SEOUL, April 4 (Yonhap) -- A nuclear reactor on South Korea's southeast coast was shut down Thursday afternoon due to problems installing an electricity sub-station around the nuclear power plant, plant operators said.
The Gori Nuclear Power Plant, about 450 kilometers southeast of Seoul, halted operation at around 4:34 p.m., only hours after it resumed operations following two months of maintenance that ended Wednesday.
No immediate threats of a radiation leak were detected, according to the Korea Hydro and Nuclear Power Co.
"The plant halt was caused by a wrong connection of an electricity power input line with a relay protecting the main transformer," the state-run company said.
The company said the state-run power monopoly Korea Electric Power Corp.(KEPCO) confirmed the cause and will take measures to get the power plant running.
The 950,000-kilowatt reactor began commercial operation in April 1986. The Gori Nuclear Power Plant also houses five other reactors.
