合体。 In nuclear fuel assemblies for boiling water reactors,
It has fuel rods of normal length and shorter fuel rods with both ends fixed to the upper and lower tie plates, respectively, and both are supported at regular intervals by spacers arranged at multiple locations in the axial direction, and the spacers are Among the springs that hold the fuel rods, the holding force of all the springs that hold the short fuel rod, the holding force of the springs that hold only both ends of the short fuel rod, or the holding force of only the top end of the short fuel rod. A nuclear fuel assembly characterized in that the holding force of a holding spring is higher than the holding force of a fuel rod of normal length.
