Iran Said Nearing Enrichment of Uranium

Iran plans to process tons of raw uranium and restart its centrifuges -- two activities that can be used to make nuclear warheads, the U.N. atomic watchdog agency and diplomats said Wednesday.  The United States -- which accuses Tehran of running a weapons program -- said the revelations provided further evidence Iran's nuclear activities pose "a threat to international peace and security." A confidential report by the International Atomic Energy Agency said it had been informed that Iran planned to process more than 40 tons of uranium into uranium hexafluoride. Uranium hexafluoride is spun in centrifuges to produce enriched uranium, which in turn can be used to generate power or make nuclear warheads, depending on the degree of enrichment. [more and [more ]
