The Department of Energy has increased the funding level for its community engagement on consent-based siting funding opportunity announcement (FOA) from $16 million to $26 million. The DOE first announced it was making funding available to communities interested in learning more about consent-based siting, management of spent nuclear fuel, and interim storage facility siting considerations last September. The FOA follows the DOE’s recent update to its consent-based process for siting an interim storage facility for SNF.

Another calendar year has passed. Before heading too far into 2023, let’s look back at what happened in 2022 for the American Nuclear Society and the nuclear community. In today's post that follows, we have compiled from Nuclear News and Nuclear Newswire what we feel are the top nuclear news stories from September through December 2022.

Advanced reactors and small modular reactors with strikingly different coolants and sizes offer an array of different benefits, but when it comes to fuel cycle issues, including spent fuel and waste, they have a lot in common with conventional light water reactors. Two reports released within the last week—a National Academies of Sciences, Engineering, and Medicine (NASEM) consensus committee report two years in the making and a Department of Energy study released by Argonne National Laboratory—address the timely topic of advanced reactor fuel cycle issues. While the NASEM committee ventured to define research and infrastructure needs to support the entire nuclear power fuel cycle, inclusive of new technologies, for decades to come, the DOE report compares the front- and back-end fuel cycle metrics of three reactor designs (from NuScale Power, TerraPower, and X-energy) that have been selected for DOE cost-share–funded demonstrations within this decade. Together, these reports provide assurance that the fuel cycle needs of a fleet of new reactors can be met and point to near-term research and planning needs.

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.

The Department of Energy has announced that it will make $16 million in funding available to communities interested in learning more about “consent-based siting, management of spent nuclear fuel, and interim storage facility siting considerations.” The funding opportunity follows the DOE’s recent update to its consent-based process for siting an interim storage facility for SNF.

Holtec International announced that its flagship HI-STORM Multi-Purpose Canister (MPC) spent fuel storage technology was selected by Spain’s national company Enresa for a fleet of six nuclear power reactors at four plant sites in the country. Equipos Nucleares S.A. (ENSA), a Cantabria-based manufacturer of equipment for the Spanish nuclear fleet, was named a consortium partner with Holtec in the order, which was conducted under European Union procurement rules.

The Department of Energy’s Office Nuclear Energy (NE) has published a new report summarizing and analyzing public feedback on the department’s proposed consent-based siting process for the consolidated interim storage of the nation’s spent nuclear fuel.

Nagra, Switzerland’s national cooperative for the disposal of radioactive waste, has announced that it has selected Nördlich Lägern as the site for a deep geological repository for radioactive waste. According to Nagra, extensive investigations have shown that Nördlich Lägern, located in northern Switzerland near the German border, is the most suitable area for a geologic repository with the best overall safety reserves.

The Nuclear Waste Technical Review Board (NWTRB) announced it will hold a public meeting on September 13–14 to review information on Department of Energy research and development activities related to the geologic disposal of spent nuclear fuel and high-level radioactive waste in clay-bearing host rocks and R&D on clay-based engineered barriers. The hybrid (in-person/virtual) meeting will begin on both days at 12:00 p.m. EDT and is scheduled to adjourn at approximately 5:00 p.m. EDT.

The NWTRB is an independent federal agency that provides ongoing, objective evaluation of the technical and scientific validity of activities undertaken by the DOE related to implementing the Nuclear Waste Police Act.

Canada’s Nuclear Waste Management Organization (NWMO) is shifting the timing for selecting a preferred site for a spent nuclear fuel repository to the fall of 2024, a full year later than previously planned. The NWMO, a nonprofit organization tasked with the safe, long-term management of Canada’s spent fuel in a deep geological repository, said the delay is the result of several provincial lockdowns associated with the COVID-19 pandemic.

The Department of Energy’s Office of Environmental Management (EM) has approved a new plan that will accelerate the disposition of spent nuclear fuel at its Savannah River Site in South Carolina by more than 20 years, which will result in a savings of more than $4 billion.

Under the newly approved approach, called accelerated basin de-inventory (ABD), SRS will dissolve spent fuel at the site’s H Canyon chemical separations facility and send it through the liquid waste program to be vitrified and stored on-site until a federal repository is identified.

Researchers at three Canadian universities are studying whether bentonite clay—used as an engineered barrier in Canada’s proposed deep geological repository—can support sulfide-producing microbes that can eat away at the canisters containing spent nuclear fuel.

Canada’s Nuclear Waste Management Organization (NWMO) has announced that it has successfully completed a full-scale demonstration of the engineered barriers that are designed to contain and isolate Canada’s spent nuclear fuel in a deep geological repository.

“The momentum toward a new era of nuclear energy is predicated in part on government and industry claims that new technological solutions to nuclear waste are forthcoming. But challenges remain in their realization at the necessary scale,” writes freelance journalist Jenny Johnson in the article “Nuclear renaissance hinges on solving the waste issue."

The last spent nuclear fuel elements from Idaho National Laboratory’s Advanced Test Reactor (ATR) have been retrieved from a water-filled storage basin and transferred to a nearby dry-storage facility in accordance with a 1995 agreement with the State of Idaho, the Department of Energy’s Office of Environmental Management (EM) announced this week.

The government of Sweden announced on January 27 that it has issued a permit to the Swedish Nuclear Fuel and Waste Management Company (SKB) to build a deep geological repository for spent nuclear fuel at Forsmark in the municipality of Östhammar. The government also issued a permit to construct a spent fuel encapsulation plant in Oskarshamn, where the country’s inventory of spent fuel is currently being stored.

The Nuclear Waste Technical Review Board, an independent federal agency established by Congress to conduct ongoing technical and scientific evaluation of the Department of Energy’s efforts to manage and dispose of spent nuclear fuel and high-level radioactive waste, will hold virtual public meetings on March 1 and March 2, to review recent DOE activities.

Foratom, the Brussels-based trade association for the European nuclear industry, wrote a letter yesterday to the European Commission welcoming the EC’s recent proposal to include nuclear in the EU taxonomy (under certain conditions), but also offering some suggestions for the proposal’s improvement.

The taxonomy is the European Union’s classification system for directing investments toward environmentally sustainable economic projects. On December 31, the EC’s nuclear-inclusive proposal was sent to expert panels from EU member states, with a response deadline of today. At a news briefing yesterday, however, an EC spokesperson announced an extended deadline of January 21.

The Department of Energy has restarted its consent-based siting process for identifying sites to store the nation’s spent nuclear fuel. Yesterday, the DOE issued a request for information that “will be used to further develop DOE’s consent-based siting process and overall waste management strategy in an equitable way.”
