ABSTRACT:
The device comprises an elongate transmission member (30) which can be moved inside the steam generator tube by pulling and pushing. The elongate member (30) comprises a central metal cable (31), a flexible peripheral sheath (32) and a plurality of annular members (33) which are not connected together and are threaded in sequence onto the flexible sheath (32). A clearance (34) corresponding to the difference in length between the sheath (32) and the total length of the members (33) when they are placed end to end allows the member (30) to be moved inside the tube by pushing without the application of great force. In particular, the device enables heating elements to be inserted and positioned in the curved parts of the tbes of the bundle of a steam generator of a pressurized-water nuclear reactor.
