Abstract

The International Common Cause Data Exchange (ICDE) project aims at collecting both complete and potential CCF events. These events are called ICDE events. In this paper, the collected events are analyzed with respect to the major contributions to complete common cause failure of redundant systems. The analysis shows that the majority of complete common-cause-failures involve faulty human actions. Consequently, the event descriptions of the complete common-cause-failures have been screened to identify typical scenarios of human involvement of such actions and to quantify their frequencies of occurrence. The assessment has led to several recommendations aimed at improving operation, maintenance and testing procedures, improving the requalification process, intensifying operator training, introducing economically better designs, etc.
