VIENNA, Austria – The U.N. atomic watchdog agency revealed Friday that Iran received black market nuclear designs that diplomats say appear to be blueprints for the core of a nuclear warhead – a finding expected to be used by Washington and its allies in their push to have Tehran referred to the U.N. Security Council.
A senior U.S. diplomat called the development disturbing.
The revelations also came as Iran said it had begun converting a second batch of uranium into gas, a step that brings it closer to producing the enriched uranium used to either generate electricity or build bombs.
The State Department denounced Iran’s actions. “You’ve given the world cause for concern,” spokesman Adam Ereli said. “The international community doesn’t like what it sees, and it doesn’t like the kind of behavior that you’ve been exhibiting over the last several years.”
He urged Iran to be more forthcoming with the International Atomic Energy Agency at its 35-nation meeting next week. He said that if Tehran chooses to remain silent, it increases chances of becoming more isolated from the rest of the world.
Undersecretary of State Nicholas Burns flew to London on Thursday night for talks with European and Russian ministers.
The European Union, with U.S. support, has been calling on Iran to reimpose a freeze on conversion since August. But the nation’s top nuclear negotiator, Ali Larijani, told state TV the country had started converting the second batch of uranium.
“This job is done and the plant is continuing its activity,” Larijani said in an interview broadcast Friday.
One idea under consideration is to permit Iran to convert uranium but to move the enrichment process to Russia, thereby hopefully denying Iran the capacity to produce weapons-grade uranium for nuclear weapons. President Bush confirmed reports of U.S. approval of the compromise in a meeting Friday in South Korea with Russian President Vladimir Putin.
The IAEA said Iran received the detailed designs from the network run by Abdul Qadeer Khan, the father of Pakistan’s nuclear program. His network supplied Libya with information for its now-dismantled nuclear weapons program that included an engineer’s drawing of an atomic bomb.
The document given to Iran in 1987 showed how to cast “enriched, natural and depleted uranium metal into hemispherical forms,” said a confidential IAEA report.
IAEA officials refused to comment on the implications of the finding. But diplomats close to the agency said it appeared to be a design for the core of a nuclear warhead.
