UN Report: Iran's Enriched Uranium Stockpile Grows Amid Inspection Stalemate

A confidential report from the International Atomic Energy Agency (IAEA) indicates that as of June 13, 2025, Iran's stockpile of uranium enriched up to 60% reached 440.9 kilograms, marking an increase of 32.3 kilograms since the agency's previous assessment in May. This level of enrichment is a technical step away from weapons-grade material, which is 90% enriched uranium.

The IAEA report also highlights that Iran and the agency have yet to agree on resuming inspections of sites affected by Israeli and U.S. airstrikes on June 13. The extent of disruption to Iran's nuclear program from these strikes remains unclear.

On July 2, Iranian President Masoud Pezeshkian enacted a law suspending cooperation with the IAEA, requiring any future inspections to be approved by Tehran's Supreme National Security Council.

IAEA Director General Rafael Grossi emphasized the urgency of resuming inspections, stating that technical modalities should be concluded without delay.

As of June 13, Iran's total enriched uranium stockpile was 9,874.9 kilograms, an increase of 627.3 kilograms since May. The IAEA has been unable to verify Iran's near bomb-grade stockpile for over two and a half months, which it called a matter of serious concern.

Negotiations between Iran and the IAEA are ongoing, with discussions held in Tehran on August 11 and plans to continue in Vienna in the coming days.

In response to Iran's actions, France, Germany, and the United Kingdom have initiated the process of reimposing sanctions, a move that could take effect in a month unless a diplomatic agreement is reached.
