WASTE ACCEPTANCE DECISIONS AND UNCERTAINTY ANALYSISAT THE OAK RIDGE ENVIRONMENTAL MANAGEMENT WASTE MANAGEMENT FACILITY

摘要

The Waste Acceptance Criteria (WAC) Attainment Team (AT) routinely provides the U.S. Department ofEnergy (DOE) Oak Ridge Operations with Go/No-Go decisions associated with the disposition of over 1.8million yd 3 of low-level radioactive, TSCA, and RCRA hazardous waste. This supply of waste comes from60+ environmental restoration projects over the next 15 years planned to be dispositioned at the Oak RidgeEnvironmental Management Waste Management Facility (EMWMF).The EMWMF WAC AT decision making process is accomplished in four ways: (1) ensure a clearly definedmission and timeframe for accomplishment is established, (2) provide an effective organization structure withtrained personnel, (3) have in place a set of waste acceptance decisions and Data Quality Objectives (DQO) forwhich quantitative measures are required, and (4) use validated risk-based forecasting, decision support, andmodeling/simulation tools.We provide a summary of WAC AT structure and performance. We offer suggestions based on lessons learnedfor effective transfer to other DOE.
