India has entered into long-term agreements with foreign suppliers to obtain uranium to ensure uninterrupted power supply for its nuclear power plants. Russia and Kazhakhstan are the main suppliers. Besides, talks are going on to obtain uranium from Australia as well. Minister of State in PMO, Dr. Jitendra Singh gave this information in the Lok Sabha today. He said shortage of fuel has been affecting output at the atomic power plants. Currently, the country has 20 nuclear power reactors with an installed generating capacity of 4780 mega watt. The supply of uranium from indigenous sources is improving progressively. The nuclear power plants at Kaiga, Karnataka, Narora, Uttar Pradesh, Kalpakkam, Tamil Nadu and Tarapur in Maharashtra are using uranium obtained from native sources, he added.
