Expert System Interfaced ASSA Module for Fault Diagnosis for Instrumentation of Accident Conditions

To keep the system safety, we have to increase two important parameters. The first parameter is the reliability of both system safety and system operators. The second is the availability of safety systems. The improvement of system reliability is the subject in this content. One of the major factors in reliability improvement needs a diagnosis system for the quick action item. This is offered by developing an export system that helps the operator to deduce the failed component in the control and safety system in case of emergency. Meanwhile, it also aids in an action the failed component immediately since the operator has already recognized it. Thus, using this export system, the reliability of both the operator and the system will be increased. This paper uses an new expert system interfaced ASSA (abnormal signal simulation analysis) module for fault diagnosis of an instrumentation control systems. The ASSA module was developed by KAERI Lab lately. Therefore, our expert system could obtain enhanced signal patterns from the abnormal signals using an ASSA function instead of an old expert system
