Upgrading I&C and computer systems at KORI 1

摘要

The KORI nuclear power plant unit 1 had analog modules for process protection and control and PRODAC-2500 for plant monitoring based on 1960s and 1970s technology. After 20 years of operation, a successful I&C upgrade project was completed. The project was initiated due to growing concerns of obsolescence, increased maintenance costs and overall ageing of equipment.
