Oklo completes successful end-to-end demonstration of fuel recycling process

Oklo announced the successful completion of the first end-to-end demonstration of the key stages of its advanced fuel recycling process, in collaboration with Argonne National Laboratory and Idaho National Laboratory. This achievement marks a significant step forward in Oklo‘s efforts to scale up its fuel recycling capabilities and deploy a commercial-scale recycling facility to increase advanced reactor fuel supplies, and enhance fuel cost effectiveness. Supported by a $5M cost-share award from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy under the Optimizing Nuclear Waste and Advanced Reactor Disposal Systems Program , this project aims to facilitate the deployment of a commercial-scale advanced fuel recycling facility. “We know that recycling is an important path to reduce high-level waste, and advance nuclear energy with safe and sustainable domestic fuel stocks,” said ARPA-E Director Evelyn N. Wang. “Through ARPA-E’s ONWARDS Program, Oklo is working to achieve these goals. This milestone marks an important step forward in the team’s progress as they work towards economically viable nuclear fuel recycling.” Oklo’s fuel recycling technology is engineered to extract over 90% of the remaining potential energy from used fuel, which is expected to be utilized in Oklo powerhouses to generate clean energy. It incorporates unique proliferation-resistant features, including maintaining the consolidation of transuranic materials.
