剪切系统是乏燃料后处理流程中首端处理的重要设备,目的是将乏燃料元件剪切成合适长度的短段,便于对短段进行溶解,实现芯块与包壳的分离。核燃料后处理放化实验设施的剪切系统主要设置在01B热室,通过远距离隔离操作将元件棒剪成10~30mm的短段。调试中发现,剪切系统存在诸多问题:操作位 Shear system is an important equipment for head-end processing of spent fuel reprocessing process. The purpose is to cut the spent fuel components into short sections of suitable length to facilitate the dissolution of short sections and to separate the pellets from the cladding. The shearing system of the nuclear fuel post-treatment and radiochemical experiment facility is mainly set in the 01B hot chamber, and the element bar is cut into short segments of 10 to 30 mm through long-distance isolation operation. Debugging found that there are many problems cutting system: Operation bit
