摘要： PURPOSE:To previously prevent the generation of stress corrosion cracking by generating the collision of multiple metal or ceramics shots, which are accelerated by the high pressure air at a specified value or less of the pressure difference between the pressure of a blow-out port and the pressure of the peripheral environment, with each other so as to convert the residual stress of the surface of the structural material from the tension to the compression. CONSTITUTION:A first chamber 3, which is provided with a horizontal part having a first beak part 2 in the tip thereof and a vertical part, is provided opposite to the working surface of the structural material of a structure in a nuclear reactor. A second chamber 5, which surrounds the horizontal part of the first chamber 3 and which has a second slit 4 in the tip thereof, is provided. A shot nozzle 7 having a blow-out port 6 in the tip thereof is provided in the first chamber 3 so as to pass through the vertical part wall. Multiple metal or ceramics shots, which are accelerated by the high pressure air at 2kgf/cm or less of the pressure difference between the pressure of the blow-out port 6 and the pressure of the peripheral environment, are made to collide with each other so as to convert the residual stress of the working surface 1 from the tension to the compression.

摘要： PURPOSE: To replace a core shroud efficiently in a short time without the necessi ty to depend on remote control by decontaminating the inside of a core in the open condition of the inside and outside of the core shroud to reduce the radiation level in the core to such a degree at which human work can be excuted. CONSTITUTION: After detaching a head 17 and a steam dryer 15 of a reactor pressure vessel 1, a water separator 16, fuels 10, structures in a shroud and the equipment installed in an upper part are detached. While an upper lattice board 5 and a core support 6 are also detached, the inside and outside of the core shroud 2 are opened by cutting and removing lower core structures. Under this condition, while the radiation level in the core is lowered by in-core decontamination with chemicals to a standard value or less which permits human work to be done, a workbench is placed at the height of the almost upper end of a shroud support cylinder 3 is installed within the shroud 2. Then, the shroud 2 is detached by cutting at its weld part with the cylinder 3. Subsequently, the upper face of the cylinder 3 is processed for shaping and forming, and a new shroud is fixed on the cylinder 3 after hanging and centering it.

摘要： PURPOSE:To straighten the bend of a work with automatic operation altogether by actuating a displacement measuring means and pressing means by a control means after supporting with a supporting means the work placed on a storage means by lifting it with a transfer means. CONSTITUTION:A start button 32 is inputted by placing the work 1 of one lot part on the upper step conveyor 2a of a work loader 2. The work 1 is lifted by the arms 13, 13 for work transfer and supported on the roller 4 of a work transfer truck 3. A displacement measuring instrument 21 is then moved toward the work 1 and when it is stopped at the prescribed position, a swing stopping device 46 motions up and down to stop the vibration of the work 1. The work 1 is then subjected to a displacement measurement by a displacement measuring instrument 21 over the axial direction and peripheral direction, which is stored in a computor 31 and based on the measurement value the conditions optimum for correcting the eccentricity are decided. The work 1 is then controlled so as to come just under the ram of a hydraulic press device 41 for the straightening objective part, the eccentricity is corrected over the whole periphery in the axial direction of the work 1 until the eccentric amount comes within the range of the set value and the work 1 is transferred onto the lower step conveyor 2b.
