Centralized Data Processing System/ Safety Panel System (KIT/KPS)

KIT/KPS are important I&C systems in nuclear power plants, mainly performing data acquisition and centralized data processing functions. They are the vital supervising means in CI, NI and BOP to monitor normal operation, system maintenance, accident conditions and post accident conditions. They can provide operators and other staffs with information on normal operation, accident diagnosis, and post-accident analysis and perform functions such as acquisition and processing of site on/off and analogue data,, alarm handling and display monitor, log record, historical data management, report print and etc.

KPS includes display of a series of functions, logic formulas and calculation, analog diagram, forms and other information as well as function of human-machine dialogue operation. Every function is indispensable and constitutes a safety shield for nuclear power plants.
