VIENNA, Feb 27:  Iran has denied the International Atomic Energy Agency access to nuclear facilities affected by the 12-day conflict in June, a confidential report seen Friday by The Associated Press revealed.

The report stresses that the IAEA “cannot verify whether Iran has suspended all enrichment-related activities” or determine the current size of its uranium stockpile at the impacted sites. Without access to the country’s four declared enrichment facilities, the agency cannot confirm the “size, composition, or whereabouts” of Iran’s enriched uranium.

The IAEA warned that the “loss of continuity of knowledge over all previously declared nuclear material at affected facilities” must be addressed urgently.

Iran has long insisted its nuclear program is peaceful, but the IAEA and Western nations maintain that Tehran operated an organized nuclear weapons program until 2003.

Uranium Stockpile Near Weapons-Grade Levels

According to the report, Iran currently holds 440.9 kilograms (972 pounds) of uranium enriched up to 60%, just a short step below weapons-grade levels of 90%. IAEA Director General Rafael Grossi has warned this stockpile could theoretically produce up to 10 nuclear weapons if Iran chose to weaponize its program, though he clarified that the country does not currently possess such weapons.

Highly enriched material is normally verified monthly under IAEA guidelines.

Satellite imagery analysis revealed “regular vehicular activity” around the tunnel complex at Isfahan nuclear facility, a site primarily used to produce uranium gas for centrifuges. The facility was struck by Israel and the United States during the June conflict.

The IAEA also noted activity at Iran’s enrichment sites at Natanz nuclear facility and Fordow nuclear facility, but without on-site inspections, the agency could not confirm the nature or purpose of the operations.

Iran allowed inspectors access to other, unaffected nuclear sites at least once since the June attacks, except for the Karun Nuclear Power Plant, which is still under construction and contains no nuclear material.

IAEA Involvement in U.S.-Iran Talks

The report confirmed that Grossi attended negotiations between the United States and Iran on February 17 and 26 in Geneva, offering guidance on verifying Iran’s nuclear activities. Discussions are ongoing, though last week’s talks ended without a deal.

The Trump administration has conducted multiple nuclear negotiation rounds this year under Oman’s mediation. Oman’s Foreign Minister Badr Al-Busaidi said technical discussions will continue next week in Vienna.

The United States seeks a deal to curb Iran’s nuclear program and prevent the development of nuclear weapons. Iran maintains it is not pursuing weapons and has resisted calls to halt uranium enrichment or surrender its stockpile of highly enriched uranium.

Before the June war, Iran’s uranium enrichment reached 60% purity, just below weapons-grade, highlighting the ongoing international concern over the program.
