Low-Level Radioactive Waste Management and Disposition: A Workshop

Workshop
October 24, 2016 - October 25, 2016

Location: Keck Center of the National Academies
500 Fifth St. NW Washington DC 20001

The Department of Energy's Office of Environmental Management (DOE-EM) is responsible for the cleanup of the sites used by the federal government for nuclear weapons development and nuclear energy research. DOE-EM cleanup involves retrieval, treatment, storage, transportation, and disposition of hundreds of different radioactive and hazardous solid and liquid wastes. Low-level radioactive waste--defined by exclusion: waste that does not meet the statutory definitions for spent nuclear fuel, high-level radioactive waste, or transuranic waste--is physically and chemically diverse, ranging from lightly contaminated soils and building materials to highly irradiated nuclear reactor components. It is the most volumetrically significant waste stream (millions of cubic meters) being generated by the cleanup program.

This workshop considered similarities between successful case studies, in which unique disposition pathways have been developed to address low-level radioactive wastes, and explored ways to extend these similar characteristics to problematic waste -- low-level wastes currently without a clear disposition pathway. Specifically, the workshop explored:

-- the key physical, chemical, and radiological characteristics of low-level radioactive waste that govern its safe and secure management (i.e., packaging, transport, storage) and disposition, in aggregate and for individual waste-streams, and

-- how key characteristics of low-level waste are incorporated into standards, orders, and regulations that govern the management and disposition of low-level radioactive waste in the United States and in other major waste-producing countries.

Low-level Radioactive Waste Management and Disposition: Proceedings of a Workshop (2017)

The Department of Energy's Office of Environmental Management (DOE) is responsible for the safe cleanup of sites used for nuclear weapons development and government-sponsored nuclear energy research. Low-level radioactive waste is the most volumetrically significant waste stream generated by the DOE cleanup program, and it is also generated through commercial activities such as nuclear power plant operations and medical treatments.
