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.

DOE funds R&D for advanced reactor fuel cycle management

March 14, 2022, 7:01AMNuclear News

The Department of Energy's Advanced Research Projects Agency–Energy (ARPA-E) has awarded a total of $36 million for 11 projects to develop technologies that will limit the amount of waste produced from advanced reactors and will support sustainable domestic fuel stocks. The projects include research into the facilities and systems required to reprocess, recycle, and dispose of spent fuel generated through diverse advanced reactor fuel cycles.

U.S. lawmakers back regional fuel bank for Middle Eastern nations

Sens. Bob Menendez (D., N.J.), chairman of the Senate Foreign Relations Committee, and Lindsey Graham (R., S.C.) have introduced a resolution calling for the U.S. government to adopt a policy that would permit any Middle Eastern state access to nuclear fuel via a regional fuel bank, provided it agrees to abstain from uranium enrichment and reprocessing.

Modeled on the International Atomic Energy Agency’s nuclear fuel bank in Kazakhstan, the proposed regional fuel bank would allow the commercial development of nuclear power throughout the Middle East while at the same time eliminating the need for dangerous and destabilizing domestic nuclear programs, according to a February 11 press release from the legislators.

ANS Grand Challenge: Closing the nuclear fuel cycle

It seems like only yesterday that former ANS President Andy Klein announced the nine ANS Nuclear Grand Challenges that need to be addressed to ensure that existing and emerging nuclear technologies benefit current and future generations. The Fuel Cycle and Waste Management Division (FCWMD) immediately began tackling the grand challenge of closing the nuclear fuel cycle by sponsoring recurring panel sessions on the topic at subsequent ANS meetings.

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.

Oklo awarded $2 million to commercialize advanced fuel recycling

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.

DOE announces funding for advanced reactor fuel cycle and reprocessing R&D

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.

Metal frameworks could capture krypton-85 during reprocessing

According to a story published by the Massachusetts Institute of Technology on July 24, the capture of gaseous fission products such as krypton-85 during the reprocessing of spent nuclear fuel could be aided by the adsorption of gasses into an advanced type of soft crystalline material, metal organic frameworks(MOF), which feature high porosity and large internal surface areas that can trap an array of organic and inorganic compounds.

ANS backs NRC rulemaking on spent fuel reprocessing

ANS Executive Director/CEO Craig Piercy sent a letter to the Nuclear Regulatory Commission on May 28 urging the agency to resume work on a proposed rulemaking to allow spent fuel reprocessing in the United States. As the letter explains, “the lack of an efficient, technically robust, and technology-inclusive regulatory foundation for reprocessing and recycling is a barrier to innovation.”

Steve Nesbit, who was recently elected ANS’s next vice president/president-elect, chairs the ANS Nuclear Waste Policy Task Force and helped develop the letter. ANS News staff talked with Nesbit about the development and goals of ANS’s participation in the NRC’s rulemaking process.
