Abstract
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.
