We simulate the heat conduction, sputtering, evaporation, excitation and radiation of lithium and tin in the divertor area. Measured high-resolution data from COMPASS tokamak were rescaled towards the Upgrade based on many established scalings. Our simulation then yields the amount of released metal which ranges from 4 mg s−1 upto 12 g s−1 depending mainly on the geometry and Li/Sn choice, quite independently from active cooling or strike point sweeping.
