Representatives of the Non-Aligned Movement, the G-77 and the Arab Union, as well as the ambassadors of Syria and Venezuela, will pay a two-day visit to a uranium enrichment plant in Natanz and a heavy water research reactor in Arak on Jan. 15, Iranian representative to IAEA Ali Askar Soltaniyeh was quoted as saying by the ISNA.
He added that the Iranian side is waiting for a response from the other guests.
Earlier, Soltaniyeh sent a letter of invitation to visit Iran's nuclear facilities to the "Six" international mediators to resolve the controversy surrounding the country's nuclear program.
The document said the optimum date for the visit is Jan. 15- 16 before the upcoming negotiations of the Six and Iran in Istanbul. The visit comes ahead of a meeting between Iran and the five permanent members of the U.N. Security Council plus Germany in Istanbul on Jan. 21-22.
"This visit is part of the transparency of Iran's nuclear policy," he said. "I recall that in 2006 we organized a similar visit to the UCF plant in Isfahan for the ambassadors accredited to Vienna."
During the visit, Soltaniyeh said, they are expected to hold a meeting with the senior officials of the Iranian Islamic Republic.
The facilities in Natanz and Arak are part of the complex of Iran's nuclear activities. There are two uranium-enrichment plants - FEP and PFEP in Natanz. Major work on uranium enrichment in Iran is carried out at the FEP separation plant. Based on IAEA Director General Yukio Amano's report, this plant consists of two shops - "A" and "B." Eight complexes consisting of 18 centrifuge cascades will be installed in the "A" workshop. Detailed documentation on "B" has not yet been provided.
