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.
Quality assurance procedures for computer software supporting performance assessments of the Waste Isolation Pilot Plant. [Contains glossary]
TL;DR: In this article, the quality assurance (QA) philosophy and procedures for software used by the Performance Assessment Division of the Nuclear Waste Technology Department (NWTD) of Sandia National Laboratories, which directly supports the Waste Isolation Pilot Plant (WIPP), are presented.
Quality assurance procedures for analyses and report reviews supporting performance assessments of the Waste Isolation Pilot Plant
TL;DR: In this article, the authors present the quality assurance philosophy and procedures for analyses and report reviews used by the Performance Assessment Department of Sandia National Laboratories, which directly supports the Waste Isolation Pilot Plant (WIPP).
