TEHRAN (Dispatches) -- Head of the Atomic Energy Organization of Iran (AEOI) Ali Akbar Salehi said Sunday 1,044 centrifuges are currently operating at Fordow uranium enrichment site. The operation shows Iran has taken in full the fourth step it had promised to reduce its commitments under a landmark nuclear deal officially known as the JCPOA, he added. "The fourth step to reduce JCPOA commitments by Iran has been taken in full as a result of which, 1,044 centrifuges are now doing the enrichment work at Fordow site,” Salehi said.  Under the nuclear deal, Iran had undertaken that these 1,044 centrifuge machines would not enrich uranium, but in line with the policies to reduce JCPOA commitments, the country is now enriching uranium to the amount it requires and we will stockpile the enriched materials, Salehi noted.
