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.
