After decades of delay and sanctions, Iran will launch on Saturday its Russian-built first nuclear power plant. Iran's nuclear chief Ali Akbar Salehi said that on Saturday the Russia-supplied fuel will be transferred inside the building in which the engine of the Bushehr power station in southern Iran is located.Salehi said the fuel transfer would be completed by September 5 and two weeks later the reactor would reach 50 per cent of its power-generating capacity, allowing it to be linked to the national grid. He said it will take six to seven months to reach the maximum power level of the plant. The much-anticipated launch of the more than one-billion-dollar Bushehr plant comes despite Moscow hardening its position on Iran's nuclear programme by backing a fourth round of UN sanctions against Tehran on June 9.
