Integrated Low-Level Radioactive Waste Disposal

Official abstract: The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its regulations that govern the land disposal of low-level radioactive waste to expand regulatory coverage to include certain transuranic wastes. The rule also introduces a new risk-informed framework for low-level waste disposal in which sites can develop waste acceptance criteria based on site-specific characteristics rather than using prescriptive limits. The proposed rule would allow for a graded approach: facilities that do not plan to accept significant quantities of long-lived radionuclides or Greater-Than-Class C waste will only need to meet a streamlined set of requirements, while those managing these waste streams must conduct technical assessments to ensure long- term safety. The proposed rule would also introduce new options for disposal of higher concentrations of waste, providing new alternatives for safe low-level waste management. These innovations support public health and environmental protection, as well as safe disposal of low- level radioactive waste, encourage operational efficiency, and offer greater flexibility for both current and future disposal facilities. In addition, the NRC is issuing draft implementing guidance for public comment.
