Iran has produced enough enriched uranium to build one nuclear bomb with added purification, the 'New York Times' reports, citing nuclear experts' analysis of a report by the International Atomic Energy Agency (IAEA) in Vienna. The experts said that the 630 kilograms of nuclear material Iran now has would need to be refined and designed into a warhead, something Iran may not yet be capable of, the newspaper added. To take additional steps needed to produce a bomb, Iran would have to expel nuclear inspectors, a move that would violate its international agreements. "They clearly have enough material for a bomb," Richard L. Garwin, a nuclear physicist who helped invent the hydrogen bomb and has advised Washington for decades, was quoted by the newspaper as saying, adding, "They know how to do the enrichment. Whether they know how to design a bomb, well, that's another matter."
Iran has said it only wants to build fuel reactors to produce nuclear power; however some Iranian officials have in the past threatened to bar inspectors. US and IAEA officials estimated the country was not likely to break its international agreements until it has a bigger supply of uranium, the newspaper report. US intelligence services have projected that Iran could build a nuclear weapon between 2009 and 2015. An assessment released in December 2007 indicated that the country had suspended its formal nuclear-weapon program in 2003, but the enrichment process is one of the most difficult steps toward developing a nuclear bomb.
