The IAEA estimated that Iran’s enriched uranium stockpile stood at 1021kg through 19 February 2020, with enrichment rates topping out at 4.5 per cent. Separately from its quarterly report, the IAEA issued a report in which the director general indicated that “as a result of its ongoing investigations, the Agency identified a number of questions related to possible undeclared nuclear material and nuclear-related activities at three locations in Iran that had not been declared by Iran”. It further noted that “Iran has not provided access to the Agency to two locations… and not engaged in substantive discussions to clarify Agency questions related to possible undeclared nuclear material and nuclear-related activities”. In an interview, IAEA Director General Rafael Grossi asserted that “Iran must decide to cooperate in a clearer manner with the agency to give the necessary clarifications… The fact that we found traces [of uranium] is very important. That means there is the possibility of nuclear activities and material that are not under international supervision and about which we know not the origin or the intent”. Iran’s IAEA envoy maintained that “the U.S. and the Israeli regime are trying to disrupt the active and constructive cooperation and relations between the IAEA and Iran by pressuring the Agency to step outside its constitutional duties”, adding that “the IAEA’s request for clarification or additional access on the basis of fabricated information provided by spy services, including the Zionist regime [ie, Israel], is not only inconsistent with the Agency’s founding documents and verification regime, but it also makes no obligation for Iran to comply with these demands”.
