[en] The US Department of Energy (DOE) Office of Geologic Repositories (OGR) has provided general guidance to project offices for formulating a quality control list (Q-list). A Q-list is a list of structures, systems, components, and related activities subjected to 10 CFR Part 70 Subpart G ''Quality Assurance'' requirements. The OGR guidance requires the application of probabilistic risk assessment (PRA) techniques, including a master logic diagram and event trees. A Salt Repository Project (SRP) Q-List Working Group was established to implement the risk assessment techniques. The working group is composed of individuals of diverse backgrounds including repository design, PRA, consequence analysis, and licensing. It includes representatives from the Office of Nuclear Waste Isolation, Battelle Columbus Division, Fluor Technology, Inc., and Morrison-Knudsen Engineers. The work was initiated in October 1986 and completed within six months. This report presents the analyses done during this period. Results of the analyses were provided as input to the Site Characterization Plan Conceptual Design Report (SCP-CDR). This work also confirms parallel exploratory shaft facility analyses regarding the ''important to safety'' requirements specified by 10 CFR Part 60. 30 refs., 20 figs., 26 tabs
