The paper first presents general objectives, steps of development and elements of methodology of the 900 MWe PWR level 2 PSA achieved by the IRSN.
It then highlights some of the most important specificities of the IRSN study: a detailed level 1 to level 2 interface, use of so-called physical models to represent physical phenomena in the Accident Progression Event Tree (APET), a specific and detailed model to assess containment leakage through penetrations, an on line simplified model physical model to estimate the radioactive releases and a powerful dedicated software for the APET quantification.
