Anyway the confirmed quantity of 49,000 tons is sufficient for supporting a nuclear power plant of 8,000 MW capacity for 40 years. Production will start in six months. Uranium deposits in the area appears to be spread over 35 km. The ore is of low grade and will not be enough to cover the expected Indian demand, as India is planning to set up some 30 reactors over as many years and get a quarter of its electricity from nuclear energy by 2050. Over the past three years India has concluded supply deals with France, Kazakhstan and Russia after securing a special exemption in 2008 from the 46-member Nuclear Suppliers Group that governs global nuclear trade to conduct civil nuclear commerce. Until then India had been been subject to an embargo after it tested a nuclear device in 1974.
