Construction now is under way on both the Shin Kori Units 3 and 4 nuclear powerplants. These units will be the first of a new generation of light-water reactors called Advanced Power Reactors in South Korea that use a domestic design developed by Korea Power Engineering Co. Both reactors will be 1,400 MW. The oceanfront site in Gori is located about 30 km north of Busan in southeastern South Korea. Excavation work began in January 2008, the first concrete for Shin Kori Unit 3 was poured in October 2008 and work on the reactor containment building currently is under way.
