This invention relates to a pusher placed in a magazine for irradiated fuel elements which allows displacement thereof for the cutting operations. The pusher according to the invention allows the displacement of elements of small section in a magazine of large section. At the end of a cutting operation, the pusher applies its blank against the auxiliary holding clamp forming a continuous surface and the element is pushed by a blade, the body of the pusher being immobilized.

Pusher for magazine of irradiated fuel elements

Machine for removing the spacing wire (28) from a nuclear fuel rod (26). The rod (26) is moved through the central passages of first (10) and second (12) rotary parts. The first rotary part (10) has a portion in the form of a milling cutter (30) for detaching the welding spots from the wire (28) on the rod (26). As the rod advances, the wire (26) passes into the holes (32) of the first rotary part (10) and the holes (34) of the second part (12). As these two parts rotate at different speeds, the wire (28) is cut by shearing. Application to the reprocessing of the irradiated fuels of fast neutron nuclear reactors.
