MOSCOW, Sept. 7 (UPI) -- Russian sources say the Bushehr nuclear power plant, which Russia is building in Iran, will not be ready until fall 2008. "It will be possible to install the entire complex of equipment at the Bushehr (nuclear power plant) no earlier than autumn 2008," a Russian nuclear expert told Itar-Tass. "The delay is caused by the unsettled problems of financing of the construction work by the Iranian customer. These problems emerged in March and remain unsettled to this day."Russia's Federal Agency for Nuclear Power said Thursday no strict deadlines had been set for the commissioning of the plant, RIA Novosti reported Friday. "Part of the equipment intended for the Bushehr construction has not been delivered, and final assembly of the NPP, according to most optimistic forecasts, will be completed no earlier than the fall of 2008," a Russian source said.
