The South Korean Nuclear reactor Kori-4 has been shut down

The fourth reactor of the Kori South Korean nuclear power plant (NPP) near Busan (South Korea) has been stopped on March 28 due to the rise of the level of the cooling water. No radioactive leakage has been reported. The Kori power plant is owned by Korea Hydro & Nuclear Power Co. Ltd. (KHNP), a subsidiary of Korea Electric Power Corp. (KEPCO).



The Kori NPP and the neighbouring Shin Kori NPP are composed of the following units:

- Kori-1, which will be stopped in June 2017, and Kori-2 with a capacity of 600 MW each

- The Kori-3 (900 MW) and Kori-4 (950 MW) reactors have been commissioned in 1985 and 1986

- The Shin Kori-1 and Shin Kori-2, two operational OPR-1000 reactors (950 MW net, 1,000 MW gross) that have been commissioned in 2011 and 2012, respectively

- The Shin Kori-3 is the first Korean-designed Advanced Pressurized Reactor-1400 (APR-1400, rated 1,340 MW net) to start up



A second APR-1,400 reactor (1,350 MW net, 1,400 MW gross), Shin Kori-4, is under construction on the site and is expected to start up in the first half of 2017.
