发明名称 SPACER GRID FOR A NUCLEAR REACTOR FUEL ASSEMBLY
摘要 The invention concerns a spacer grid (1) comprising along the top edge of each of the cells (3) for receiving a fuel pencil (4), mixing vanes (7, 8) projecting upwards, arranged in the proximity of the angles of the cells and bent, alternately, inwards and outwards of the cell (3), in the proximity of the cell (3) angles. In each of the zones of the top edges of the pencil cell (3) walls next to the angles and not comprising mixing vanes (7, 8) is provided a matching deflecting element consisting of a straight vane (16). On each of the straight vanes (16) arranged in the cell wall plane, the outer edge of a bent mixing vane (7, 8, 9, 10) is urged to press. The matching deflecting elements can also consist of parts of the top angle of the cell (3) walls alternately bent inwards and outwards of the cell, above the cells adjacent to the cell (3).
