Plant specific fire PSA considering measures taken to lower fire hazard and improved core damage frequency in a model plant

摘要

Fire PSA is a probabilistic analysis of fire events and their potential impact on the nuclear safety of a plant. Using probabilistic models, fire PSA takes into account the possibility of a fire at various plant locations (zones); the detection and suppression of the fire; the effect of the fire on safety related cables and equipment; the possibility of damage to these cables & equipments and assessment of the impact on plant safety‥
