Risk and Decisions About Disposition of Transuranic and High-Level Radioactive Waste

This report addresses how DOE should incorporate risk into decisions about whether the nation should use alternatives to deep geologic disposal for some of these wastes. It recommends using an exemption process involving risk assessment for determining how to dispose of problematic wastes. The report outlines criteria for risk assessment and key elements of a risk-informed approach. The report also describes the types of wastes that are candidates for alternative disposition paths, potential alternatives to deep geologic disposal for disposition of low-hazard waste, and whether these alternatives are compatible with current regulations.
