ABSTRACT:
To ensure proper registry of nuclear fuel pellets with fuel pins during loading of pellet stacks into the pins, the pellets are guided through a passageway 28 formed with ribs 42 and pins are located in coaxial passageway 30 also formed with ribs 44. The ribs 42, 44 make substantially line contact with the pellets and pins to reduce the risk of jamming, particularly in the case of the pellets, and the inter-rib spaces serve to collect any dust generated from the friable pellets during feed thereof. Instead of ribs, the passageways may be of polygonal cross-section such that the flat faces of the polygon make substantially line contact with the pellets and pins.
