Abstract

PURPOSE: To improve resistance against earthquakes by pivoting at least a part of each sheath on adjacent stationary plates and fitting sheathes in the adjacent tie rods or other part of the sheathes.
CONSTITUTION: A fuel assembly 9 comes in contact with sheathes 2A disposed at right angles to the direction of vibration of the fuel assembly 9 and presses the control rod 13 when the fuel assembly 2A is vibrated by earthquake. A sheath disposed in the direction of vibration will not be deformed as relative motion of the sheath components 20 and 21 absorb the compression of the fuel assembly 9 because each sheath is constituted of relatively movable components 20 and 21, therefore, only the tie rod is bent.
