The APR-1400 (for Advanced Power Reactor 1400 [MWe]) 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.
