“…Since the model is relatively complex, and has been already presented elsewhere [5,6] we will concentrate here only on the most important aspects of the model. In the core, the 1D radial transport equations for bulk ions, for each ionization state of impurity ions and for the electron and ion temperature are solved.…”

In this paper we present results of numerical simulations of nitrogen seeded JET discharges. In particular, we have benchmarked the code against the type III ELMy JET pulses. In addition to recovering the main discharge parameters, the interplay between seeded nitrogen and intrinsic carbon is also reproduced. Predictions for the JET discharges with higher plasma current Ip = 3.5 MA and different input powers (14 < Paux < 23 MW) demonstrate that it is possible to achieve high radiation fractions (> 80%) and simultaneously reduce both the plasma collisionality and Z ef f . Extrapolation to ITER shows compatibility of strongly radiative plasmas with the power amplification in excess of 10.

“…The several Demo design concepts [1] have been analyzed [2] using the code Corediv. The code Corediv [3,4] solves self consistently the core and scrape off layer regions. The numerical analyses [2] show that there exists the limit on the concentration of impurities above which the solution with burning plasma does not exists.…”

The several Demo design concepts have been analyzed using the code Corediv solving self consistently the core and scrape off layer regions. The numerical analyses show that there exists the limit on the concentration of impurities above which the solution with burning plasma does not exists. This limits reduce the possibility of reduction of power loads to target plate. In the paper the admissible range of seeded impurity concentration introduced to reduce the power load to divertor plate is analyzed. The possible mechanisms leading to the limitation are shown.
