Ardakan Yellowcake Production Plant

The Yellowcake Production Plant at Ardakan, formerly a pilot-scale facility, processes between 50 and 70 tons of uranium ore per year into yellowcake (U308 or uranium ore concentrate). ¹ The plant officially entered service in April 2013. ² Iran did not initially disclose to the international community its intention to turn the Ardakan pilot plant, constructed with Chinese assistance, into a larger facility. ³ The National Council of Resistance of Iran, an organization that opposes the current Iranian regime, disclosed this allegation to the public in July 2003, and Iran confirmed its intention to build a full-scale milling facility at Ardakan in September 2003. ⁴

Because it is widely believed by proliferation analysts that the Ardakan facility provides milling services to the Saghand mine, whose output is approximately 50 tons of uranium ore per year, most estimates from non-Iranian sources suggest Ardakan possesses a 50 ton processing capacity. ⁵ In 2013, Iranian state television stated that Saghand and Ardakan will be able to produce 60 tons of yellowcake per year.⁶ In 2008, Hossein Faghihian, deputy head of the AEOI in charge of nuclear fuel, stated that Ardakan would have a 70 ton processing capacity. ⁷ In order for the latter figure to be accurate, Iran would have to either increase the Saghand mine’s output or process additional ore from mines other than Saghand. Furthermore, as the PIR Center’s Anton Khlopkov and Vasily Lata point out, roughly 150 tons of yellowcake is necessary in order to fabricate fuel for one VVER-1000 reactor. ⁸ Ardakan’s projected output is therefore clearly insufficient to indigenously fuel the Bushehr VVER-1000, but it would provide valuable additional resources should Iran wish to accumulate additional feedstock for its enrichment program. This is especially true if Iran’s efforts to enrich uranium to the 20% U-235 level beginning in February 2010 isolate it from potential foreign suppliers of additional yellowcake. To derive material suitable for enrichment, Iran would only need to run the yellowcake through a uranium conversion facility, such as it possesses at Isfahan (Esfahan). ⁹ Indeed, in January 2019 the Islamic Republic News Agency (IRNA) announced that Iran shipped 30 tons of yellowcake from the Ardakan facility to its uranium conversion facility in Isfahan.¹⁰

Iran announced in April 2013 that it began operations at the Saghand mines and the Ardakan facility. ¹¹
