するようにしたものである。 FIG. 1 shows a conventional example of a method for constructing a reactor containment vessel. In this construction method, a reactor containment vessel 2 and a pedestal 3 are constructed on a foundation 1, a diaphragm floor 5 is formed by supporting the pedestal 3 and a column support 4 erected on the foundation 1, and then While parts are carried in through the opening 2a provided in the upper part of the reactor containment vessel 2, a frame-shaped pipe whip is supported by the diaphragm floor 5 and temporary supports 6 erected on the diaphragm floor 5. After constructing the structure 7 and further carrying the piping 8 into the pipe whip structure 7 from the unmarked direction in FIG. 1 and fixing the piping 8 to the pipe whip structure 7, The reactor shielding wall 9 divided vertically is carried into the reactor containment vessel 2 through the opening 2a, and is pulled horizontally by a winch 10 or the like.
As shown by the chain line in FIG. 1, the temporary support 6 is installed on a pedestal 3, and after the pipe whip structure 7 is supported by the shielding wall 9, the temporary support 6 is removed.

る。 However, in the conventional method, it is necessary to divide the reactor shielding wall 9 to such an extent that it can be carried in through the opening 2a, so there is a problem that a large number of man-hours are required for installation. Also,
Since the reactor shielding wall 9 has a large weight in order to obtain a predetermined radiation shielding ability, there is a problem in that a great deal of labor is required to pull it horizontally. Furthermore, the pipe whip structure 7
There is a problem in that temporary supports 6 must be used to install the reactor shielding wall 9 in advance of the reactor shielding wall 9.

ある。 The present invention was proposed in consideration of the above-mentioned circumstances, and consists of dividing the internal structure of the vessel consisting of a pipe whip structure and piping into blocks in advance, and using the internal structure of the vessel as a shield for the reactor. The purpose is to shorten the construction period of the reactor containment vessel by constructing the reactor containment vessel so as to cover the internal structure of the reactor vessel and the reactor shielding wall after installing the reactor containment vessel by supporting it on the wall and the diaphragm floor. That is.

とができるという効果を奏する。 According to the above construction method, the reactor shielding wall 9 and the internal vessel structure 11 are installed before the upper wall 2c of the reactor containment vessel 2 is constructed. Container internal structure 11
For example, the reactor shielding wall 9 and the internal structure of the vessel 1 can be divided into large blocks to reduce the number of installation steps within the capacity of the crane used for installation.
1 can be easily transported to a predetermined location. Furthermore, by assembling the piping 8 in the pipe whip structure 7 in advance, it becomes possible to install the reactor shielding wall 9 prior to installing the vessel internal structure 11. Thing 11
There is no need to use temporary supports during installation. Furthermore, temporary scaffolding for constructing the reactor containment vessel can be taken from the pipe whip structure, eliminating the need to take scaffolding from the reactor containment vessel as in the past. Further, the scaffold can be used not only temporarily but also permanently as a permanent platform. And, due to the synergistic effect of each of the above effects,
This has the effect of shortening the construction period of the reactor containment vessel as much as possible.
