| Research Abstract |
An integrated code for core and peripheral plasmas has been developed so that the code enables the study of profile formation and collapse of multi transport barriers (TB). Simulations with the developed code clarify that heat exhaust characteristics of edge TB collapse, mechanism to trigger the edge TB collapse by the injection of fuel pellet, conditions to reduce the heat exhaust with keeping the high plasma pressure, and low impact of edge TB collapse on the box-type internal TB formed depending on the current profile. The validation of transport models for the parabolic-type internal TB also has been done.
