The Treatment of physical dependencies and CCFs within the STARS environment: methodological framework and applications
A proper treatment of dependencies is at the basis of a correct system analysis and, if not correctly performed, can invalidate a whole probabilistic safety analysis (PSA) study. Here the problem of dependencies is addressed with reference to the Software Tool for the Analysis of Reliability and Safety (STARS). To this aim the information concerning the function of a component, its boundaries, its states and its failure modes is synthesized in a set of tables from which the rules used in STARS can be simply derived. The methodology has then been applied to model components which are particularly suitable for taking into account physical dependencies and CCFs. Application and numerical results are also discussed.
