Abstract: A methodological and structured procedure to address the uncertainties related to passive safety functions is presented. The matter is treated with reference to a passive system designed for decay heat removal of advanced light water reactors, relying on natural circulation and provided with a heat exchanger immersed in a cooling pool, acting as heat sink, and connected to the pressure vessel via steam and condensate main lines. Two hazard identification used qualitative methods, as failure mode and effect an…
