Two senior diplomats said the transfer recently agreed by the U.S. and five other world powers that negotiated the nuclear deal with Iran foresees delivery of 116 metric tons (nearly 130 tons) of natural uranium. U.N. 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.
