An indigenous design for a Thorium nuclear reactor, which can produce 600 MWs of power for two years without being replenished, was unveiled on Thursday by two Indian scientists at an international conference on emerging nuclear energy systems in Brussels (ICENES 2005).
Designed by scientists (V Jagannathan and Usha Pal) of the Bhabha Atomic Research Centre (BARC), the thorium breeder reactor (ATBR) has been claimed to be far more economical and safer than any other in the world. More importantly, the reactor doesn’t need expensive and scarce Uranium²³⁵. Although it would require Plutonium initially, the reactor will eventually run entirely on Thorium and Uranium-233, the scientists said.

Nuclear analysts say that it may be possible for India to obtain Plutonium from friendly countries wanting to dismantle their weapons or dispose of their stockpiled plutonium:):).
