  • Distributed clumping of part-length rods for a reactor fuel bundle
    Patent number: 8559586
    Abstract: A reactor fuel bundle includes both full-length fuel rods and part-length fuel rods. The part-length rods are clumped in two groups—a first rod group surrounds one or more water passages which are generally centrally disposed in a channel of the fuel bundle, and a second rod group is distributed about an inner perimeter wall of the channel.

  • Axially segregated part-length fuel rods in a reactor fuel bundle
    Publication number: 20050157838
    Abstract: A reactor fuel bundle includes a channel having an inner perimeter wall and a channel longitudinal centerline. Both full-length and part-length fuel rods are positioned within the channel. The part-length rods are separated into two groups. A first group has intermediate-length rods located immediately adjacent to the inner perimeter wall. A second group has short-length rods located approximate the channel longitudinal centerline.
