Predictive JET current ramp-up modelling using QuaLiKiz-neural-network [PDF]

open access: yesNuclear Fusion, 2023
This work applies the coupled JINTRAC and QuaLiKiz-neural-network (QLKNN) model on the ohmic current ramp-up phase of a JET D discharge. The chosen scenario exhibits a hollow $T_\mathrm{e}$ profile attributed to core impurity accumulation, which is ...

Simulations of the stationary Q = 10 and the exit phase from the flat-top of an ITER 15MA baseline scenario: predictive JINTRAC simulation with a consistent treatment of D and T in the whole plasma

open access: yesNuclear Fusion
Designing a robust termination scenario for a burning ITER plasma is a challenge that requires extensive core plasma and divertor modelling. The presented work consists of coupled core/edge/SOL/divertor simulations, performed with the JINTRAC code, to ...

Access and sustainment of ELMy H-mode operation for ITER pre-fusion power operation plasmas using JINTRAC

open access: yesNuclear Fusion
In the initial stages of ITER operation, ELM mitigation systems need to be commissioned. This requires controlled flat-top operation in type-I ELMy H-mode regimes.

ELM and inter-ELM tungsten erosion sources in high-power, JET ITER-like wall H-mode plasmas

open access: yesNuclear Materials and Energy, 2022
Simulations of JET ITER-like wall high-confinement mode plasmas, including type-I edge-localised modes (ELMs), using JINTRAC for the background plasmas and ERO2.0 for tungsten erosion and transport, predict virtually perfect screening of the primary W ...

JINTRAC: A System of Codes for Integrated Simulation of Tokamak Scenarios

open access: yesPlasma and Fusion Research, 2014
Operation and exploitation of present and future Tokamak reactors require advanced scenario modeling in order to optimize engineering parameters in the design phase as well as physics performance during the exploitation phase. The simulation of Tokamak scenarios involves simultaneous modeling of different regions of the reactor, characterized by ...

Effect of PFC Recycling Conditions on JET Pedestal Density [PDF]

open access: yesContributions To Plasma Physics, 2016
There is experimental evidence that the pedestal dynamics in type-I ELMy H-mode discharges is significantly affected by a change in the recycling conditions at the tungsten plasma-facing components (W-PFCs) after an ELM event.

Self-consistent simulation of plasma scenarios for ITER using a combination of 1.5D transport codes and free-boundary equilibrium codes

open access: yesNuclear Fusion, 2013
Self-consistent transport simulation of ITER scenarios is a very important tool for the exploration of the operational space and for scenario optimisation.

Validation of EDGE2D-EIRENE and DIVIMP for W SOL transport in JET

open access: yesNuclear Materials and Energy, 2020
Tungsten sputtering rates and density profiles predicted using the edge plasma codes EDGE2D-EIRENE and DIVIMP are found to agree within a factor of 4 with measurements of neutral and singly-ionized W spectral line emission in the JET low-field side (LFS)

Global JINTRAC Simulations for ITER PFPO Scenario Development [PDF]

open access: yesNuclear Fusion, 2021
The inductive goal of ITER is to produce 500s long burning plasmas with Q = Pfus/Paux >=10[1]. This requires the development of operationally robust scenarios that span the whole plasma discharge from startup to termination not only in Deuterium Tritium (DT) but also in the Pre Fusion-Plasma Operation (PFPO) phase in Hydrogen (H) and Helium (He).

Assessment of the ITER divertor bolometer diagnostic performance

open access: yesNuclear Materials and Energy, 2023
The ITER bolometer diagnostic will provide measurements of the total radiation emitted from the plasma, a part of the overall energy balance. It will consist of some 550 lines of sight (LOS) of bolometer detector, bundled in multiple individual cameras ...
