Scenario development of ITER ELMy H-mode hydrogen plasma

Here we study the possibility for ITER ELMy H-mode operation in hydrogen plasma at 7.5MA/2.65T using up to 33MW NBI and 20 -- 30MW ECH, intended for commissioning of the ELM control systems. Two strategies are considered to lower $P_\textrm{L--H}$: a) operation at low density, or b) introducing $\sim$10\% He (since this is observed to decrease $P_\textrm{L--H}$ in JET~[1]). The scenarios are modelled self-consistently using JINTRAC~[2], developed by EUROfusion for integrated core (JETTO/SANCO/EDWM), edge and SOL/divertor modelling (EDGE2D/EIRENE). Results obtained so far indicate that stationary ELMy H-mode is indeed accessible, with and without 10\% He, provided that the ECH power level is 30MW. [1] D.C.
