ABSTRACT OF THE DISCLOSURE The invention relates to a steam generator incor- porating a tube bundle arranged in a bundle casing. The bundle casing incorporates openings in its wall, each corresponding to a supporting component, openings along the edge of which are fixed sleeves projecting radially into the space between the casing and the outer wall of the heat exchanger. Each of the supporting components incorporates two cylindrical parts situated in extension of one another, a large-diameter part welded by its side surface inside the sleeve and a small-diameter part intended to come to bear on the casing. Wedges are inserted between the part of the supporting component and a spacer plate of the heat exchanger. The invention applies, in particular, to steam generators of pressurized water nuclear reactors.
