Abstract
The invention refers to a spacer for holding a number of elongated fuel rods intended to be located in a nuclear plant, and a fuel unit with such spacers. The spacer encloses a number of cells for receiving a respective fuel rod extending in parallel to a longitudinal axis of the respective cell. Each cell is formed by a sleeve-like member having an upper edge and a lower edge. The sleeve-like member includes a number of abutment surfaces projecting inwardly towards and extending substantially in parallel with the longitudinal axis for abutment to the fuel rod the cell. The lower edge and the upper edge have, seen transversely to the longitudinal axis, a wave-like shape with wave peaks, aligned with a respective one of said abutment surfaces, and wave valleys located between two adjacent ones of said abutment surfaces.
