Dounreay Site Restoration Ltd. (DSRL) and the Robotics and Artificial Intelligence in Nuclear (RAIN) Hub, a consortium of universities led by the University of Manchester, are working together on the development of robots capable of accessing areas that are inaccessible or unsafe for humans to work in. The robots will be used to inspect and characterize Dounreay’s laboratories, buildings, and structures as the United Kingdom prepares to decontaminate and decommission the nuclear site.

The Nuclear Regulatory Commission has approved the transfer of the operating license of the shutdown Kewaunee nuclear power plant from Dominion Energy to EnergySolutions. The transfer, which includes the general license for the Wisconsin site’s spent fuel storage facility, is contingent upon approval by the Wisconsin Public Service Commission.

EnergySolutions entered into an agreement with Dominion in May 2021 to acquire the Kewaunee site for decommissioning.

Depending on the size and complexity of a decommissioning project, the transportation and disposal of radioactive waste will have an oversized impact on planning, schedule, and budget. The scope of decommissioning a site contaminated with radioactive material begins and ends with the proper and safe packaging of waste and subsequent transportation from the site to the final disposal location. Once all of the waste is gone from the site, the compliance exercise can be completed and the site released from controls (i.e., the radioactive materials license is terminated and the site is decommissioned).

Idaho Gov. Brad Little, attorney general Lawrence Wasden, Idaho legislators, county and city representatives, and the Department of Energy’s cleanup program management staff gathered at the Idaho National Laboratory site on March 30 to mark the completion of a cleanup project that helps protect the Snake River Plain Aquifer and fulfills a commitment with the State of Idaho.

Utah-based EnergySolutions is joining Radiation Safety and Control Services (RSCS) in the decommissioning of NS Savannah, the world’s first nuclear-powered merchant ship, currently berthed at the Port of Baltimore in Maryland. EnergySolutions announced on March 29 that a joint venture of the two companies, Nuclear Ship Support Services, is conducting the final phases of decommissioning the ship’s reactor, which was defueled in 1975 but remains in place.

Holtec International and Hyundai Engineering & Construction have signed an agreement to cooperate in the area of nuclear plant decontamination and decommissioning.

Under the teaming agreement, Hyundai E&C will participate in D&D activities at Holtec-owned decommissioning sites in the United States to build its capabilities and experience in preparation for decommissioning projects in South Korea, which will be undertaken by the two companies. The agreement also provides for the two companies to further expand their cooperation internationally.

The remediation of two former Soviet-era uranium mining sites in Kyrgyzstan has been completed on schedule and below budget, despite difficulties caused by the COVID-19 pandemic, the European Bank for Reconstruction and Development (EBRD) announced on March 28.

Last fall, scientists from Sandia, Los Alamos, and Lawrence Berkeley national laboratories began the third phase of a years-long experiment to understand how salt and very salty water behave near hot nuclear waste containers in a salt-bed repository. Initiated in 2017, the Brine Availability Test in Salt (BATS) project is part of a spent nuclear fuel research campaign within the Department of Energy’s Office of Nuclear Energy (DOE-NE).

The Department of Energy recently awarded $24.7 million to Oak Ridge cleanup contractor UCOR for its work at the Oak Ridge site in Tennessee from April 2021 through October 2021, amounting to 98 percent of the available fee for the evaluation period.

Several antinuclear groups are challenging the Nuclear Regulatory Commission’s licensing of Interim Storage Partners’ (ISP) consolidated interim storage facility for spent nuclear fuel in Andrews, Texas, by filing briefs in the U.S. Court of Appeals for the District of Columbia Circuit on March 18. The groups appealing the license include Beyond Nuclear, Don’t Waste Michigan (a coalition of seven environmental groups), and Sierra Club.

The NRC granted ISP a license in September 2021, authorizing the company to receive, possess, transfer, and store up to 5,000 metric tons of spent fuel and 231.3 metric tons of greater-than-Class C radioactive waste for 40 years. ISP plans to expand the facility in seven additional phases, up to a total capacity of 40,000 metric tons of fuel.

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.

Without a plan for addressing issues in completing construction projects at the Waste Isolation Pilot Plant in New Mexico, the Department of Energy cannot ensure that further cost increases and schedule delays will not continue, according to a report by the Government Accountability Office. In particular, the GAO said, the DOE has not developed a corrective action plan to address root causes identified for the rising cost and the delay in building a new ventilation system at the transuranic waste repository.

Westinghouse Electric Company and nuclear waste management company Perma-Fix Environmental Services plan to jointly develop a state-of-the-art advanced materials treatment facility in the United Kingdom. During the 2022 Waste Management Symposia, held last week in Phoenix, Ariz., the two companies signed a nonbinding agreement to cooperate on a facility that will provide low-level radioactive waste treatment services to the European market.

The Department of Energy’s Office of Environmental Management (EM) has issued EM Strategic Vision 2022-2032, a blueprint for planned nuclear-related cleanup efforts over the next decade. The document outlines environmental cleanup priorities for 2022–2032, focusing on safety, innovation, and improved performance.

According to a March 8 statement, the DOE is working to fulfill “the moral and ecological responsibility of safely dealing with contamination and delivering on environmental justice goals in communities that were vital to the development of nuclear weapons and advances in government-sponsored nuclear energy research.”

EM Strategic Vision 2022–2032, which is available here, is an update of previous iterations and was developed with feedback from regulators, tribal nations, local communities, and other partners.

Preparations are being made to enclose, or “cocoon,” the K East Reactor, the seventh of nine former reactors at the Department of Energy’s Hanford Site. The cocooning project is expected to be completed by the end of the year.

The organization of the commercial fuel cycle with the geographical separation of waste disposal facilities from other nuclear facilities is a historical artifact. There are large economic and institutional incentives to collocate many fuel cycle facilities with the repository. Similarly, there are large economic and institutional incentives to collocate proposed fission battery factories and nuclear hydrogen/synthetic fuel (synfuel) gigafactories with other waste management facilities (used fuel storage, low-level waste disposal, etc.) to create nuclear technology hubs that create economic savings, generate jobs and tax revenue, and simplify waste management.

The Nuclear Regulatory Commission published its proposed decommissioning rule in the March 3 Federal Register, opening a 75-day public comment period. Approved by the NRC in November 2021, the proposed rule would incorporate lessons learned from plants that have recently transitioned to decontamination and decommissioning and improve the effectiveness and efficiency of the regulatory framework.

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.

Canadian Nuclear Laboratories (CNL) is asking its stakeholders (members of the public, industry, elected officials, and employees) to support a proposal to construct the Near Surface Disposal Facility (NSDF) to dispose of legacy radioactive waste at the Chalk River Laboratories in Ontario.

Isotek, the Department of Energy contractor responsible for overseeing the inventory of uranium-233 at Oak Ridge National Laboratory and preparing it for removal from the site, said it plans to resume preparations for processing high-dose U-233 in March. The company was forced to suspend its operational readiness review of the Initial Processing Campaign at Oak Ridge in January due to issues related to COVID-19, as well as difficulties operating in colder temperatures.
