This patent describes an improvement in a fuel element grid integral spring for supporting a plurality of nuclear fuel elements intermediate their ends in spaced relation for fluid flow therebetween. The grid including a polygonal perimeter strip and a first and second plurality if half-slotted interlocking divider strip members arranged in a transverse intersecting egg-crate fashion to define a plurality of fuel element cells. The improvement in which the fuel element support grid has each integral element support spring and definding cutout located in the slotted half of the divider members thereby making the material that is parallel and makes up the half-slots and integral spring cutouts.
