KHNP placed an order worth $1.2 billion for components of Shin-Kori 3 and 4 with Doosan Heavy Industries in August 2006. Doosan then contracted $300 million of this work to Westinghouse. In all, the units are expected to cost $5 billion. A consortium led by Hyundai will actually construct the power units. The overall cost of the project is $6.3 billion over seven years.
In the south-east of the country, nearby Kori was South Korea's first nuclear power plant. Its four Westinghouse PWRs started up between 1978 and 1986.
Shin-Kori 1 and 2 are already half-constructed. Their OPR-1000 design is an evolution of the Kori units' design; the APR-1400 technology for Shin-Kori 3 and 4 represents a further evolution in power output, operation and safety. Its construction and power generation costs are reported to be 10% lower than those of OPR-1000 units.
South Korea has 20 nuclear power reactors, all owned and operated by Korea Hydro and Nuclear Power (KHNP). Together they provide about 40% of the country's electricity. By 2014 there should be 26 nuclear power reactors in operation, maintaining about the same proportion of supply.
In addition to this project, Shin-Wolsong 1 and 2 are currently under construction. They are OPR-1000 reactors, 35% complete.
