Iran's Enriched Uranium Stockpile: Concerns Over Isfahan Facility
3/10/2026, 1:57:25 AM
Current Status of Iran's Uranium Enrichment
On March 9, 2026, Rafael Grossi, the Director General of the International Atomic Energy Agency (IAEA), reported that nearly half of Iran's uranium enriched to 60% purity, which is close to weapons-grade, is likely stored in a tunnel complex at Isfahan. This facility has reportedly sustained minimal damage from attacks carried out by Israel and the United States in June 2025. Grossi indicated that the Isfahan complex is the primary location for this stockpile, with estimates suggesting it contained over 200 kg of 60% enriched uranium during the last inspection.
The IAEA's assessment indicates that Iran had approximately 440.9 kg of 60% enriched uranium before the June attacks, which, if further enriched, could yield enough fissile material for up to ten nuclear weapons. Grossi emphasized that there has been no observable movement of this material, suggesting it remains at the Isfahan site.
Background on Nuclear Tensions
The heightened scrutiny of Iran's nuclear program stems from ongoing geopolitical tensions, particularly between Iran, Israel, and the United States. The U.S. and Israel have cited Iran's nuclear advancements as a justification for military actions, asserting that Iran is approaching the capability to produce nuclear weapons. Despite these claims, the IAEA has stated that there is no credible evidence of a coordinated nuclear weapons program in Iran.
Official Statements & Responses
In his remarks, Grossi noted, "The widespread assumption is that the material is still there," highlighting the lack of communication from Iran regarding the status of its enriched uranium since the June attacks. He also pointed out that the IAEA has not been allowed to return to inspect the bombed facilities, which raises concerns about transparency in Iran's nuclear activities.
Criticism & Opposition
Critics of Iran's nuclear program, including officials from Israel and the U.S., argue that the continued enrichment activities pose a significant threat to regional and global security. They contend that Iran's actions undermine international agreements aimed at preventing nuclear proliferation. Conversely, Iranian officials maintain that their nuclear program is for peaceful purposes and assert their right to enrich uranium under international law.
Conflicting Reports & Gaps
While the IAEA has confirmed the presence of enriched uranium at Isfahan, there are discrepancies regarding the total amounts and the status of other facilities. Reports indicate that uranium enrichment plants at Natanz and Fordow were either destroyed or severely damaged during the June attacks, yet Grossi mentioned that some enriched uranium may still exist at Natanz.

- “What we believe is that Isfahan had until our last inspection a bit more than 200 kg, maybe a little bit more than that, of 60% uranium,” — Rafael Grossi, IAEA Director General
- “There is an amount (of 60% uranium) in Natanz also, which we believe is still there,” — Rafael Grossi, IAEA Director General
The situation surrounding Iran's enriched uranium stockpile continues to evolve, with significant implications for international security and diplomatic relations in the region.
