Transient events such as disruptions, plasma startup, and pellet fueling play a critical role in determining design requirements for the tokamak reactor. This has led to an increasing demand for integrated modeling tools capable of analyzing and optimizing these processes within reasonable computational resources. This talk presents an overview of our group’s activities conducted in close alignment with Japanese experimental and reactor-design programs such as LHD, JT-60SA, and JA-DEMO. Several topics will be introduced, covering both physical modeling, such as pellet ablation, and computational aspects, including equilibrium-transport coupling implemented in the INDEX code. The talk will also touch upon experimental validation efforts carried out ASDEX Upgrade, and other tokamak devices, in collaboration with the ITER Disruption Mitigation System (DMS) task force.
