| 概要 |
The burning performances on improved modes are examined by the transport analysis with fuel dilution. The crucial problems to sustain an ignited plasma, such as the confinement physics of fast apartic...le, typical studies on the He-ash contamination, the thermal instability are firstly reviewed. Including the effects of dilution due to He-ash and the energy loss due to radiation, the ignition condition is shown. The analysis is applied to the ITER-grade tokamak. Based on the zero-dimensional transport model, the thermal stability of ignited state on the L-mode, the high ,Bp-mode and the ELMy-H mode are examined. The burning performances on these modes are compared. Taking the presently argued operational limits ( e.g., the density limit) into account, the characteristics of the core plasma are discussed. The transport model is extended to one-dimensional transport model. The existence of the ignition condition and the accessibility to it are evaluated. It is shown that the internal transport barrier is formed autonomously even if parameters lie in the L-mode boundary condition. The profile effect on the burning performance is also studied. Introducing Kadomtsev type reconnection model for MHD instability, long time sustainment of burning is examined.続きを見る
