Iran has developed a new generation of centrifuges 15 times more powerful than those currently used to enrich uranium, atomic chief Ali Akbar Salehi said Monday.
Iran currently has nearly 19,000 centrifuges, including 10,000 of the so-called first generation being used to enrich uranium.
Some 1,000 second generation machines, three to five times more powerful, have been installed but are not in service.
Under the November deal, Iran cannot increase the number of its centrifuges.
Salehi did not say when the new centrifuges would become operational, but a first machine was to be delivered to a medical centre in Karaj, west of Tehran, “within two or three months.”
