The Kori Nuclear Power Plant is a South Korean nuclear power plant located in Gori, a suburban village in Busan. It is owned and operated by KEPCO. The first reactor began commercial operation in 1978.

An expansion of the Kori Nuclear Power 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. Two further APR-1400 reactors are in planning.
