• Iranian uranium output decreases

  INTENDED EFFECT? International sanctions could be having an effect as the country’s production capacity is on the rise, but enriched uranium output is falling

  Iran’s output of enriched uranium is stagnating even as its production capacity increases, a sign that Tehran may be running out of the ore needed to make nuclear fuel, diplomats said.

  If so, it could mean that international sanctions to slow if not stop Iran’s nuclear program are taking hold.

  The diplomats, speaking on condition of anonymity, emphasized Tuesday the possibility that Iran was running short of uranium oxide was only one of several possible explanations for why it had not substantially upped its production of enriched uranium since May.

  But they said it seemed unlikely the Islamic Republic had deliberately decided to curb production. They said that over the past three months the country has expanded its processing capabilities by installing and running hundreds more of the centrifuges used to enrich uranium.

  The UN Security Council has imposed sanctions against Iran three times since 2006 for its refusal to freeze uranium enrichment.

  The sanctions grew from fears that Iran is using the pretext of building a peaceful nuclear energy program as a guise to eventually make weapons-grade enriched uranium.

  The country has also been placed on an international watch list to help limit the importation of nuclear materials, which could make it difficult to procure enough uranium oxide to feed its enrichment program.

  The International Atomic Energy Agency (IAEA) and independent experts believe that Iran’s rapidly expanding uranium enrichment program has been built on 600 tonnes of so-called “yellowcake” or uranium oxide imported from South Africa during the 1970s. The material was procured as part of ambitious plans by the former regime of Shah Mohammad Reza Pahlavi to build a network of nuclear reactors to generate power.

  Iran denied it was running out of yellowcake.

  “It is not true,” said Ali Asghar Soltanieh, Tehran’s chief delegate to the IAEA, while adding that he could not make a substantial comment before the agency publishes its next report on his country’s nuclear program sometime this week.

  “This is a technical project with its ups and downs,” he said when asked whether output was stagnating. “But everything is going according to plan.”

  At the US State Department, spokesman Ian Kelly declined to comment, except to say that the US remains intent on stopping Iran from getting a nuclear weapon.

  “We are very concerned about the refusal of Iran to adhere to its international obligations,” Kelly said.

  The spokesman said the administration of US President Barack Obama would comment once the formal IAEA report is available.

  In the enrichment process, uranium oxide is processed into uranium hexafluoride, which then is spun and re-spun to varying degrees of enrichment, with low enriched uranium used for nuclear fuel and upper-end high-enriched uranium for nuclear weapons.

  While Iran has built a large stockpile of uranium hexaflouride, it would not be able to replenish its supply if it is running out of ore. That could account for any decision to stop expanding output at Natanz, its cavernous underground enriching facility, in an effort to use up the supply of uranium gas more slowly.

  The existence of a secret Iranian enrichment program built on black market technology was revealed seven years ago. Since then the country has continued to expand the program with only a few interruptions as it works toward its aspirations of a 50,000-centrifuge enrichment facility at Natanz.

  In its last report on Iran in June, the IAEA said that nearly 5,000 centrifuges were operating at Natanz by May. Diplomats said on Tuesday that had expanded to about 6,000 of the machines by last month.

  The Washington-based Institute for Science and International Security has estimated that even when using the 5,000-centrifuge figure as a basis, Iran could accumulate enough material to produce weapons-grade uranium for two warheads by next February.

  While Iran continues to enrich uranium despite the UN sanctions, it is believed to depend on rapidly diminishing outside sources of uranium oxide, with domestic mining yielding only relatively small quantities of inferior ore.
