Oklo Inc. is developing fast-fission power plants, advanced nuclear-fuel recycling and fabrication capabilities, and critical-radioisotope businesses. Its Aurora technology uses liquid-metal-cooled, metal-fuelled fast reactors designed for passive, self-stabilizing operation and potential use of recycled fuel.
