Abstract
The wedging members (15) are introduced between the components (4) at a temperature t0 substantially different from the working temperature ts of the stream generator. The wedging member (15) comprise at least one portion (22) of shape memory alloy having a first configuration at the temperature t0 and a second configuration at the temperature ts, such that the wedging parts (15) have an initial transverse dimension less than the width of the separation spaces between the components (4) at the temperature t0, and a transverse dimension substantially greater than the initial dimension at the temperature ts. The components are wedged automatically at the moment when the installation is brought to the working temperature. The invention is applicable in particular to the anti-vibratory bars disposed in the top part or chignon of a steam generator of a pressurized water nuclear reactor.
