剪切机系统是后处理首端的重要组成部分,放化所和堆工部联合承担了乏燃料组件的剪切机系统研制任务。该型燃料组件在包壳材料、结构和尺寸等多个方面与压水堆燃料存在巨大差异。为了完成剪切机相关设备的研制工作,项目组在开展第1阶段剪切工艺试验相关工作的基础上,明确了直接剪切的技术方案,开展了剪切机及配套系统的总体工艺方案研究,为第2阶段科研 The shearing machine system is an important part of the head-end of the aftertreatment. The radiochemical and composting department jointly undertake the task of developing the shearing machine system of the spent fuel assembly. This type of fuel assembly is quite different from PWR fuel in many aspects such as cladding material, structure and size. In order to complete the research and development of the related equipment of shearing machine, the project team, on the basis of carrying out the relevant work of the first stage of shearing process test, made clear the technical scheme of direct shearing and carried out the overall process plan of shearing machine and its ancillary system , For the second phase of scientific research
