the Fast Flux Test Facility, Fermi 1, and the Experimental Breeder Reactor II. CEI and Oklo have worked together for multiple years on sodium-related equipment and capabilities, including sodium loop work, flow meters, pumps, and sodium safety training.

Oklo’s Aurora powerhouse is a sodium-cooled fast reactor designed to use liquid-metal cooling, passive safety characteristics, and natural circulation to support decay heat removal after shutdown, making sodium systems expertise directly relevant to Oklo’s planned deployment pathway.

The acquisition advances Oklo’s development and deployment strategy by bringing a specialized technical partner in-house to facilitate critical-path sodium-related work for Oklo’s Aurora powerhouse deployment. CEI’s expertise is expected to support faster design iteration, improve access to specialized sodium-handling expertise, and reduce execution risk associated with specialized equipment, fabrication, testing, and training.

CEI brings a highly specialized team of around 20 engineers, fabricators, and welders with deep experience in sodium and other alkali-metal systems to Oklo’s expanding technical and manufacturing organization. The acquisition adds a free cash flow positive business while strengthening Oklo’s ability to internalize critical engineering, fabrication, testing, and R&D capabilities that support Aurora powerhouse commercialization.

In addition to supporting Oklo's programs, CEI plans to maintain its longstanding commercial relationships across the nuclear sector, by continuing to provide specialized sodium technology, manufacturing, and engineering services.
