VIENNA (AP) — Iran is to receive a huge shipment of natural uranium from Russia to compensate it for exporting tons of reactor coolant, diplomats say, in a move approved by the outgoing US administration and other governments seeking to keep Tehran committed to a landmark nuclear pact.
Two senior diplomats said the transfer recently agreed by the US and five other world powers that negotiated the nuclear deal with Iran foresees delivery of 116 metric tons (nearly 130 tons) of natural uranium. UN Security Council approval is needed but a formality, considering five of those powers are permanent Security Council members, they said.
Uranium can be enriched to levels ranging from reactor fuel or medical and research purposes to the core of an atomic bomb. Iran says it has no interest in such weapons and its activities are being closely monitored under the nuclear pact to make sure they remain peaceful.
Tehran already got a similar amount of natural uranium in 2015 as part of negotiations leading up to the nuclear deal, in a swap for enriched uranium it sent to Russia. But the new shipment will be the first such consignment since the deal came into force a year ago.
The diplomats, whose main focus is Iran’s nuclear program, demanded anonymity Monday because they are not allowed to discuss the program’s confidential details.
They spoke ahead of a meeting this week in Vienna of representatives of Iran, the United States, Russia, China, Britain, France and Germany to review Iranian complaints that the U.S. was reneging on sanctions relief pledges included in the nuclear deal.
The natural uranium agreement comes at a sensitive time. With the incoming US administration and many US lawmakers already skeptical of how effective the nuclear deal is in keeping Iran’s nuclear program peaceful over the long term, they might view it as further evidence that Tehran is being given too many concessions.
The diplomats said any natural uranium transferred to Iran after the deal came into effect would be under strict surveillance by the UN’s International Atomic Energy Agency for 25 years after implementation of the deal.
They said Tehran has not said what it would do with the uranium but could choose to store it or turn it into low-enriched uranium and then export it for use as reactor fuel.
Despite present restrictions on its enrichment program, the amount of natural uranium is significant should Iran decide to keep it in storage, considering its potential uses once some limits on Tehran’s nuclear activities start to expire in less than a decade.
David Albright, whose Institute of Science and International Security often briefs US lawmakers on Iran’s nuclear program, says the shipment could be enriched to enough weapons-grade uranium for more than 10 simple nuclear bombs, “depending on the efficiency of the enrichment process and the design of the nuclear weapon.”
The swap is in compensation for the 70 metric tons (77 tons) of heavy water exported by Iran to the United States, Russia and Oman since the nuclear agreement went into effect.
Heavy water is used to cool a type of reactor that produces more plutonium than reactors cooled by light water. Like enriched uranium, plutonium can be turned into the fissile core of a nuclear weapon.
