Improved reconstitution and repair system for nuclear fuel rod assemblies.

摘要

Apparatus (100) for repairing and reconstituting a fuel rod asembly (110) in the spent fuel pool (111) of a nuclear power plant includes: a height-adjustable elevator and carriage assembly (200) for lifting and inverting a pair of fuel assemblies (110) with their bottom ends adjacent on another, a pulleyed length-adjustable rod handling tool (400) having a gripper (405) for gripping, lifting, lowering and ungripping a fuel rod, and a dual axis tool positioner (500) mountable over the bottom ends of the inverted, adjacent fuel assemblies. The tool positioner (500) includes a funnel-shaped tool guide (502) for receiving and positioning the gripper (405) of the rod handling tool (400). The apparatus is adjustable and may be used in spent fuel pools of substantially different dimensions and water levels.
