Understanding of physical processes of particle, momentum, and thermal transports is essential for predicting the confinement performance of burning plasmas in ITER, which is targeting the scientific demonstration of magnetic confinement fusion. First principles based simulations on Fugaku disclosed physical mechanisms such as complex transport processes of multi-scale turbulence in deuterium-tritium plasmas and kinetic effects in energetic particle transport due to electromagnetic fluctuations. We promote further research and development of first principles based simulations towards the performance prediction of burning plasmas.

Particle control is important for control of burning plasma, because the plasma density is one of a few controllable parameters in the burning plasma which has a self-sustained system. Heat and particle balance was studied using Slim CS parameters, where tritium is fueled in the main plasma, and deuterium is fueled in both the main plasma and the edge plasma. When the confinement times for the particles fueled in the main and edge plasmas are assumed to be 2 s and 2 ms, respectively, and the divertor pumping fraction is assumed to be 3%, the total deuterium fueling rate is one order of magnitude larger than the tritium fueling rate. Although impurity is accumulated with a peaked density profile, accumulation level is acceptable for Ar. Effect of pellet injection and gas-jet on plasma confinement is discussed and it is suggested that burning plasma control taking account of plasma confinement and a pressure profile is necessary based on the burn simulation experiments.
