Various advances in the high-fidelity integrated modelling platforms used throughout Europe (JINTRAC, ETS and ASTRA) were discussed to support the development of ITER's high-fidelity plasma simulator (HFPS), which is also currently based on JINTRAC (core-edge-SOL-divertor/wall transport and source modelling) in combination with DINA (free-boundary plasma equilibrium evolution). Topics covered the modelling platforms, current ramp-up modelling for validation, tungsten impurity transport modelling and prediction, and further improvements of core transport and pedestal/scrap-off-layer models. Fast-pulse design and optimization tools, including the ITER pulse design simulator (PDS), were also presented to share their status and plans.
During a tour of the ITER Assembly Hall. Advanced predictive modelling of plasma operation scenarios will be required in ITER and future tokamaks not only to prepare their research plans with detailed experimental campaigns, but also to support the design and validation of tokamak components and controls, and to analyze plasma discharges obtained during experimentation.
