| Outline of Final Research Achievements |
Multi-species turbulent transport of fuel and impurity ions in fusion burning plasmas is explored by means of the first-principle-based five-dimensional gyrokinetic simulations. Towards the burning plasma, which is composed of several kinds of ions, a multi-species simulation model including inter-species collisions is developed, where the verification and validation studies for the prediction capability of the simulation code are carried out. The turbulence simulation studies with the extended multi-species model made a significant research progress through the clarifications of the hydrogen isotope mass dependence of the microinstabilities, and of the transport properties of fuel ions and helium-ash in burning plasma turbulence.
