description PROBLEM TO BE SOLVED: To provide an fuel assembly for a pressurized water reactor including intermediate flow mixing grids. SOLUTION: The fuel assembly includes a bottom nozzle, a plurality of elongated guide thimbles projecting upwardly from the bottom nozzle, an array of fuel rods, and various supportive structure axially spaced along the guide thimbles, and at least two intermediate flow mixing grids. The flow mixing grids is equipped with different configurations of mixing device formations, disposed within pairs of non-uniformly spaced, adjacent support grids at selected locations.
