Because once you spend million dollar in developing the nuclear power plants with Uranium reprocessing technology( not thorium !!) you will have to buy it from NSG countries. You have no option left out. It would have been much prudent to develop thorium processing plants with indigenous technology as we have huge reserve of Thorium!! This was the arguement raised by scientists from IISC Bangalore and from Bhaba Atomic research Institute!!! They are not fool after all
