[Claims for Utility Model Registration] 1. In a fuel bundle for a boiling water reactor in which a plurality of fuel rods are arranged and supported in a square lattice shape by a plurality of fuel spacers, the upper and lower ends of the fuel rods are rigidly fixed. A fuel bundle characterized in that a part of a rib support structure supporting from four directions in the center of at least one of the upper and lower tie plates which are supported or simply supported is removed. 2. The fuel bundle according to claim 1, characterized in that the shape of the tie plate consisting of the boss portion and ribs is symmetrical with respect to the control rod position. 3 In claim 1 of the utility model registration claim, the width of the rib portion supporting the boss portion is narrowed, and the bending rigidity of the rib portion decreases by the narrowed amount, and the height of the rib is increased to a level equal to or higher than before narrowing. A fuel bundle featuring:
