description 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).
