Research of Core Power Distribution Reconstruction Method by Disturbances Searching

摘要

This paper proposed a new method of power distribution reconstruction. The feasibility of this method is verified by using unit 2 reactor of Qinshan No.2 Nuclear Power Plant as calculating model. The method can be used to find out the deviation between theoretical calculation value and actual measured value of power, which is caused by xenon toxicity fluctuation and moderator temperature field changes, and reconstruct the distribution of reactor core power accurately.
