Iran's nuclear point man says the country's first nuclear power plant will be inaugurated in the southern Iranian port city of Bushehr by September. "Today we passed one of the most important and final test, the hot water tests, of Bushehr power plant before its inauguration," IRNA quoted Head of the Atomic Energy Organization of Iran Ali Akbar Salehi as saying on Wednesday. "After 37 years, grounds have been prepared for the plant's opening," he further explained. "We have reached the point of no return. Grounds are prepared for the final opening of the reactor," he stressed. The construction of the plant started in 1975 when Germany signed a contract with Iran. Berlin, however, pulled out of the project following the 1979 Islamic Revolution.
