摘 要:核燃料在核电厂经过裂变反应后,成为具有高放射性的乏燃料。乏燃料被运送至乏燃料后处理厂后,会被放入乏燃料准备水池。当进行首端处理时,使用提升机将乏燃料组件从水下提升至剪切热室下方,以备后续处理。组件提升机是乏燃料首端处理的核心设备。文章从组件提升机结构特点入手,剖析液压缸、提升小车和机架等关键零部件的作用、制造技术难点,提出切实可行的解决方案,抓住影响设备性能和精度的关键点进行严格、有效的质量管控和风险防控,同时制作专用试验台架来模拟现场实际工况,以测试组件提升机的整体性能。试验结果表明,提升机的各项性能和技术指标均满足设计要求,充分证明了制造工艺的合理性和质量的可靠性。After the nuclear fuel goes through the fission reaction in the nuclear power plant,it becomes the spent fuel with high radioactivity.After the spent fuel is transported to the spent fuel reprocessing plant,it is placed in the spent fuel preparation pool.During head-end processing,a hoist is used to lift the spent fuel assembly from underwater to below the shear heat chamber for subsequent processing.Component hoist is the core equipment for spent fuel front-end processing.Starting with the structural characteristics of the component elevator,this paper analyzes the functions of key components such as hydraulic cylinder,lifting trolley and frame,and the difficulties in processing technology,and puts forward practical solutions to seize the key points that affect the performance and accuracy of the equipment for strict and effective quality control and risk prevention and control.At the same time,a special test bench is made to simulate the actual working conditions on site.To test the overall performance of the component elevator.The test results show that the performance and technical indexes of the hoist meet the design requirements,which fully proves the rationality of the manufacturing process and the reliability of the quality.
