摘　　要：秦三厂CANDU-6型重水堆通过插入停堆棒可向反应堆中引入足够多的负反应性,来终止反应堆的自持链式裂变反应,保护反应堆的安全。停堆棒的动作控制电机由电机控制中心供电。通过对停堆棒电机供电间隔的历史缺陷进行分析、研究,找出问题原因,并提出改进措施,以提高停堆棒电机供电间隔在实际应用中的稳定性。The CANDU-6 heavy water reactor of No.3 Qinshan Nuclear Power Plant can introduce enough negative reactivity into the reactor by inserting the reactor stop rod to terminate the self-sustaining chain fission reaction of the reactor and protect the safety of the reactor.The motion control motor of the stopper is powered by the motor control center.Through the analysis and study of the historical defects of the power supply interval of the reactor rod motor,the cause of the problem is found,and improvement measures are proposed to improve the stability of the power supply interval of the reactor rod motor in practical applications.
