由于变形相关组件形状发生变化,无法配插到燃料组件或存放架内进行贮存,一般是将其临时放入乏燃料水池贮存格架中的空贮存小室内,这种状态下的变形相关组件失去支撑,变形相关组件棒体会在自身重量作用下发生弯曲,长时间处于此状态下可能导致棒体破损,致使里面的物质泄漏而污染乏燃料水池.文章中工器具的整个研发是以秦山第二核电厂作为试验场所,以其乏燃料水池内的3组变形相关组件作为研制对象,最终研发出一套适用于变形相关组件安全贮存的工器具,本套工器具保证了变形相关组件的完整性.

Due to the shape of the deformation associated core components is changed, it can't be inserted to fuel assembly or storage rack, and it can only be stored in spent fuel storage cell. Deformation associated core components in this state will lose support. Rods of deformation as-sociated core components become bend under the weight of its own, which may be damaged for a long time in this state, thus the material inside leaked and the spent fuel pool is contami-nated. Therefore, we must design a tool, which can safely store the deformation associated core components. Qinshan Phase Ⅱ is selected as the test site for the whole development process, with three groups of deformation associated core components (a group of primary neutron source assembly, a group of burnable poison assembly, a group of rod cluster control assembly) in the spent fuel pool as development objects. Ultimately a set of tools suitable for the safe storage of deformation associated core components are developed, which ensure the integrity of the defor-mation associated core components.
