“We are aware of their sensitiveness toward the Fordo facility and those centrifuges,” Rouhani said in a live televised address. “At the same time, we cannot tolerate unilateral fulfillment of our commitments and no commitment from their side”
The International Atomic Energy Agency, the United Nations’ nuclear watchdog now monitoring Iran’s compliance with the deal, declined to comment on Iran’s announcement. The European Union on Monday called on Iran to return to the deal, while the White House sanctioned members of Supreme Leader Ayatollah Ali Khamenei’s inner circle as part of its maximalist campaign against Tehran.
Fordo sits some 25 kilometers (15 miles) northeast of Qom, a Shiite holy city and the site of a former ammunition dump. Shielded by the Alborz Mountains, the facility also is ringed by anti-aircraft guns and other fortifications. It is about the size of a football field, large enough to house 3,000 centrifuges.
Iran acknowledged Fordo’s existence in 2009 amid a major pressure campaign by Western powers over Tehran’s nuclear program. The West feared Iran could use its program to build a nuclear weapon; Iran insists the program is for peaceful purposes.
The centrifuges at Fordo are IR-1s, Iran’s first-generation centrifuge. The nuclear deal allowed those at Fordo to spin without uranium gas, while allowing up to 5,060 IR-1s at its Natanz facility to enrich uranium.
Rouhani said Tuesday that the centrifuges at Fordo would be injected with gas on Wednesday. He did not say did not say whether the centrifuges would produce enriched uranium.
However, Rouhani stressed the steps taken so far, including going beyond the deal’s enrichment and stockpile limitations, could be reversed if Europe offers a way for it to avoid U.S. sanctions choking off its crude oil sales abroad.
“We should be able to sell our oil,” Rouhani said. “We should be able to bring our money” into the country.
The 2015 nuclear deal, which saw Iran limit its enrichment in exchange for the lifting of economic sanctions, called for Fordo to become “a nuclear, physics and technology center.” Rosatom did not immediately respond to a request for comment about its work there.
Russia’s Deputy Foreign Minister Sergei Ryabkov said the joint Russian-Iranian project at Fordo would not be affected by Tehran’s latest move.
“We intend to continue to implement it,” Ryabkov said in remarks carried by Russian news agencies.
Dmitry Peskov, a spokesman for Russian President Vladimir Putin, said Moscow wants the nuclear deal to survive though it understood Iran’s anger over the “unprecedented and illegitimate sanctions against” it.
Rouhani’s announcement came after Ali Akhbar Salehi, the head of the Atomic Energy Organization of Iran, said Monday that Tehran had doubled the number of advanced IR-6 centrifuges operating in the country to 60.
A centrifuge enriches uranium by rapidly spinning uranium hexafluoride gas. An IR-6 centrifuge can produce enriched uranium 10 times faster than an IR-1, Iranian officials say.
Iranian scientists also are working on a prototype called the IR-9, which works 50-times faster than the IR-1, Salehi said.
As of now, Iran is enriching uranium up to 4.5%, in violation of the accord’s limit of 3.67%. Enriched uranium at the 3.67% level is enough for peaceful pursuits but is far below weapons-grade levels of 90%. At the 4.5% level, it is enough to help power Iran’s Bushehr reactor, the country’s only nuclear power plant. Prior to the atomic deal, Iran only reached up to 20%.
Tehran has gone from producing some 450 grams (1 pound) of low-enriched uranium a day to 5 kilograms (11 pounds), Salehi said. Iran now holds over 500 kilograms (1,102 pounds) of low-enriched uranium, Salehi said. The deal had limited Iran to 300 kilograms (661 pounds).
The collapse of the nuclear deal coincided with a tense summer of mysterious attacks on oil tankers and Saudi oil facilities that the U.S. blamed on Iran. Tehran denied the allegation, though it did seize oil tankers and shoot down a U.S. military surveillance drone.
