Résumé

The paper describes the general methodology used in the IPSN level 2 PSA first version for quantifying the physical phenomena and assessing the uncertainties. This methodology is based on “physical modules” which definition is given. An evolution of this methodology towards the use of fast simplified physical models has been undertaken.
