This volume is the fourth in a sequence of reports that document the December 1991 preliminary comparison with 40 CFR 191, Subpart B (the Standard; US EPA, 1985) for the Waste Isolation Pilot Plant (WIPP). The three previous volumes describe the background of the project, the performance-assessment methodology, and the 1991 results (Volume 1); the probability and consequence models used in the calculations (Volume 2); and the reference data base (Volume 3). This volume contains the results of uncertainty and sensitivity analyses conducted using the methodology, modeling system, and data described in the earlier volumes. These analysis provide quantitative and qualitative insights on the relationships between uncertainty in the models and data used in the WIPP performance assessment and the resultant uncertainty in the results of the performance assessment. Uncertainty and sensitivity analysis is an important part of the WIPP performance assessment and contributes to the overall analysis in the following areas: (1) assessment of uncertainty in performance-assessment results that must be used in comparison regulatory standards, (2) identification of modeling areas where reductions in uncertainty can significantly improve the confidence that can be a placed in performance-assessment results, and (3) verification that the models used within the performance-assessment process are operating properly.
