Granholm

Secretary of energy Jennifer Granholm recently discussed the future of clean energy with Christopher M. Matthews, the U.S. energy editor for the Wall Street Journal. The May 15 live Q&A focused on Granholm’s perspective on the Biden administration’s policies for decarbonization and energy security. Granholm, who mentioned nuclear briefly at beginning of her remarks, returned to the issue at the end of the half-hour interview. In her answer to Matthews’s question, she addressed nuclear industry incentives, safety and waste concerns, next-generation technologies, and fusion.

Fossil fuels? Matthews opened the discussion by noting President Biden’s signing of the Inflation Reduction Act (IRA) last year, allocating “billions of dollars in tax credits and federal loans to boost green energy, including electric vehicles, hydrogen production, and more.” He added, “At the same time, the administration has called on oil and gas producers to increase drilling to slow inflation and to tamp down energy prices.”

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.

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.

It is often said that in Washington, “trust is the coin of the realm.” Of course, you can be forgiven for thinking these days that trust in politics is an outmoded concept—that the only coin of the realm today is, well, “coin.” But you would be wrong.

Behind the facade of political polarization and tribalism there still exists a genuine desire to make good policy. Of course, each side of the ideological spectrum will always have their preferred set of solutions, and those solutions will usually be “spiced” by the parties’ respective “bases.” But I never cease to be surprised by how much undetected common ground exists on practical matters.

During the last six months, in partnership with the bipartisan U.S. House Advanced Reactor Caucus, I have had the honor of moderating monthly Jeffersonian dinners on Capitol Hill with members of Congress and leaders from across the nuclear profession. If you are not familiar with the format, a Jeffersonian dinner requires that there be one single conversation at the table around a posed central question, such as, “Is nuclear energy overregulated?” or “Should the U.S. recycle its nuclear fuel?”

New Mexico State University is collaborating with TerraPower, Idaho National Laboratory, and Savannah River National Laboratory on a three-year project to develop a plan to recycle spent nuclear fuel. The project is being funded by an $8.5 million grant from the Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E), under the Optimizing Nuclear Waste and Advanced Reactor Disposal Systems (ONWARDS) program. ONWARDS is designed to increase the use of nuclear power as a reliable, clean energy source, as well to as limit the amount of waste generated by advanced nuclear reactors.

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.

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.

ANS will host the webinar “Creating Value from Waste: Recycling Valuable Isotopes & Surplus Energy” on Thursday, January 27, starting at noon EST.

The International Atomic Energy Agency has created a new program, NUclear TEChnology for Controlling Plastic Pollution (NUTEC Plastics), to address the global environmental impact of plastic pollution in oceans. It uses nuclear technology to monitor pollution and also to decrease the volume of plastic waste by using irradiation to complement traditional plastic recycling methods.
