Iran no longer allowed verification of its nuclear program since 2025 attacks / Where it hid its uranium enriched to 60% purity

The International Atomic Energy Agency (IAEA) warned on Friday that Iran is not providing it with access or information on the most sensitive aspects of its nuclear program since the attacks by Israel and the United States on its facilities in June 2025, EFE and Agerpres agencies report.

Although the IAEA recognizes that these attacks have created “an unprecedented situation”, it considers it “indispensable and urgent” that Iran once again submits to international nuclear controls.

Without this access, the IAEA “cannot verify the condition of the attacked nuclear facilities, nor their associated nuclear material,” including large quantities of enriched uranium, a material that can be used to make atomic bombs.

The director general of the IAEA, Rafael Grossi, sent these warnings in a report issued before the technical negotiations between the US and Iran scheduled for next week in Vienna, after those held on Thursday in Geneva, a report consulted by EFE.

440 kilograms of highly enriched uranium, impossible to verify

Among other restrictions mentioned, the Islamic Republic does not grant IAEA inspectors access to all facilities attacked last June.

For this reason, the IAEA does not know where, for example, the stockpiles of enriched uranium are, especially the 440 kilograms with a purity of 60%, very close to that needed to make nuclear bombs.

This lack of access and information about this material means that its verification, according to the usual safety practices (controls), is “very delayed”, criticizes the situation of the IAEA.

“Due to the lack of access to Iran's four declared enrichment facilities, the agency cannot provide any information on the current size, composition or location of Iran's enriched uranium stockpiles,” Grossi said in the report.

Where is the stockpile of 60% enriched uranium kept

Some of the highly enriched uranium, close to weapons-grade, has been stored in an underground area of ​​its nuclear site in Isfahan, Reuters news agency said, citing the confidential IAEA report sent to member states on Friday.

Reuters notes that this is the first time the IAEA has reported where uranium enriched to 60 percent purity has been stored.

The entrance to the tunnel complex was hit in US and Israeli military raids last June, but the facility appears to have remained largely intact, diplomats say.

The IAEA Board of Governors, the agency's executive body, will hold a meeting next week that will again focus on Iran's nuclear program.

Outside that meeting, Iranian and US delegates will meet in Vienna, brokered by Oman, to advance negotiations on a nuclear deal to prevent another US attack on the Islamic Republic.
