Summary of the theory and modelling contributions at the 30th IAEA Fusion Energy Conference (FEC 2025)
The contributions in magnetic fusion theory presented at the 30th IAEA Fusion Energy Conference (FEC 2025) are summarized. This summary provides information on novel ideas and briefly reviews the most recent advances along the main avenues of the research, such as plasma integrated modelling, computational physics and application of artificial intelligence, fast ion instabilities, runaway electrons, disruptions, pellets, and some others. Given the current interest in bringing the magnetic fusion to the burning plasma state, the focus of the theory was on burning plasma physics.
