APR-1400

The APR-1400 (for Advanced Power Reactor 1400 MW electricity) is an advanced pressurized water nuclear reactor designed by the Korea Electric Power Corporation (KEPCO). Originally known as the Korean Next Generation Reactor (KNGR), this Generation III reactor was developed from the earlier OPR-1000 design and also incorporates features from the US Combustion Engineering (C-E) System 80+ design. Currently there is one unit in operation (Shin Kori unit 3) and seven units under construction, four in the United Arab Emirates at Barakah and three in South Korea: one at Shin Kori and two at Shin Hanul. Two more units are planned with construction yet to commence at Shin Kori.

APR-1400 design began in 1992 and was awarded certification by the Korean Institute of Nuclear Safety in May 2002. The design certification application was submitted to the Nuclear Regulatory Commission in December 2014 and in March 2015, it was accepted for technical review to determine if the reactor design meets basic US safety requirements.

The first commercial APR-1400 reactors at Shin Kori were approved in September 2007, with construction starting in October 2008 (Unit 3) and August 2009 (Unit 4). Shin Kori-3 was initially scheduled to commence operation by the end of 2013, but the schedules for both Units 3 & 4 were delayed by approximately one year to replace safety-related control cabling, which had failed some tests. Construction of two more APR-1400 units at Shin Kori, Korea (Units 5 and 6) had been expected to begin in 2014, but as of December 2016 plans had not been finalised.

Construction of two new APR-1400s, Shin Hanul Units 1 & 2, began in May 2012 (Unit 1) and June 2013 (Unit 2), with Unit 1 expected to be completed in April 2017. Two more APR-1400s at Shin Hanul were approved in 2014, with construction to start in 2017.
