VIENNA, July 9 — Rafael Grossi, the Director General of the International Atomic Energy Agency, continues to serve as the lead international official overseeing Iran’s nuclear activities, a position that has placed him at the center of escalating tensions between Tehran and the IAEA’s Board of Governors. According to the record, Grossi has reported to the board that Iran’s stockpile of enriched uranium now exceeds 5,000 kilograms, and that the country is enriching uranium to 60% purity.
Officials confirmed that Grossi has repeatedly called on Iran to cooperate with IAEA inspections and to grant access to undeclared sites, demands that have so far met with limited compliance.
A Career in Nuclear Diplomacy
Grossi, an Argentine diplomat born on January 29, 1961, in Buenos Aires, has held the post of IAEA Director General since December 3, 2019. His career in the Argentine foreign service began in 1985, following a degree in political science from the University of Buenos Aires and a master’s degree in international relations from the University of Geneva.
The record shows that Grossi served as Argentina’s ambassador to the IAEA from 2013 to 2019, and prior to that, as the agency’s Deputy Director General and Head of the Department of Safeguards from 2014 to 2017. This background in both national diplomacy and international safeguards has shaped his approach to the current crisis.
Iran’s Nuclear Escalation
In June 2024, Grossi confirmed that Iran had begun installing advanced IR-6 centrifuges at the Natanz facility. These machines are capable of enriching uranium far more efficiently than the older IR-1 models, and their installation represents a significant technical leap. According to the statement, the IAEA’s monitoring of Iran’s activities has been a central focus of Grossi’s tenure, with his reports to the board detailing the steady growth of Iran’s enriched uranium stockpile and the lack of full transparency from Tehran.
The 5,000-kilogram threshold and the 60% enrichment level are both well beyond the limits set by the 2015 Joint Comprehensive Plan of Action, which the United States withdrew from in 2018.
The Ukraine Nuclear Dimension
Grossi has also overseen the IAEA’s response to the war in Ukraine, including inspections of the Zaporizhzhia nuclear power plant. That facility, Europe’s largest, has been under Russian military control since early in the conflict, and the IAEA has maintained a presence there to monitor safety and security. Officials confirmed that Grossi has personally led efforts to establish a protection zone around the plant, though a formal agreement has not yet been reached.
His work on both the Iran and Ukraine fronts has drawn international attention, and he has been nominated for the Nobel Peace Prize for his efforts to prevent nuclear proliferation.
What to Watch Next
Grossi’s term as Director General runs through 2025, and the coming months will likely see continued pressure on Iran to comply with IAEA demands. The board’s next quarterly report, expected later this year, will provide an updated assessment of Iran’s stockpile and enrichment activities. Officials confirmed that Grossi speaks Spanish, English, French, and Italian, a linguistic range that has facilitated his diplomatic engagements across multiple continents.
The strategic context remains clear: as Iran’s nuclear capabilities expand, the IAEA’s ability to verify and monitor those activities will be a key factor in determining whether the situation can be managed through diplomatic means.
