However, long term interment isn't what's planned anyway... the fuel rods can be reprocessed into new fuel, and they aren't much of a storage concern anyway... they can actually be stuck on a truck and hauled away in their casks down the highway.
We need somewhere to store the fuel assemblies that's safe and secure (or better than putting them in casks in the open) but we're not looking for a dump site. More like a warehouse facility, where they can sit until reprocessed or dismantled.
