India is the only developing nation to have indigenously developed, demonstrated and deployed nuclear reactors for electricity generation. India has nuclear ores from which a total of about 78,000 tonnes of uranium metal and about 518,000 tonnes of thorium metal can be extracted. If the entire uranium resources are first used in natural uranium–fueled pressurized heavy water reactors (PHWRs), it is estimated that about 420 GWe-yrs of electricity can be produced. Even at an installed nuclear power capacity of 500–600 GWe, the country's nuclear resources will be able to sustain its electricity generation needs far beyond the extinction of its coal deposits.
The first nuclear power reactors built in India were two BWRs at Tarapur, constructed by GE as turnkey projects through Indo-US cooperation. Asia's first nuclear reactor is the Apsara Research Reactor situated in Mumbai.
