Fusion is the energy source of the sun. The fuel for fusion reactors, deuterium and lithium, is extractable from seawater, which is abundant and available worldwide. An enormous amount of energy can be generated from a small amount of fuel. Fusion reactors are relatively safe (runaway reactions cannot occur) and have low environmental impact (no carbon emission, short-lived radioactivity). Therefore, fusion reactors are expected to be long-term clean alternative energy sources.
Sub-issue D focuses on the development of simulation technologies that will lead towards practical fusion reactors. We will contribute to determining optimized operation scenarios in the next generation experimental fusion reactor ITER by performing five-dimensional (5D) first-principles simulations on the post-K computer.

Target

Optimize operation scenarios for fusion reactors by 5D first-principles simulations of burning plasmas

Challenges

5D first-principles simulations (based on the Boltzmann’s equation) of plasma turbulence and magnetohydrodynamics (MHD) phenomena in ITER core plasmas are extremely challenging, but will be made possible using the post-K computer. We will develop simulation methods and physics models for analysis of burning plasma in ITER, and establish standard core design codes, to lead the ITER project forward.
