- Abstract:
- While the United States (US) has facilities that can and do dispose of most low-level nuclear waste (LLW), it does not yet have a viable disposal pathway for two categories of waste: so-called greater-than-class-c (GTCC) nuclear waste, and nuclear waste with characteristics similar to it, or “GTCC-like.” These two categories essentially straddle the United States’ LLW inventory, for which disposal facilities are in operation, and high-level nuclear waste (HLW) inventory, for which no disposal capability exists. GTCC nuclear waste is produced by multiple sources: commercial nuclear power plants, medical procedures, industrial and research activities, and Department of Energy (DOE) missions, including those related to national security and the cleanup of legacy facilities. These activities carry with them an ethical responsibility to dispose of the nuclear waste they generate rather than pass it on to the next generation. Security task forces have also identified the lack of a disposal pathway for sealed sources of GTCC nuclear waste as a concern, given the potential for its theft and use in a dispersal device. This report, part of a series of publications on nuclear waste policy at the Center on Global Energy Policy, Columbia University SIPA, explores the history of DOE, Nuclear Regulatory Commission (NRC), and state efforts to develop disposal capabilities for GTCC and GTCC-like inventories. It explains why this gap merits greater attention from policymakers now and identifies measures Congress, the DOE, and the NRC could take, should they decide to address it. US government efforts to develop disposal capabilities for GTCC waste date back to 1985 when Congress made it a federal responsibility. For a time, disposal in the planned repository at Yucca Mountain, Nevada, was contemplated. But in the absence of appropriations to move that project forward since 2010, the federal government recently issued planning documents that identify generic commercial LLW disposal facilities and the Waste Isolation Pilot Plant (WIPP) deep geologic repository in New Mexico as preferred alternatives. Of the commercial LLW disposal facilities in operation, only the WCS facility in Texas has expressed interest in the GTCC disposal mission. The political climate for GTCC disposal in both New Mexico and Texas has darkened in recent years, though, casting doubt on the federal government’s plans. If the US government decides to prioritize the goal of establishing disposal capability for GTCC and GTCC-like nuclear waste, Congress, the DOE, and the NRC could take the following steps to help realize it in the near term.
