Reactor 1 of the Uljin nuclear power plant, in Korea (south), was restarted on 28 August 2012.
Less than a week prior the reactor automatically shut itself down. After investigating, the Korea Hydro & Nuclear Power Company said the emergency shut down was due to a glitch in electrical lines running to the reactor.
It was the second time in August that a Korean nuclear reactor went through emergency shut down.
Korea (south) currently has 23 nuclear reactors in operation, and is building more. They hope to have 39 by the Gregorian/Western/Christian calender year 2030.
