TEHRAN (AFP/Reuters) - Iran said on Saturday it will put its newly disclosed uranium enrichment plant under the supervision of the UN nuclear watchdog. Iranian officials voiced defiance, with one saying he hoped the plant, under construction southwest of Tehran, would soon be ready and blind Irans enemies and another expressing shock that the world was not grateful it had revealed its existence. The new nuclear fuel facility will soon become operational, an aide to Supreme Leader Ayatollah Ali Khamenei was quoted as saying on Saturday. This site will be under the supervision of the IAEA (International Atomic Energy Agency) and will have a maximum of five per cent (uranium) enrichment capacity, Ali Akbar Salehi said on state television. The plant, which is not an industrial scale unit, will be operational in two years time, he said. Dismissing allegations that the plant has a military purpose, Salehi said the facility is being constructed as a precautionary measure in case of an unwanted incident against our nuclear programme. He said Irans nuclear installations are facing threats every day and so Tehran had to take measures to disperse the locations of its installations. Earlier on Saturday Salehi said Tehran would allow IAEA inspectors to inspect the plant, which is sited 100km south of Tehran on the road to Qom - the first official disclosure of its location, and would fixt date for this purpose. This new plant, God willing, will soon become operational and will make the enemies blind, Mohammad Mohammadi-Golpayegani, who heads Khameneis office, said, according to the semi-official Fars News Agency. Mohammadi-Golpayegani, a cleric, said the construction of the plant was a sign of Iran being at the summit of power, Fars reported. He was speaking at a ceremony marking the start of the 1980-88 Iran-Iraq war. The announcement of the new facility came just days before an October 1 meeting in Geneva between Iran and six world powers to discuss Tehrans disputed atomic programme. Salehi said the plant is a guarantee Tehrans nuclear work will continue. Considering the threats (to existing nuclear sites), our organisation decided to do what is necessary to preserve and continue our nuclear activities, he said. So we decided to build new installations which will guarantee the continuation of our nuclear activities which will never stop at any cost.
