題点があった。On the other hand, storage equipment other than the main steam pipe 6 in the turbine building 2,
That is, all equipment such as the turbine 14 has a seismic class of B class or C class. Therefore, the turbine building 2 simply installs the main steam pipe 6,
It means that it is necessary to maintain seismic A-class function as a whole. For this reason, the constituent parts of the turbine building 2 which are originally supposed to be able to maintain the B class function are also maintained in the A class function. In this way, maintaining the structure of the building in the A class function requires making the structure more complicated and robust than maintaining the B class function, and therefore the amount of both the reinforcing bar and concrete is considerably large. There was a problem that it would increase.
