Comparison of DIVIMP and EDGE2D-EIRENE tungsten transport predictions in JET edge plasmas

Nuclear Materials and Energy, 2020
The average tungsten concentrations in the pedestal region (cW) predicted by the Monte Carlo code DIVIMP and the coupled multi-fluid plasma/kinetic neutral code EDGE2D-EIRENE are found to agree within a factor of 2 for a range of JET-ILW L-mode and H ...

Tritium distributions in castellated structures of Be limiter tiles from JET-ITER-like wall experiments

Nuclear Fusion, 2023
Tritium retention in the castellated structure of beryllium limiters used in JET with the ITER-like wall (ILW) during the first (ILW1), third (ILW3) and all three (ILW1-3) campaigns were examined and evaluated.

Main chamber wall plasma loads in JET-ITER-like wall at high radiated fraction

Nuclear Materials and Energy, 2017
Future tokamak reactors of conventional design will require high levels of exhaust power dissipation (more than 90% of the input power) if power densities at the divertor targets are to remain compatible with active cooling.

Operational challenges for long pulses on JET-ILW

Plasma Physics and Controlled Fusion
Abstract The typical pulse on the JET tokamak is ∼10 s during the main phase of the discharge, however long discharge operation (>30 s) is possible with sufficient preparation and care. During the last period of JET operation in 2023 long pulses in deuterium plasmas were developed to assess the sustainment of the plasma performance ...

Density pedestal prediction model for tokamak plasmas

Nuclear Fusion
A model for the pedestal density prediction based on neutral penetration combined with pedestal transport is presented. The model is tested against a pedestal database of JET-ILW Type I ELMy H-modes showing good agreement over a wide range of parameters ...

Progress in reducing ICRF-specific impurity release in ASDEX upgrade and JET

Nuclear Materials and Energy, 2017
Use of new 3-strap ICRF antennas with all-tungsten (W) limiters in ASDEX Upgrade results in a reduction of the W sources at the antenna limiters and of the W content in the confined plasma by at least a factor of 2 compared to the W-limiter 2-strap ...

ERO2.0 predictions of nickel migration in the JET ITER-Like Wall

Nuclear Materials and Energy
Nickel transport in the Joint European Torus with the ITER-like wall (JET-ILW) is predicted using the 3D Monte-Carlo code ERO2.0, simulating the erosion and deposition of impurities in 3D geometry and utilizing hydrogenic background plasmas generated by ...
