PURPOSE:To obtain a structure which will not bring buckling at the time of an earthquake by providing a tank main body installed in a pit chamber and a pot part for seal provided on an upper outside surface of it. CONSTITUTION:A tank main body 1 is mounted and fixed on a base seat 3 for a floor part in a pit chamber 2, and an upper end aperture of the chamber 2 is closed with a roof part 4. A circular pot part 6 for seal where liquid metal 5 for seal is filled is provided on an upper outside surface of the main body 1. A partition cylinder 7 is provided immersed at a lower end part at a lower positron in time metal 5 in the pot part 6 and suspended from the underside surface of the roof part 5. A cover gas space 8 in the main body 1 and a pit chamber gas space 9 in the chamber 2 are separated by the cylinder 7, so cover gas in the main body 1 is prohibited from flowing into the chamber 2, and gas in the chamber 2 from flowing into the main body 1. For the liquid metal, liquid metal sodium 10, for example, is contained in the main body 1, and a steam generator 11 is provided immersed in the sodium 10 at a lower part and fixed at the roof part 4 at art upper part. A thinner structure less likely to produce a thermal stress can thus be achieved, and buckling at the time of an earthquake can be prevented.
