The DOE and a contractor recently succeeded in disposing of Oak Ridge’s low-activity U-233, but not before recovering Th-229 from the material.

This past October, the Department of Energy’s Oak Ridge Office of Environmental Management (OREM) and its contractor Isotek successfully completed processing and disposing the low-dose inventory of uranium-233 stored at Oak Ridge National Laboratory (ORNL), ending a two-year effort that has eliminated a portion of the site’s legacy nuclear material and provided rare nuclear isotopes for next-generation cancer treatment research.

The ANS Fuel Cycle and Waste Management Division will present a webinar today at noon EST (the recording will be available via the webinar archive to all ANS members) featuring an international panel of experts on nuclear waste reprocessing. The panel will explore the idea of separating certain radionuclides from waste using recycling technology that enables pure materials to be used for other purposes.

California-based Oklo has received a $2 million cost-share award from the Department of Energy for the commercialization of advanced fuel recycling capabilities by using electrorefining technology. Oklo is matching $1 million in funds and is partnering with the DOE and Argonne National Laboratory on this public-private partnership, which is intended to help reduce fuel costs for advanced reactor designs while reducing waste by turning used fuel into advanced reactor fuel.

The Department of Energy has announced up to $40 million in funding for a new Advanced Research Projects Agency-Energy (ARPA-E) program to conduct research and development into technologies for reprocessing and ultimately disposing of used nuclear fuel. The program, “Optimizing Nuclear Waste and Advanced Reactor Disposal Systems” (ONWARDS), announced on May 19, targets both open (once-through) and closed (reprocessing) fuel cycles to reduce the amount of waste produced from advanced reactors tenfold when compared to light water reactors.
