Artificial Intelligence in Reactor Physics: Current Status and Future Prospects
It addresses the need for better AI integration in nuclear reactor operations and safety, but is incremental as it synthesizes existing research rather than introducing new breakthroughs.
This paper reviews the application of artificial intelligence, particularly machine learning, in reactor physics to improve efficiency in simulations, safety, and core management, noting that most methods enhance deterministic approaches or correct uncertainties to meet industry demands.
Reactor physics is the study of neutron properties, focusing on using models to examine the interactions between neutrons and materials in nuclear reactors. Artificial intelligence (AI) has made significant contributions to reactor physics, e.g., in operational simulations, safety design, real-time monitoring, core management and maintenance. This paper presents a comprehensive review of AI approaches in reactor physics, especially considering the category of Machine Learning (ML), with the aim of describing the application scenarios, frontier topics, unsolved challenges and future research directions. From equation solving and state parameter prediction to nuclear industry applications, this paper provides a step-by-step overview of ML methods applied to steady-state, transient and combustion problems. Most literature works achieve industry-demanded models by enhancing the efficiency of deterministic methods or correcting uncertainty methods, which leads to successful applications. However, research on ML methods in reactor physics is somewhat fragmented, and the ability to generalize models needs to be strengthened. Progress is still possible, especially in addressing theoretical challenges and enhancing industrial applications such as building surrogate models and digital twins.
