IAEA Warns of Radiological Risk from Iran Strikes
The International Atomic Energy Agency (IAEA) is warning it “cannot rule out” a possible radiological release in Iran due to the proximity of military strikes to sensitive sites. While the agency has detected no incident so far, it is calling for immediate de-escalation and access for its inspectors.
The IAEA's warning follows satellite imagery confirming recent damage to the entrance buildings of Iran's underground Natanz Fuel Enrichment Plant. While the agency stated no radiological consequences are expected from this specific damage, the incident underscores the vulnerability of nuclear sites amid military conflict. The underground Fuel Enrichment Plant at Natanz had already been "severely damaged" in a previous conflict in June, according to the IAEA. Iran's nuclear program is decentralized across several key sites, each with a distinct purpose and risk profile. The Bushehr Nuclear Power Plant is an operational reactor, posing a high contamination risk from spent fuel if struck, potentially releasing radioactive materials like iodine-131 and cesium-137. Other major facilities include the deeply buried Fordow enrichment site, a uranium conversion facility in Isfahan, and the Arak heavy water reactor. A direct hit on an enrichment facility like Natanz or a conversion site like Isfahan carries risks of dispersing uranium isotopes. The primary danger from this material is if it is inhaled or ingested, posing both a radiological hazard from alpha particles and a chemical toxicity threat from compounds like uranium hexafluoride. The relationship between the IAEA and Iran has been fraught with tension, impacting the agency's ability to monitor the nuclear program. Iran suspended all cooperation with the IAEA after a 12-day war last year, before agreeing to restart inspections in September. This has led to what the agency calls a loss of "continuity of knowledge" regarding Iran's stockpile of highly enriched uranium. IAEA inspectors have recently returned to Iran, with a team present at the Bushehr site to oversee a fuel replacement. However, their broader access to sites, particularly those damaged in conflicts, remains a point of negotiation, with Iran citing safety and security concerns. The strikes have drawn a mixed international reaction, with Russia and China condemning the attacks, while other nations have expressed support for efforts to prevent Iran from obtaining a nuclear weapon. United Nations officials and the European Union have broadly called for restraint and a return to diplomacy to de-escalate the conflict and ensure nuclear safety. Attacks on nuclear facilities intended for peaceful purposes are considered a violation of the United Nations Charter and international law. IAEA Director General Rafael Grossi has repeatedly invoked past resolutions stating that such attacks could lead to "grave consequences" from a potential radioactive release.
