ABSTRACT:
A device for aligning nuclear fuel pellets, for insertion into fuel rods, comprises a vibrating table and a conveyor assembly adapted to receive pellets poured from a container and to deposit them in a single layer on the table. The upper surface of the table is formed with a number of parallel, substantially v-shaped grooves in which the pellets become aligned. The conveyor assembly, which comprises a horizontal traveling belt and an inclined planar slide, is slid along above the table to facilitate the distribution of pellets thereon. An inspection station, adjacent the table, comprises a number of rotating, parallel rollers in columnar-flow communication with the table grooves. Aligned pellets from the table are delivered onto the rollers where they slowly rotate, presenting their circumferential surfaces for visual inspection. A displaceable control member, transversely disposed between the table and the inspection station, controls transfer of pellets therebetween. A number of trough members, each adapted to receive a column of aligned pellets, are releasably attachable to the distal end of the inspection station.
