The Kori Nuclear Power Plant (Korean: 고리원자력발전소, Hanja: 古里原子力發電所) is a South Korean nuclear power plant located in Kori, a suburban village in Busan. It is owned and operated by Korea Hydro & Nuclear Power, a subsidiary of KEPCO. The first reactor began commercial operation in 1978.

An expansion of the plant begun in 2006 added four new Korean-sourced reactors, the so-called Shin Kori reactors. The first pair of Shin Kori reactors are of the OPR-1000 design, while the second two are the APR-1400 design. By November 2010 the first was online and the rest undergoing trials or construction. As of December 2016 approval of operation of reactor 4 is expected in the first half of 2017.[1] Two further APR-1400 reactors, known as Shin Kori 5 and Shin Kori 6, are in planning. However, the three main opposition parties for the 2017 special presidential election have pledged to stop construction on these two reactors, putting their future in doubt.[2]

Reactors

As of February 2017 all reactors on site are pressurized water reactors.

Kori 1 was shutdown in June 2017 in advance of decommissioning beginning in 2022 after its spent nuclear fuel is removed.[4]

Incidents

On 9 February 2012 at 8:30 p.m. Kori 1 was shut down for regular inspections. After this the reactor lost all power for 12 minutes, and the diesel generator did not start. The reactor was to be inspected and the nuclear fuel was to be exchanged. According to the South Korean nuclear regulator all facilities for the spent-fuel-pool and the cooling of the reactor were still operational. The incident was not reported to the regulator before 12 March 2012.[5] The incident was graded at INES level 2.[6] Subsequently five senior engineers were charged for a coverup of the serious incident.[7]

On 2 October 2012 at 8:10 a.m. Shingori 1 was shut down after a warning signal indicated a malfunction in the control rod system. An investigation is currently underway to verify the exact cause of the problem.[8]

In June 2013 Kori 2 was shutdown, and Kori 1 ordered to remain offline, until safety-related control cabling with forged safety certificates is replaced.[9] Control cabling installed in the APR-1400s under construction failed flame and other tests, so need to be replaced delaying construction by up to a year.[10]

In October 2013 cable installed in Shin Kori 3 failed safety tests, including flame tests. Replacement with U.S. manufactured cable has delayed the startup of the plant,[10][11] which eventually entered commercial operation 3 years late.[1]

Appearances

In the recently released movie Pandora, the Kori Nuclear Power Plant is a main scene in the movie. The movie touches in the dangers of nuclear energy in South Korea, and if it were to go wrong.
