To hear proponents talk about Thorium reactors, you would think that Thorium is the energy panacea for which we have been searching. This readily found element can be used to create nuclear reactors that are walk-away safe, with waste that has a much shorter half life and should be easier to dispose of. Current, nuclear reactors need multiple redundant systems and can blow up as we’ve seen with Fukishima. Thorium reactors won’t blow up and don’t need the multiple redundant systems. If they are so great why are we still using Uranium reactors?
