Gholamreza Aghazadeh, the head of Iran's Atomic Energy Organization, told the official IRNA news agency that the country intends to continue building centrifuges to enrich uranium for future nuclear power plants.
In its latest report on Iran's nuclear program, the International Atomic Energy Agency, the UN nuclear watchdog, said that 6,000 uranium enrichment centrifuges had already been installed at Iran's Natanz nuclear center, and that 3,800 of them were in operation.
Iran has obtained an estimated two tons of enriched uranium since its uranium enrichment activities restarted at Natanz two years ago.
Iran is under three sets of relatively mild UN Security Council sanctions over its nuclear program, which it insists has purely civilian goals. Western powers led by the United States, along with Israel, accuse Tehran of attempting to develop nuclear weapons, something Iran has consistently denied.
