ABSTRACT:
A cutter for cutting, in stages, irradiated bundles of nuclear fuel rods, pecially from pressurized-water or boiling-water reactors. The cutter includes a feed channel associated with transverse and longitudinal feed devices for the rod bundle. A cutter housing is arranged at the mouth of the channel. A cutter carriage can be moved at right angles to the feed channel and is provided with a cutter blade; a fixed counter-blade cooperates with this cutter blade; a rod bundle clamping mechanism is located ahead of the cutting plane and is provided with two alternately actuatable clamping jaws. The cutter carriages, the cutting blade, the counter-blade, and the two clamping jaws can be removed and replaced. The transporting, clamping, and cutting devices are respectively provided with their own drive unit. The feed device has a guide channel formed by a fixed table plate which is provided with a guide bar mounted thereon, by a removable supporting beam which is provided with a closure slide, and by a second removable supporting beam. An interchangeable guide rail is provided for the cutter carriage.
