Abstract

Improvements in thermal insulation devices of pre-compressed concrete tanks for nuclear reactors, of resistance to the pressure of a vaporizable fluid contained in the interior of the tank or tank in two phases separated by an interface, at least two families of voyages being organized in the parts lower and upper part of the container for the positioning of inlet ducts of fluid in liquid state and of exit of fluid in gaseous state, characterized in that they comprise two ferrules arranged respectively in the lower and upper parts of the container, the upper ferrule being closed by a lid and the ferrules having different diameters, ferrules that are coated with a metallic heat insulator and delimiting between the vaporizable fluid and the internal wall of the container a chamber filled with fluid in liquid phase up to the height of the fluid-vapor interface of the fluid and filled with gas above the level, constituting the coating of the ferrules a cold fluid liquid gasket; means by means of which the ferrules are each supported by the container at the height of at least three of the crossings of the same family, these means permitting the radial dilation of the ferrules at the height of these traverses; and watertight means arranged at the height of the crossings capable of absorbing the radial expansion of the ferrules.
