介绍了秦山核电厂首次换料方案的选择过程，利用优化技术寻找燃料组件的最佳布置，目标函数为组件平均卸料比燃耗最大。所选的换料方案具有较好的经济性与安全性，现己在秦山核电厂首次换料中成功应用．
The selection process of the first refueling scheme in Qinshan NPP was introduced, and the optimal arrangement of fuel assemblies was sought by using optimization techniques. The objective function was to maximize the fuel consumption per unit of discharge. The selected refueling scheme has good economy and safety and is now successfully applied in the first refueling of Qinshan Nuclear Power Station.
