ABSTRACT:
A grid structure of slotted straps interfitted at their slots to form cells containing fuel elements or thimbles. The straps are of nonuniform thickness having strips of substantially greater thickness than the regions between the strips. The strips of greater thickness extend parallel to the slots. The straps are joined along these strips of greater thickness. Grids of zirconium alloy resisting crushing are formed by joining intersecting straps by welds in the strips of greater thickness.
