Nowadays, more and more technologies of AI including machine learning and deep learning are being developed. Using AI, we can automate recognition, prediction and implementation of something. Although introducing these technologies to the nuclear industry is difficult, it can be the best solution to solve problems we are facing such as plant efficiency and labor shortage. In the US and some European countries, they have already put AI into practice in the field of nuclear power plant maintenance as the automation of tasks of condition reports, the anomaly detection of components, making digital manuals and chatbot etc. In addition, some advanced researches, for example, monitoring fire, a hybrid AI and computational mechanics approach for the life estimation of components, quantifying the uncertainty and planning of actions during accidents, are being done. Finally, a Federal Register was published in April 2021 about NRC gathering information on the nuclear industry’s state of developing and introducing AI.
