<p>A lower end fitting (20) of a nuclear reactor fuel assembly (10) has a stamped plate attached thereto that serves as a debris filter (32) immediately upstream of fuel rods (12) of the fuel assembly. The stamped plate is provided with a plurality of flow holes in a size and pattern that provides filtration of debris that might damage the fuel rods (12) while maintaining adequate coolant flow through the fuel assembly (10). The flow holes may be substantially triangularly-shaped flow holes (36) arranged in square clusters.</p> |
