SOLPS-ITER drift modelling of ITER burning plasmas with narrow near-SOL heat flux channels

Nuclear Materials and Energy, 2021
SOLPS-ITER code simulations with fluid drifts activated are used to examine the consequences for divertor performance, under burning plasma conditions, of a reduction in scrape-off layer (SOL) cross-field transport such that the outboard midplane SOL ...

SOLPS-ITER modeling of ASDEX Upgrade L-mode detachment states [PDF]

, 2021
SOLPS-ITER is used to model ASDEX Upgrade L-mode detachment states including the onset of detachment, the fluctuating detachment, and the complete detachment states, considering drifts and mimicking filamentary convective transport with a radial outward ...

First Monte‐Carlo modelling of global beryllium migration in ITER using ERO2.0

Contributions to Plasma Physics, Volume 60, Issue 5-6, June-July 2020., 2020
Abstract ERO2.0 is a recently developed Monte‐Carlo code for modelling global erosion and redeposition in fusion devices. We report here on the code's application to ITER for studying the erosion of the beryllium (Be) first wall armour under burning plasma steady state diverted conditions.

Exploring the edge operating space of fusion reactors using reduced physics models

Nuclear Materials and Energy, 2017
Reduced physics models within SOLPS have been used to explore the edge operating space of fusion reactors by building a database of simulations for various input powers and various combinations of impurity puffing.

SOLPS-ITER analysis of a proposed STEP double null geometry: impact of the degree of disconnection on power-sharing

Nuclear Fusion, 2023
To mitigate the issue of plasma exhaust in reactor scale tight aspect ratio tokamaks such as Spherical Tokamak for Energy Production (STEP), a double-null (DN) configuration is thought to be advantageous over a single-null (SN) configuration.

SOLPS-ITER Study of neutral leakage and drift effects on the alcator C-Mod divertor plasma

Nuclear Materials and Energy, 2017
As part of an effort to validate the edge plasma model in the SOLPS-ITER code suite under ITER-relevant divertor plasma and neutral conditions, we report on progress in the modeling of the Alcator C-Mod divertor plasma with the new code.

SOLPS-ITER validation with TCV L-mode discharges editors-pick [PDF]

, 2021
This work presents a quantitative test of SOLPS-ITER simulations against tokamak a configuration variable (TCV) L-mode experiments. These simulations account for drifts, currents, kinetic neutrals, and carbon impurities providing the most complete edge ...

Comparison of divertor seed impurity gases retention efficiency by SOLPS-ITER modeling

Nuclear Fusion
In the paper a SOLPS-ITER modeling of H-Mode scenarios with different seed impurity gases (N, Ne, Ar, Kr) is performed for ASDEX Upgrade geometry. These gases are compared from the point of view of their radiation efficiency and compression in the ...

Stabilization of EMC3-EIRENE for detachment conditions and comparison to SOLPS-ITER

Nuclear Materials and Energy, 2019
Numerical access to cold divertor conditions in tokamaks with EMC3-EIRENE has been proven to be challenging, but is now possible for the first time after a linearization of the electron energy sink term from interaction with neutral gas.
