Waste isolation pilot plant (WIPP) shaft seal system performance sensitivity and design impact

摘要

This analysis quantifies the robustness in the current Waste Isolation Pilot Plant (WIPP) shaft sealing system design.In the WIPP Compliance Certification Application (CCA), the shaft seal was shown to be highly effective in limiting brine imgration into and out of the repository.The analysis uses a coupled systems model of the site,engineered barriers,and waste to evaluate the sensitivity of sealing system performance to variations in seal material properties and to identify factors that may impact future designs.
