Thorium reactors may or may not happen, but one nice part of a LFTR is that it can continuously burn up long lived fissile isotopes into short lived ones. Part of a LFTR's operating requirements are to filter the isotopes and extract or send them back in. Perhaps one day, we can reprocess long lived nuclear waste into shorter lived waste, and this won't be such a big problem.
