現地据付工法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for on-site installation of a MAr (K-1 type reactor containment truss section) of a boiling water type nuclear power generation facility among nuclear power generation atomic couplants.

を必要とし、ていた。Conventionally, the on-site installation of the truss section of the MARK-1 reactor containment vessel was carried out by assembling each side of the hexagonal block at a factory or on-site assembly site, and then hoisting it to the official installation site. However, this method lacks workability because groove alignment and welding are performed at the corners of the polygonal ring of the torus (1). Due to the inability to set up support, it required a lot of construction time.

をすることにある。The object of the present invention is to construct a hexagonal torus, -0.5 on both sides of the edge
By blocking the edges on the ground at the factory or site,
Conditions for corner groove alignment and welding are improved, and quality can be stabilized. Furthermore, since the torus support can be installed either at the factory or on the ground at the site, the on-site installation period can be significantly shortened.

ラスサポートも取付けだ大型ブロック化工法である。The present invention is a method for welding the corners of polygonal rings, which are the most difficult to weld, either in a factory or at a site with good ground conditions, to stabilize quality, and to significantly shorten the on-site installation period.
This is a large block construction method in which a hexagonal torus is made into blocks of 0.5 sides on each side at the factory or on the ground at the site, and the internal structure and torus support are also attached.

The dry well and torus are connected by a vent pipe 3, and if an accident such as damage to reactor cooling water pipes occurs in the dry well, the steam will be guided into the torus 2 through the vent pipe 3 and This structure suppresses the pressure in the dry well by cooling and condensing the water stored inside.

るものである。As shown in the drawing, the torus has a hexagonal polygonal ring, supporting the torus 2-1, a vent pipe 3 for guiding steam in the dry well in the event of an accident, and a downcomer header 4 and a downcomer connected to it. Consists of pipes. Conventionally, on-site construction of this torus was carried out by assembling each side of the hexagon at the factory or on the ground at the site, and then hoisting it to the installation location, but with this construction method, the construction method was carried out by assembling each side of the hexagon at the factory or on the ground at the site, and then suspending it to the installation location. Bevel alignment and welding must be carried out at the installation site, and the torus support cannot be set until after the main corner welding is completed, which has the disadvantage of requiring a long process. The present invention has been made in view of these drawbacks, by changing the assembly range on the ground at the factory or at the site, and for a hexagonal torus, 0.5 sides on both sides of one side are set as the assembly range at the factory or at the site. The welding at the installation site is carried out at the middle of the cylindrical part shown in 2b.

安定化及び現地据付工期の大幅短縮の効果がある。FIG. 3 shows a view of hoisting the torus according to the invention to the installation site. According to this method, torus body welding on-site involves welding the middle of the cylindrical part, which is different from welding the corner parts, and is relatively simple, making it possible to employ automatic welding, etc. In addition, the support supports of this torus are installed at each corner of the hexagon, but according to this method, the welding of the corner parts is completed at the factory or on-site ground, so the support supports can also be installed at the factory or on-site ground. This has the effect of stabilizing quality and significantly shortening the on-site installation period.
