That Tehran is enriching uranium up to 20% purity — a technical step from weapons-grade levels of 90% — with a new set of its most advanced centrifuges at a facility deep inside a mountain deals yet another blow to the already slim chances of reviving the accord.
Behrouz Kamalvandi, a spokesman for Iran’s Atomic Energy Organization, said uranium enriched to 20% was collected for the first time from advanced IR-6 centrifuges on Saturday. He said Iran had informed the UN nuclear watchdog about the development two weeks ago.
Centrifuges are used to spin enriched uranium into higher levels of purity. Tehran’s 2015 nuclear agreement with world powers had called for Fordo to become a research-and-development facility and restricted centrifuges there to non-nuclear uses.
Iran had previously told the IAEA that it was preparing to enrich uranium through a new cascade of 166 advanced IR-6 centrifuges at its underground Fordo facility. But it hadn’t revealed the level at which the cascade would be enriching. READ MORE
