| Outline of Final Research Achievements |
An integrated code for core and peripheral plasmas has been developed so that the code enables the study of fueling, impurity exhaust and mitigation of edge profile collapse. In the study, an interface model to couple fluid code with Monte-Calro particle code has been also developed. Simulations with the developed code clarified that optimum conditions for pellet injection to mitigate the edge profile collapse, the compatibility between the mitigation control and fueling, and the realization of high-pressure steady-state operation scenario by the evaluation of impurity accumulation and its effect on core plasma performance.
