Predictive Modelling of L-H Transition in ITER 15MA Q = 10 Plasma

A fully self-consistent predictive simulation of the typical ITER 15 MA scenario with Q = 10, which is based on the type-I ELMy H-mode discharge, is performed for the flat top part of the scenario starting from the end of current ramp-up phase using the GLF23 and Bohm/gyroBohm transport model implemented in JINTRAC1. This work has a purpose to investigate the characteristic time delay between ITER plasma entering the H-mode after onset of full heating and reaching the burning conditions with Q = 10. Therefore, the sensitivity parametric scans are carried out with the variation of pellet fuelling rate (Gpellet, dne/dt), inward particle pinch (V) and particle diffusivity (D).
