Abstract
A lower tie plate includes a lower, generally cylindrically shaped nozzle for communicating coolant through a transition section of the tie plate to a grid at the upper end of the lower tie plate. The transition section is in the geometric form of a truncated, inverted pyramid, with flat side walls intersecting the cylindrical nozzle and the undersurface of the square grid. In this manner, minimum pressure loss is achieved by the flow from the nozzle to the grid. A shaped body diverter, i.e., an inverted pyramid, may depend from the grid to divert the flow laterally with minimum pressure loss into regions where the flow is most needed in the fuel bundle, i.e., in and about the fuel rods rather than the water rods. The inverted solid may have coolant flow passages through the solid to direct the flow into registering openings in the grid.
