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…
3D modelling of thermal loads during unmitigated vertical displacement events in ITER and JET
F. J. Artola, A. Redl, S. N. Gerasimov +9
Predicting three-dimensional thermal loads during tokamak disruptions is essential for ITER yet remains weakly developed. We present a physics-based workflow that couples MHD simul…
Thermal resilience of the ITER tungsten first wall to runaway electron impact
S. Ratynskaia, K. Paschalidis, T. Rizzi +7
The fast volumetric deposition of multi-MeV high current runaway electron (RE) beams constitutes the most critical issue for the ITER tungsten (W) first wall (FW) longevity. Such r…
Impact of repetitive ELM transients on ITER divertor tungsten monoblock top surfaces
K. Paschalidis, S. Ratynskaia, P. Tolias +1
Owing to the high stored energy of ITER plasmas, the heat pulses due to uncontrolled Type I edge localized modes (ELMs) can be sufficient to melt the top surface of several poloida…
