摘要： PROBLEM TO BE SOLVED: To improve aseismicity by providing a suppression chamber for preserving cooling water around a pedestal provided surrounding near the core of reactor pressure vessel. SOLUTION: A reactor pressure vessel 3 is fixed at the lower end part on a support cell 22 and at the upper end side on the top slab 14 side of the containment shell 4. Around the pressure vessel 3, a cylindrical pedestal 23 is stood so as to surround the vicinity of the core part 3a apart for a specific gap. Between the upper end part and the containment shell 4, a ring shape diaphragm floor 24 is bridged so that a drywell 25 for guiding steam line in the upper part and a suppression chamber 26 for reserving cooling water in the lower part are partitioned by the floor 24. Inside the pedestal 23, a vent pipe 27 for guiding steam leaking into the drywell 25 is provided. On the inner wall side, a biological shield wall 28 surrounding the vicinity of the core 3a is provided.

摘要： PURPOSE: To provide a seismic device designed for a high rising structure or heavy structure or an atomic power plant structural body or an oil tank which may cause a disaster when it is collapsed, and especially, a seismic device capable of withstanding vertical vibrations caused by an earthquake with a vertical shock. CONSTITUTION: An excavation hole 3 is drilled directly from a surrounding area of a side wall of an existing structural body to be protected to an immovable basement at the underground depth based on a curved slanting excavation method. An anchor material 5 which bundles a steel bar material 4 is inserted from the upper part of the excavation hole and buried to the lower part of the excavation hole 3 which reaches the immovable basement 2. A curved anchor (b), which fills up the clearance between the anchor material 5 and the excavation hole 3 with concrete 6 is radially installed in broadening the lower end so that it may envelop a foundation 7 of an existing structural body (a). The upper and lower parts of the curved anchors 7 are fixedly connected to the foundation 7 or the lower part of the existing structural body (a) and the immovable basement 2, thereby protecting the existing structural body by relaxing and containing vertical and horizontal vibrations.

摘要： PURPOSE:To eliminate stress from locally being concentrated in part of a containment vessel body by transmitting force applied to shear lugs for constraining relative displacement between a containment vessel body and a containment vessel shell over the whole circumference of the containment vessel body through a ring reinforcement. CONSTITUTION:An annular ring reinforcement 16 is fixed on the outside part of a containment vessel body 14 so that the annular ring reinforcement 16 having width through which workers can pass may be approximately concentrically positioned for the containment vessel body 14, and a stopper 20 is set on the inside part of a containment vessel shell 15 surrounding the ring reinforcement 16 and the containment vessel body 14 so that the ring reinforcement 16 may be surrounded. In addition, shear lugs 21 are fixed on the ring reinforcement 16 so that they may be engaged with each stopper 20.

摘要： PURPOSE:To obtain reactor pressure vessel support equipment which enables improvement of the dimensional precision of a gap between a yoke and a bracket without relying on a method for regulation of the dimension of the gap between the yoke and the bracket by means of a thin plate shim. CONSTITUTION:Reactor pressure vessel support equipment has a reactor pressure vessel stabilizer bracket 20 fixed to a pressure vessel 1 and a yoke 6 fixed to a reactor shielding wall 3 and supporting the reactor pressure vessel stabilizer bracket 20. The reactor pressure vessel stabilizer bracket 20 is divided into three and fixed and the width of reactor pressure vessel stabilizer brackets 22 and 23 located at positions opposite to the yoke is selected so that a gap between them and the yoke 6 be a prescribed value.
