摘　　要：田湾核电站1号机组第5次换料大修期间,根据燃料组件检查结果,开展了紧急换料设计。1号机组第6循环堆芯装载策略具有不同于正常换料的特点,例如燃料装载不对称、部分辐照过的燃料组件移动到对称象限、堆芯功率分布不对称等。另外,堆芯装载策略考虑了TVS-2M先导燃料组件的位置要求。经第6循环寿期初物理试验和堆内测量系统验证,堆芯装载方案设计结果满足各项测量准则要求,且堆芯运行参数符合设计预期。During the 5th refueling outage of Tianwan Nuclear Power Station Unit 1,according to the fuel assembly inspection results,emergency refueling design has been carried out.The in-core loading scheme of Unit 1 Cycle 6 has special characteristics from normal refueling.For example,fuel loading is asymmetry,some burned fuel assemblies are moved to symmetrical sectors,and in-core power distribution is asymmetry etc.In addition,in-core loading scheme has been considered the requirement on positions of TVS-2M pilot fuel assemblies.Verified by physics tests and in-core measurement system at beginning of cycle 6,design results of in-core loading pattern meet all measurement criteria and requirements,and in-core operation conditions conform to design anticipate.
