Boiling water nuclear reactor and nuclear reactor fuel assembly for the

Nuclear reactor fuel assembly having a grid-shaped spacer with square grid meshes, wherein mutually parallel rods are arranged, respectively, in a grid mesh, the spacer having flat outer straps extending transversely to the rods and an intermediate strip extending parallel to the rods between two of the respective outer straps, the intermediate strip being inclined relative to the two outer straps, including a rejection rise formed at the outside of the intermediate strip and extending in direction of a diagonal of a grid mesh located at a corner between the two outer straps, the rejection rise being disposed transversely to the two outer straps and being inclined downwardly towards two respective ends of the intermediate strip in longitudinal direction of the rods.

Nuclear reactor fuel assembly

A nuclear reactor-fuel element with cylindrical fuel rods and a fuel element skeleton formed of a head and foot member and cylindrical control rod-guide tubes connecting the members includes a plurality of mesh-forming spacing holder-grids for the fuel rods fastened to the guide tubes, the control rod-guide tubes being received respectively in the mesh formed by the spacing holder-grids, and flow guide means in vicinity of at least one of the spacing holder-grids largely closing, from a flow-technology standpoint, the cross section of the respective mesh surrounding the guide tube received therein.
