Objective The functions of the passive B systems are based on thermal-hydraulic (T-H) principles, which are not currently considered to be subject to any kind of failure. But due to the environment and to the physical phenomena that may deviate from expectation, the passive system may fail to meet its required passive function. The quantification of the T-H unreliability is often still a difficult process due to the numerous uncertainties.The methodology that we propose to develop will bring answers to the following problems:- Identification and quantification of the sources of uncertainties and determination of the important vanables,- Propagation of the uncertainties through a T-H model and reliability assessment of the T-H passive system,- Introduction of passive system unreliability in the accident sequence analysis.
