摘　　要：在氙振荡过程中,堆芯的功率分布会发生变化,从而导致轴向功率偏差的波动。这种波动不仅影响反应堆的热效率和经济性,还可能引发严重的安全问题。为此,提出压水堆核电站氙振荡过程中轴向功率偏差控制方法。首先,分析氙振荡产生原因;其次,以慢化剂温度与氙毒为主要因素,分析影响轴向功率偏差的原因;最后,设计一种机械补偿策略,实现轴向功率偏差控制。实验结果表明:通过实施压水堆核电站氙振荡过程中轴向功率偏差控制,在氙振荡过程中的轴向功率偏差得到了有效控制。During the xenon oscillation process,the power distribution of the core will change,leading to fluctuations in axial power deviation.This fluctuation not only affects the thermal efficiency and economy of the reactor,but may also cause serious safety issues.To address this issue,a study is proposed on the control method of axial power deviation during xenon oscillation in pressurized water reactor nuclear power plants.Firstly,the causes of xenon oscillation were analyzed.Secondly,the factors affecting axial power deviation were analyzed with the main factors of moderator temperature and xenon toxicity.Finally,a mechanical compensation strategy was designed to achieve control of axial power deviation.The experimental results show that by implementing the axial power deviation control method during the xenon oscillation process in pressurized water reactor nuclear power plants,the axial power deviation is effectively controlled during the xenon oscillation process.
