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.

一个集成的核心和外围等离子体的代码已经开发，使代码能够研究剖面的形成和崩溃的多输运障碍（TB）。利用所开发的程序进行了模拟，阐明了边缘TB塌缩的排热特性、通过燃料芯块的注入触发边缘TB塌缩的机制、在保持高等离子体压力的情况下减少排热的条件以及边缘TB塌缩对根据电流分布形成的盒形内部TB的影响较小。对抛物线型内结核的输运模型进行了验证。
