<p>The invention relates to a machine that includes two rollers (3) for imparting an oval shape to a nuclear fuel sheath (16) in order to crush the content thereof so that said content can easily be removed even when the pellets have been arranged within the sheath with little clearance. The opposite inclinations of the rollers (3) promote the automatic advance of the sheaths (16). The opening and the inclination of the sheaths result in the discharge of the crushed fuel. The rollers are biconical with an inlet portion having an increasing diameter and an outlet portion having a decreasing diameter in order to apply a sufficiently oval shape for crushing the fuel while restoring the circular symmetry of the sheath at the machine outlet for facilitating the flow of debris.</p> |
