摘　　要：核电厂堆芯装料能否顺利进行直接影响着核电厂换料大修的关键路径和大修工期。针对核电厂反应堆堆芯装卸料机燃料操作的特点,分别从装卸料机的堆芯定位精度、燃料组件变形等分析其对堆芯装料的影响,并提出了几种缓解措施来应对堆芯装料过程遇到的困难,为后续大修解决装料过程中遇到的困难提供借鉴和处理措施。The smooth progress of core fuel loading in nuclear power plants directly affects the critical path and overhaul period of nuclear power plant refueling overhaul.In view of the characteristics of the fuel operation of the loading and unloading machine in the nuclear power plant reactor core,the core positioning accuracy of the loading and unloading machine and the deformation of the fuel assembly are analyzed,and several mitigation measures are proposed to deal with the difficulties in the loading process.It provides a reference solution for the difficulties encountered in future loading process.
