N2 - In this work, the SOLPS-ITER code package was applied to predict the plasma conditions in the alternative divertor configurations in the future upper divertor in AUG. The transport coefficients, boundary conditions and gas puffing rates in the simulations are selected to reproduce the experimentally measured profiles in dedicated upper single null H-mode discharges in AUG. Using the same input parameters, the plasma conditions in the single null case were then extrapolated to those in the snowflake divertor and the X-divertor configurations. The simulation showed much lower target power fluxes and a detached divertor in these alternative divertor configurations while the divertor in the single null reference is still attached. The alternative divertor configurations thus show an advantage in solving the power exhaust problem.
