| 摘要 |
A heat insulating material mounting structure of a steam generator of the present invention, for preventing the thermal expansion deformation of a sliding base below the steam generator by blocking the heat transferred from the steam generator provided in a nuclear reactor (1), comprises: a heat insulating material disposed along the lower surface of a stay cylinder of the steam generator and the upper inner surface of a skirt support; and a support plate that is disposed along the connection portion between the stay cylinder and the skirt support and includes a plurality of pieces for closely fixing the heat insulating material to the lower surface of the stay cylinder with a plurality of fixing bolts that pass through the skirt support from the inside to the outside thereof, thereby preventing the deflection of the heat insulating material, which is caused by vibration while the nuclear reactor (1) is being operated. |
