ABSTRACT:
The safety device consists of doubling a first reel (4) equipped with an operating cable (11) from a carriage (24) for nuclear fuel elements is suspended, by a second reel (5) equipped with an emergency cable (12) connected with the carriage (24) and following the displacement of the carriage in a synchronous manner with the aid of a set of cog-wheels (6 and 7) joined respectively with the reels (4 and 5) by means of reducing gears (2 and 3) and connected with each other by a notched belt (8).
To attenuate the impact in case of a rupture of the operating cable (11) and the loading of the emergency cable (12), the carriage (24) is equipped with an attenuating system (22) and an elastic connecting system (20).
