FIG. 1 is a partially sectional side view showing the relationship between a reactor building and a reactor containment vessel of a nuclear power plant.

Torus 8 will be brought in. After that, the torus 8 and the scaffolding 9 for assembly are installed, but the distance between the torus 8 and the underground wall 3 is very narrow, about 600 to 700 mm, due to the structure of the building, so it is impossible to install the scaffolding that is normally installed. As it is possible, torus 8 is being assembled using simple scaffolding made of pipes, etc. Then, the outer surface of the reactor containment vessel 7 is painted, and the shield wall 1 is painted.

因となつている。 In other words, due to the procedure of transporting the torus 8 of the reactor containment vessel 7 after the basement wall 3 of the reactor building 1 is completed, the time to start assembling the torus 8 is extremely delayed, and therefore the critical path for reactor containment vessel assembly is delayed. It is becoming. In addition, due to the walls, there are severe restrictions on bringing in and working on machinery. Furthermore, the distance between the torus 8 and the underground wall 3 is narrow, making it difficult to carry out parallel work, and the mechanical and construction work must be completed separately, making it extremely difficult to standardize the amount of work.
Furthermore, it was necessary to replace the scaffolding with the building side or the machinery side, and since it was a pipe scaffolding, there were also safety issues. As a result, the construction of the underground wall 3 and the installation and assembly of the torus 8 of the containment vessel become critical paths in the overall construction period of the nuclear power plant, and are the biggest reason for the long construction period of the entire reactor building.

This is a construction method for a reactor building in which the construction work of the underground wall 3 and ceiling 11 of the reactor building is to be carried out.

As shown in Fig. 3, first, after the pine slab 2 of the reactor building 1 is completed, the tower crane 6
As shown in the figure, the torus 8, the steel frame formwork 12 of the underground wall 3, the steel frame support material 13, and the torus upper floor steel deck plate 1 are prepared in advance at the above-ground assembly site in the factory and on-site.
A torus 8 which is integrated with 1 is hung onto a mat 2. Once the lifting is completed, the installation and assembly of the torus 8 is started, and the construction of the underground wall 3, on which the steel formwork 12 has already been set, is carried out in parallel on the torus room 5 side. basement wall 3
After the construction of the torus room is completed, the construction of the upper part of the torus room where the steel deck plate 11 is installed will be continued. After the installation of torus 8 and reactor containment vessel 7 is completed, a total leakage test is conducted.
After the exterior painting is completed, construction of the shield wall 10 is started and the reactor building 1 is completed.

出来る。 As explained above, according to the method of constructing a reactor building by installing a reactor containment vessel and a torus according to the present invention, immediately after the concrete pouring and curing of the pine slab of the reactor building, the torus is transported and assembled, and the underground wall construction work can begin.
In addition, since the construction work on the machinery side and the building side can be carried out in parallel, the construction period for assembling the underground walls and torus, which is a critical path in the construction process of a nuclear power plant with a torus-type reactor containment vessel, can be shortened. , it is possible to significantly shorten the overall construction period of a nuclear power plant. Furthermore, when transporting the torus, the steel formwork for underground walls and ceilings, as well as the steel formwork support materials, are integrated and suspended at the same time, greatly improving work efficiency.

短縮させることができる。 Furthermore, it is no longer necessary to set up construction scaffolding for assembling the formwork on the side of the basement wall facing the torus room that forms the side of the torus room, which was conventionally used, and scaffolding for assembling the torus, improving safety. Also, the time required for assembling and dismantling the scaffolding described above can be shortened.

作用効果には影響がない。 In addition, in the present invention, scaffolding is used to assemble each suspended torus, and furthermore, scaffolding is used at a position facing the torus room during concrete pouring of the basement wall, which is performed in parallel with this assembly work. It will be done. However, since the scaffolding used for these works is used after the torus has been suspended, the construction period is not restricted and the effects of the present invention are not affected.
これらの種々の効果の総合により原子力発電所
建設工期の大巾な短縮と建設費用の節約は著しい
