South Korean power utility Korea Hydro and Nuclear Power (KHNP) has commissioned its new Shin Kori-4 nuclear reactor, the fourth unit of the Shin Kori nuclear power plant. With a lifetime of 60 years, the Advanced Pressurized Reactor-1400 (APR1400) reactor, rated 1,400 MW, is expected to generate 10.4 TWh/year of electricity.
Located near the southeastern city of Busan, the Shin Kori nuclear power plant consists of the Shin Kori-1 and Shin Kori-2, two operational OPR-1000 reactors (950 MW net, 1,000 MW gross) that were commissioned in 2011 and 2012, respectively, and of the 1,340 MW Shin Kori-3 unit, the first Korean-designed APR-1400, which was commissioned in December 2016. The construction of Shin Kori-4 started in August 2009 and was delayed, as for Shin Kori-3, by technical issues. Shin Kori 4 was initially expected to be commissioned in November 2017.
South Korea currently operate a total of 25 nuclear reactors at home, which provide roughly a third of its total electricity needs.
