IAEA increasingly concerned over uninspected Isfahan enrichment plant

The IAEA said in a new report that it is increasingly concerned about Iran's planned Isfahan Fuel Enrichment Plant, which it has never been allowed to inspect and whose exact location and contents it does not know.

Why it matters: The agency still cannot verify Iran's enriched uranium stockpile, estimated before the June 2025 strikes at about 441 kilograms enriched to 60 percent, which leaves the central question of the nuclear standoff officially unanswered.

The International Atomic Energy Agency said it is increasingly concerned about the Isfahan Fuel Enrichment Plant, a planned uranium enrichment facility in Isfahan that Iran announced on June 12, 2025, a day before Israel began striking its nuclear sites, and that inspectors have never been allowed to visit. In its latest report, seen by news agencies, the agency said it does not know the plant’s exact location or whether it contains nuclear material, and called its lack of information about Iran’s nuclear material and access to facilities a matter of serious proliferation concern that needs to be rectified with the utmost urgency.

Iran initially agreed to let inspectors visit the plant, but the inspection was cancelled after the Israeli attacks began, and since the start of the latest war Tehran has restricted inspector access across its nuclear sites, leaving the agency unable to verify a stockpile it estimated before the June 2025 strikes at about 441 kilograms of uranium enriched to 60 percent, close to weapons grade. Iran says its nuclear programme is for peaceful civilian purposes only and denies seeking weapons.
