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.

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 ...

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 ...

Erosion and deposition in the JET divertor during the second ILW campaign

, 2017
Erosion of plasma-facing materials and successive transport and redeposition of eroded material are crucial processes determining the lifetime of plasma-facing components and the trapped tritium inventory in redeposited material layers.

Tungsten coatings under high thermal loads in JET and Magnum-PSI [PDF]

, 2014
During the C28–C30 campaigns the ITER-like wall (ILW) was periodically inspected by an in vessel inspection system without breaking the vacuum. After these campaigns the JET chamber was opened and the wall was inspected with a high resolution camera. The

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 ...
