      abstract     = {A numerical study is presented, using the SOLPS-ITER plasma
                      boundary code with full drifts and currents activated, of
                      impurity seeded JET discharges in support of high power
                      H-mode experimental campaigns designed to compare two ITER
                      candidate seeding species, nitrogen (N) and neon (Ne).
                      Fluid-kinetic edge plasma simulations are first performed at
                      lower levels of power into the scrape-off layer (SOL) and
                      benchmarked against existing JET experimental data.
                      Calculations are then performed for higher levels of SOL
                      power to examine the impact of this key parameter on the
                      efficiency of both radiators. From the code point of view,
                      for the chosen JET parameters, Ne can be as efficient a
                      divertor radiator as N at the same level of upstream
                      separatrix Zeff < 1.5 for moderate seeding, decreasing the
                      peak power at outer target by factor ~ 3. Full detachment
                      (state with the temperature below 5 eV along all the target)
                      at the outer target can be obtained with both impurities at
                      higher seeding, but in the case of Ne this leads to a higher
                      Zeff and significant radiation in the main SOL/pedestal. The
                      indications from this JET code modelling, in comparison with
                      previous similar simulations for ITER and ASDEX Upgrade with
                      drifts turned on, are that there is a beneficial impact of
                      machine size in improving impurity retention, substantiating
                      the claim that both N and Ne will perform well as seed
                      impurities for divertor power dissipation in ITER.},
