Title: RIP Input Tables From WAPDEG for LA Design Selection: Repository Horizon Elevation- 2- Leel AML 50% and Near Maximum

Abstract

The purpose of this calculation is to document the WAPDEG version 3.09 (CRWMS M&O 1998b). Software Routine Report for WAPDEG (Version 3.09) simulations used to analyze waste package degradation and failure under the repository exposure conditions characterized by a two-tier thermal loading repository design. Also documented is the post-processing of these results into tables of waste-package-degradation-time histories suitable for use as input into the Integrated Probabilistic Simulator for Environmental Systems (RIP) version 5.19.01 (Golder Associates 1998) computer program. Specifically, the WAPDEG simulations discussed in this calculation correspond to waste package emplacement conditions (repository environment and design) as defined in the Total System Performance Assessment-Viability Assessment (CRWMS M&O 1998a).
