Abstract
Accurate prediction of fusion performance in present and future tokamaks requires taking
into account the strong interplay between core transport, pedestal structure, current profile and
plasma equilibrium. An integrated modeling workflow capable of calculating the steady-state self-
consistent solution to this strongly-coupled problem has been developed. The workflow leverages
state-of-the-art components for collisional and turbulent core transport, equilibrium and pedestal
stability. Validation against DIII-D discharges shows that the workflow is capable of robustly pre-
dicting the kinetic profiles (electron and ion temperature and electron density) from the axis to the
separatrix in good agreement with the experiments. An example application is presented, showing
self-consistent optimization for the fusion performance of the 15 MA D-T ITER baseline scenario
as functions of the pedestal density and ion effective charge Z eff.
