Possible work on JT-60 SA scenarios Association Euratom-CEA • Simulations of JT-60 SA scenarios should be based on the two machines that are the most similar, for size and configuration: JT-60 U and JET • First steps: Ø Ø Ø Ø define reference JT-60 U and JET shots (H-mode, hybrid, advanced) give access to databases (or create a common database) these shots should be mainly based on NBI H&CD establish a simulation data exchange method define transport, pedestal, rotation models benchmark actuator computations (should be OK due to ITPA work, but…) run predictive simulations for the reference shots • Try to find a unified modelling framework that works for both machines: this should give the maximum confidence for prediction of JT-60 SA • fast parameter range exploration with METIS (0. 5 code) • Run predictive simulations fo JT-60 SA with both JA and EU codes • For the predicted scenarios, perform linear MHD analysis; for the most interesting cases, try non-linear MHD analysis Meeting ISM, Cadarache G.
