Russia is studying an Iranian proposal to build more reactors at the Bushehr nuclear power plant, the head of Russia\'s state-controlled nuclear corporation, Rosatom, said on Thursday. \"We are currently studying the proposal, as the international community has no concerns about the construction of nuclear power generation units,\" Rosatom head Sergei Kiriyenko said. The project, if approved, would require amendments to an intergovernmental agreement between Russia and Iran, he said.
