Iran installing centrifuges at N-plant: IAEA

February 22, 2013 - 5:01:30 am

VIENNA: Iran has begun installing advanced centrifuges at its main uranium enrichment plant, a UN nuclear report said yesterday, a defiant step likely to anger world powers ahead of a resumption of talks with Tehran next week.

In a confidential report, the International Atomic Energy Agency (IAEA) said 180 so-called IR-2m centrifuges and empty centrifuge casings had been hooked up at the plant near the central town of Natanz. They were not yet operating.

If launched successfully, such machines could enable Iran to significantly speed up its accumulation of material that the West fears could be used to devise a nuclear weapon. Iran says it is refining uranium only for peaceful energy purposes.

The deployment of the new centrifuges underlines Iran’s continued refusal to bow to Western pressure to curb its nuclear programme, and may further complicate efforts to resolve the dispute diplomatically without a spiral into Middle East war.

Six world powers and Iran are due to meet for the first time in eight months in Kazakhstan on February 26 to try again to break the impasse but analysts expect no real progress toward defusing suspicions of an Iranian quest for nuclear weapons capability.

In a more encouraging sign for the powers, however, the IAEA report said Iran in December resumed converting some of its uranium refined to a fissile concentration of 20 percent to powder for the production of reactor fuel.

That helped restrain the growth of Iran’s higher-grade uranium stockpile since the previous report in November, a development that could buy more time for diplomacy and delay possible Israeli military action.

The report said Iran had increased to 167kg its stockpile of 20 percent uranium — a level it says it needs to make fuel for a Tehran research reactor but which also takes it much closer to weapons-grade material if processed further.

One diplomat familiar with the report said this represented a rise of about 18-19 kg since the November report, a notable slowdown from the previous three-month period when the stockpile jumped by nearly 50 percent after Iran halted conversion.

About 240-250 kg of 20 percent enriched uranium is needed for one atomic bomb if refined to a high degree.

Israel, which has warned it might bomb arch-enemy Iran’s nuclear sites as a last resort, last year gave a rough deadline of mid-2013 as the date by which Tehran could have enough higher-grade uranium to produce a single atomic bomb. But a resumption of conversion, experts say, means the Israeli “red line” for action can be postponed. Iran resumed converting higher-grade enriched uranium for fuel production in December and had since fed 28.3 kg of the material for this stated purpose, the report said.
