From The New York Times,October 23, 2009:
TEHRAN (Reuters) - Iran declined Friday to endorse proposals by the U.N. nuclear watchdog to help reduce Iran's stockpile of low-enriched uranium.
...The U.N. nuclear watchdog Wednesday presented a draft deal to Iran and three world powers for approval within two days to reduce Tehran's stockpile of low-enriched uranium, seen by the West as a nuclear weapons risk.
The three powers -- Russia, the United States and France -- have all signalled approval of the draft.
Western diplomats said the plan would require Tehran to send 1.2 tonnes of its known 1.5-tonne reserve of low-enriched uranium (LEU) to Russia and France by the end of the year.
The material would be converted into fuel for the Tehran medical reactor.
