ABSTRACT:
An element (18) of elongate form is fastened onto the tube support plate (8a) of the steam generator nearest the bent parts (10c, 10"c, 10'"c) of the tubes (10) of the bundle, in a central free zone of the bundle, in line with the small bends (10"c) of the tubes of the bundle. Anti-vibration bars (15) of a set of bars which are intended to be placed between any two adjacent rows (20) of the bundle of tubes are fastened by their internal end onto a dovetail piece (16) which is attached to the elongate element (18). All the anti-vibration bars (15) intended to come into a space contained between two successive rows (20) of the bundle of the heat exchanger are thus fitted in a single operation. The invention applies in particular to steam generators of pressurized water nuclear reactors.
