JINTRAC Coupled Core/SOL/Divertor Transport Simulations in Support of ITER*

The inductive goal of ITER is to produce 500s long burning plasmas with Q=P_fus/P_aux>=10. This requires the development of operationally robust scenarios that span the whole plasma discharge from start-up to termination. We show the value of integrated modelling to the challenge of developing scenarios that are relevant to ITER, and take a holistic approach using the core/pedestal/SOL/divertor/wall integrated modelling code JINTRAC.
The ITER Research Plan now considers its first H-modes in 5MA/1.8T Hydrogen and Helium plasmas with 20-30 MW of RF heating at <ne> ~ 0.5 n_GW. Based on our integrated modelling we will discuss features of these plasmas including: the required fuelling schemes; impurity seeding that is required to control W production and to manage divertor power loads; core transport for main ions and impurities (with emphasis on W); and the effects of discrete events like ELMs, pellets and sawteeth crashes. In parallel, JINTRAC is being ported to ITER's integrated modelling framework (IMAS) to expand its modelling capabilities, and the status of this activity will be reported.
