IAEA Report Confirms Iran’s Enriched Uranium Stockpile at 9,874.9 kg as of June 13, 2025

The International Atomic Energy Agency (IAEA) has reiterated that Iran’s stockpile of enriched uranium totaled 9,874.9 kilograms as of June 13, 2025, the day Israeli military strikes began targeting Iranian nuclear sites. This figure includes 440.9 kilograms of uranium enriched to 60%, a 32.3 kg increase since the IAEA's May 2025 report. The 60% enriched uranium, while not yet weapons-grade, is a critical threshold, as further enrichment to 90% could produce material suitable for nuclear weapons.

The IAEA report highlights that approximately 42 kg of 60% enriched uranium is theoretically sufficient to produce one atomic bomb if further enriched. However, the agency has not verified Iran's stockpile since June 13 due to security risks and the suspension of on-site inspections following the attacks. Iran's parliament later passed a law suspending cooperation with the IAEA, complicating efforts to verify compliance with its safeguards obligations under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT).

The IAEA has expressed concern over the lack of access to damaged sites, including Natanz, Fordow, and Esfahan, where attacks caused significant infrastructure damage but no reported radiological releases according to the IAEA. Director General Rafael Grossi emphasized the need for "urgent" resumption of inspections to ensure transparency and prevent diversion of enriched uranium as stated in a press release.

Geopolitical tensions remain high, with European nations initiating a "snapback" process to reimpose sanctions on Iran unless diplomatic progress is made. The IAEA has called for de-escalation and renewed dialogue to facilitate inspections and verify Iran's nuclear activities. Grossi reiterated that attacks on nuclear facilities—such as the Bushehr Power Plant—pose severe risks to regional and global safety.

As of February 2026, the IAEA continues to advocate for a diplomatic resolution to ensure Iran's nuclear program remains peaceful and transparent. The agency's ability to provide credible assurances depends on resumed cooperation and unimpeded access to all relevant sites.
