Book Description
This paper details the development of a decontamination approach for the West Valley Demonstration Project (WVDP), Decontamination Project Plan (Plan). The WVDP is operated by West Valley Nuclear Services Company (WVNSCO), a subsidiary of Westinghouse Government and Environmental Services, and its parent companies Washington Group International and British Nuclear Fuels Limited (BNFL). The WVDP is a waste management effort being conducted by the United States Department of Energy (DOE) at the site of the only commercial nuclear fuel reprocessing facility to have operated in the United States. This facility is part of the Western New York Nuclear Service Center (WNYNSC), which is owned by the New York State Energy Research and Development Authority (NYSERDA). As authorized by Congress in 1980 through the West Valley Demonstration Project Act (WVDP Act, Public Law 96-368), the DOE's primary mission at the WVDP is to solidify high-level liquid nuclear waste safely; transport the high-level waste (HLW) to a federal repository; and decontaminate and decommission the facilities and hardware used to solidify the HLW and conduct the WVDP. This includes a provision for the disposal of low-level waste (LLW) and transuranic waste (TRU) produced during processing of the HLW. Continuation of the effort to reduce the hazard and risk associated with historic operations to the extent needed to ensure the health and safety of the public and the environment will see a change in focus from stabilization of liquid HLW to stabilization of former plutonium and uranium extraction (PUREX) reprocessing plant facilities. This will be achieved through the activities of in-cell component removal and packaging, and preparation for long-term disposal of the long- lived radionuclides. These radionuclides are associated with the former PUREX facility operations, including, and upstream from, facilities utilized in the primary separation and first plutonium/uranium split cycles. The closure strategy for the WVDP is subject to ongoing evaluation and decision-making involving DOE and NYSERDA. Implementation will be subject to a future Record of Decision (ROD) and an Environmental Impact Statement (EIS).

Book Description
The primary mission of the West Valley Demonstration Project (WVDP) is to solidify a large volume of high-level liquid waste (2.3 million liters -- 600,000 gallons) produced during reprocessing plant operations and stored in underground tanks. This is to be accomplished through the maximum use of existing facilities. This required a significant effort to remove existing equipment and to decontaminate areas for installation of liquid and cement processing systems in a safe environment while maintaining exposure to workers as low as reasonably achievable. The reprocessing plant occupied a building of about 33,000 m2 (350,000 ft2). When the WVDP was initiated, approximately 6 percent of the plant area was in a non-contaminated condition where personnel could function without protective clothing or radiological controls. From 1982 to 1988, an additional 64 percent of the plant was cleaned up and much of this converted to low- and high-level waste processing areas. The high-level liquid and resulting low-level liquids are now being treated in these areas using an Integrated Radwaste Treatment System (IRTS). The Project has now focused attention on installation, qualification and operation of a vitrification system which will convert the remaining high-level waste into borosilicate glass logs. The stabilized waste will be sent to a Federal Repository for long-term storage. From 1982 to 1988, about 70 technical reports were dealing with specific tasks and cleanup efforts. This report provides an overview of the decontamination and decommissioning work done in that period. The report emphasizes lessons learned during that effort. Significant advances were made in: remote and contact decontamination technology; personnel protection and training; planning and procedures; and radiological controls. 62 refs., 35 figs., 5 tabs.
