Abstract

Improvements introduced into a protective structure of a nuclear reactor tank, of the type that includes a vertical metallic tank of pressure resistance, elongated, and closed on its upper part by a cover, carrying said tub connection junctions to pipes of the refrigerant fluid circuit, characterized by comprising a prestressed concrete box, which surrounds the side wall of said tank and its bottom, and which carries prestressing cables, said box having a height greater than the height of said tank said drawer comprising holes for the passage of the pipes of the refrigerant fluid circuit and an upper flange, and a crown that rests on the periphery of the lid of said reactor and made integral therewith, said crown being applied to said lid by means of organs clamping mechanics, which work in compression and also rest on the inner face of a piece of annular shape, applied each on the upper face of said drawer, and in which the ends of some of the prestressing cables are anchored.
