If we develop thorium reprocessing technology what will happen to nuclear plants, running on Uranium processing technology???After all thorium processing units are totally different from the former. You have to close them after spending billion dollar in buikding it!!. In that hypothetical situation there is no point in running nuclear power plants with Uranium reprocessing technology along with thorium processing plants as we ourselve has plenty of Thorium reserve and will not have to import Uranium from US and Australia!!! This will never happen and we will continue to import Uranium as this will suite political and financial interests of so called politicians
