Abstract

Part of the effort of the Seismic Safety Margins Research Program (SSMRP) has been directed at generating a fragility data base for equipment used in control and safety systems in commercial nuclear power plants. Component fragility data have been compiled in various forms, depending on their content, intended use, and level of reduction. The data are stored in a relational data base on the LLNL CDC 7600 computers; this provides easy accessibility for LLNL computer users. This report describes the present structure of the data base and presents its contents through the use of tables. This report is a revision of an earlier one of the same name and numbers (NUREG/CR-2680) and (UCRL-53038). Additional data have been included and the presentation has been revised to enhance its usability.
