Because the distance between the torus 2 and the l! Torus 2 must be brought in after Torus 4 is completed and 1 scaffold is removed.
Installation work cannot be done. Therefore, even if the assembly of the reactor containment vessel 3 has been completed, the pressure test of the reactor containment vessel 3 cannot be carried out until the torus chamber wall 6 is completed and the torus 2 is delivered and installed. Therefore, the work from the construction of the wall 6 of the torus room to the carrying-in and installation of the torus 2 constitutes a critical path for the entire construction work, and is a factor that prolongs the construction period of the nuclear power plant.

The assembly of the Torus 2 and the transport and installation of Torus 2 will be carried out in parallel. Next, a pressure test is carried out on the reactor containment vessel 3, and upon completion of the pressure test, the DI sub-reactor containment vessel 3 is painted. When the painting is completed, concrete 8 is filled in the lower space of the reactor containment vessel 3, and an underground shield wall (■) 9 is constructed. After this, construction will be carried out in order: floor 1o on the first floor, wall 11 on the first floor, underground shield wall 12 on the first floor, and floor 13 on the second floor.
