Oklo completes end-to-end demonstration of advanced fuel recycling
Oklo Inc. has announced that it has completed the first end-to-end demonstration of its advanced fuel recycling process as part of an ongoing $5 million project in collaboration with Argonne and Idaho National Laboratories. Oklo’s goal: scaling up its fuel recycling capabilities to deploy a commercial-scale recycling facility that would increase advanced reactor fuel supplies and enhance fuel cost effectiveness for its planned sodium fast reactors.

To reduce the defective coating fraction of TRISO-coated UO2 particles, failure mechanisms of fuel particle coating during the coating processes have been studied. Examinations of the coated fuel particles at every coating stage revealed two kinds of silicon carbide (SiC)-defective particles. The SiC-defective particles with partly carbonized kernels were formed by chemical reactions during SiC deposition when the coating layer of inner dense pyrolytic carbon was defective. The SiC-defective particles with nonreacted kernels were formed by mechanical shocks during unloading of SiC-coated particles from the coater. The coating processes were improved by controlling particle fluidization modes in the coater and by adopting a coating process without unloading and loading of the particles at intermediate coating stages.
