nuclear centrifuges

The New York talks among senior foreign ministry officials from the six powers and Iran are taking place on the sidelines of this week's annual gathering of world leaders at the U.N. General Assembly. The number of nuclear centrifuges has emerged as the principal sticking point in negotiations, which are expected to continue in New York until at least September 26. Centrifuges are machines that spin at supersonic speed to increase the ratio of the fissile isotope in uranium. Low-enriched uranium is used to fuel nuclear power plants, Iran's stated goal, but can also provide material for bombs if refined much further, which the West fears may be Iran's latent goal.
