History

Historical Context

After the P5+1 and Iran signed the Joint Comprehensive Plan of Action on 14 July 2015, the deal capped Iran’s operating centrifuges at 5,060 and cut its 3.67 %-enriched uranium stockpile to 300 kg. Today a preliminary framework asks Iran to reveal 440 kg of 60 % uranium and submit to IAEA inspections led by Director General Rafael Grossi, aiming to restore the 2015 sanctions relief.
