The semi-official Mehr news agency reported the four-member team visited the heavily protected facility, carved into a mountainside south of Tehran. The tour marked the first independent examination of the site, but no results were expected until after the inspectors leave Iran later this week.
The review also coincides with the countdown to Iran’s expected decision on whether to accept a UN-brokered deal to process its nuclear fuel abroad – a plan designed to ease Western fears about Iran’s potential ability to produce weapons-grade material.
The disclosure last month of Iran’s second enrichment facility – known as Fordo after a village believed to have the largest percentage of fighters killed in the 1980-88 war with Iraq – raised international suspicion over the extent and aim of Tehran’s nuclear programme.
But Iran says that by reporting the existence of the site voluntarily to the UN’s nuclear watchdog, it “pre-empted a conspiracy” against Tehran by the US and its allies who were hoping to present the site as evidence that Iran was developing its nuclear programme in secret.
Iran also has promised to respond later this week on a UN-drafted proposal to have its nuclear fuel processed outside the country. Iran claims it only seeks peaceful reactors for research and energy.
Although Iran has not given its official answer on the proposed nuclear deal – discussed last week after talks in Vienna with the United States, France and Russia – there are increasing doubts that Iran’s leadership will come on board.
On Saturday, Parliament Speaker Ali Larijani claimed the West was trying to “cheat” Iran under the deal that would ship most of Iran’s uranium to Russia for reactor-ready enrichment.
Larijani, the country’s former nuclear negotiator, said Iran prefers to buy the nuclear fuel it needs for a reactor under construction that makes medical isotopes. He did not specifically address the fuel needs for Iran’s planned Russian-built full-scale reactor, but Russia is required to provide fuel as part of agreement to build it for Iran in the southern city of Bushehr. The reactor is nearly operational.
The four-member delegation from the International Atomic Energy Agency is led by Herman Nackaerts, director of IAEA’s division of operations department of safeguards. The inspectors are to stay three days in Iran.
