ABSTRACT:
A fuel assembly lower tie-plate with better performance in capturing linearly elongated foreign substances. The lower tie-plate has a screening plate positioned below the network section in the lower tie-plate cavity. The screening plate is arranged substantially horizontally so that the lower tie-plate cavity is divided into upper and lower parts by the screening plate. Tubular filters are attached to the screening plate so that the tubular filters have openings below and above the screening plate. Top ends of the tubular filters are closed, and the openings above the screening plate are formed in side walls of the tubular filters. The lower tie-plate may be assembled by combining the screening plate, the network section and the nozzle section together, after the tubular filters have been attached to the screening plate.
