摘　　要：由于在CNP650堆型的控制棒反作用带内,控制棒对轴向功率偏差ΔI的控制效果较差,因此,国内外轴向功率偏差ΔI因反作用影响导致的超带事件时有发生。本文采用堆芯三维计算程序ORIENT,分别从燃耗、功率和机组循环3个方面对CNP650堆型的控制棒反作用进行研究分析,并给出反作用带的具体区间,以及该区间内控制棒对ΔI的控制效果。研究结论可为运行操纵员控制ΔI提供技术支持。Due to the poor control effect of control rods on axial power deviationΔI within the control rod reaction zone of CNP650 reactor,overband events caused by the reaction effect on axial power deviationΔI occur from time to time both at home and abroad.In this paper,the three-dimensional core calculation program ORIENT is used to study and analyze the control rod reaction of CNP650 reactor from three aspects:burnup,power and cycle.The specific interval of the reaction zone and the control effect of control rods onΔI within this interval are given.The conclusions provide technical support for operation operators to controlΔI.
