摘　　要：AP1000核电机组化学和容积控制系统设计有反应堆补水控制系统。其中“混合”补水模式用于向一回路提供与其相同硼浓度的含硼水。在补水过程中,硼浓度偏差过高会产生报警,并导致反应堆补水控制系统停止。由于设备调节及精度不足,可能会导致设定硼浓度过高或过低,补水硼浓度偏差过大。该文从依托项目调试经验中分析可能存在的原因,并改进措施后再次验证,为后续非能动系列机组反应堆补水控制模式试验提供一定的指导。Reactor Makeup Control System is designed in Chemical and Volume control system in AP1000 nuclear units.RMCS Blend mode is used to supply water with the same boric acid concentration of primary system,which will cause alarm with a high deviation of boric acid concentration during makeup of Blend Mode.Also RMCS will stop.The boric acid concentration deviation will be high when RMCS boric acid concentration setpoint is too high or too low,because instruments have low accuracy.This paper analyzes the possible reasons and makes some measures to verification,so as to supply guidance for Reactor Makeup Control System test in following passive nuclear units.
