摘　　要：采用KASKAD程序包对田湾核电站1~4号机组进行堆芯燃料管理优化研究,优化的燃料管理方案通过提高新组件的平均富集度减少了换料组件的类型和数量,并提高了平衡循环的循环长度。从燃料管理计算结果可以看出,堆芯各项安全参数均满足限值要求,同时具有很好的运行灵活性,提高了燃料利用率,提升了核电厂的经济效益,具有非常好的工程应用价值。This paper has done research on the optimization of core fuel management for units 1-4 of Tianwan NPP by KASKAD program package to unify the fuel management schemes.In the optimizing schemes,less varieties and quantities of fresh fuel assembles are used,however the average enrichment of new FAs is higher to increase the length of equilibrium cycle.All the safety parameters of the optimizing schemes according to the core calculation results satisfy the requirements of limiting values.The optimizing schemes are with good flexibility,and can increase the utilization of the fuel as well as increase the economic benefit of the plant,and have good engineering application value.
