U.N. nuclear chief Rafael Grossi has revealed that Iran’s new uranium enrichment facility is located in Isfahan.
Iran had announced plans to soon activate the plant as retaliation for a diplomatic rebuke from the International Atomic Energy Agency.
The announcement came just before Israeli forces launched strikes on Iranian nuclear sites last Friday, Grossi said Thursday.
The planned facility would have been Iran’s fourth operational enrichment plant, but Israeli attacks disrupted those plans.
Israeli strikes destroyed one existing plant and disabled another by severing its power supply, according to the IAEA.
Grossi said inspections of the new Isfahan facility were scheduled but have been postponed due to the Israeli military action.
He described the nuclear complex in Isfahan as “huge” but did not specify the exact location of the new plant.
The IAEA reported that Israeli strikes damaged four buildings at the complex, including the key Uranium Conversion Facility.
That facility transforms raw uranium, or “yellowcake,” into feedstock for centrifuges used in uranium enrichment.
Grossi told the BBC that Isfahan’s underground spaces—where much of Iran’s highly enriched uranium is stored—appear undamaged.
However, the IAEA has been unable to verify the situation on the ground, as inspections have not resumed since the attacks.
The Israeli strikes followed an IAEA resolution declaring Iran in breach of its nuclear non-proliferation obligations.
Diplomatic tensions remain high as the international community watches Iran’s next moves in its contested nuclear programme.
