Abstract: A method of making a fuel channel (10) for a fuel assembly (8) for a nuclear power boiling water reactor comprises: providing at least one first sheet (11) of a Zr-based material of a first thickness (T), providing at least one second sheet (12) of a Zr-based material of a second thickness (t), which is less than said first thickness (T), assembling at least said at least one first sheet (11) and said at least one second sheet (12), such that a fuel channel (10) is formed and such that said at least one first sheet (11) forms a lower part (LP) of the fuel channel (10) and such that said at least one second sheet (12) forms a higher part (HP) of the fuel channel (10) and such that said lower part (LP) is joined with said higher part (HP), wherein said lower part (LP) constitutes 20-75% of the length (L) of the fuel channel (10). The invention also concerns a fuel channel (10) and a fuel assembly (8).

Abstract: A fuel assembly (1) for a boiling water reactor comprising fuel rods (3), two or three water rods (30), a tie plate (4), spacers (6), a handle (10), and a joint arrangement (11, 12, 13, 20-25, 31, 32, 33) is provided. The joint arrangement is configured to transfer a vertical lifting force from the handle to the water rods. The joint arrangement comprises a balancing element (20) arranged between the water rods (30) and the handle (10). The joint arrangement comprises a first joint (13) arranged between the balancing element (20) and the handle (10) and a set of second joints (33) arranged between a respective one of said water rods (30) and said balancing element (20). The first joint (13) and the set of second joints (33) are configured to allow a rotational movement of said balancing element (20) in relation to said handle (10) as well as in relation to said water rods (30) in order to balance lifting forces in the water rods. The first joint (13) and each one of said second joints (33) comprise a pair of spherically rounded joint surfaces (11, 23; 25, 32).

Abstract: 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.
