The development strategies on an integrated operator decision aid support (IODAS) system are discussed by focusing attention on the importance of the operator's role for nuclear power plants. The IODAS is under development to support the operator's decision making process and to enhance the safety of a nuclear power plant by providing the plant operators with timely and proper guideline during abnormal and emergency conditions. The IODAS has capabilities for the signal validation/management, the alarm processing, the failure diagnosis using abnormal operating procedures, and the dynamic tracking of emergency operating procedures using function restoration guidelines and optimal recovery guidelines with a series of complex logic steps covering a broad spectrum of event sequences. The proposed system is being implemented on a SUN-4/75 Workstation using C and Quintus[sup TM] prolog language. For verification studies a full-scope real-time simulator is being used. Test results show that the IODAS is capable of diagnosing a plant failure quickly and of providing an operator guideline with fast response time. After verification, the IODAS will be installed in the main control room of the unit one nuclear power plant at Yeoung Gwang.
