Deep Isolation Validates Deep Borehole Technology for Nuclear Waste Disposal with DOE Funding

Deep Isolation Nuclear Inc has confirmed through federally funded research that deep borehole disposal is a viable method for high-level radioactive waste from advanced reactor fuel recycling. The company received part of a USD36 million grant under the DOE's ARPA-E ONWARDS programme. A project involving Oklo Inc and national laboratories aims to commercialize a fuel recycling facility compatible with deep borehole repositories. Analysis indicates that waste streams from the electrorefining process align with deep borehole disposal standards, potentially facilitating the closure of the metal fuel cycle.
