摘　　要：针对大亚湾核电站原始设计中反应堆余热排出系统(RRA)的入口隔离阀控制逻辑的设计不满足单一故障的情况,提出增加2台压力变送器的改进方案。通过定量化计算,评价改进方案对RRA及机组堆芯损坏的影响。Because of the origin design for control logic of entrance isolation valve in RRA system was not conform to the single failure criterion, the improvement scheme, which would be added two sets of pressure transmitter, has been raised. The effect of RRA system and the damage of reactor core have been evaluated through quantitative calculation about the scheme of the modification.
