Abstract

A mathematical model for the loading pattern（LP） optimization for a pressurized water reactor（PWR） was established based on Daya Bay Nuclear Power Plant.The discreet,multi-objective particle swarm optimization algorithm was integrated with the core physics calculation code "Donjon" based on finite element method,and assembles group constant calculation code "Dragon",developing an optimizing code for fuel arrangement.This code is applied to optimize the first cycle loading of Daya Bay Nuclear Power Plant.The result shows that,compared with the reference LP,the core effective multiplication factor increases by 9.16%,while the local power peaking factor is lower than 1.4,satisfying the safety requirement.
