One critical issue in steady-state and high-performance operation in future tokamak fusion
reactors is to develop H-mode operational regimes that mitigate or eliminate the large …

The new numerical implementation of the MEMOS-U physics model, fully validated in
multiple EUROfusion sponsored experiments, is presented. The computational tool …

An analysis workflow has been developed to assess energy deposition and material
damage for ITER vertical displacement events (VDEs) and major disruptions (MD). This …

Reliable modeling of macroscopic melt motion induced by fast transients requires the
accurate and computationally efficient description of the emitted current density that escapes …

The beryllium (Be) main chamber wall interaction during a 5 MA/1.8 T upward, unmitigated
VDE scenario, first analysed in [J. Coburn et al., Phys. Scr. T171 (2020) 014076] for ITER …

Fusion is considered to be the green and ultimate source of energy for the future. There are
many engineering and physics restrictions in achieving this goal. One major problem is high …

We develop a 0D model of vapor shielding including a vast variety of processes in the vapor
cloud and plasma-surface interactions. The model is applied to a liquid lithium (Li) divertor …

Recent studies demonstrate that when a plasma-facing surface emits a sufficient flux of
electrons, it will form an inverse sheath. Here, we consider a possibility of using thermionic …

The production and dynamics of beryllium melt pools are simulated in conditions relevant to
unmitigated thermal quenches in ITER. Rayleigh–Taylor instabilities fed by Lorentz forces …

The boundary conditions (BCs) involving a plasma-wall transition (PWT) are crucial when
estimating the particle and heat fluxes at the wall, and when simulating the edge plasma …
