A new report from the environmental advocacy group RePlanet makes the case for recycling used nuclear fuel for use in advanced power reactors. According to the report, What a Waste: How fast-fission power can provide clean energy from nuclear waste, by using current inventories of used fuel and depleted uranium stocks in Europe and the United Kingdom, fast breeder reactors could generate between 600 and 1,000 years of carbon-free electricity for the entire European Union.

Oklo said it has submitted a licensing project plan to the Nuclear Regulatory Commission, outlining the company’s plans for preapplication engagement activities that support the future licensing of a used nuclear fuel recycling facility. The first-of-a-kind facility is intended to produce fuel to support the deployment of Oklo’s advanced fission power plants.

In a former farm field just outside the historic town of Janesville in south-central Wisconsin, a large concrete-and-steel building is taking shape. Dubbed the Chrysalis, the building will eventually house eight accelerator-based neutron generators, which start-up company SHINE Technologies will use to produce molybdenum-99. As the precursor to the medical radioisotope technetium-99m, Mo-99 is used in tens of millions of diagnostic procedures every year, primarily as a radioactive tracer.

At the heart of the Chrysalis will be the high-flux neutron generators, being supplied by SHINE’s sister company, Phoenix. The compact accelerators use a deuterium-tritium fusion process to produce neutrons, which in turn induce a subcritical fission reaction in an aqueous low-enriched uranium target (19.75 percent uranium-235) to produce Mo-99.

Duncan

Rep. Jeff Duncan (R., S.C.), a member of the House Energy and Commerce Committee, has issued a three-page “Blueprint for Nuclear Innovation and Competitiveness,” highlighting nuclear policy priorities in the areas of licensing and regulatory modernization, financing, and fuel (including used fuel). According to a press release from Duncan’s office, the document aims “to help chart the course for the nuclear energy agenda in the next Congress and facilitate policy discussions among both lawmakers and industry leaders.” Published last week—along with a related “Dear Colleague” letter—the blueprint is also, according to E&E News, “a sign of his ambitions for landing a more senior role with the committee,” including a subcommittee leadership position should the GOP gain control of the House in the next Congress.

The Department of Energy is providing $38 million in funding for a dozen projects aimed at developing technologies to advance spent nuclear fuel reprocessing, reduce the volume of high-level waste requiring permanent disposal, and provide domestic advanced reactor fuel stocks. The projects are being led by universities, private companies, and national laboratories.

The Gateway for Accelerated Innovation in Nuclear (GAIN) announced the three recipients of its fourth and final round of 2022 vouchers on October 10. The vouchers were awarded to Curio Solutions, which is developing a spent fuel recycling process, and to two companies that are separately investigating advanced reactor siting—Elementl Power and the Tennessee Valley Authority (TVA). The funds for each award will go directly to Oak Ridge National Laboratory.

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 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.

Graham

Menendez

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.

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.

Citing costs and a lack of industry interest, the Nuclear Regulatory Commission is discontinuing its rulemaking for the reprocessing of spent nuclear fuel. The rulemaking would have amended the NRC’s regulations, adding a new regulatory framework for licensing commercial reprocessing facilities.

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.

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.

Piercy

Nesbit

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.
