Publication InformationManuscript Completed: March 2003 Prepared by Idaho National Engineering and Environmental Laboratory T.R. Wolf, NRC Project Manager Prepared for AbstractThis report documents a study performed on the set of common-cause failures (CCF) of circuit breakers from 1980 to 2000. The data studied here were derived from the NRC CCF database, which is based on US commercial nuclear power plant event data. This report is the result of an in-depth review of the circuit breaker CCF data and presents several insights about the circuit breaker CCF data. The objective of this document is to look beyond the CCF parameter estimates that can be obtained from the CCF data, to gain further understanding of why CCF events occur and what measures may be taken to prevent, or at least mitigate the effect of, circuit breaker CCF events. This report presents quantitative presentation of the circuit breaker CCF data and discussion of some engineering aspects of the circuit breaker events. |
