【 摘 要 】

As part of the current Saltstone Disposal Facility (SDF) Performance Assessment (PA) revision, Mechanically Stabilized Earth (MSE) vault closure cap degradation mechanisms and their impact upon filtration through the MSE vault closure cap were evaluated for the base case land use scenario (i.e. institutional control to pine forest). The degradation mechanisms evaluated included pine forest succession, erosion, and colloidal clay migration (Phifer 2003). Infiltration through the upper hydraulic barrier layer of the closure cap as determined by this evaluation will be utilized as the infiltration input to subsequent PORFLOW vadose zone contaminant transport modeling, which will also be performed as part of the PA revision.
