The problem of analyzing and quantifying common-cause failures (CCFs) is fundamental in conducting probabilistic safety studies. The use of experience feedback is crucial in addressing this problem, and it is possible to draw in a complementary manner on national experience feedback data bases and ad hoc on-site audits. These two approaches differ in objectives and methods, but are both equally necessary. In this paper, the use of these two approaches and the results obtained are analyzed and are illustrated by two concrete examples: (1) a national collection of >1200 event and failure records concerning the problem of CCFs in EdF 900-MW (electric) units; and (2) an analysis based on audits carried out at an EdF 1300-MW(electric) reactor site.
