There is an urgent need for artificial intelligence technology in nuclear engineering. The Artificial Intelligence Group of HAECO's stacker team combined the research work carried out in the areas of radiation field inversion and reconstruction, intelligent control and operation procedure optimization, numerical model construction, data-mechanism hybrid modeling, intelligent operation and maintenance (prediction, anomaly detection), knowledge graph construction of the system, and research on nuclear power intelligence, and carried out a The latest research results are reported, and the latest software products are also displayed, with a view to providing reference and support for the application of intelligent technology in the field of nuclear power.
