Iran's Nuclear Slowdown Puts Off War For Now

Expanding Uranium Capacity Could Bring Tensions Back

A slowdown in Iran’s accumulation of its most sensitive nuclear material may have helped put off the threat of a new Middle East war for now, but Tehran’s expanding uranium-enrichment capacity suggests any relief could be short-lived.

By dedicating a big part of its higher-enriched uranium to make civilian reactor fuel, Iran is removing it from a stockpile that could be used to make nuclear weapons if refined further and which would otherwise have grown faster.

This may explain why Israel - assumed to be the region’s only nuclear-armed state - recently signalled that an attack was not imminent, after months of speculation that it might be.

But the trend that has emerged in U.N. nuclear watchdog reports on Iran this year could yet be reversible, proliferation experts say: the material can be converted back to uranium gas as long as it has not been introduced into a working reactor.

Doing so “would take a bit of time, but not more than a month or two, using technology the Iranians have already demonstrated that they have mastered,” a Western envoy said.

In addition, Iran’s rapid installation of new centrifuges - the machines that enrich uranium by spinning at supersonic speed - in an underground site gives it the capability to rapidly increase output, analysts say.

Even so, another Vienna-based diplomat said the fact that Iran was making reactor fuel from some of its higher-grade uranium was positive in itself. “Hopefully it could help us buy some time for diplomacy,” the diplomat said.

The question of when and how quickly Iran might be able to assemble a nuclear weapon if it chose to do so is hotly debated in the West because it could influence any decision by Israel to launch military strikes against the Islamic Republic.

The United States and its allies are especially watching how much uranium refined to a fissile concentration of 20 percent Iran is amassing, as this is a short technical step away from the 90 percent level needed for nuclear weapons.
