As shown in Figure 1, the lining installation method is a post-lining method in which the lining plate is welded to the base hardware buried in the concrete, and it depends on the building concrete placement process. Therefore, R/W lining installation is required in the reactor construction process.
This work is performed in parallel with the equipment installation work inside the RPV, and each work becomes a hindrance, resulting in a decline in work efficiency.

ることを特徴とする。 In order to achieve this objective, the R/W lining installation method of the present invention involves assembling the entire R/W lining at a location other than the installation site, and attaching it to the lower flange of the reactor containment vessel (hereinafter abbreviated as PCV) and the shield. The present invention is characterized in that a plurality of horizontal supports are temporarily installed radially from the flange portion using wall reinforcing bar bundles, and the R/W lining is installed on the support in the reactor pressure vessel.

器据付作業前に完了することが出来る。 An embodiment of the present invention will be described below with reference to FIGS. 2 to 5. In Figure 2, the reactor building is PCV1,
PCV flange 2 and PCV lower flange 3 have been installed. Also, shield wall 20,
Concrete has been placed up to 22, and shield wall reinforcing steel bundles 21 have been placed beyond the PCV flange 2. The R/W large panel block 30 is installed in advance at a location different from the installation location, with a lining plate 31, base hardware 32,
It is assembled into one. The R/W large panel block installation support 34, as shown in Figures 2 to 5, includes a PCV lower flange 3, a sleeper 39, a shield wall reinforcing bar bundle 21, and a vertical support 36 on top.
A plurality of horizontal supports 35 are installed radially from the PCV lower flange 3. Furthermore, horizontal support 35, comrade, steady support 37,3
8, is connected and configured. For this reason, the R/W large panel block installation support 34 is restricted in its planar direction. Moreover, the installation level of the above-mentioned installation support 34 is the same as that of the above-mentioned sleeper 39 and the vertical support 3.
It can be adjusted by adjusting the height of 6. The configured R/W large panel block installation support 34,
After arranging the shield wall rebar bundle 20,
The aforementioned PCV lower flange 3 and shield wall reinforcing bar bundle 20 are temporarily installed on top, and the R/W large panel block 30 is suspended and welded thereon. As described above, the R/W lining installation work can be completed before the reactor pressure vessel installation work.

に、建設期間短縮により建設費が安価となり経済
性に優れている。 According to the present invention, not only can the R/W lining installation work time be shortened, but it can also be completed before the reactor pressure vessel installation work, so the installation work of individual equipment inside the reactor pressure vessel after the reactor pressure vessel can be completed. Since the installation work can be carried out safely and smoothly, the installation work, which previously took 9.5 months, can be shortened to about 8 months, and the construction period is shortened, making construction costs cheaper and more economical. Excellent.
