Deep Isolation Nuclear, Inc. announced the launch of its multi-year, full-scale, at-depth deep borehole demonstration program (the "Demonstration Program"), in collaboration with the Deep Borehole Demonstration Center ("DBDC"), Halliburton, Amentum, NAC International, and Occlusion Nuclear Solutions, to conduct testing of its deep borehole technology for safely and permanently disposing of nuclear waste. Deep Isolation, in collaboration with Halliburton and the DBDC, hosted a Groundbreaking Event to officially launch the Demonstration Program on January 28, 2026. The event, held at the Deep borehole Demonstration Center facility, located at the Halliburton Drilling Technology Facility near Cameron, Texas, brought together project partners and key stakeholders from across the nuclear industry, the U.S. Department of Energy, and officials from the State of Texas, Milam County, and City of Cameron.
The Groundbreaking Event marked the beginning of this critical demonstration project, which is aimed at buildingholder and regulatory confidence in the Company's deep borehole disposal technology. The Demonstration Program, which does not utilize radioactive material, will provide crucial data and operational experience to further the commercialization strategy for Deep Isolation's deep borehole disposal technology". Deep Isolation's nuclear waste disposal technology is being designed to leverage directional drilling to isolate spent nuclear fuel and high-level radioactive waste in deep boreholes located underground in suitable rock formulations.
Deep Isolation believes that directional borehole disposal could provide robust and deep isolation for many types of radioactive waste, provide flexibility in repository siting, as well as allow for modular implementation adaptable to specific waste management programs and inventories. Deep Isolation's Universal Canister System will be utilized in the Demonstration Program, has been extensively tested, and is engineered to contain various types of spent fuel and high-level radioactive Waste from legacy and advanced reactors for long-term storage, transportation, and disposal.
