大型压水反应堆运行过程中,Xe(氙)振荡是大家关心的一个问题。能否发生Xe荡振取决于反应堆芯部尺寸和核参数。本工作用三维反应堆芯部物理模拟器,分析了一个1300MW(e)压水反应堆内控制棒激发的Xe瞬态效应——功率密度随时间和位置的变化,即对几种控制棒组快速插入、抽出和负荷周期性变化过程中,Xe效应所导致的详尽的轴向功率、组件功率、节块功
Large-scale PWR operation, Xe (xenon) oscillation is a matter of concern to everyone. Whether or not Xe oscillations occur depends on the reactor core size and nuclear parameters. In this work, a three-dimensional reactor core physics simulator was used to analyze the Xe transient effect induced by the control rods in a 1300MW (e) pressurized water reactor - power density changes with time and position, that is, the rapid insertion of several control rod groups , Extraction and load cycle changes, Xe effect caused by the detailed axial power, component power, nodular work
