Integrated modeling activities for ITER scenarios in JAEA

Honda, Mitsuru; Hayashi, Nobuhiko

We will report the status of the integrated modeling activities in JAEA and latest simulation results in ITER by using an integrated code TOPICS-IB. For integrated modelings, we have integrated a neutral transport code with TOPICS-IB so as to study the energy loss and the cycle of ELMs with density dynamics. By using TASK/TX with OFMC and EPOC, we have reproduced the toroidal rotation due to the radial current induced by the charge separation in a plasma with NBI and clarified its physical mechanism. We briefly explain the present status of the integrated divertor code SONIC. For steady-state simulations in ITER, we confirmed the validity of the integration of TOPICS-IB with an LH code, comparing the simulation result with that by ACCOME. Furthermore, we compared the neoclassical heat diffusivity by the Matrix Inversion Code with that by NCLASS because a performance of an ITER plasma in a steady state is found to depend on it.
