FIREWALL: A surrogate model for the rapid assessment of tokamak wall loading and melting by runaway electrons
Victor Johan Svensson, Tommaso Rizzi, Svetlana Ratynskaia +4
Runaway electron (RE) beams generated during tokamak disruptions can deposit highly localized heat loads on plasma-facing components, posing a serious risk of melting and damage. M…
Runaway electron induced explosions of graphite; modeling versus controlled DIII-D experiments
T. Rizzi, A. Kavroulakis, S. Ratynskaia +10
The state-of-the-art concerning the modeling of the thermomechanical response of graphite to runaway electron (RE) impact is based on one-way coupled linear thermoelasticity combin…
Thermal modeling of runaway electron induced damage in the SPARC tokamak
T. Rizzi, K. Paschalidis, S. Ratynskaia +6
The integrity of plasma-facing components (PFCs) in tokamaks is critically challenged by transient events such as runaway electron (RE) impacts. We report the first systematic anal…
Runaway electron-induced plasma facing component damage in tokamaks
S. Ratynskaia, M. Hoelzl, E. Nardon +31
This Roadmap article addresses the critical and multifaceted challenge of plasma-facing component (PFC) damage caused by runaway electrons (REs) in tokamaks, a phenomenon that pose…
