Analysis of Common Cause Failures Based on Operating Experience : Possible Approaches and Results
Abstract The analysis and quantification of common cause failures may be performed in two complementary ways: by using national operating experience records, by specific on-site investigations. The paper describes their merits and results of both approaches and illustrates them with examples. In particular common cause failures have been analysed and quantified trough two studies performed at EDF: Nationwide compilation of more than 1 200 events or failure sheets concerning common cause failures in 900 MWe units. An analysis based on investigations carried out on a 1300 MW site. The paper concludes that common cause failures are unavoidable and not simple solution is available but the quantification becomes possible and orders of magnitude are know (for the second order). Finally, the analysis of operating experience is an indispensable condition of success to prevent common cause failures.
