Abstract
Abstract A flow deflector for cooling fluid flowing longitudinally in channels between spaced parallel nuclear fuel reactor elements positioned laterally by intersecting grid elements. The deflector comprises a plurality of cones positioned at the intersection of said grid elements with their apexes pointed upstream to deflect the flow laterally toward and across the fuel elements and arranged in spaced staggered relation at different elevations on the grid to reduce flow resistance.
