摘　　要：三代非能动先进压水堆(CAP1000/CAP1400)核电厂的控制棒系统处于手动控制模式时,需要给运行人员提供实时、准确、易读的堆芯氙分布变化信息,以支持其合理决策,执行恰当的操作。本文基于CAP1000反应堆的中子物理模型,研究了氙振荡监测方法,在三代非能动先进压水堆堆芯在线监测系统中开发了氙模式图功能,可以有效监测与控制轴向氙振荡的发展。该方案具有一定的适用性,可以推广应用至其他类型压水堆核电厂。When the control rod system of the third generation passive advanced PWR(CAP1000/CAP1400)is in manual control mode,it is necessary to provide real-time,accurate and easy-to-read information about xenon distribution in the core to support its rational decision-making and proper operation.Based on the neutron physics model of CAP1000 reactor,this paper studies the monitoring method of xenon oscillation,and develops the function of xenon mode graph in the on-line monitoring system of the third generation passive advanced pressurized water reactor core,which can effectively monitor and control the development of axial xenon oscillation.This scheme has certain applicability and can be extended to other types of PWR plants.
