PROBLEM TO BE SOLVED: To provide a system for aligning a nuclear fuel bundle (1100) and handling selected fuel rods within the fuel bundle. SOLUTION: A fuel bundle includes water rods, full-length and part-length fuel rods, and each fuel spacer has a plurality of cells, corresponding to the fuel rods and the water rods. The system includes a fuel bundle alignment assembly (200) for making the fuel rods and water align, a fuel rod grapple tool (400), to extract selected part-length rods from the fuel bundle, and a fuel rod guide block (300), slidable onto the top end of the fuel bundle for protecting the uppermost fuel spacer of the fuel bundle, making the fuel rods align individual cells of all the fuel spacers in the fuel bundle.
