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

Autor: D.P. Coster

Publikováno v: Nuclear Materials and Energy, Vol 12, Iss , Pp 1055-1060 (2017)

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

Strongly radiating and detached high-power discharges in present-day full-metal tokamaks have a characteristic radiation pattern involving condensation of radiation near the X-point, with significant radiative losses above the X-point. In contrast, D
