Major Risk Factors Integrated Facility Disposition Project (IFDP) Oak Ridge, TN. External Technical Review (ETR) Report.

摘要

An External Technical Review (ETR) was conducted, at the request of EM-20 and with concurrence of DOE Oak Ridge Office (OR), in accordance with the 'External Technical Review Charter of Major Risk Factors in the Integrated Facility Disposition Project (IFDP) in Oak Ridge, TN,' dated June 2008. In developing this charter, OR proposed the major risk factors as: (1) Treatment and Disposal of large quantities of Mercury Contaminated Soil and Debris, and (2) Technical Approaches related to Facility Reconfiguration for Radioactive Waste and Low Level Liquid Waste Management. Further, OR submitted a request for Critical Decision (CD) 1 Approval for EM consideration, dated May 30, 2008. Approximately two million pounds of mercury are unaccounted for at Y-12, potentially resulting in contamination of soil and groundwater. The greatest risk/liability to DOE and the public is transport of mercury to the surface water (East Fork Poplar Creek), which flows off the federal reservation through private property to waters of the State of Tennessee, and its uptake by fish, plants, and other animal life. DOE, regulators, and the public need to have reasonable confidence in the technologies and technical approaches used to remediate this contamination in regards to safety, effectiveness, and environmental stewardship and sustainability.
