Since 1990, KPS has been methodically implementing its long-term technical development plan to secure 71 key technologies for utilization in domestic and overseas projects. The company has developed Korean models of nuclear reactor primary layers, gas turbines, and other technologies that resulted in an imported technology substitution value of KRW 45.7 billion in 2006 and 2007 and KRW 47.9 billion in 2008.
