Iran’s Near-Weapons-Grade Uranium Stockpile Remains Accessible Amid Ongoing Conflict

IAEA Warns Iran Can Retrieve Buried Uranium at Isfahan
The International Atomic Energy Agency (IAEA) Director General Rafael Grossi told Bloomberg TV that the uranium material stored near the Isfahan Nuclear Technology Center after U.S.–Israeli airstrikes is “accessible if there’s a wish to go there.” Satellite imagery shows the bulk of the material still buried at the site where it was last observed in June 2025. IAEA inspectors have not accessed the location for ten months, and the agency stresses that any settlement without verification would be ineffective.
Background & Context
The Isfahan complex was struck during a 12-day war launched by Israel in June 2025 and again in the current U.S.–Israeli campaign that began in February 2026. The conflict has choked the Strait of Hormuz, a conduit for roughly one-fifth of global oil and liquefied natural gas shipments. Iran, a party to the Nuclear Non-Proliferation Treaty, has faced renewed scrutiny over its nuclear program, while the United States and Iran negotiate an interim arrangement to reopen Hormuz in exchange for lifting the U.S. blockade of Iranian ports.
Data & Statistics
- Approximately 9 kg of uranium enriched to 60 % purity is reported at the Isfahan site.
- The IAEA estimates roughly 200 kg of highly enriched uranium remains stored in tunnels there.
- At 60 % enrichment, the material is a short technical step from weapons-grade (90 %) and could theoretically enable the construction of up to ten nuclear bombs.
Official Statements & Responses
- IAEA: Grossi said inspectors have been unable to verify the material’s presence or the integrity of IAEA seals, and the agency is seeking access to Natanz and Fordo as well. He added that discussions with Russia and other states about removing the uranium are ongoing.
- United States: The White House confirmed talks on Iran’s proposal but reiterated “red lines,” including preventing Tehran from acquiring a nuclear weapon. White House Special Envoy Steve Witkoff and former President Donald Trump’s son-in-law Jared Kushner have been in contact with Grossi. President Trump asserted that the war aims to deny Iran a nuclear capability and noted Russian President Vladimir Putin’s offer to assist with the uranium issue.
- Iran: Tehran denied any intention to develop nuclear weapons and offered an interim deal to reopen the Hormuz Strait in exchange for the U.S. ending its port blockade. Iranian officials expressed willingness to negotiate.
Criticism, Opposition & Gaps
Analysts highlighted the IAEA’s ten-month inability to conduct on-site inspections as a major verification gap, raising doubts about the reliability of satellite-based assessments. The disparity between the reported 9 kg and 200 kg quantities underscores uncertainty about the true size of the stockpile. Critics argue that without physical access, any diplomatic arrangement risks overlooking undeclared material.
Verbatim Quotes
- “It is accessible if there’s a wish to go there,” — Rafael Grossi, IAEA Director General
- “An agreement without verification is an illusion.” — Rafael Grossi, IAEA Director General
- “We haven’t been able to inspect or to reject that the material is there and that the seals — the IAEA seals — remain there,” — Rafael Grossi, IAEA Director General
- “what’s going to be important is that that material leaves Iran” — Rafael Grossi, IAEA Director General
What’s Next
The IAEA seeks to resume inspections at Isfahan, Natanz and Fordo, while diplomatic channels explore either the removal of the enriched uranium or its dilution. Continued negotiations between Washington and Tehran will hinge on establishing a verification mechanism acceptable to all parties.
