Pedestal prediction with Europed code in JT-60SA

Controlled thermonuclear fusion is a highly capable source of clean energy in the future. To achieve
commercial controlled fusion with magnetic confinement device an important step is the utilization
of the high-confinement mode and associated phenomenon including pedestal structure and edgelocalized
mode instabilities. To study high confinement mode and associated phenomenons
simulation is combined with experiments. This thesis performs pedestal stability simulation with
the Europed simulation code for the Japan Torus-60 Super Advanced (JT-60SA) tokamak for both
ideal magnetohydrodynamics equations and resistive magnetohydrodynamics equations. It is found
that increasing pedestal top density and density profile relative shift shows de-stabilizing effect
to the pedestal, whereas increasing normalized plasma beta stabilizes the pedestal. A combined
parameter scan reveals that these three parameter’s effect on the pedestal has no correlation with
each other. Under resistive magnetohydrodynamics simulations it is found that including resistivity
is a generally de-stabilizing effect. This work provides an overview of high confinement mode
operation for the future experiments in JT-60SA and serves as a staring point for more in-depth
study of the effect of resistivity.
