Iran's plans to inject UF6 into IR8 machine had been earlier announced by AEOI Spokesman Behrouz Kamalvandi.
Iran's total enriched uranium stockpile did not exceed 300 kg of UF6 enriched up to 3.
Solid UF6 is a white, dense, crystalline material that resembles rock salt [20].
This clause can be used to bypass the cap on 300 kg limit on UF6 stockpile.
5 tonnes of low-enriched UF6 to make an initial bomb, then another tonne for each subsequent device.
Iran has become self-sufficient in the entire fuel cycle, starting from (uranium) exploration, mining and then turning it into yellowcake and converting it to UF6 and then turning it into fuel plates or pellets," he said.
For this enrichment process to occur, the uranium must be in gaseous form, and this is carried out by conversion into uranium hexafluoride (UF6), which is a gas at relatively modest temperature (solid UF6 sublimes at 56[?
22 kilogrammes or UF6 enriched up to 20 per cent has been produced" at its pilot fuel enrichment plant in Natanz, the report said.
Earlier production of UF6 at the Port Hope conversion facility has been suspended since December 2008 as the company could not obtain a supply of hydrofluoric acid (HF) on acceptable terms.
N body's experts claimed more than 7,000 uranium-enriching centrifuges have been installed at the Natanz facility with "4,920 centrifuges" being fed with UF6.
There is a factory to produce UF6 in Iran," Mohammad Qannadi told IRNA.
Since the director general's previous report, Iran has continued to feed UF6 [uranium hexafluoride] into the 3,000-machine IR-1 unit (Unit A24), and five cascades of Unit A26, at the Fuel Enrichment Plant (FEP).
