止用櫛形治具。[Claims for Utility Model Registration] 1. A large number of fuel rods arranged in parallel in the length direction are supported by a plurality of support grids, the upper part is connected to the upper tie plate via a rod spring, and the lower part is connected to the lower tie plate. The jig is inserted between the rod springs of the fuel assembly connected and fixed to the rod springs to prevent the movement of the fuel rods, and is shaped like a comb and has a comb portion inserted between the rod springs. The pitch of the comb portion is the same as that of the fuel rod, the interval between the combs is approximately the same as the outer diameter of the rod spring, and the width of the comb portion is approximately equal to the installation length of the rod spring, and the comb length is approximately the same as the outer diameter of the rod spring. A comb-shaped jig for preventing fuel rod movement, characterized in that the length is approximately the same as the length of a cross section of a fuel assembly. 2. The comb-shaped jig for preventing movement of fuel rods according to claim 1, wherein the material of the comb-shaped jig is at least one selected from metal, ceramics, wood, and hard synthetic resin. 3. The comb-shaped jig for preventing movement of fuel rods according to claim 2, wherein the material of the comb-shaped jig is hard polyethylene.
