Method for measuring reactor core power distribution of pressurized water reactor under dynamic xenon condition

The invention discloses a pressurized water reactor core power distribution measurement method under a dynamic xenon condition. The method comprises the following steps: 1, implementing a reactor core power distribution measurement test under the dynamic xenon condition to obtain an RIC file under the dynamic xenon state; 2, simulating the whole process from reactor core power rising to a balanced xenon state by adopting reactor core physical analysis software, and obtaining a time rule of an activity calculation value of each detector channel; thirdly, based on the RIC file in the dynamic xenon state, deducing to obtain a measured value of the activity of each detector channel in the balanced xenon state, and outputting the RIC file in the balanced xenon state; and 4, based on the RIC file and the theoretical library in the balanced xenon state, obtaining a measured value of reactor core power distribution in the balanced xenon state through reactor core power reconstruction software. The method is suitable
