Generic seismic ruggedness of power plant equipment: Final report
This report presents the results of a program with the overall objective of demonstrating the generic seismic adequacy of as much nuclear power plant equipment as possible by means of collecting and evaluating existing seismic qualification test data. These data are then used to construct ''ruggedness'' spectra below which equipment in operating plants designed to earlier earthquake criteria would be generically qualified. The report gives the methodology for the collection and evaluation of data which are used to construct a Generic Equipment Ruggedness Spectrum (GERS) for each equipment class considered. Associated with each GERS are inclusion rules, cautions, and checklists for field screening of in-place equipment for GERS applicability. The collected data is available as a computerized Electric Power Research Institute data base accessible to utilities. A GERS provides a measure of equipment seismic resistance based on available test data. As such, a GERS may also be used to judge the seismic adequacy of new or replacement equipment or to estimate the seismic margin of equipment reevaluated with respect to earthquake levels greater than considered in the original design. Twenty-five equipment classes have been considered to date, resulting in nineteen finalized GERS.
