The purpose of this paper is to explain the lessons learned during modernization of Kori-1 and Korean standard nuclear power plants. Kori-1 main control room was partially modified in 2007 and will be renovated entirely in 2013. Digital devices have been introduced and standard alone computer systems have been integrated into the plant computer. The initial scope and period of modernization have changed due to configuration and economical constraints. Upgrading KSNP I&C is planned for 2015. However, the site engineers and operators are reluctant to the advanced systems. A prototype is being developed to evaluate user interfaces and I&C architecture, and increase the acceptance level of the operators and field engineers. The 1st layer displays are based on a simplified P&ID, and the 2nd and 3rd layers are edited for additional information. The layers are linked through a context sensitive menu. The end point view of MCR is also suggested considering reliability and operability of the digital systems. Finally, modernization strategies over the overhaul periods, that do not have much impact on operation and configuration efforts are suggested. The 1st and 2nd stages are scheduled for non-safety and safety I&C upgrade, respectively. The final stage is devoted to MCR upgrade.
