ている。これに従い建設工事を説明する。 A semi-underground nuclear power plant, especially the roof structure.
Construction work for power plants that employ SRC construction (steel frame/reinforced concrete construction, the same hereinafter), or construction consisting of a combination of RC construction (reinforced concrete construction, the same hereinafter) and temporary steel frames (hereinafter referred to as RC construction + temporary steel frame). As shown in Figure 5, the critical path of the process is as follows: Construction start - Excavation work - Rock inspection - Steel frame work - Matsu construction - PCV assembly work - Reactor building frame work - Steel truss wall work - Steel truss roof work - Reactor building overhead crane (R/B overhead crane) assembly - Reactor internal structure installation - RPV pressure resistance (RPC H/T) -
System pre-operation - Equipment/piping/electrical work - Fuel loading (F/L) - Start-up test - Start of operation (T/O). The construction work will be explained accordingly.
着工後の掘削工事は、原子炉建屋が岩盤定着を
必要とするため、最低岩盤レベル１までの掘削を
するが、岩盤レベル１が深い半地下式原子力発電
所となると、グランドレベル２から40ｍ〜50ｍも
の深さまで掘削する必要があり、掘削土量も200
万m3〜300万m3に達する。したがつて、大掘削工
事となり、工期も１年半〜２年位を費やす状況と
なつている。 Excavation work after the start of construction will be carried out to a minimum level of bedrock level 1, as the reactor building requires anchorage to the bedrock. However, in the case of a semi-underground nuclear power plant where bedrock level 1 is deep, the excavation work will be carried out at least 40m from ground level 2. It was necessary to excavate to a depth of 50 meters, and the amount of excavated soil was 200 meters.
reaching 3 million m3 to 3 million m3 . Therefore, it will be a major excavation work, and the construction period will take about one and a half to two years.
岩盤レベル１まで掘削し、岩盤露呈後岩盤検査
を受検する。岩盤検査合格後いよいよ建屋躯体工
事を開始する。 Excavate to bedrock level 1, and after exposing the bedrock, undergo a bedrock inspection. After passing the bedrock inspection, construction of the building frame will finally begin.
ここで建屋構造がSRC造（またはRC造＋仮設

排除する意味から、岩盤レベル１より原子炉建屋
躯体の軸組部における鉄骨３を先行組立する。こ

PCV組立工事において、PCV部材搬入口として
開閉が必要なため取外し可能なドームテント９を
設置してある。 If the building structure is SRC construction (or RC construction + temporary steel frame), the steel frame 3 in the framework of the reactor building frame will be pre-assembled from bedrock level 1 to eliminate the effects of wind, rain and bad winter weather. . The scope of this preliminary assembly is the basic reactor building 4 of the reactor building up to the operation floor 5, and the auxiliary building 6 up to the rooftop 7. Of the parts assembled by this preliminary assembly, the roof parts 5 and 7 and the outer wall 8 are protected with deck plates, tent materials, etc. In particular, the area of reactor building 4 will be described later.
In the PCV assembly work, a removable dome tent 9 is installed as it needs to be opened and closed as a PCV parts entrance.
このように建屋躯体軸組部の鉄骨３を先行組立

る。 In this way, the steel frame 3 of the building frame framework was pre-assembled, and the roof parts 5 and 7 and the outer wall 8 were cured, so the construction of the reactor building 4 frame was carried out before the operation floor 5 was constructed. Construction work can be carried out on the annex building 6 until the roof 7 is constructed, without being affected by weather conditions.

完了する。 In this way, construction of the building mat 10 will begin under environmental conditions that are not influenced by weather conditions, but since the steel frame 3 has been constructed in advance, the efficiency of transporting construction materials using a tower crane as in the past will be reduced. A monorail 11 with an overhang has been installed for loading and unloading. After the pine reinforcement work and pine concrete pouring are completed, the building frame work will gradually move on to wall work and floor work.
Then, as part of the critical path of construction work, we moved to the machinery side and began assembling the PCV12.
This PCV12 assembly work was divided into large blocks.
The PCV components will be lowered to the specified location using a large lifting machine, and then welded and assembled. At this time, the dome tent 9 mentioned above is removed and the PCV member is suspended. Pressure leakage test (PCV
L/T) and after passing, the weld line area is painted and completed.

する。 At this point, the critical path of the construction work shifts again to the building frame work, and the shield wall 13 that engages with the PCV 12 becomes critical and the building frame is erected. This building frame work will also be done indoors on the previously constructed steel frame 3, so it can be done in all weather conditions. However, the operation floor 5 and the wall work (not shown) on the operation floor 5 are carried out in the open air, and are therefore subject to the effects of bad weather in winter. Then, reinforcing bars and concrete are placed on the operation floor 5, permanent steel reinforcing bars are placed on the walls and roof, and roof concrete is placed to complete the building frame work.

事を完了する。 The next critical path for construction work will be the assembly of an overhead crane, and all future critical paths will be within the steel frame 3 building. After installation of the reactor internals and RPV H/T, system pre-operation, fuel loading (FL), and start-up tests will be carried out, progressing as shown in the schedule shown in Figure 5, and the construction work will be completed.

ている。 In other words, since the steel frame work will be carried out after the excavation work is completed, the excavation work itself will be carried out in the open air, which will be affected by wind, rain and bad weather in winter, reducing work efficiency and being unfavorable from a safety perspective. , the excavation period was becoming longer. In addition, the building frame work for the operation floor 5, which will serve as a temporary roof, and the walls installed on this floor will be carried out in the open air, so it will be affected by wind, rain and bad winter weather.
This is one of the causes of reduced work efficiency and lengthened construction periods.
