Abstract
A thimble screw alignment plate is disclosed herein that greatly facilitates the removal and reinstallation of the bottom nozzle of a fuel assembly. The screw alignment plate includes a plurality of bores registrable with the screw holes of a bottom nozzle, and a resilient sleeve mounted over each bore for receiving, retaining and aligning the threaded end of a screw with each such screw hole. The alignment plate is particularly adapted for use in an overall fuel assembly repair and reconstitution system, and greatly expedites the removal of bottom nozzles whose feet include flanges or gussets that obstruct access to one or more of the thimble screws that connect the bottom nozzle to the support skeleton of the fuel assembly.
