MOSCOW -- The launch of a Russian-built nuclear power plant in Iran could be delayed because Iran has fallen behind in payments, Russian officials said yesterday . Top Iranian officials swiftly denied that payments had been disrupted, in the latest dispute surrounding the deal at the heart of the two countries' nuclear cooperation.
Last year, Russia agreed to ship nuclear fuel to Bushehr -- Iran's first nuclear plant -- by March 2007 and launch the facility in September, with electricity generation to start by November. Under a separate deal, Iran agreed to return to Russia all spent fuel from the plant in southern Iran for reprocessing -- a move intended to assuage global concerns that the fuel could be diverted to make nuclear weapons. Iran broke the schedule of payments this year under the $1 billion contract, said a Russian official, who asked not be named because he was not authorized to speak to the media. He said the Iranians blamed the delay on the need to switch payments from dollars to euros.
