Kori Nuclear Power Plant (Korean: 고리원자력발전소) is located in Kori Village, Busan City, east of South Korea. Close to the Sea of Japan. The installed capacity is 7,489 MW.
It is owned and operated by Korea Hydro & Nuclear Power, a subsidiary of KEPCO. The Kori Nuclear Power Plant currently has 8 reactors; there are 6 reactors in operation, of which 1 is still under construction and 1 has been decommissioned (but will remain in In the complex until the materials can be safely stored and removed).
Units 2, 3, and 4 started commercial operations in the 1980s, and are all slated to be decommissioned in the mid-2020s. All reactors on site are pressurized water reactors.
The nuclear power plant plans to build two more reactors. However, following a speech by President Moon Jae-in in June 2017 after announcing the phase-out of nuclear power projects in South Korea, construction was suspended.
Reactors
An expansion of the plant begun in 2006 added 4 new Korean-sourced reactors, the so-called Shin Kori reactors (shin meaning “new”). The first pair of Shin Kori reactors are of the OPR-1000 design, while the second two are the APR-1400 design.
Shin Kori 1 & 2 achieved commercial operations in 2011 and 2012 respectively, with Shin Kori 3 & 4 achieving commercial operations in 2016 and 2019. Construction on two further APR-1400 reactors, known as Shin Kori-5 and Shin Kori-6, was started in April 2017 and September 2018, respectively.
In November 2019, the reactor pressure vessel of the 1340MWe APR-1400 reactor to be housed in Shin Kori 5 was installed. As of November 2019, construction on the Shin Kori 5 and 6 was 51 percent complete.
Kori Nuclear Power Plant is currently the largest nuclear power plant in operation in the world. Because of a serious accident at the Kashiwazaki-Kariwa Nuclear Power Plant in Japan in 2011, it has not restarted until 2020.
