Meanwhile, Supreme Leader of Iran's Islamic Revolution Ali Khamenei on Monday ordered authorities to raise uranium enrichment to 190,000 SWU (separative work units).
Jalili said, "Under this deal, we would need some 40 years to reach the 190,000 separative work units the Supreme Leader has underlined that the country needs." He did not explain how he made that calculation.
Iran had also warned last year that it enjoyed the capability to restore its uranium enrichment operations and even develop its capacity to 100,000 SWUs (Separative Work Units) if the nuclear deal with the world powers failed as a result of the US non-compliance with its undertakings.
