Abstract: ABSTRACTSimulations of containment phenomena during severe accidents in a pressurized water reactor induced by large-break loss-of-coolant and station black-out were performed, with different actuation of Passive Autocatalytic Recombiners and containment sprays. The analyses of results provided insights about the influence of severe accident management on the in-containment combustion risk.
