TEHRAN, Aug 6: Iran vowed on Sunday to expand its atomic fuel work and warned that any UN sanctions aimed at halting its uranium enrichment would incur a painful riposte, possibly including a cut in oil exports.

Chief nuclear negotiator Ali Larijani said Iran would expand the number of atomic centrifuges it was running. Centrifuges enrich uranium by spinning it at supersonic speeds.

“We will expand nuclear technology at whatever stage it may be necessary and all of Iran’s nuclear technology including the (centrifuge) cascades will be expanded,” he told a news conference.

Such remarks flatly reject a UN Security Council resolution demanding Tehran halt its nuclear work by Aug 31 or face the threat of sanctions. The West fears Iran will use its atomic fuel in warheads.

Iranian officials, who argue they need enriched uranium only to run power stations, say the resolution was illegal and that Tehran has every right to produce fuel from the uranium ore it mines in its central deserts.

Larijani said the expansion of atomic work would be conducted under the supervision of the International Atomic Energy Agency but even that could be in question if Iran felt unfairly treated.

“We do not want to end the supervision of the agency, but you should not do anything to force Iran to do so,” he said.
