Research plan and current status of fusion plasma code development

Idomura, Yasuhiro   

The research plan and the current status of fusion plasma code development in the Post-K priority issue 6 "Development of Innovative Clean Energy" [Core Design of Fusion Reactor] are reviewed. This project develops first principles based plasma analysis codes on plasma turbulence phenomena and MHD phenomena, which are taken into account in the design of operation scenarios of fusion reactors. Because of the spatio-temporal scales in ITER core plasmas and the complexity of their physics models including multi-species ions and burning processes, these fusion plasma analysis codes require new simulation techniques. In this talk, we discuss the development of Exa-scale computating technologies such as many-core optimization, and new physics and numerical models to enable long time scale simulations.
