摘　　要：介绍了国内法系核电机组在首循环出现一回路环路流量及堆芯总流量超过机械设计流量限值的一系列运行事件。通过对这一类型运行事件的深入探讨,找出导致事件发生可能原因,进行安全影响分析,提出了建议纠正的措施。可作为运行机组以及后续新建机组的参考。This paper introduces a series oflicenseeevents, that the domestic import from French systems of the nuclear power plants in the first fuel cycle appeared RCP loop flow and core total flow over the mechanical design flow limit. Study these event to identify the root cause, also analysis of affect to system safety, and provide proposed corrective measures. Reference for operating units and subsequent new units, in order to avoid the recurrence of similar events.
