Any attempt to import such a large amount of uranium ore would be in violation of those sanctions, which ban exports to the Islamic Republic of all items, materials, equipment, goods and technology that could contribute to its enrichment activities. In addition, transfers of uranium ore in quantities greater than 500 kilograms
-- 1,100 pounds -- annually are subject to close scrutiny by the Nuclear Suppliers Group of countries exporting atomic technology and materials. Tehran still has hundreds of tons of uranium hexafluoride -- the gas that is spun by centrifuges into enriched uranium. But its stockpile of uranium oxide, from which the gas is derived, is thought to be rapidly diminishing. The IAEA believes that Iran's rapidly expanding enrichment program has been built on 600 tons of uranium oxide imported from South Africa during the 1970s as part of plans by the former regime to build a network of nuclear reactors. The Washington-based Institute for Science and International Security said earlier this year that, based on 2008 IAEA statistics, Iran had already used up close to three-quarters of its South African supply. In a November report, the IAEA noted that Iran had stopped producing uranium gas from yellowcake in early August and said Iranian officials had notified the agency that the production facility was down for maintenance. David Albright, head of the Institute for Science and International Security, said Tuesday that the facility at the city of Isfahan had produced very little uranium gas for about a year. "They said it was closed for maintenance but the reality is they probably ran out of uranium," he said. Kazakhstan is among the world's three top producers of uranium, accounting for more than 8,500 tons last year. Iran, in contrast is producing an estimated 20 tons a year
-- far too little to power even one large reactor let alone the network it says it wants to put in place. Experts say it has amassed enough low enriched uranium to build at least two nuclear warheads, should it choose to. Albright estimated that Tehran theoretically could produce about 150 such weapons from 1,350 tons of yellowcake, as specified in the intelligence report, but said that was not necessarily why Iran wanted the material. "They want to have a civilian nuclear program but on the other hand they want to have nuclear weapons capability and they are willing to risk international sanctions," he said. Tehran built its nuclear program on purchases from the black market, with its present workhorse centrifuge based on the same basic model that it purchased from the illicit nuclear network of Pakistani scientist A.Q. Khan in the 1980s. "Their modus operandi is smuggling and that continues," said Albright, alluding to numerous instances of Iranian attempts to import equipment banned by the U.N. Security Council that have surfaced from the time its secret program was discovered seven years ago to the present. Adding to concerns, Iran has recently announced it plans 10 new enrichment plants. It belatedly revealed that it had been working on a secret facility in September, in an action Western officials describe as pre-emptive and driven by fears it was about to be found out.
