Model (DT plasmas)
L-mode ITER 5,10,15MA/5.3 T and ECRH
H-mode ITER 5,7.5,10,15 MA/5.3 T and 7.5MA/2.65T with ECRH, NBI (+Pa)
Increased gas puff-rate up to detachment
Full integrated modelling with JINTRAC for core/SOL heat/particle transport
Results
Density below NBI shine-through limit in L-mode phase for all currents except 15MA with gas-fuelling only
15MA/5.3T stationary H-mode phase sustainable with gas-fuelling only and Q~7-8  this performance can be achieved because of high nsep before detachment, anomalous core density peaking (low n*) and high Tped Q
