The move was an effort to thwart the US from launching a raid to retrieve Tehran’s 440-pound stockpile of 60% highly enriched uranium believed to be buried there.
Iran booby-trapped the tunnels leading to its highly enriched uranium stockpile in recent weeks — in an apparent bid to stop the US from raiding its key nuclear site, a bombshell new report revealed.
The Islamic Republic planted explosive mines at tunnel entrances and deliberately collapsed passageways to its nuclear cache in the city of Isfahan, south of Tehran, five sources familiar with US intelligenceThe risky ground raid was ultimately scrapped, but may have given Tehran the incentive to conceal its nuclear assets, two of the sources said. An estimated 440 pounds of 60% enriched uranium — which is only a short technical step from a nuclear weapon — is stored in the tunnel complex, the only major nuclear site that appears to have survived largely intact afterThat amount represents more than half of the Iranian regime’s total stockpile of highly enriched uranium, the IAEA said.
Iran also reportedly intentionally sealed some of its tunnels at Isfahan to block access to nuclear materials over the last few weeks. , requires Tehran to turn over its enriched uranium so it can be destroyed on site and transported out of the country. An uranium conversion facility is just outside the city of Isfahan, where most of the stockpile is believed to be stored.
But the new barriers mean the tunnels will need to be excavated and de-mined, complicating the removal of delicate uranium even for the Iranians, several of the sources said.
“I would worry that Iran would claim that some portion of the highly enriched uranium was irretrievable,” Scott Roecker, former head of the National Nuclear Security Administration’s Office of Nuclear Material Removal, told CNN. “We wouldn’t have full confidence that Iran couldn’t retain access to it at some point in the future. ”

IAEA Demands Iran Halt Enrichment and Grant Full Inspections in New ResolutionThe International Atomic Energy Agency passed a resolution backed by the US and other nations, demanding Iran suspend all uranium enrichment activities and grant unrestricted access to nuclear sites. The move follows years of Iranian non-compliance and restricted inspections, heightening proliferation concerns. Iran dismissed the resolution as political. IAEA Chief Rafael Grossi warned that lack of access since 2025 airstrikes leaves 440 kg of highly enriched uranium unaccounted for, enough for multiple warheads. Ongoing US-Iran negotiations and geopolitical divisions complicate the situation.
