Use of performance assessments to generate a repository Q list
Items identified and classified as important to safety are placed on the repository Q list. The Q list identifies structures, systems, and components that are subject to quality assurance (QA) requirements beyond standard engineering practices as specified by 10CFR60, Part G. These QA requirements correspond to those imposed by 10CFR50, Appendix B, for safety class systems in nuclear power plants. These QA measures are applied to the repository design, procurement, and construction activities and operations to provide a higher degree of assurance that Q-list items will perform their intended functions. The QA measures are implemented by the direct incorporation of the requirements into appropriate design documents, such as drawings, specifications, and operational procedures. An assessment to identify items important to safety was completed for the proposed Yucca Mountain repository. The assessment implemented a classification methodology based on general guidance developed by the U.S. Department of Energy (DOE) for use by all repository projects. Although some qualitative judgment techniques were used, the assessment was based on quantitative dose and frequency performance assessments. This paper discusses the results of applying a performance assessment to generate the initial Yucca Mountain repository Q list.
