TEHRAN – Russia signed a preliminary agreement to build at least two more nuclear power plants in the Iranian port city of Bushehr, Iran's official IRNA news agency reported yesterday. The deal was reached during a visit to Tehran on Tuesday by a senior official of Russia's state atomic energy agency Rosatom, IRNA said. "Iran and Russia reached a preliminary agreement to build at least two new nuclear power plants," Iranian Atomic Energy Organization spokesman Behrouz Kamalvandi told the news agency. The two new plants will be constructed alongside the existing power station in Bushehr, which was also built by Russia, Kamalvandi said. In January, Iranian President Hassan Rouhani told his Russian counterpart Vladimir Putin that establishing long-term relations between the two countries "can serve the stability and security of the region."
