A sensitivity analysis of numerical predictions for beryllium erosion and migration in ITER

Nuclear Materials and Energy, 2021
The present study addresses the uncertainties that affect the recently performed predictions of beryllium (Be) erosion and migration in ITER using the Monte-Carlo code ERO2.0. The focus of the study is a D–T baseline discharge with fusion power gain Q=10,

Global tungsten erosion and migration modeling for the EU-DEMO with the ERO2.0 code

Nuclear Fusion
Global tungsten migration, thus erosion, transport, and deposition, in the EU-DEMO tokamak is investigated using ERO2.0 simulations for an argon-seeded ELM-free H-mode plasma scenario with expected 2 GW fusion power developed with the narrow-grid version

Angular distribution dependence of W migration on the ITER divertor from ERO2.0 simulations

Nuclear Fusion
The tungsten (W) surface of the ITER divertor might provide suitable surface temperatures and helium (He) influxes for the formation of microscopic fuzz structures.

An update of Tritium co-deposition in ITER using WallDYN3D

Nuclear Materials and Energy, 2022
The retention by co-deposition of fuel species in Be-layers, forming due to migration of Be eroded from the 3D-shaped main chamber wall in ITER, was modeled with WallDYN-3D.

Model validation of tungsten erosion and redeposition properties using biased tungsten samples on DiMES

Nuclear Materials and Energy, 2023
An experiment was performed in the DIII-D lower divertor to validate numerical SOL tungsten (W) impurity erosion and redeposition simulations against experimental data. The net and gross erosion of W were calculated as a function of the voltage (or bias)

First 3D modelling of tungsten erosion and migration in WEST discharges adopting a toroidally non-symmetric wall geometry

Nuclear Materials and Energy, 2023
Numerical analysis is a useful tool to investigate tungsten (W) sources and transport across plasma in W Environment Steady state Tokamak (WEST) plasma discharges, as it highlights physical mechanisms not always directly observable in experiments ...

Laser ablation molecular isotopic spectroscopy: A novel tool to characterise the distribution of 13C and 12C on graphite after 13CH4 tracer injection in Wendelstein 7-X

Nuclear Materials and Energy, 2022
Wendelstein 7-X (W7-X) operation with inertially cooled graphite Test Divertor Unit (TDU) was finalised in a series of identical hydrogen plasmas with injection of 13C isotopically marked methane. The break-up of 13CH4, injected through gas inlets at one
