Description
The coupled dynamics of the radial profiles (magnetic and kinetic) in a tokamak
are described by a set of non-linear partial differential equations. RAPTOR is a
control-oriented core transport code, solving these equations based on empirical
or first-principle-based models for the heat transport. The present work presents
the extension of RAPTOR to allow rapid calculation of consistent stationary
solutions, either imposing all actuator inputs, or the plasma loop voltage. The
fast stationary state solver is embedded in a numerical optimization algorithm,
yielding a valuable tool for optimization of the flat-top phase of tokamak dis-
charges. Formulating different parameter optimization problems, this tool can
rapidly explore advanced tokamak scenarios, optimizing confinement and exter-
nal power requirements.
