Estimating common cause failure rates for pumps in nuclear reactors

PDF Version Also Available for Download.

Description

Common cause fault rates are estimated for certain pumps in US commercial nuclear reactors, based on Licensee Event Reports from January 1972 through April 1978. Vesely's binomial failure rate model is used, with the methodology of Atwood (1980, NUREG/CR-1401). Issues discussed include correct classification of reported events as common cause or not, proper grouping of the pumps into common cause systems, outlier detection, and checking the adequacy of the model. Reasons are given for preferring Bayesian to classical methods for this application.
