VIENNA (Reuters/AFP) - The UN nuclear watchdog on Wednesday handed Iran and world powers a draft deal for approval within two days to reduce Tehrans stockpile of enriched uranium, seen by the West as a nuclear weapons risk. The agreement was brokered after crunch talks between Iran, Russia, the United States and France, and has been sent to the capitals for final approval, said Mohamed ElBaradei, the head of the International Atomic Energy Agency (IAEA). Iran declined to say if it would endorse the plan, which Western diplomats said 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 for conversion into fuel for a nuclear medicine facility in Tehran. Irans envoy to the IAEA hinted it may seek amendments that diplomats suggested could snarl or kill the deal, because of 'red lines set by the powers to establish confidence Tehran does not seek to acquire nuclear weapons. We have to thoroughly study this text and ... come back and reflect our opinion and suggestions or comments in order to have an amicable solution at the end of the day, Iranian Ambassador Ali Asghar Soltanieh told reporters. We welcome this event, we are fully cooperating. IAEA Director-General Mohamed ElBaradei announced the draft agreement after two and a half days of tense talks involving Iran, France, Russia and the US in Vienna. But the talks failed to finalise the deal as the IAEA and three powers had pushed for. Iran has engaged in time-buying manoeuvres in the past to blunt UN demands for curbs on its secretive nuclear programme. I have circulated a draft agreement that in my judgment reflects a balanced approach to how to move forward," he said. The deadline for the parties to give, I hope, an affirmation action is Friday, ElBaradei told reporters. I cross my fingers that by Friday (tomorrow) we have an OK by all the parties concerned, he said, betraying widespread uncertainty over whether Iran would make a concrete commitment. But ElBaradei did not reveal whether Iran had finally agreed to that key point after three days of talks in Vienna. The draft plan would reduce the high risk cited by the West of Iran, under suspicion over nuclear secrecy and restrictions on UN inspections, covertly refining LEU to the high level of purity suitable for nuclear weapons. This is a proposal that suits France and all our partners. Now we have to wait and see if Iran will accept it. They have two days to let us know if it suits them, said Jacques Audibert, the French Foreign Ministrys political director. The plan was to remove this (uranium) from Iran, use it to make the fuel they need and thereby improve relations and lower the tensions over Irans civilian nuclear program, he said on France 24 television. Under the deal, Russia would further refine Irans 5-per cent-enriched uranium to 19.7pc and France would process it into fuel rods to power the Tehran reactor. Everybody is aware (this) transaction is a very important confidence-building measure that can defuse a crisis going on for a number of years, and open space for (further) negotiations on other outstanding disputes, ElBaradei said. The top French nuclear negotiator said his country backed the draft agreement tabled by the UNs atomic watchdog on the supply of enriched uranium to Tehran. Jacques Audibert said the deal would require Tehran to ship out 1,200 kilograms of its stockpiled uranium by year end for enrichment in Russia, then France - a key sticking point in negotiations.
