Who we are CHBWV Team – 312 Employees and Subcontractors The CHBWV team is comprised of CH2M HILL, BWX Technologies, Inc. and Environmental Chemical Corporation (ECC). The project is conducted by the U.S. Department of Energy (DOE) in cooperation with the New York State Energy Research and Development Authority (NYSERDA). The West Valley Demonstration Project is an environmental cleanup and waste management project located about 35 miles south of Buffalo.

Background 1966-1972 – Spent fuel reprocessing resulted in 600,000 gallons of liquid high-level waste. Plant shut down for modifications; operations never resumed. 1962 – Nuclear Fuels Services constructed the first commercial nuclear fuel reprocessing plant in the United States at West Valley. 1980 – President Jimmy Carter signs the West Valley Demonstration Project Act. 1996-2002 – HLW vitrification is conducted at the WVDP, resulting in 275 canisters of vitrified HLW. 2011 – CH2M HILL BWXT West Valley was awarded WVDP Phase I Decommissioning Facility Disposition Contract for WVDP

Agency Responsibilities New York State Energy Research Development Authority (NYSERDA) owns the WVDP premises and the surrounding 3,345 acres Western New York Nuclear Service Center (WNYNSC) Includes the State-Licensed Disposal Area (SDA) and the Nuclear Regulatory Commission-Licensed Disposal Area (NDA) DOE manages 200 acre portion of WNYNSC under the WVDP Act Solidify High Level Waste (HLW) Develop containers for disposal of HLW Transport HLW to federal repository for disposal Dispose low-level waste and transuranic waste resulting from HLW solidification program Facility decontamination and decommissioning U.S. Nuclear Regulatory Commission (NRC) prescribed WVDP decommissioning criteria Consistent with decommissioning criteria under NRC’s license that is held in abeyance by NYSERDA
