Abstract

Data bases of five studies concerned with failure probabilities of diesel generator systems in nuclear power plants are analyzed, and methods used in these studies for the estimation of common-cause failure probabilities are described. With the use of the moments-matching method, essential information given in the studies is supplemented with calculations of multiple-failure probabilites. The associated confidence bounds and the beta- and C-factors are estimated. US and Swedish-Finnish experience regarding the relative contributions (from testing and maintenance, design, manufacturing and installation, and external events) to the observed dependent errors are compared. This article describes the similarities and discrepancies among the studies and offers possible reasons for the discrepancies.
