New intelligence on Iran nuke work: Diplomats

Last Updated: Tuesday, September 11, 2012 - 21:37

Vienna: The UN atomic agency has received new and significant intelligence over the past month that Iran has moved further toward the ability to build a nuclear weapon, diplomats have said.

They said that the intelligence shows that Iran has advanced its work on calculating the destructive power of an atomic warhead through a series of computer models that it ran sometime within the past three years.

The diplomats say the information comes from Israel, the United States and at least two other Western countries. The time-frame is significant because if the International Atomic Energy Agency decides that the intelligence is credible, it would strengthen its concerns that Iran has continued weapons work into the recent past and may be continuing to do so.

Because computer modeling work is normally accompanied by physical tests of the components that go into a nuclear weapons, it would also buttress IAEA fears outlined in detail in November that Tehran is advancing its weapons research on multiple fronts.

"You want to have a theoretical understanding of the working of a nuclear weapon that is then related to the experiments you do on the various components," said David Albright, whose Washington-based Institute for Science and International Security is a frequent go-to source on Iran for Congress and other US government branches.

"The two go hand-in-hand."

Such computer mock-ups typically assess how high explosives compress fissile warhead material, setting off the chain reaction that results in a nuclear explosion. The yield is normally calculated in kilotons.

Any new evidence of Iranian research into nuclear weapons is likely to strengthen the hand of hawks in Israel who advocate a military strike on Iran. They argue that Tehran is deliberately stalemating international efforts at engagement while continuing its clandestine weapons work.

Iran denies any interest in nuclear weapons and says suspicions that it ever tried to develop them are based on fabricated US, Israeli and other intelligence. At the same time, it has blunted IAEA efforts to investigate such claims for more than five years.

It also has scoffed at Western allegations that it is enriching uranium to make the core of nuclear warheads, saying it seeks only to create reactor fuel. But it refuses to accept offers of such fuel from abroad and is now producing material that is easier to turn into weapons-grade uranium than its main, lower-enriched stockpile.
