A recent report from the International Atomic Energy Agency (IAEA) has highlighted significant gaps in the inspection and monitoring of Iran's nuclear facilities, with a particular focus on the unclear status of the Isfahan facility. The agency has been unable to conduct on-site verification of its activities for six months.
According to the report obtained by 'Al Arabiya English,' the IAEA confirmed that it has not conducted any field verifications at Iranian nuclear facilities since February, which has limited its ability to assess developments in Iran's nuclear program.
The report also noted that the IAEA has not been able to monitor the activities of centrifuges in Iran, stating that it remains unaware of the precise situation at the Isfahan enrichment facility.
This comes after IAEA Director General Rafael Grossi stated in an undisclosed report that Iran continues to refuse cooperation with agency inspectors, leaving them unaware of the controversial uranium stockpiles amid ongoing tensions with the United States.
The report noted that Tehran has not provided the Vienna-based agency with any information about approximately 440 kilograms of uranium, an amount that experts say could be sufficient to produce several nuclear weapons if further enriched to a higher degree.
Before the U.S.-Israeli strikes in June 2025, the IAEA estimated that Iran possessed about 440 kilograms of uranium enriched to 60%, nearing the 90% level required to produce a nuclear weapon and far exceeding the 3.67% limit set by the 2015 agreement between Iran and major powers.
However, the fate of this stockpile remains uncertain since June 2025.
In June, Grossi mentioned that the "prevailing impression" was that the stockpile remains at its previous location near the Isfahan nuclear facility.
The Isfahan facility is a key center of Iran's nuclear program, housing a sprawling complex for uranium processing, conversion, and nuclear fuel manufacturing. It includes a uranium conversion facility producing materials used in the nuclear fuel cycle, and equipment related to centrifuge components and uranium processing.
The site gained additional significance after Iran announced a new uranium enrichment facility at an Isfahan tunnel complex in 2025. Parts of the complex sustained damage during strikes targeting Iran's nuclear installations last year.
