摘要

The International Atomic Energy Agency has sponsored a Co-ordinated Research Programme (CRP) which explored the application of expert systems technology for use by the nuclear industry in matters related to safety. The various projects submitted in the CRP addressed hazard identification, emergency operating procedures, modelling nuclear power plant (NPP) behaviour during transients, verification and validation as well as diagnosis, human factors and probabilistic safety analysis (PSA). This final report summarizes four years of collective effort and addresses key issues and examples concerning the development of safety related expert systems. The extensive use of PSA for nuclear installations led to the accumulation of a large amount of information relevant to safety. Expert systems techniques were examined as effective ways to apply the information for improvement of NPP safety and reliability. A number of approaches were envisaged by considering a wide variety of issues including the needs of NPP personnel, costs vs. benefits, potential user acceptance, and verification and validation problems. These issues were identified as keys to the development of viable safety related expert systems and are discussed in the main body of the report. A number of examples of the development of prototype expert systems are described and the issues affecting the development of NPP safety related applications are highlighted. Refs, figs and tabs.
