An International Atomic Energy Agency (IAEA) report says it does not know the exact location of Iran’s declared Isfahan enrichment plant or whether it contains nuclear material after a bombing campaign disrupted a planned inspection. Reuters reported Friday that it had seen the report, which was sent to IAEA member states.
Iran declared the Isfahan Fuel Enrichment Plant (IFEP) to the IAEA on June 12, 2025. The agency had planned to inspect IFEP on June 13, the day the 12-day bombing campaign began. The strikes destroyed or badly damaged Iran’s other uranium enrichment plants.
Diplomats believe IFEP is in a tunnel network at Isfahan. A senior diplomat said the plant’s location and status remained unknown. IAEA Director General Rafael Grossi said in March that the agency believed a significant amount of Iran’s most highly enriched uranium was in the Isfahan tunnel complex.
The report says Iran has not allowed inspectors to visit IFEP or review its design plans. It urged Tehran to restore inspection access at sites damaged in the campaign and provide updated information on its enrichment facilities and uranium holdings. The agency said the verification gap warrants urgent attention, calling it a “serious proliferation concern.”
The report’s focus on IFEP adds a specific facility to the access and stockpile verification issues described in EconoTimes’ earlier coverage of the IAEA’s Iran inspection request.
