US nuclear waste disposal company Deep Isolation says that a two-year research project that subjected its Universal Canister System to the kinds of conditions found thousands of feet below the surface has shown materials used in its fabrication perform reliably and remain resistant to corrosion over time.

Deep Isolation Nuclear, an innovator in nuclear waste disposal technology, on January 13 said the company has successfully completed its Project SAVANT (Sequential Advancement of Technology for Deep Borehole Disposal), a two-year research initiative funded by the U.S. Department of Energy Advanced Research Projects Agency–Energy (ARPA-E). The project found that Deep Isolation’s Universal Canister System (UCS) and borehole casing materials can sufficiently resist corrosion to safely store nuclear waste material, further validating the design and advancing the company toward a full-scale deep borehole disposal demonstration.

As the energy industry looks to step up co-location of data centers and power sources, a company developing a new nuclear waste disposal technology is hoping to do the same thing.

Following its establishment in April 2025, the NEA project on Waste Integration for Small and Advanced Reactor Designs (WISARD) held its first technical workshop in Washington, DC, on 4-6 November 2025. The workshop was hosted by the Nuclear Energy Institute (NEI), one of the WISARD signatory organisations, and included an open session dedicated to discussions with the NEI Advanced Nuclear Forum (ANF).

The ARPA‑E‑funded project involved testing a universal canister for advanced reactor used fuel and high‑level waste in multiple repository types.

Deep Isolation said Wednesday it has completed a three-year-long Department of Energy-funded project that advances the company’s Universal Canister System technology for nuclear waste disposal.

Project UPWARDS has culminated in the manufacture, physical testing and validation of a disposal-ready Universal Canister System for used nuclear fuel and high-level radioactive waste from advanced reactors.

Nuclear waste disposal technology company Deep Isolation Nuclear has announced the completion of a three-year project to manufacture, physically test, and validate a disposal-ready universal canister system (UCS) for spent nuclear fuel and high-level radioactive waste from advanced reactors.

Nuclear power is back, largely due to the skyrocketing demand for electricity, including big tech’s hundreds of artificial intelligence data centers across the country and the reshoring of manufacturing. But it returns with an old and still-unsolved problem: storing all of the radioactive waste created as a byproduct of nuclear power generation.
