The Korea Hydro & Nuclear Power Co. (KHNP) returned a nuclear reactor back to operations after it received its license extension.
The 678-MW Wolsong 1 unit had been offline since November 2012 when the license expired. The Nuclear Safety and Security Commission issued a license extension in February.
The Korea Institute of Nuclear Safety completed inspections and stress tests on the reactor in October and concluded that it can be operated until November 2022. The unit has undergone 100 days of comprehensive maintenance and additional inspections to ensure that it meets revised safety requirements following the 2011 Fukushima accident.
South Korea has 23 reactors in operation providing about 30 percent of the country’s electricity supply.
