ABSTRACT:
A system and method for handling nuclear fuel in which a consolidation stage (26), including a disassembly station (60), an interim transfer station (62) and a consolidation station (64), and a multiple rod pulling tool (78) and interim fuel transfer canister (86) are employed to remove fuel rods (42) from two fuel assemblies (32) and consolidate them into one storage box (96). A key feature of the disclosure is the alignment of the transfer canister (86) over the box (96) such that the canister base (92) with the weight of the consolidated rods, is released and lowered into a new position as the base of the storage box (96). A duel elevator arrangement (108, 110) is disclosed for moving the base (29) and box (96) to transfer the rods therebetween.
