VIENNA—A landmark nuclear deal with Tehran moved closer to implementation Monday, with U.S. Secretary of State John Kerry announcing that tons of enriched uranium that could potentially be turned to use in atomic arms were on a ship heading from Iran to Russia.
Kerry hailed the development as “one of the most significant steps Iran has taken toward fulfilling its commitments” under the July 14 nuclear agreement, in comments that expanded on information The Associated Press received from a senior Russian diplomat earlier in the day.
That envoy, who spoke on condition of anonymity because he wasn’t authorized to be cited by name, said Iran had permitted Russia to take possession of and ship out most of its low-enriched uranium. Low-enriched uranium is suitable primarily to generate nuclear power and needs substantial further enrichment for use in the core of a nuclear warhead.
But Kerry said that the shipment also included the remaining stock of Iranian uranium that already had been enriched to higher levels, just a technical step away from what is needed to form the fissile core of a nuclear bomb.
The July 14 deal aims to reduce Iran’s ability to make nuclear weapons—something Tehran says it has no interest in.
Under the agreement, Iran committed to shipping out all except 300 kilograms (about 650 pounds) of its low-enriched uranium and to either export the uranium it has that is enriched to near 20 percent, process it into low-enriched uranium or turn it into fuel plates to power a research reactor.
