Disposal of Nuke Waste is very expensive and must be done under the highest saftly levels and all of that junk. But the cost(I would like to think) would be off set by that we would reduce the number of overall power plants which cuts tons of things such as jobs, overhead and other things which can be shifted to waste disposal.

Even if it costs more after that, I say it is worth it for a cleaner and less poluted earth.
