摘要： PROBLEM TO BE SOLVED: To provide an air pallet carrying device capable of easily moving an air pallet without using compressed air in an empty load state. SOLUTION: In this air pallet carrying device 10, the air pallet 20 detachably mounted on a lower surface of a storage frame 11 receives the supply of air pressurized in a diaphragm 22 having an air blowoff hole attached on a lower surface of a frame 21. An air film is formed between the diaphragm 22 and a floor surface 2 by air blowing out from an air blowoff port, thereby carrying a heavy article loaded on the storage frame 11 with the storage frame 11. Wheels 24 separating from the floor surface 2 when the air is supplied into the diaphragm 22 and grounding on the floor surface 2 when the supply of the air is stopped are provided on the frame 21 lower surface of the air pallet.

摘要： PURPOSE:To check up the inside of a heat exchanger safely and efficiently by a method wherein a moving stage is moved by a remote operation along a guide rail inserted into a secondary-side tube sheet of the heat exchanger, a checking head is moved in an orthogonal direction from the moving stage and an image is picked up by a TV camera at the fore end of a probe. CONSTITUTION:A guide rail 2 is inserted from a checking hole 105 of a steam generator by utilizing the existing hole of a tube lane block 103 and a steel belt 8 for a checking probe is let out along the rail 2 from a winding drum 4 through a drive part 10. Then, a moving stage 50 holding a checking head 9 fitted to the fore end of the belt 8 is moved. Driving an air cylinder by compressed air sent from an air distributing unit 6, the moving stage 50 turns the direction of the belt 8 to an orthogonal direction and an image of the inside of a heat exchanger is picked up by a TV camera of the checking head 9 fitted to the force end of the belt 8. These functions are controlled by a remote operation through the intermediary of an X-axis control mechanism, a Y-axis control mechanism, a Q-axis control mechanism and a video processor 7.

摘要： PURPOSE:To remedy a deformed fuel assembly to contrive the charge thereof in a specified position in a reactor core by providing the device for a self-aligning mechanism, a guide device, and a press mechanism. CONSTITUTION:A charge auxiliary device 20 consists of a self-aligning mechanism 21, a guide device 22 and a press mechanism 23 and is attached to the lower end of a column of a fuel handling crane through an adapter. The device 22 is movable before and behind, right and left for the upper frame of the mechanism 21 and provided with a box 36 having a drive system of the mechanism 23 in the interior thereof. The arrangement of a side pin 37 projected on the lower face of the box 36 coincides with a passage hole in each partition of a lower part reactor core plate. The edge of the pin 37 is tapering and an inclination 38 is formed. A support plate 39 is arranged downward of the box 36 and supported vertically movably by a column 41 slidably penetrated in a sleeve 40 fixed on the side face of the box 36. In addition, a side plate 42 extends upward from the upper face of the support plate 39 to lock with a roller 43 attached to the box 36 so as to ensure smooth vertical motion of the support plate 39. The mechanism 23 has a press plate supporting the lower part of a deformed fuel assembly, which is corrected by moving it before and behind, right and left.
