Iran has increased its stockpile of uranium enriched to near weapons-grade levels, according to a confidential report released on Monday by the United Nations‘ nuclear watchdog. The report by the International Atomic Energy Agency (IAEA) noted that as of May 11, Iran possesses 142.1 kilograms of uranium enriched up to 60 percent. This marks an increase of 20.6 kilograms since the last IAEA report in February.
Uranium enriched to 60 percent is just a short step away from the 90 percent enrichment necessary for weapons-grade material. The IAEA has stated that if further enriched, around 42 kilograms of uranium enriched to 60 percent could theoretically produce one nuclear weapon.
Additionally, the report indicated that Iran‘s overall stockpile of enriched uranium stands at 6,201.3 kilograms, which has grown by 675.8 kilograms since the last report. While Iran insists its nuclear program is for peaceful purposes, IAEA chief Rafael Mariano Grossi has highlighted that Tehran now has enough near-weapons-grade uranium to produce multiple nuclear bombs if it chooses to do so. He also acknowledged that the U.N. agency cannot guarantee that some of Iran’s centrifuges have not been used for clandestine enrichment.
Following the death of Iran’s President Ebrahim Raisi and Foreign Minister Hossein Amirabdollahian in a helicopter crash, the IAEA’s talks with Tehran have stalled. Iran had initially agreed to technical negotiations with the IAEA on May 20, but the crash disrupted these plans. Iran has since expressed willingness to continue discussions at a later date.
The IAEA emphasized that comprehensive access to Iran’s nuclear program remains essential for effective verification, a sentiment echoed by Grossi, who “deeply regrets” Iran’s decision to bar inspectors.
