Abstract

Effective for real-time fault diagnosis of nuclear power plants, improve equipment reliability, in the traditional paper based on the introduction of expert system fault tree analysis, design based on a comprehensive diagnosis of the important degree of reasoning mechanism and the introduction of the mechanism model diagnostics expert system for diagnosis validation, and further improve the diagnostic reliability of the system. In order to diagnose faults of nuclear power plants effectively, and to improve reliability of plants, fault tree analysis technique was introduced to traditional expert system in this article, ratiocinative mechanism based on synthetical diagnosis importance was designed, and mechanism model diagnosis technique was introduced to validate the result of expert system. Therefore, the reliability of diagnosis system was improved ulteriorly
