Used nuclear fuel and high-level radioactive wastes are by-products of nuclear energy production and other applications of nuclear technology, and the consensus approach to disposing of those wastes safely is to encapsulate them and emplace them in stable geologic formations (geologic repositories) where they will be isolated from people and the environment for very long periods of time. The federal government has established environmental standards for waste isolation that any proposed geologic repository must meet.
In July 2021, the American Nuclear Society established a special committee to consider possibilities for revised generic environmental standards for disposal of spent nuclear fuel and high-level radioactive waste in the United States. The committee developed a number of recommendations, which are contained in a draft report that was to be issued in February for review and comment by stakeholders. The draft report can be found on the ANS website, at ans.org/policy/repositorystandard/.
The committee’s draft recommendations are based on two underlying assumptions. First, that the relevant legislative framework for regulation defined in the Nuclear Waste Policy Act (NWPA) remains unchanged. Specifically, it is assumed that the Environmental Protection Agency will be charged with promulgating environmental standards for disposal and that the Nuclear Regulatory Commission will be charged with reviewing applications for disposal facilities using licensing requirements and criteria consistent with the EPA standards. Second, that existing generic disposal standards will be updated or replaced.

Two large tanks near the Effluent Treatment Facility (ETF) at the Department of Energy’s Hanford Site in Washington state were removed recently to make way for future wastewater treatment activities at the ETF.

The Defense Waste Processing Facility (DWPF) at the Department of Energy’s Savannah River Site (SRS) in South Carolina has resumed operations after a completing a processing improvement that the DOE said will enable safer operations and more efficient vitrification of radioactive waste.

A federal appeals court rejected a lawsuit brought by environmental groups challenging the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility (CISF) for spent nuclear fuel in Andrews County, Texas. The U.S. Court of Appeals for the D.C. Circuit found that the NRC reasonably applied its hearing regulations when approving Interim Storage Partners’ (ISP) license for the facility.
The ICP buried waste retrieval team successfully completed targeted TRU waste retrieval at the INL Site. The effort spanned 17 years and resulted in the exhumation of more than 10,000 cubic meters of buried TRU waste from 5.69 acres of the site’s Subsurface Disposal Area. (Photo: DOE)
The Department of Energy recently honored eight teams from its Office of Environmental Management (EM) with Secretary of Energy 2022 Achievement Awards. The awards recognized projects at the DOE’s Idaho, Savannah River, and Hanford sites, as well as a group of employees that revamped and expanded DOE-EM’s Minority Serving Institutions Partnership Program (MSIPP-EM). In addition, DOE-EM employees on crosscutting departmental teams received awards.
The awards were part of the DOE’s annual Honor Awards, the agency’s highest form of employee recognition for excellence and achievement.

The Department of Energy is asking for feedback on a new report analyzing potential options for preparing high-level radioactive waste for vitrification at the department’s Hanford Site near Richland, Wash. Vitrification is the process of treating radioactive waste by immobilizing it in glass.
The report, Waste Treatment and Immobilization Plant High-Level Waste Treatment: Analysis of Alternatives, was commissioned in response to a 2018 determination by the U.S. Army Corps of Engineers that it was unlikely the DOE would meet its mandated deadlines for treating Hanford’s tank waste.
