Abstract
In a BWR fuel assembly, fuel rod spacers are disposed in desired axial positions along the fuel rods by a plurality of yieldably-resilient arcuate-shaped leaf springs. Some of the springs are disposed between an interior side of the fuel assembly outer channel and exterior sides of the spacers, whereas others are disposed between an exterior side of a central water cross and the exterior sides of the spacers. The springs thus contact the spacers and either the channel or water cross and exert sufficient contacting force thereon to maintain the spacers substantially stationary in the desired axial positions along the fuel rods. The springs extend generally parallel to the axial direction of the fuel rods and are spaced apart from one another in a direction generally transverse to such fuel rod axial direction. Each spring can be fixedly attached at one end to the spacer or clipped on an edge of the spacer.
