Title: Waste Package Degradation process Model Report

Abstract

A crucial element of the long-term postclosure safety strategy for the potential monitored geologic repository at Yucca Mountain is to contain high-level radioactive waste (HLW), and to keep that waste and its container as dry as possible. There are several degradation processes that could impact the performance of the engineered barrier system (EBS). The role of this PMR is to describe one of the process-level models (Waste Package Degradation) utilized to evaluate these degradation processes. To evaluate the postclosure performance of the monitored geologic repository proposed for construction at Yucca Mountain, a Total System Performance Assessment (TSPA) will be conducted. A set of nine Process Model Reports (PMRs), of which this document is one, is being developed to summarize the technical basis for process-level models supporting the TSPA model. These reports cover the following areas: Integrated Site Model; Unsaturated Zone Flow and Transport; Near-Field Environment (NFE); EBS Degradation, Flow, and Transport; Waste Package Degradation; Waste Form Degradation; Saturated Zone Flow and Transport; Biosphere; and Disruptive Events. These PMRs are supported by several Analysis and Model Reports (AMRs) that contain more detailed technical information. This technical information consists of data, analyses, models, software, and other documentation necessary to defend the applicabilitymore » of each model for its intended purpose. The PMR is intended to ensure the traceability of waste package degradation information from its various sources through the AMRs, PMRs, and eventually in TSPA.« less
