Recycling used nuclear fuel helps shrink the physical and environmental demands on permanent underground storage sites by drastically lowering the volume of waste destined for disposal. According to the authors of the newly released report, this approach transforms materials currently viewed as hazardous refuse into a supplemental energy source, making the management of the remaining waste more politically and technically manageable.
The report highlights that “recycling this UNF is possible with advanced recycling technologies and should substantially reduce the amount of high-level waste requiring permanent disposal, thereby reducing repository footprint and costs.” The researchers further explain that a “closed fuel cycle that combines multi-recycling with fast reactors reduces the volume of HLW requiring DGR disposal by 95%.”
Essentially, instead of burying all the radioactive leftovers from nuclear power plants in massive, expensive underground vaults, recycling allows engineers to filter out the components that can still be used to create power. By extracting these useful elements to feed newer types of reactors, the amount of material that actually needs to be buried forever is cut down to a small fraction of its original size. This process makes it easier to find and build storage locations because they would not need to be nearly as large or as numerous to handle the nation’s energy waste.
The report “The Case for Commercial Recycling of Used Nuclear Fuel: Assessment and Recommendations” was published by the Energy Innovation Reform Project in Fairfax, Virginia, in April 2026. It was prepared by a team of experts including Dr. Christina Leggett, Paul J. Saunders, and Samuel Thernstrom.
