摘要： PURPOSE:To keep a proper radial distance between stabilizers and a distance between a pressure vessel and the stabilizers and to enable an easy design and installation work, by providing a stabilizer with projected parts with concave brackets. CONSTITUTION:The attached figure shows a vertical cross section of a nuclear reactor pressure vessel and its periphery. A convex bracket 9 projected from the pressure vessel 3 is fitted into a concave bracket 15 projected from a pressure vessel stabilizer 7. Upper and lower plates 17 and 18 of the concave bracket 15 are fitted into a projected part 16 of a shield wall 14 surrounding the pressure vessel 3, with a york 10. The york 10 is connected to a stabilizer bracket 13 which forms the upper and lower plates themselves, via a rod and a belleville spring which are not shown in the figure. As the stabilizer 7 is placed on the shield wall 14, an interval between the each stabilizer can be firmly kept and therewith an easy designing can be attained. Moreover, as an interval between the surrounding wall of the vessel 3 and the stabilizers 7 is also firmly kept, the designing and installation can be easily executed. No.8 in the figure shows a containment stabilizer.

摘要： PURPOSE:To form a bent system by a relative displacement absorption structure and to remarkably decrease a design load by providing a bellows for connecting each bent pipe between a dry well of the bent pipe body and a torus. CONSTITUTION:A bent pipe bellows 9 is provided on an intermediate part of a dry well 2 of a bent pipe and a torus 3. The bent pipe bellows 9 connects the dry well 2 side of the bent pipe and the suppression torus 3 side, and on its outside periphery, a detachable bellows cover 20 is provided. Also, a bent system is not supported by the torus 3 through a support but supported by welding 27 of the bent pipe 5 and a through-part of the torus 3. In such a way, as for a nuclear reactor store container, the influence caused by a mutual relative variation of the dry well 2 and the suppression chamber torus 3/bent system is absorbed.

摘要： PROBLEM TO BE SOLVED: To provide a method for sufficiently reducing a residual stress of such a portion as a decontamination port of a pipe in a recirculation system, at which a non-condensable gas stays. SOLUTION: This method for reducing the residual stress comprises the steps of: substituting vapor for the non-condensable gas which stays at the part to be executed to discharge the non-condensable gas from the inside of the part; further substituting water for the vapor which has substituted for the gas in the part; and then heating an outer surface of the part in a state of having filled the part with the water to generate temperature difference in a thickness direction of the part. The method can remove the non-condensable gas, and accordingly can sufficiently reduce the residual stress in the part at which the non-condensable gas stays. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To facilitate and rationalize piping replacement work by providing the outside surface of a cylindrical liner with grooves having parts penetrating this cylindrical liner and forming shape memory allay rings and the cylindrical liner to a fit structure. SOLUTION: The shape memory allay rings 1 are manufactured by using shape memory alloys. These allays are made to memorize a shape in such a manner that the diameter thereof is reduced by heating the allays to their austenitic transformation temp. or above. The cylindrical liner 2 to be inserted into the inner side of the shape memory allay rings 1 is provided with two rows of annular projecting parts 3a, 3b in its circumferential direction and the outside surface is provided with the grooves 5 having the parts penetrating the inside of the liner. When the shape memory alloy rings 1 restore the shape to the reduced diameter by inducing the austenitic transformation, the cylindrical liner 2 is deformed and the annular projecting parts 3a, 3b formed on its inside surface bite into a piping, thereby clamping the piping. In such a case, the rigidity of the cylindrical liner 2 is enhanced if the width of the grooves 5 on the outside surface of the cylindrical liner 2 is made small and the number of the grooves is reduced.

摘要： PURPOSE:To shorten the period for constructing a reactor container by installing threaded reinforcing bar couplers at one end of reinforcing bars near the surface of the reactor container and joining the same to the floor slab reinforcing bars of a reactor building, then constructing the reactor container. CONSTITUTION:The threaded reinforcing bars 10 are used as the reinforcing bars of the floor slab 2 in order to construct the floor slab 2 of the reactor building 1 after the reactor container 3 is erected. The bars 10 are connected to the threaded reinforcing bar couplers 12 exposed on the concrete surface of the container 3. The reinforcing bars 10 integral with the reinforcing bars 11 of the container 3 are projected from the concrete surface and the arrangement of reinforcement of the floor slab 2 is executed. The concrete of the floor slab 2 is then placed and the building 1 is erected while the other parts of the buildings 1 are constructed. The construction of the container 3 can then be progressed independently from the building 1. The period for constructing the container 3 is thereby shortened.
