Annual Summary of the Integrated Disposal Facility Performance Assessment 2008
- Hanford Site (HNF), Richland, WA (United States)
The U.S. Department of Energy (DOE) order on radioactive waste management (DOE 1 999a) as well as the Maintenance Plan for the Hanford Immobilized Low-Activity Tank Waste Performance Assessment (Mann 2004) require an annual summary on the adequacy of the Hanford Immobilized Low-Activity Tank Waste Performance Assessment (RLAW PA) in each year in which a performance assessment is not issued. The most recent approved PA is the Hanford Immobilized Low-Activity Waste Performance Assessment: 2001 Version (Mann et al 2001). The RLAW PA evaluated the adequacy of the ILAW disposal facility, now referred to as the Integrated Disposal Facility (IDF), to safely dispose vitrified Hanford Site tank waste. More recently, a preliminary evaluation for the disposal of offsite low-level and mixed low-level waste was considered in the Integrated Disposal Facility Risk Assessment (Mann et al. 2003a). The first phase of IDF construction was completed on April 28, 2006 and included the installation of the cell liners and leachate collection tanks. The IDF is now in a preoperational maintenance mode and will not receive treated tank waste for several years. In view of these circumstances, the RCRA Part B Permit for the Integrated Disposal Facility has been modified to recognize that the facility will not be receiving waste in the near future. A subsequent modification indicated transfer of the IiDF from the DOE Office of River Protection (DOE/ORP) operation to the DOE Richland Operations Field Office (DOE/RL). This summary is the latest in a succession of sumnmaries that have been published since 2000 (Mann, 2000b, 2002, 2003b, 2004, 2005, 2006 and 2007) and approved by the Field Manager, Office of River Protection (e.g., Schepens 2005c). This annual summary compares new data collected during Fiscal Year 2008 with the Hanford Immobilized Low-Activity Waste Performance Assessment: 2001 Version (Mann et al 2001), which has been approved by DOE (DOE 2003a). Most of the data collected during Fiscal Year 2008 pertained to long-term contaminant release from ILAW packages made at the Waste Treatment Plant. Results of data collection and additional analyses do not change the conclusions of the 2001 ILAW PA as they pertain to RLAW disposal.
