I and C functional test facility with ASICS and ADIOS

Recently, digital technology is introduced to instrumentation and control systems in nuclear power plants. It is actively proceeded in the nuclear industry that the intelligent technologies apply to operation and operator support system. In this paper, The Automatic Startup Intelligent Control System (ASICS) that automatically controls the PWR plant from cold shutdown to 5 percent of reactor power and Alarm and Diagnosis-Integrated Operator Support System (ADIOS) that is integrated with alarms, process values, and diagnostic information to an expert system focused on alarm processing are described. The performance and the function of ASICS and ADIOS are evaluated with the real-time functional test facility and the results are shown that the developed systems are efficient and useful for operation and operator support (author) (ml)
