      abstract     = {SOLPS-ITER modelling databases of three
                      tokamaks—ASDEX-Upgrade, JET and ITER with fluid drifts
                      activated are compared to understand the dependence of edge
                      plasma performance on machine size and other global
                      parameters. Two medium Z extrinsic radiating impurity
                      species (Ne and N) are considered. It is demonstrated that N
                      is better kept in the divertor region than Ne in
                      semi-detached and detached divertor conditions due to
                      smaller first ionization potential (FIP effect). Together
                      with the fact that Ne radiates more efficiently at higher
                      plasma temperatures, this leads to an increase in the
                      efficiency of Ne for divertor heat load control with
                      increasing machine size. In larger machines such as JET and
                      ITER Ne can be as efficient a radiator as N while for
                      ASDEX-Upgrade Ne easily leads to radiation from the pedestal
                      and loss of H-mode stability. The relative roles of various
                      physical effects are compared for the three tokamaks based
                      on both whole databases and in more details for chosen
                      semi-detached regimes with comparable fraction of radiated
                      power. It is shown that for smaller machines drift effects
                      are more significant and divertor asymmetries more
                      pronounced.},
