摘要： An ultrasonic transducer carried by rod means of dimensions such that it may be inserted in the assembly between an end piece and the caps of the element, and a crossed movement moving mechanism for bringing the transducer above the different elements. It further comprises a mechanism for moving rod elements in the longitudinal direction of the fuel elements. The transducer is set up on rod elements with at least one degree of freedom about a shaft transversal to the fuel elements so as to be able to be applied flat against the end face of a cap.

摘要： The apparatus is for dismounting nuclear fuel assemblies comprising a skeleton having an upper end piece, a lower end piece, guide tubes connecting the end pieces and fuel rods maintained by grids between the end pieces. The apparatus comprises a cell displaceable vertically in a water tank and provided, at its upper part, with a base plate having an opening for passage of one said fuel assembly and provided with means for gripping an upper part of the bundle of fuel rods. A centering unit is operable by a handling tool and is arranged for gripping the upper end piece of a fuel assembly. The guide tubes may be disconnected from the upper end piece while the bundle of fuel rods is retained in the cell.

摘要： The apparatus is intended for rebuilding an assembly comprising a skeleton formed by two end members connected by tie rods attached to the end members and grids distributed between the end members along the tie rods and adapted to retain a cluster of fuel rods trapped between the end members. The apparatus comprises a first chamber (AI) for receiving a fuel assembly, a second chamber (AS) for receiving a new skeleton, a repair station comprising a lift adapted to receive the two vertically disposed aligned chambers and to bring the chambers to a level such that there subsists a layer of protective water above the rods, a transfer tool (106) to draw one fuel rod at a time into the skeleton from the assembly contained in the first chamber, and means for mounting the end members on the skeleton.
摘要翻译：该装置旨在重建包括由两个端部构件形成的骨架的组件，该两个端部构件通过连接到端部构件的连接杆和沿着拉杆分布在端部构件之间的网格连接，并且适于保持被夹在端部构件之间的燃料棒。该装置包括用于接收燃料组件的第一腔室（AI），用于容纳新骨架的第二腔室（AS），修理站，其包括适于容纳两个垂直设置的对准腔室的升降机，使得在杆上方存在一层保护水，一个转移工具（106），用于一次将一个燃料棒从包含在第一室中的组件吸入骨架中，以及用于将端部构件安装在骨架上的装置。
