During the 28-30 January 2019 meeting on Digital I&C PSA – Comparative application of Digital Instrumentation and Control (I&C) Modelling Approaches for Probabilistic Safety Assessment (PSA) hosted by GRS, participants of the task agreed that modelling of the mechanical systems should be shared, so that it is not a cause of variations in results. EDF proposed to distribute its current modelling. This document describes the EDF RiskSpectrum® model of mechanical systems, based on system and failure data description in Appendix A, Volume 1.
