Nuclear power generation surpassed coal generation in the United States for the first time in 2020. As utilities continue to retire coal-fired plants, reusing the shuttered sites to host nuclear reactors could help the nation reach the goal of net-zero emissions by 2050 and prove economically beneficial both for nuclear deployments and for the communities impacted by fossil fuel generation. That’s according to a Department of Energy report released this week, detailing how hundreds of U.S. coal power plant sites that have recently retired or plan to close within the decade could be suitable for new nuclear power plants. Nuclear power’s high capacity factors mean those plants could deliver an added benefit—delivering more baseload power to the grid from the nameplate capacity replacement.

Those who welcomed the $700 million earmarked for high-assay low-enriched uranium (HALEU) supply in the Inflation Reduction Act of 2022 (IRA) in August have cause to celebrate again. The White House sent a supplemental appropriation request to Congress on September 2 that would provide more than double the IRA funds if passed—$1.5 billion—for the Department of Energy’s Office of Nuclear Energy to build a reliable supply of both low-enriched uranium for existing U.S. nuclear power plants and HALEU for the advanced reactors that will be built within the decade.

The Versatile Test Reactor, a custom-designed sodium-cooled fast neutron spectrum test reactor, is one step closer to its goal of providing data to accelerate research, development, and demonstration of diverse advanced reactor designs. The Department of Energy released the Final Versatile Test Reactor Environmental Impact Statement (Final VTR EIS) on May 13, and 30 days after its anticipated May 20 publication in the Federal Register, the DOE will issue a Record of Decision on the project.

The Department of Energy has announced the steps that would-be applicants must take to access funds from the $6 billion Civil Nuclear Credit (CNC) Program. Guidance published April 19 invites owners or operators of those plants most at risk of near-term closure to apply during the program’s first award cycle. With shutdown planned next month, Entergy’s Palisades plant would top that list (read on for more on Michigan’s efforts to keep the plant operating), but any reactor with publicly announced plans to close by September 30, 2026, that meets other program criteria could be certified for credits. Successful applicants won’t have to wait long for good news: the DOE plans to announce award decisions as soon as 30 days after the May 19 deadline for submitting certification applications together with sealed bids for credits.

The Department of Energy’s Office Nuclear Energy has launched a $6 billion program aimed at preserving the existing U.S. fleet of nuclear power reactors. Established under the Bipartisan Infrastructure Law, the Civil Nuclear Credit Program will allow owners and operators of commercial nuclear power reactors at economic risk of shutting down to apply for credits via a sealed bid process.

The Department of Energy has issued a request for proposals for the fabrication and testing of a prototype eight-axle railcar to carry the nation’s spent nuclear fuel and high-level radioactive waste. The heavy-duty, flat-deck railcar design known as “Fortis” received approval from the Association of American Railroads (AAR) in January 2021 to proceed to building and testing.

Congress needs to take action to break the impasse over a permanent solution for commercial spent nuclear fuel, according to a report by the U.S. Government Accountability Office. The GAO recommends that Congress amend the Nuclear Waste Policy Act (NWPA) to authorize a new consent-based siting process, restructure the Nuclear Waste Fund, and direct the Department of Energy to develop and implement an integrated waste management strategy.
The GAO also recommends that the DOE finalize the consent-based process it began in 2015 for siting consolidated interim storage and permanent geologic repository facilities. The DOE agrees with that recommendation.

Several lead test rods of Westinghouse’s EnCore accident tolerant fuel recently arrived at Oak Ridge National Laboratory for post-irradiation examination over the next year in support of the Nuclear Regulatory Commission’s licensing process. The rods were installed in 2019 in Exelon’s Byron-2, a 1,158-MWe pressurized water reactor, and were removed in fall 2020 and prepared for shipment to ORNL.

Kathryn Huff, the Department of Energy’s acting assistant secretary for nuclear energy, asserted in an article published online by the Office of Nuclear Energy (DOE-NE) on July 30 that demonstration reactors, such as the Natrium and Xe-100 reactors being built as full-size power producers with cost-shared funding from the DOE, and test reactors, such as the Versatile Test Reactor, are both necessary for nuclear innovation. Both are also line items in the DOE budget request, and Huff’s article sends a clear message to appropriators about the need to fund both the Advanced Reactor Demonstration Program (ARDP) and the VTR.
