The 1,340-MW (net) APR-1400 plant, near the southeastern city of Busan, can operate for 60 years and will generate about 12% of the electricity used in the country’s southeastern cities, the Korea Hydro and Nuclear Company said in a statement.
Shin-Kori-4 is the second South Korea-designed APR 1400 model to begin supplying electricity to the grid. The first was Shin-Kori-3, which began commercial operation in December 2016.
The APR-1400 plant is the same model under construction at the Barakah nuclear station in the United Arab Emirates.
According to the International Atomic Energy Agency South Korea has 25 nuclear units in commercia operation and four under construction.
