ABSTRACT:
A heat exchanger, in particular for a nuclear reactor steam generator, comprising a U-tube bundle and a stabilizing system composed of anti-vibration bars inserted between the tubes of the bundle in the upper tube U-bend region. The anti-vibration bars have portions that protrude from the tube bend region, and the stabilizing system comprises elements which connect the aligned portions of the ends of the anti-vibration bars and are composed of a comb with slots designed to receive the ends of the anti-vibration bars, and a comb cover attached with fastening means. All the connecting elements are attached to supports that are joined to the bundle wrapper, while allowing limited movement of the set of anti-vibration bars and connecting elements.
