Abstract
An unirradiated nuclear fuel assembly transport canister that includes a clamshell type fuel assembly inner liner that has interior dimensions that closely conform to the outer envelope of the fuel assembly to be transported and exterior dimensions that conform to a generic overpack tubular container. The liner is inserted into the overpack tubular container which is in turn supported by a shock absorbing suspension system within a birdcage frame.
Claims24
A shipping container for a first nuclear fuel assembly comprising:
- an elongated, tubular container having an axial dimension at least as long as the fuel assembly and an internal cross-section larger than the first nuclear fuel assembly;
- an elongated, inner, tubular liner having an axial dimension at least as long as the fuel assembly and an external circumference that is designed to be closely received within the interior of the tubular container, the liner having an internal cross-section that substantially, closely matches an external cross-section of the first nuclear fuel assembly;
- an elongated, external frame having an axial dimension at least as long as the tubular container, sized to receive the tubular container within the external frame in spaced relationship from the frame;
- and
- shock absorbing means for attaching the tubular container to the frame so that the tubular container is suspended substantially within the frame in a manner so the shock absorbing means isolates the tubular container from a substantial amount of any impact energy experienced by the frame should the external frame be impacted.
