Drastical reduction its stock of enriched uranium which can be used for nuclear weapons was at the heart of the deal Iran reached in July with a group of six world powers.
Under its terms, Iran must cut its stockpile to around 300 kg and mothball most of the centrifuges that produce the enriched fuel. It must also remove the core of a heavy water reactor at Arak so it cannot be used to produce plutonium, another potential bomb-making source.

IAEA chief Yukiya Amano, responsible for verifying that Tehran has taken the necessary steps, said in an interview that it is "not impossible" that sanctions could be lifted in January.
