Abstract

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.
