Abstract (en)

[origin: EP0648974A1] The invention relates to a device for radial holding of the wrapper of the tube bundle and the support plates of a steam generator, consisting of stops penetrating the wall of the bundle wrapper and fixed to this wall at the support plates, the stops being distributed at the periphery of each support plate in order radially to separate the bundle wrapper from the pressure casing of the steam generator. Each stop comprises a first part (31) fixed onto the bundle wrapper (6), placed in contact with the internal face of the pressure casing (1), and a second part (32) exerting a rigid holding constraint on the support plate via elastic means. <IMAGE>
