Exploring the edge operating space of fusion reactors using reduced physics models

Abstract

Reduced physics models within SOLPS have been used to explore the edge operating space of fusion reactors by building a database of simulations for various input powers and various combinations of impurity puffing. A robust operating window is found for ITER power levels in the ITER sized machine simulated — the window shrinks dramatically at the higher powers explored, though a few operating points are found.
