Abstract:

The Seismic Qualification Utilities Group (SQUG) was formed to explore the use of earthquake experience data of equipment performance to resolve Nuclear Regulatory Commission (NRC) initiated Unresolved Safety Issue (USI) A-46. The NRC staff endorses use of SQUG data for final resolution of A-46. The parameters used in the facility level testing behave differently in high level acceleration tests resulting in highly insignificant data. Their identification and proper data adjustment are important in fragility tests. The failure loads determined in failure analyses are significant in establishing fragility limits. The response for multiaxis excitation is highly dependent on the test configuration of the fragility testing. A study was conducted to correlate the seismic performance of typical power plant and industrial structures with their design criteria. Some components in a nuclear plant are not required for continued function. However, their failure may impair the safety features of other plant components. Such items should be termed as Seismic II/I and should be qualified to maintain structural integrity only. These topics are addressed in the six papers included in this book.
