IAEA says

Tehran: Israeli’s air strike caused significant damage to a major Iranian nuclear feature during the weekend aerial attack, according to the United Nations Atomic Watchdog, possibly establishing Iran’s uranium fuel cycle back for months. IAEA reported that there were several Israeli attacks against Iran’s uranium-transformation facility in Isfahan, 400 km south of Tehran, resulting in serious damage. It will be important to successfully knock the Isfahan as it is the only place to change uranium in feedstock used by Centrephus, which in turn separates the uranium isotopes required for nuclear power or bomb. IAEA said late Friday night that Israel has so far failed to damage Iran’s Fordo promotion complex, which has been buried about 1,640 feet inside a mountain. Similarly, efforts to destroy Iran’s primary enrichment facility in Natanz have been limited to surface structures, in which no detected for the heavy -strong underground promotion hall.
Even without destroying Iran’s ability to rich, Israel’s campaign has been some measured success after three days of bombing, said by experts. Without the ability to replace the new versions of Isfahan’s raw uranium, Iran’s ability to create additional amount of rich products will be frozen. And while Iran has sufficient reserves of materials, its capacity will be limited on its scale.
