Uranium fever: Where is Iran’s stockpile and who could get it?

Washington and Tehran remain deadlocked over Iran’s nuclear program and its stockpile of highly enriched uranium. Iran has insisted that continuing its nuclear program is its sovereign right, while the US maintains that the program must be abandoned for good and the uranium surrendered.

RT looks into the status of Iran’s uranium stockpile, as well as the positions of Tehran and Washington on the issue as the temporary ceasefire nears its end.

How much uranium does Iran have?

Iran has a sizable stockpile of fissile materials, including uranium enriched up to 60%. While the material is not yet weapons-grade, it could potentially be enriched to that level in a matter of days, depending on the equipment used. Tehran has long maintained its nuclear program serves purely civilian goals and rejected assertions it had been seeking to build nuclear weapons.  

According to the latest comprehensive assessment from the International Atomic Energy Agency (IAEA), published in May 2025, Tehran possessed more than 400 kg of uranium enriched up to 60%, as well as nearly 300 kg enriched up to 20%. Apart from that, the country was believed to hold some 5.5 tons of uranium enriched up to 5%, as well as some 2.2 tons up to 2%.  

Where exactly is the Iranian stockpile?

The whereabouts and status of Iran’s enriched uranium stockpile are debated, and no solid independent assessment of them is available. The IAEA said it had lost “continuity of knowledge” about the stash after Tehran turned off on-site cameras used to monitor its nuclear program in June 2022 in retaliation for what it called a “political” resolution adopted by the organization. In its May 2025 assessment, the organization admitted the knowledge gap was no longer bridgeable.
