Abstract
The device comprises a pole fastened to a handling and lifting apparatus arranged above the pool in which the fuel assembly is placed under water. The pole has at least one lower end part (32), the diameter of which is less than the inside diameter of the blocking sleeve (25). This part (32) is pierced with a central bore (40) and with at least two radial orifices (56), in each of which is located a retention claw (57). A rod (41) sliding in the axial bore (40) makes it possible to control the extraction of the claws. The vertical movement of the pole makes it possible to extract the blocking sleeve (25).
