Abstract
Method and apparatus for adjusting the level of fuel rods in a fuel assembly which includes a tool having an end insertable between a fuel assembly nozzle plate and the exposed ends of fuel rods. The insertable end of the tool includes stationary and movable plates, the movable plate having a portion which rests on flanges in a forked end of the stationary plate while the other end of said movable plate is bent in a manner such that it lies above the stationary plate. A pair of gears are located in the space defined by the spaced ends of said plates, and screw threaded shafts extend through threaded openings in the movable plate and into gears located in the space between the ends of the plates, so that when one of the shafts is rotated, the force transmitted through said gears causes the other shaft to rotate and the coaction of both threaded shafts thus causes the movable plate to move in a direction away from the stationary plate, and in so doing, cause the fuel rod in contact with the movable plate to be moved in an axial direction and into a position where the end thereof lies in the same plane as the ends of other fuel rods in the assembly.
