Since Hassan Rouhani became president, Iran has stopped expanding its uranium enrichment capacity, a UN inspection report showed on Thursday, in a potential boost for diplomacy to end Tehran’s nuclear dispute with the West.
The quarterly report by the International Atomic Energy Agency (IAEA) also said that since August no further major components had been added to a potential plutonium-producing reactor that worries the US and its allies.
The marked slowdown in the growth of activities of possible use in developing nuclear bombs may be intended to back up Rouhani’s warmer tone towards the West after years of worsening confrontation, and strengthen Tehran’s hand in talks with world powers due to resume on Nov. 20.
The six powers — the US, France, Germany, Britain, Russia and China — are pressing Iran to curb its nuclear program to ease fears that it may be seeking to develop nuclear weapons, a charge Tehran denies.
Iran halted a previously rapid increase in its capacity to refine uranium — which can fuel nuclear power plants, but also bombs if processed much more — “when their team changed” in August, a senior diplomat familiar with the IAEA report said, referring to Rouhani and his administration.
Yet Iran is still pressing ahead with its most sensitive nuclear activity, the enrichment of uranium to a fissile concentration of 20 percent, a relatively short technical step away from weapons-grade material, the report showed,
Israeli Prime Minister Benjamin Netanyahu — who strongly opposes any deal with Iran that does not dismantle its entire enrichment program — said he was “not impressed,” as the Islamic state did not need to expand its program.
“They’ve got enough facilities, enough centrifuges to develop and to complete the fissile material, which is at the core of an atomic bomb,” Netanyahu said.
Israel, believed to be the Middle East’s sole nuclear-armed power, has long warned it could use force to prevent Iran from gaining such weapons.
The Arak reactor, which Iran previously said it would start up in the first quarter of next year, but later postponed, is of great concern for Western powers as it could yield weapons-grade plutonium once it is operating.
France said during talks between Iran and world powers in Geneva last week that Tehran must suspend building Arak.
However, the IAEA report showed that Iran has “more or less frozen” construction of the heavy water reactor, the diplomat said, making clear he did not believe it would be up and running any time soon: “Major components are missing from the plant.”
The quarterly IAEA document was the first that included developments only since Rouhani took office on Aug. 3, prompting a diplomatic opening during which Iran and the world powers have made progress towards a possible nuclear accord.
It was issued the same week that Iran agreed to grant IAEA inspectors access to two nuclear-related facilities as part of a cooperation pact to resolve outstanding issues between the two, including suspicions of nuclear bomb research by Tehran.
“Iran has now taken two unilateral steps to show it wants a deal — it has stopped expanding its nuclear program and begun to provide more transparency,” Middle East expert Cliff Kupchan of risk consultancy Eurasia group said. This was “clever diplomacy — it puts the onus on the West to respond.”
