Abstract
The article describes a number of activities that were part of a major Nordic co-operation project which was recently performed, and which aimed at providing state-of-the-art guidance on the handling of dependent failures in nuclear power plants, both in operation and safety management, and as a part of plant PSA:s. This includes a rather wide scope of activities ranging from reviewing and describing available sources of data on CCF and CCF modelling techniques to the analysis of the efficiency of various protective measures against dependent failures in safety related equipment. A set of guidance documents was issued. The project also included a number of data analysis pilot applications, where CCF events in the ICDE database were analysed applying the impact vector method for several types of safety critical components.
