Abstract
In order to analyze and effectively control the xenon oscillation caused by the power change or control rod position change process of VVER,in this paper,the steady-state axial power distribution of the core at different positions of the working rod group is calculated through the KASKAD program package based on the actual situation of the fourth cycle of Tianwan Nuclear Power Station Unit 4.The radial power distribution when a single beam of control rods in motion is calculated.The reactivity introduced by xenon changes with time when the reactor power changes is analyzed.By adjusting the initial position and final position of the working group rods,the influence of the xenon oscillation caused by the power change on reactivity is reduced as much as possible.The position of the working group rods provides a reference for the crew operator.关键词
