摘要： A mixer grid for a nuclear reactor fuel assembly has a plurality of strips arranged in interlocking rows and columns defining a plurality of cells. A stopper is fixed to each corner of each cell for both directing coolant flow, providing coolant mixing and providing a smooth contact surface for the fuel rod. The stopper is either cone-shaped or cylindrical for directing and channeling coolant flow. The stopper also has a smooth, flat chamfered surface for contacting the fuel rod and minimizing damage upon the shifting of the fuel rod. The grid is attached to the nuclear reactor fuel assembly by using guide cells comprising a plurality of support arches for welding to the nuclear reactor fuel assembly.

摘要： A spacer grid for a nuclear fuel assembly. A plurality of metal strips are interleaved on edge to define a plurality of individual cells. Each cell is sized to receive a single nuclear fuel rod. A series of projections, grid mixing vanes, extend from one edge of each metal strip and are alternately bent to extend on opposite sides of the metal strip. The alternating projections provide four grid mixing vanes that extend into each individual cell.
