Description

  • Content Description: The Closure Plan for the E-Area low-level waste facility assumes that dynamic compaction performed at the end of the 100-year institutional control period will adequately stabilize all waste in Slit Trenches. However, some non-crushable waste containers with significant void space will not be stabilized by dynamic compaction. These non-crushable containers will gradually corrode, eventually collapse and cause the final closure cap to subside resulting in an increase of the infiltration rates. After subsidence occurs, the waste zone will be significantly reduced to concentrate waste in the lower portion of the slit trench, therefore increasing waste concentration. The trench subsidence may have an adverse impact on the 1000-year compliance specified in DOE Order 435.1. This study addresses the issue of trench subsidence, evaluates the resulting concentrations at the hypothetical 100-m well against those obtained based on the PA approach, and provides the maximum number of trenches that can subside without causing the well concentrations to be out of compliance.
