Current status of sub-project D "Core design of fusion reactor"

Idomura, Yasuhiro   

In this talk, we review the current status of the sub-project D "Core design of fusion reactor" in the Priority Issue on Post-K computer (Accelerated Development of Innovative Clean Energy Systems). In the project, an interdisciplinary research team consisting of experts on applied mathematics, computer science, plasma theory, and plasma experiment has addressed (1) development of exascale computing technologies, (2) extension of physics models for burning plasmas, and (3) V&V of developed codes against large scale experiments such as JT-60 and LHD. Outcomes from the first two years of the project are presented focusing on computing techniques and physics models for analyzing multi time scale phenomena such as transient responses of plasma turbulence against auxiliary heating and intermittent bursts of energetic particles driven modes, and future issues in the latter half of the project.
