A delegation of Non-Aligned Movement (NAM) and Group of 77 representatives arrived at the uranium conversion facility in the central city of Isfahan together with foreign and Iranian journalists for a guided tour.

The delegation includes the International Atomic Energy Agency (IAEA)'s ambassadors from Cuba, Malaysia and Egypt -- representing the NAM -- Sudan and Bolivia from the Group of 77 as well as the Algerian envoy.

Raw mined uranium, or "yellowcake", is transferred to the uranium conversion facility at the foot of the mountains on the edge of the central city of Isfahan, the ancient capital of Persia.

The mined uranium is transformed into uranium tetrafluoride (UF4) and then into uranium hexafluoride (UF6), a feed gas for the actual process of enrichment.
