摘要:
A fuel assembly for a boiling water reactor, comprises fuel rods (2), a tie plate (3), a handle device (4), and at least two water rods (7) attached to the tie plate and to the handle device. A plurality of spacers (8a, 8b), define first passages (8') for some of the fuel rods, and second passages (8") for the water rods. Each water rod comprises a tube part (7a) attached to the tie plate, and a solid part (7b) attached to the handle device. The tube part permits a flow of coolant. The spacers comprise primary spacers (8a) and a secondary spacer (8b). The primary spacers are attached to the tube parts. The tie plate, the water rods, the primary spacers and the handle device form a support structure carrying the weight of the fuel rods. The secondary spacer is positioned at the solid part of the respective water rod.
