Transient analysis xenon strategy determination method and device, and computer equipment

The invention relates to a xenon strategy determination method and device based on transient analysis and computer equipment. The method comprises the following steps: determining a target final state xenon strategy according to final state reactor core power; determining a target change range and a corresponding target initial disturbance state xenon strategy according to the target axial power deviation; and determining a target xenon strategy according to the target final state xenon strategy and the target initial disturbance state xenon strategy. As the xenon transient database comprises the corresponding relation between the xenon strategy and the axial power deviation change range, the xenon transient data can provide the axial power deviation covering a large range for different fuel management schemes and reactor types; in addition, in the process of determining the xenon strategy according to the change range, the target axial power deviation is more easily searched, repeated iterative calculation i
