Iran begins to build advanced centrifuges

Tehran:- Iran has begun working on infrastructure for building advanced centrifuges at its Natanz facility, Ali Akbar Salehi, the director of Iran's Atomic Energy Organisation said today.

Iran's nuclear activities would remain within the framework of the 2015 nuclear agreement with world powers, Salehi said.

Salehi also said Iran had developed infrastructure to produce electricity at Natanz.

France, Britain and Germany want to salvage the 2015 deal's core bargain of sanctions relief in exchange for restrictions on Tehran's atomic activities. Washington has reimposed sanctions against Tehran since quitting the deal last month, arguing Iran posed a security threat.

Iran has set out conditions to stay in the nuclear deal, including steps to safeguard trade with Tehran and guarantee Iranian oil sales. But it has also said it could resume its 20 percent uranium enrichment, which is banned under the deal.

Iran was developing infrastructure for building advanced centrifuges at its Natanz facility, Ali Akbar Salehi, director of Iran's Atomic Energy Organisation said in a news conference broadcast on state television.

Supreme Leader Ayatollah Ali Khamenei said on Monday he had ordered preparations for Iran to have greater enrichment capacity if the deal falls apart. Iran's nuclear agency said it would inform the UN nuclear watchdog on Tuesday the process to increase capacity had begun.

Salehi said this did not violate the nuclear deal but that it marked an increase in the pace of the nuclear programme.

"If we were progressing normally, it would have taken six or seven years, but this will now be ready in the coming weeks and months," he said.

Iran has also developed the capacity to produce electricity at Natanz, Salehi said, a site which lies around 300 kilometres (186 miles) south of Tehran.

The 2015 agreement allows Iran to continue 3.67 per cent uranium enrichment, far below the roughly 90 per cent threshold of weapons-grade. Before the deal was reached, Tehran enriched uranium to up to 20 per cent purity.

Salehi's comments Tuesday appeared to be a warning to the remaining signatories of possible consequences if the deal were to collapse. European powers still back the deal but have concerns over Iran's ballistic missile programme and its influence in the Middle East. Iran says the two issues are non-negotiable.

Salehi said Iran could not accept a "flawed" nuclear deal, nor could it adhere to the deal's restrictions while facing new sanctions. He reiterated previous statements by officials that Iran is prepared to significantly increase its nuclear activity if the deal falls apart.

"Then the situation will progress in a different way," Salehi said. "I hope there will never be a need to go back to that situation."

He also repeated Iran's position that its nuclear programme was for civilian purposes only.
