Iran has exceeded a limit on its enriched uranium reserves set by a 2015 nuclear deal.
The International Atomic Energy Agency “verified on July 1 that Iran’s total enriched uranium stockpile exceeded 300 kilograms”, a spokesperson said, shortly after Tehran announced it had crossed the limit in retaliation to new US sanctions.
The International Atomic Energy agency (IAEA) said that its inspectors were verifying whether Iran had accumulated more enriched uranium than allowed.
Enriching uranium to a low level of 3.6% fissile material is the first step in a process that could eventually allow Iran to amass enough highly-enriched uranium to build anuclear warhead.
Last Wednesday, the IAEA verified that Iran had roughly 200kg of low-enriched uranium, just below the deal’s 202.8kg limit, three diplomats
who follow the agency’s work told Reuters. A quantity of 300kg of UF6 (uranium hexafluoride) corresponds to 202.8kg of LEU.
After talks on Friday in Vienna, Iran said European countries had offered too little in the way of trade assistance to persuade it to back off from its plan to breach the limit, a riposte to US President Donald Trump’s decision last year to quit the deal and reimpose economic sanctions.
