TL;DR: In this article, uncertainty and sensitivity analysis results obtained in the 1992 performance assessment (PA) for the Waste Isolation Pilot Plant (WIPP) are presented, where the primary performance measure under study is the complementary cumulative distribution function (CCDF) used in assessing compliance with the U.S. Environmental Protection Agency's (EPA's) standard for the geologic disposal of radioactive waste.

TL;DR: The most appropriate conceptual model for performance assessment (PA) at the waste isolation pilot plant (WIPP) is believed to include gas generation resulting from corrosion and microbial action in the repository, and a dual-porosity (matrix and fracture porosity) representation for the solute transport in the Culebra dolomite member of the Rustler formation as mentioned in this paper.

TL;DR: The conceptual and computational structure of a performance assessment (PA) for the Waste Isolation Pilot Plant (WIPP) is described, with the result that the WIPP will be the first operational facility in the United States for the geologic disposal of radioactive waste.

TL;DR: Procedures used in recent performance assessments for the WIPP to translate regulations into a structure that facilitates quantitative analysis are described.

TL;DR: Sandia National Laboratories (SNL) is evaluating long-term performance against criteria in Subpart B of the Environmental Radiation Protection Standards for Management and Disposal of Spent Nuclear Fuel, High-Level and Transuranic Radioactive Wastes (40 CFR Part 191, US EPA, 1985) as discussed by the authors.
