South Korea has 16 nuclear reactors in operation, producing 15,252 megawatts of power, or about 79 percent of total capacity, according to data compiled by Bloomberg. Two additional plants are undergoing trials with 1,837 megawatts of capacity online.

The following table shows the status of the nation’s 21 reactors with a combined regular capacity of 19,259 megawatts and an additional two that are in pilot operations by state-run Korea Hydro & Nuclear Power Co. as of today.
