초록

When abnormal operating conditions occur in nuclear power plants, operators must identify theoccurrence cause and implement the necessary mitigation measures. Accordingly, the operator mustrapidly and accurately analyze the symptom requirements of more than 200 abnormal scenarios fromthe trends of many variables to perform diagnostic tasks and implement mitigation actions rapidly. However, the probability of human error increases owing to the characteristics of the diagnostic tasksperformed by the operator. Researches regarding diagnostic tasks based on Artificial Intelligence (AI)have been conducted recently to reduce the likelihood of human errors; however, reliability issues due tothe black box characteristics of AI have been pointed out. Hence, the application of eXplainable ArtificialIntelligence (XAI), which can provide AI diagnostic evidence for operators, is considered. In conclusion,the XAI to solve the reliability problem of AI is included in the AI-based diagnostic algorithm. A reliableintelligent diagnostic assistant based on a merged diagnostic algorithm, in the form of an operatorsupport system, is developed, and includes an interface to efficiently inform operators.
