Iran nuclear chief insists on enrichment ahead of talks

Iran's atomic agency chief insisted today on Tehran's demands for increased uranium enrichment, days before the resumption of thorny talks with world powers in Geneva.
Ali Akbar Salehi, a former foreign minister and ex-nuclear negotiator for the Islamic republic, said that within eight years the country would need 12 times more enriched uranium than at present.
Iran's level of uranium enrichment -- the process that produces atomic fuel -- has been a key stumbling block in reaching a deal with the P5+1 powers (Britain, China, France, Russia, the United States plus Germany) on Tehran's contentious nuclear programme.
"We currently produce 2.5 tons but will need 30 tons eventually," Salehi, head of the Iranian Atomic Energy Organisation, was quoted as saying by official news agency IRNA.

"They refuse... And ask that we reduce the number of centrifuges (the machines that enrich uranium)," Salehi said.
"We must have that right in eight years... We are ready to do this in stages. They can set the first step but we want to set the last step."

With a comprehensive nuclear deal at stake by a June 30 deadline, the negotiations have stalled on key issues.
Big gaps remain on uranium enrichment and the time it will take to lift extensive international sanctions imposed on Iran as punishment for its nuclear activities.
Following a preliminary agreement in November 2013, two deadlines for a final deal have been missed with talks failing to pin down hard details on what an approved Iranian nuclear programme would look like.

Under the interim deal, Iran's stock of fissile material has been diluted from 20 per cent enriched uranium to five per cent in exchange for limited sanctions relief.
This would push back the "breakout capacity" to make an atomic weapon, which Iran denies pursuing.
