摘要
燃料组件压紧部件是核反应堆燃料组件的重要部件,其性能影响到燃料组件的完整性乃至安全性,是核电厂安全审查中关注的重点之一。结合燃料组件压紧部件的要求,计算板状弹簧压紧部件全寿期内的压紧力,针对压紧力不足的风险进行了原因分析,并给出了应对措施及建议。
Hold-down system is an important part of the fuel assembly,whose performance has effect on the integrity and security of the fuel assembly,and it is a concern in the nuclear power plant safety evaluation.The loads of leaf spring hold-down system in life are calculated in this paper.The reason of insufficient hold-down force is analyzed and some correction measures are proposed.
