Iran has built a new generation of centrifuges which are currently undergoing technical tests, the new head of Iran's Atomic Energy Organization Ali Akbar Salehi said on Tuesday.
"Iranian scientists have made new generation centrifuges that are currently undergoing necessary tests," he told a news conference, according to the official news agency IRNA.
According to a recent report issued by the International Atomic Energy Agency (IAEA), Iran has increased the number of operational centrifuges at its nuclear sites to 8,308, despite decreasing uranium production.
The IAEA said the large amount of centrifuges will allow Iran to expand its uranium production should it choose to do so.
Asked about the possibility of an Israeli attack on Iran, Salehi said, "The Zionist entity is in no position to take such a step," adding that Tehran was working to improve its defense systems to better protect the nuclear facilities.
Salehi spoke ahead of next week's talks between Iran and the six world powers (five permanent members of the UN Security Council - China, France, Russia, the United States and Britain - plus Germany), and said Tehran's representatives will not discuss the nuclear program during the negotiations.
The West suspects Iran is seeking the means to produce bombs, not just fuel for nuclear power plants as it says.
