When the Department of Energy’s Advanced Research Projects Agency–Energy launched the Optimizing Nuclear Waste and Advanced Reactor Disposal Systems (ONWARDS) program in 2022, it posed a challenge that the nuclear industry had never seriously confronted before: how to design waste management solutions that anticipate the coming shift to advanced reactors and not merely retrofit existing systems built for an older generation of technology. The program’s objectives were ambitious—reduce disposal footprint, enable scalable pathways for unfamiliar waste streams, and build the technical foundations for future disposal—yet also tightly grounded in the realities of emerging nuclear fuel cycles. For the nuclear community, this was a timely call. Advanced reactors were accelerating toward deployment, but the waste management systems needed to support them had not kept pace.

Nuclear waste technology company Deep Isolation Nuclear has launched a multiyear demonstration program of its deep borehole technology for disposing of nuclear waste. The full-scale, at-depth deep borehole demonstration program is being done in collaboration with Halliburton, Amentum, NAC International, and Occlusion Nuclear Solutions, along with the Deep Borehole Demonstration Center (DBDC).

Deep Isolation announced this week that it has received funding from the Department of Energy to test a range of deep borehole disposal canisters at a test facility in Cameron, Texas, managed by the nonprofit Deep Borehole Demonstration Center.
