摘　　要：本研究通过对国内外因制造因素导致燃料破损案例的跟踪,对燃料组件制造环节可能导致堆内燃料破损的环节开展了工艺优化和管理措施,主要包括制造过程中异物控制、焊接工艺控制、拉棒工艺改进、堵孔夹钨检测等工艺优化和管理改进,提升了燃料制造质量,实现了燃料组件无制造原因导致破损的目标。By following the cases of fuel breakage caused by manufacturing factors at home and abroad,this paper carries out process optimization and management measures for the fuel assembly manufacturing process which may lead to the fuel breakage in the reactor,which mainly include the process optimization and management improvement of foreign matter control,welding process control,rod drawing process improvement,hole blocking and tungsten pinch detection.They improve the fuel manufacturing quality,and realize the goal of non-manufacturing failure of fuel assembly.

关 键 词：燃料破损 经济性 工艺优化 管理改进
