。 A first group of parallel lattice plates, a second group of parallel lattice plates that intersect the first group of lattice plates at right angles, and a first and second group of intersecting lattice plates. In the supporting grid of the nuclear fuel assembly, the supporting grid of the nuclear fuel assembly is composed of a peripheral grid plate surrounding the first group and a peripheral grid plate surrounding the first group, and each intersection of the first group and the second group of grid plates is provided with welding protrusions at both ends. A cutout having a protrusion is formed in the axial center of each grid plate of the first group, and a notch with a protrusion is formed at the intersection of each grid plate of the second group. A support grid for a nuclear fuel assembly, characterized in that a notch is provided with a protrusion formed to engage with the protrusion in the notch of the first group of grid plates when crossed.
