ABSTRACT:
A cutter guide fixture for use in removing a top nozzle from the guide thimbles of a fuel assembly includes upper and lower plates coupled to one another for movement of the upper plate relative to the lower plate between upper and lower positions. The plates include aligned pairs of holes within which are mounted a plurality of cutters such that the cutting elements of the cutters are disposed in a common cutting plane. A pair of expansion locking pins are provided at a pair of diagonal corners of the lower plate for releasably attaching the fixture to the top nozzle and positioning the cutters in general alignment with a plurality of passageways defined in the adapter plate of the top nozzle and with a plurality of hollow upper end portions of the guide thimbles inserted and attached in the passageways. A threaded shaft interconnects the upper and lower plate such that rotation of the shaft in either of two directions will move the upper plate between its upper and lower positions and move the cutters between raised positions withdrawn from the passageways and inserted positions where their cutting elements are disposed in the passageways and hollow upper end portions of the guide thimbles.
