Summary:PURPOSE:To simplify supporting and fixing of an upper nozzle of a fuel assembly and to improve operability and workability in combination by matching the position of a jack screw with the upper nozzle of the fuel assembly and fixing a bushing to a fixing frame by means of a set key. CONSTITUTION:The bushing 30 is fitted freely rotatably to the fixing frame 20 and further, a screw hole 31 for screwing the jack screw 35 is provided to the bushing 30 in the position offcentered from the center of rotation of the bushing 30. The lock key 32 for fixing the bushing 30 to the fixing frame 20 is provided between the bushing 30 and the fixing frame 20. The engagement of the fixing frame 20 and the bushing 30 by the key 32 is released and the bushing 30 is rotated at a prescribed angle with the fixing frame 20 when the size of the upper nozzle of the fuel assembly does not coincide with the position of the jack screw 35 munted to the fixing frame 20. The position of the jack screw 35 is matched with the upper nozzle and the pushing 30 is again fixed to the fixing frame 20 by the lock key 32.
