Sensitivity analysis of the model of a nuclear passive system by means of Subset Simulation

Abstract : Passive safety systems are commonly considered to be more reliable than active systems, and for this reason are expected to improve the safety of nuclear power plants. However, their behavior and modeling are affected by considerable uncertainties. In this paper, the recently developed Subset Simulation method is employed to perform an efficient sensitivity analysis for identifying the key parameters which influence the uncertain behavior and, thus, the failure probability, of a nuclear passive system of literature.
