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…
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…
The MEMENTO code for modelling of macroscopic melt motion in fusion devices
K. Paschalidis, F. Lucco Castello, S. Ratynskaia +2
The MEMENTO (MEtallic Melt Evolution in Next-step TOkamaks) code is a new numerical implementation of the physics model originally developed for the MEMOS-U code with the objective…
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…
