Nuclear reactor fuel assembly and method of forming same
A nuclear fuel assembly is described comprising: a top nozzle assembly; a bottom nozzle assemble spaced from the top nozzle assembly guild thimble tubes extending between the top and bottom nozzle assemblies; spacer grid assemblies axially spaced along and attached to the guild thimble tubes; fuel rods held in a spaced lateral array between the top and bottom nozzle assemblies by the spacer grid assemblies. Each of the fuel rods comprises a fuel zone and a fission gas plenum zone wherein a first group of the fuel rods are disposed in the fuel assembly with the fission gas plenum zone adjacent the top nozzle assembly and a second group of the fuel rods are disposed in the fuel assembly with the fission gas plenums adjacent the bottom nozzle assembly. The fuel zone of the first group of fuel rods is axially shifted with respect to the fuel zone of the second group of fuel rods.
