"Based on a decree by the Leader of the Islamic Revolution (Ayatollah Seyed Ali Khamenei) and the emphasis put on this issue by the head of the Atomic Energy Organization of Iran, the country is ready to increase its uranium enrichment capacity to 190,000 SWUs," AEOI's Spokesman Behrouz Kamalvandi said on Sunday.
This was because Khamenei's reference to SWUs, a technical measure of the efficiency of enrichment, departed from the usual public discourse about centrifuges, the devices that enrich uranium.
Boroujerdi repeated the 190,000 SWU formulation on July 10, and Iran's negotiators apparently refused to move much on their demands for centrifuge capacity, one of the issues that apparently brought the negotiations to a halt.
(53) The New Mexico facility is expected to produce 3,000 metric tons SWUs annually when it reaches full operational capacity in 2013--meeting approximately 25% of the current U.S.
For the lower SWU estimate, see Mark Hibbs, "CIA Assessment on DPRK Presumes Massive Outside Help on Centrifuges," Nucleonics Week, 25 November 2002, p.
(Table 3), with worldwide annual capacity of 60,850 metric tons SWU. In
Salehi added that the facility can make rotors for around 60 centrifuges of the IR-6 design on a daily basis, noting that one such centrifuge can provide an enrichment capacity of 10 SWUs.
But in August 2014, the head of the Atomic Energy Organization of Iran, Ali Akbar Salehi, stated that IR-1s had "a nominal output of over 3 SWUs, but in practice they yield less than 2 SWUs." He presumably meant SWUs UF6/year, so his figures translate to 1.3 SWUs uranium/year.
Commercial enrichment services are offered by a number of international sources (Table 4), with worldwide annual capacity of 47,855 metric tons SWU. In 2006, U.S.
Ali-Akbar Salehi, the head of the Atomic Energy Organization of Iran, later said different centrifuges have different SWU outputs.
Zonnour said that at present Iran enjoys the capability to produce and assemble 62 centrifuge machines every day, stressing the country's ability to enhance uranium enrichment output to 190,000 SWUs (Separative Working Units) within two years.
