Development of advanced man-machine system for nuclear power plants

By using recent knowledge information processing technology as the technical base, the project subsidized by Ministry of International Trade and Industry 'Development of man-machine system for nuclear power plants' has been advanced. The objective of this project is to support the knowledge-based action of operators which arises in the various aspects of operation and maintenance of nuclear power plants. In this case, it becomes important to construct the system which has the various functions of inference and judgement and to realize an intelligent man-machine interface conforming to the recognizing process of operators. In this paper, the state of development so far is reported centering around the configuration and the main functions of the system. In the operation management of nuclear power plants, the development of various operation support systems has been carried out. However, in order to increase further the safety and reliability of plants, this project is advanced. The contents of the development, the normal operation support system, the operation support system at the time of abnormality and accident, the maintenance support system and the intelligent man-machine interface are described.
