摘要： PROBLEM TO BE SOLVED: To provide a radioactive waste sorter capable of sorting efficiently the waste wherein all sorts of articles which are different in a radiation dose rate, the quality of material, the shape and the size are jointed together into respective articles having a high or low radiation dose rate, or into combustibles and noncombustibles.
SOLUTION: A waste mixture is sorted respectively into extremely small, small, medium and large articles by a vibrating screen 1. The extremely small articles are stored in a combustible container 5. The small articles are sorted into metals and combustibles by a color difference sorter 2, and the combustibles are stored in the combustible container 5 and the metals are stored in a noncombustible container 7. The medium articles are sorted into metals and combustibles by a dose rate sorter 32, and the combustibles are stored in the combustible container 5 and the metals are stored in a noncombustible container 6. The large articles are sorted into metals and combustibles by an image recognition sorter 4, and the combustibles are stored in the combustible container 5 and the metals are stored in the noncombustible container 7. Resultantly, the combustibles are stored in the combustible container 5, and the metals having a high dose rate are stored in the noncombustible container 6, and the metals having a low dose rate are stored in the noncombustible container 7.

摘要： PROBLEM TO BE SOLVED: To cut efficiently when an activated upper lattice plate is shredded before disposal in the water in an apparatus storing pool of a nuclear power plant.
SOLUTION: While allowing an abrasive water jet to hit onto the upper lattice plate 1 from a cutting nozzle 13 in the water in the apparatus storing pool 14, the cutting nozzle 13 is moved from the upside to the downside by a mast 38 of a multi-axial manipulator, to thereby execute the first cutting 8 of a crossing part of the lattice on the upper lattice plate 1 along a cutting line oblique to the lattice plate. Thereafter, while moving the cutting nozzle 13 from the upside to the downside by the mast 38 of the multi-axial manipulator, the second cutting 9 is executed at a position adjacent to the crossing part of the lattice of the upper lattice plate 1. The two-spot cutting is executed at the crossing part of each lattice, to thereby cut and divide the lattice plate of the upper lattice plate 1 into sawtooth-shaped cut pieces 25 including the lattice plate existing on two sides of the lattice.

摘要： PROBLEM TO BE SOLVED: To suppress contamination of equipment caused by intrusion into an equipment storage domain, of contaminants generated at the cutting time by a cutting work in the equipment storage pool of a nuclear power plant.
SOLUTION: The equipment storage pool 41 of the nuclear power plant is partitioned by double curtains 1, 2, to be thereby divided into a cutting pool 9 and a storage pool 8, and clean water 12 acquired by purifying pool water in the cutting pool by a purification device 6 is injected into a pocket 3 formed between the double curtains 1, 2. As for a gap of the partition generated in a sealing part between the curtains 1, 2 and the pool inner surface, the clean water 12 is run from the pocket 3 into the cutting pool 9 and the storage pool 8 via the gap, to thereby prevent contaminated water generated on the cutting pool 9 side from entering the storage pool 8 side via the gap.

摘要： PURPOSE:To make a valve resist to strong load that a valve body is subject to by a mechanism wherein a trunnion section is penetrated by a valve shaft, and the valve shaft is connected and supported by a reinforcing rib. CONSTITUTION:A valve shaft 6 mounted to a valve body 10 is inserted into a penetrating hole 11 of a trunnion section 4, and has length extending over a through hole 12 formed to the first rib 5A, a diameter of a nose section up to the first rib 5A from the trunnion section 4 is slightly reduced and the nose section is fitted to the through hole 12. The valve shaft 61 fitted to the through hole 21 is welded and connected to the through hole 12, and unified with the valve body 10. In the penetrating hole 11, on the other hand, a key 13 is disposed so that the rotational torque of the valve shaft 61 can be transmitted sufficiently to the valve body 10. Bending moment can be received mainly by the first rib 5A connecting section and shearing force by the trunnion section 4, thus resisting great load.

摘要： PURPOSE:To prevent the bulging-out of a packing and further prevent the leakage by a method wherein a packing at the ball valve type seal ring is made of a metal ring lined with a resilient member. CONSTITUTION:When an opening and closing operation water pressure for the seal ring 6 is fed either at an closing inlet port 12 or an opening inlet port 13 to move the seal ring 6 in a direction of water flow, the operating water pressure is sealed by a close contact surface between a rubber plate 17 and the seal ring 6 as well as a close contact surface between the water seal ring 14 and the guide planes 7, 8 under a resiliency of the rubber plate 17, the seal ring 6 is moved in a direction of acting pressure of the operating water pressure to enable either an opening or closing operation of the valve body 12. When a valve body 1 is bulged out under a high pressure, an outer circumference of the seal ring 14 keeps a water sealing function in response to a bulged out of the valve body 1 under an existence of the slit 15 of the sealing ring 14 and a resiliency at the margin of the rubber plate 17.

摘要： PURPOSE:To seal water uniformly and positively while decreasing the capacity of a servo-motor, by obtaining water sealing force by working the pressure of water currents to seal portion material connecting portions when closing this valve. CONSTITUTION:When closing this valve, a cylinder gate 15 is moved up to a discharge opening end portion by means of a servo-motor, and a connecting surface 18A of the seal ring 18 and a connecting surface 17A of a seat ring 17 of a discharge body 12 are contacted. A pressure receiving surface 18B at the water current opposite side is subject to pressure by water currents in the seal ring 18, the connecting surfaces 17A, 18A are sticked fast by the push force and water seal is formed. In this case, precise watertightness is obtained because water pressure uniformly acts on the pressure receiving surface 18B made up along the whole circumference of the seal ring 18. Deflection to the seat ring 17 side increases in the seat ring 18 when the ring 18 receives pressure owing to a round hole 18C built up at the water current opposite side, and water sealing action becomes more conspicuous.
