Abstract (en)
To carry out interventions, in particular for control and maintenance, inside heat exchangers such as steam generators used to equip nuclear power stations, an apparatus is proposed, which comprises an articulated arm formed by at least two rigid segments (24a, 24b) which are articulated to one another about an axis (A), and two plates (30a, 30b) mounted at the ends of the articulated arm by means of two wrists (28a, 28b) which each permit two rotations about two orthogonal axes (B, C), one of which (B) is parallel to the axis (A) and the other of which (C) is perpendicular to the surface (31a, 31b) of the corresponding plate. Each plate (30a, 30b) supports means of attachment (32) which are capable of coming into engagement in the perforations (20a) of a tube plate (12) of the exchanger, and a support (34) for an intervention tool. <IMAGE>
