The International Atomic Energy Agency (IAEA) said its inspectors have not found that Iran is attempting to process low-enriched uranium into weapons-grade uranium, the Austrian Press Agency (APA) reported on Friday. The report quoted an anonymous IAEA expert as saying, "so far, Iran has carried out good cooperation with us in relevant verifications." The uranium substances produced in Natanz (plant) have all been carefully registered, some of which are under the supervision of IAEA's remote cameras, the expert said. "If the Iranians intend to transport these uranium substances to a secret location for further processing, agency's inspectors will find out." In a report submitted on Thursday to the United Nations Security Council, Mohamed ElBaradei, director general of the IAEA, said Iran was still refusing to fulfill the UN's requirement of stopping its uranium enrichment activity. The report said Iran had so far produced around 1,000 kg of low-enriched uranium, an amount according to experts, was sufficient to produce weapons-degree enriched uranium with 95 percent purity required for one nuclear bomb. The United States and its allies have accused Iran of trying to develop nuclear weapons under the guise of a civilian nuclear program, which Tehran denies. Iran insists that its nuclear plan is only for peaceful purposes, and continues its uranium enrichment activity despite pressures from Western countries and relevant UN resolutions and sanctions.
