Siemens Energy is a supplier of steam turbine and generator technology - rotating equipment that is part of the conventional island in small and large nuclear generation plants. Siemens Energy will supply the power conversion and supporting systems, fostering efficiencies through economies of scale. Standardizing equipment across Oklo’s powerhouses is expected to result in cost savings in manufacturing, construction, operations, and maintenance. Utilizing shared spare parts across deployment is expected to reduce maintenance downtime, enhance reliability, and improve overall performance.

“We prioritize cost in our engineering process to fully leverage the advantages of fast fission technology,” said Jacob DeWitte, Oklo’s co-founder and CEO. “Our technology is based on proven designs, allowing us to utilize small, pre-fabricated, and non-pressurized components made from readily available materials and existing supply chains, further reducing costs and complexity.” Oklo’s fast fission technology utilizes liquid metal as a coolant. Liquid metal’s high boiling point allows the reactor to operate at high temperatures without being pressurized. This design enables the use of commonly available alloys, benefiting from existing large-scale supply chains already producing nearly identical parts.
