Abstract

PURPOSE: To easily carry out the disassembling work of an irradiated subassembly by pulling out a fuel pin by moving a carrying body mounted with a fuel pin locking device in the axial direction of a fuel subassembly supporting body or in a plane crossing the axial direction. CONSTITUTION: Both ends of a cylinder 20 are connected to a rear table 24 and a side slipping table 26 with universal joints 22 and the cylinder 20 is moved in a plane parallel to the exposed end 13 of a fuel element 12 by means of a step motor 28 and a lead screw 30. Since a chuck assembly 32 connected to a carrying body 18 is mounted on a fuel pin coupling device 16 by means of a cylinder 34, the movement of the assembly 32 in the axial direction is performed by means of the cylinders 20 and 34. The device 16 is matched with a positioning socket 38 by driving the device 16 by means of the cylinders 20 and 34 and further driven to a pin pulling position by means of the motor 28. At the pulling position, a nuclear fuel subassembly can be disassembled easily, by moving the assembly 32 forward by energizing the cylinder 34 and engaging the assembly 34 with the fuel pin.
