<p>Fuel assembly for a light-water nuclear reactor comprising a plurality of vertical fuel rods (10) which are arranged, in spaced relationship in the lateral direction between a bottom tie plate (11) and a top tie plate (12). The bottom tie plate and the top tie plate are provided with through-holes (35) for inlet and outlet of coolant for the fuel rods. Below the bottom tie plate, in the flow path of the water, a debris catcher (36) is arranged. The debris catcher comprises helical springs (40) which are arranged in a frame comprising at least two ends (37,38) in the form of substantially parallel plates, the flat sides of which are interconnected via pins (39). The pins are arranged in spaced relationship in at least two rows between the ends in such a way that the springs, in spaced relationship or adjacent to each other, can be fixed between the rows of pins in one or more layers.</p> |
