This paper describes results from the Nordic research project DIGREL on modelling digital I&C systems in probabilistic safety assessment (PSA). The goal has been to develop guidelines for analysing and modelling digital I&C systems. The failure modes taxonomy has been developed jointly with OECD/NEA Working Group on Risk Assessment. In addition, the modelling issue has been studied by developing a fictive, simplified PSA model representing a four-redundant distributed protection system.
