It provides a fuel rod support grid comprising a plurality of recessed portion pattern formed in the dimple part or parts of contact surfaces of the support grid spring contacting the fuel rod. The fuel rod support grids in wear resistance according to the present invention improved stores the cooling water in the dimples, or by having a pattern formed into a plurality of recesses having a predetermined size on a contact surface of the spring, the fuel operating conditions of number lubrication of the support grid to contact the nuclear fuel rods and and it may serve to re-supply and hydrodynamic phenomena through the sea pressures pocket (hydrodynamic pressure pocket phenomenon) to reduce friction, wear and tear. In addition, it is possible in one direction rather than reducing the irregular nuclear fuel rods, caused by the vibration of the support grid. Furthermore, holding less than it costs to develop new technologies and materials can be applied directly to existing materials, the benefits are very short development period.
