    • A fuel assembly, particularly, a fuel assembly including short-length fuel rods and fuel spacers, is used for a boiling water reactor, which is capable of sufficiently reducing the pressure loss of at least one of the fuel spacers positioned above the upper ends of the short-length fuel rods, irrespective of the arrangement of the short-length fuel rods, and also ensuring the structural strength of the fuel spacer. The fuel assembly includes fuel rods located in a square lattice array, two water rods arranged in a region in which seven of the fuel rods are arrangeable, two fuel spacers for holding the fuel rods and the water rods with mutual intervals kept immovable. Each of the fuel spacers includes cells which are connected to each other and in which the fuel rods are to be inserted, respectively, and a band for surrounding the outermost peripheries of the cells. The short-length fuel rods include four first short-length fuel rods arranged in the outermost peripheral region of the square lattice array. One of the fuel spacers, positioned upward from the upper ends of the short-length fuel rods, is configured such that the cells located at lattice positions associated with the first short-length fuel rods are removed and instead supporting members, each being adapted to connect two of the cells adjacently located on both sides of each of the lattice positions in the outermost peripheral region to the band, are provided at the lattice positions.

    • With an arrangement that the axial distance from the upper end of a first opening area to the upper end of the second opening area is equal to the axial distance from the upper end of a first coupling member to the upper end of a second coupling member, when a spring member is moved upwardly relative to round cells, the upper end of the second coupling member comes into contact with the upper end of the second opening area, and the spring members receives upwardly acting forces from fuel elements. The spring member is thereby prevented from inclining with respect to flow of a coolant. Simultaneously, the upper end of the first coupling member contacts the upper end of the first opening area, and the spring member is stably held in a condition where it is aligned with the direction of the coolant flow. Also, since the axial distance from the lower end of the first opening area to the lower end of the second opening area is smaller than the axial distance from the lower end of the first coupling member to the lower end of the second coupling member, the lower end of the first coupling member does not come into contact with the lower end of the first opening area when the fuel element is inserted. Thus, the friction force produced during passage of the fuel member along the spring member is small and the fuel element can be inserted more easily.
    • 利用从第一开口区域的上端到第二开口区域的上端的轴向距离等于从第一联接构件的上端到第二联接构件的上端的轴向距离的布置, 当弹簧构件相对于圆形电池向上移动时,第二联接构件的上端与第二开口区域的上端接触,并且弹簧构件从燃料元件接收向上作用的力。 由此防止弹簧构件相对于冷却剂的流动而倾斜。 同时,第一联接构件的上端接触第一开口区域的上端,并且弹簧构件稳定地保持在与冷却剂流动的方向对准的状态。 此外,由于从第一开口区域的下端到第二开口区域的下端的轴向距离小于从第一联接构件的下端到第二联接构件的下端的轴向距离,所以 当燃料元件插入时,第一联接构件的下端不与第一开口区域的下端接触。 因此,燃料构件沿着弹簧构件的通过期间产生的摩擦力小,燃料元件能够更容易地插入。
