The enrichment procedures will be conducted at the Natanz enrichment site in Iran's Isfahan province, INRA, the Islamic Republic News Agency, reported.
Additionally, Fereydoun Abbasi, head of Iran's Nuclear Energy Organization, said Saturday second and third generation centrifuges have been successfully tested.
Abbasi made the comments at a ceremony in Tehran commemorating the fifth nuclear technology festival. He said first generation centrifuges are producing enriched uranium to a level of less than five percent.
Abbasi also said safety considerations have delayed the commissioning of the Bushehr power plant.
