ペースプレート５の端を嵌め込んで溶接連結しである。The reactor containment vessel stabilizer stably supports the reactor pressure vessel within the containment vessel, and is provided specifically for the purpose of preventing the reactor pressure vessel from shaking during an earthquake. Conventionally, reactor containment vessel stabilizers are generally
As shown in FIGS. 1 and 2, a shag 4 installed on the inner periphery of the reactor containment vessel 1 and a stabilizer installed on the upper periphery of the reactor shielding wall 3 surrounding the reactor pressure vessel 2. It consists of a pace plate 5 and a stabilizer truss 6 that connects the two. Stabilizer truss 6
A split groove is formed at the end of the recess, into which the end of the stabilizer pace plate 5 is fitted and connected by welding.

けるのに多大の労力と時間を要する等の欠点があった。By the way, since the reactor containment vessel 1 and the reactor shielding wall 3 are manufactured and installed independently, the manufacturing and installation of both may be subject to errors, and the heights of the shield lug 4 and stabilizer pace grate 5 may differ. There are cases where this happens. In such a case, the above-mentioned conventional connection structure has the disadvantage that it takes a great deal of effort and time to take out and install the stabilizer truss 6 that connects the two at the same level.

合せを可能とするものである。The reactor containment vessel stabilizer of the present invention, which was made with the objective of , the surface of the flange is arranged parallel to and opposite to the vertical 7 flange surfaces of the stabilizer space plate, so that the level between the space plate and the stabilizer pace plate is adjusted. M
By compensating by adjusting the mounting position of the stabilizer truss on the flange surface of the stabilizer base plate, it is possible to level the stabilizer truss during installation.
以下、本発明に係る原子炉格納容器スタビライザの一実
施例を第３図及び第４図により説明する。Hereinafter, one embodiment of the reactor containment vessel stabilizer according to the present invention will be described with reference to FIGS. 3 and 4.

る。Sharrags 4 are installed at eight locations on the inner circumference of the reactor containment vessel 1, and stabilizer pace plates 5 are installed at eight locations on the upper circumference of the reactor shielding wall 3 surrounding the reactor pressure vessel 2. A reactor containment vessel stabilizer is constructed from the stabilizer truss 6 that connects the two. At the end of the stabilizer base grate 5, a franchise 9 having a vertical and relatively wide surface with a chevron-shaped cross section is formed to which the stabilizer truss 6 is attached. A corresponding flange 8 is formed at °C. The opposing surfaces of the flanges 7 and 8 are arranged parallel to each other, and the length of the stabilizer truss 6 is adjusted according to the distance between these opposing surfaces. It is attached to the opposing surfaces of 7 and 8 by means such as welding.

できる。According to the structure of the above embodiment, even if there is a discrepancy in the mounting level between the stabilizer base grate 5 and the shag 4, the mounting of the end of the stabilizer truss 6 to the flange 7 of the stabilizer pace plate will be performed at the appropriate position. The truss 6 is formed by adjusting the plane of the flange 7.
Since it is possible to place the stabilizer truss flat, it is extremely easy to level it, and when installing the stabilizer truss 6, the processing required is to align the inner surface of the column between the 7 langes 8 of the shag 4 and the 7 langes 7 of the stabilizer pace plate 5. All you need to do is complete WIIJ adjustment of the length of the truss 6 according to the actual measured distance.
Sufficient strength can be maintained even against the load during an earthquake.
