The paper presents the methodology used by the IRSN to establish the physical models of the Accident Progression Event Tree for level 2 PSA. The methodology supposes to realize intensive sensitivity studies to cover the situations calculated by the APET and the uncertainties. Three examples of application are proposed: ex-vessel steam explosion, direct containment heating and containment failure.
