State TV quoted Iran’s nuclear chief Ali Akbar Salehi as claiming that Iran has decided to not put 1,000 second generation centrifuges into operation at one of its nuclear fuel enrichment sites. Salehi also said Iran currently has 19,000 operating centrifuges, and is now developing third and fourth generation-type centrifuges, and that Tehran is in discussions with Moscow over the construction of four new nuclear power plants in Iran.
