A nuclear fuel assembly storage rack having a swivel base consisting of a plurality of plates with a hard ball centered and captured between the plates. The bottom base plate is fixed to the bottom of the storage rack and the top base plate has pins for locating the bottom nozzle of the fuel assembly. Since the top of the fuel assembly is clamped in the storage rack, the swivel base allows the fuel assembly to seek a position that minimizes torsional and bending stresses in the fuel assembly.
