Abstract

PURPOSE: To improve the soundness of nuclear fuel element against vibration and the like by compressing the fuel pellet to axial direction with sealed tube type bellows spring where both ends having free expansion is sealed in an axial direction.
CONSTITUTION: Nuclear fuel element is configured by filling the fuel pellet within the clad tube 2 in a laminating manner, and compressing to support elasticly in an axial direction normally with sealed tube type bellows spring 15 for adsorbing expansion caused by the axial direction movement of fuel pellet 1 and heat within the reactor. Sealed tube bellows spring 15 is supported with stopper ring 6 to prevent whole body from moving in an axial direction. Sealed tube type bellows spring 15 is sealed with tag gas in the inner air space composing of sealed tube type bellows spring 15.
