IAEA on Iran - detailed
Posted: 19th June 2025
Following Friday’s attacks on nuclear sites in the Islamic Republic of Iran, the military conflict continues. As I reported to the IAEA’s Board of Governors and then to the UN Security Council last Friday, the IAEA is monitoring the situation very carefully. Our Incident and Emergency Centre has been up and running 24/7 from the start, ascertaining the status of Iran’s nuclear facilities and the level of radiation at relevant sites through constant communication with Iranian authorities. The IAEA is ready to respond to any nuclear or radiological emergency within an hour. Based on information available to the IAEA, the following is the current situation at Iran’s nuclear sites. There has been no additional damage at the Natanz Fuel Enrichment Plant site since the Friday attack, which destroyed the above-ground part of the Pilot Fuel Enrichment Plant, one of the plants at which Iran was producing uranium enriched up to 60% U-235. Electricity infrastructure at the facility, which included an electrical sub-station, a main electric power supply building, and emergency power supply and back-up generators, was also destroyed. There has been no indication of a physical attack on the underground cascade hall containing part of the Pilot Fuel Enrichment Plant and the main Fuel Enrichment Plant. However, the loss of power to the cascade hall may have damaged the centrifuges there. The level of radioactivity outside the Natanz site has remained unchanged and at normal levels, indicating no external radiological impact to the population or the environment from this event.
