Iran has started the process of enriching uranium to 60% fissile purity at an “above-ground facility” at its Natanz Enrichment Plant in Natanz, the UN nuclear watchdog says in a statement to Reuters, confirming earlier announcements made by Iranian officials.
“The Agency today verified that Iran had begun the production of UF6 enriched up to 60% U-235 by feeding UF6 enriched up to 5% U-235 simultaneously into two cascades of IR-4 centrifuges and IR-6 centrifuges at the Natanz Pilot Fuel Enrichment Plant,” the International Atomic Energy Agency says.
A bomb early on April 11 blew up the main and backup power supply to the underground enrichment facility. It caused damage to various kinds of the 6,000 centrifuges there and set back enrichment for 6-9 months, according to Israeli and American reports. However, Iran on Saturday released video purporting to show the underground facility resuming activity.
