Why do we want to get rid of it, anyway? Nuclear "waste' is a resource, not a liability. Uranium and plutonium, the elements that give the stuff its long life, can be separated and fed back to reactors to create more energy. Japan and France already recycle their waste in this way; the only reason we don't is that the process is still expensive. Since we have plenty of raw uranium and arid land, it makes more sense for us to store waste ion the desert for the next hundred ears or so until recycling gets cheap.
This is a far better ultimate solution than those daffy schemes for shooting waste into the Sun.
Or... we could pile the waste up in the desert underneath a huge inverted funnel with turbines in the 'spout' and generate electricity from the rising hot air.
(have to admit I stole the idea from the solar project in Oz)
