NEW YORK-Iran has produced enough material to make one nuclear weapon, The New York Times reported on Thursday, citing nuclear experts analysing a report by international inspectors. Information detailing Iran's progress was in an update from the International Atomic Energy Agency, which has been conducting inspections of Iran's main nuclear facility at Natanz. The report concluded that, as of earlier in November, Iran produced about 1,390 pounds of low-enriched uranium, the newspaper said. Several experts told the Times that amount was enough for a bomb, adding, that more work was needed to actually create the weapon. 'Not only would Tehran have to renege on its agreements and expel inspectors, it also would have to further purify the fuel and put it in a warhead design'. 'They clearly have enough material for a bomb', Richard Garwin, a nuclear physicist who helped invent the hydrogen bomb and has advised US officials, told the Times. 'They know how to do the enrichment. Whether they know how to design a bomb, well, that's another matter'. Iran says its nuclear programme is for peaceful purposes. However, the US and some of its Western allies insist that the actual purpose is to gain nuclear weapons-making capability. Israel has even threatened to destroy the Islamic Republic's nuclear facilities. The report also said in the Natanz plant was feeding uranium into about 3,800 centrifuges, the same number as in the agency's September quarterly report.
