| 内容記述 | The integrated modelling code TOPICS has been extended to include the core impurity transport, and applied to predictive modelling of JT-60SA high-beta steady-state plasma with the accumulation of impurity seeded to reduce the divertor heat load. In the modelling, models and conditions are selected for a conservative prediction, which considers a lower bound of plasma performance with the maximum accumulation of impurity. The conservative prediction shows the compatibility of impurity seeding with the core plasma with high-beta (βN > 3.5) and full current drive conditions, i.e., when the Ar seeding reduces the divertor heat load below 10 MW/m2, its accumulation in the core is so moderate that the core plasma performance can be recovered by additional heating within the machine capability to compensate the Ar radiation. Due to the strong dependence of accumulation on the pedestal density gradient, the high separatrix density is important for the low accumulation as well as the low divertor heat load. The conservative prediction also shows that JT-60SA has enough capability to explore the divertor heat load control by impurity seeding in high-beta steady-state plasmas. | |||||
