Iran's first nuclear power station has begun operating at full capacity, a Russian firm said on Friday.
"The reactor of unit 1 of the Bushehr nuclear power plant was brought up to 100 percent of its projected capacity at 18:47 local time on August 30," Russian contractor Atomstroiexport said in a press release.
Construction of Bushehr began in the 1970s but has been dogged by delays. Russia signed a billion-dollar deal with Tehran to complete the plant in1998.
The plant's launch in August 2010 prompted Israel and other nations to express fears the reactor could help Iran creat an atomic bomb.
Tehran has denied the allegations, saying the facility was for peaceful power generation only.
The plant was connected to Iran's electricity grid in September 2011.
