abstract = {The integrated model JINTRAC is employed to assess the
dynamic density evolution of the ITER baseline scenario when
fuelled by discrete pellets. The consequences on the core
confinement properties, α-particle heating due to fusion
and the effect on the ITER divertor operation, taking into
account the material limitations on the target heat loads,
are discussed within the integrated model. Using the model
one can observe that stable but cyclical operational regimes
can be achieved for a pellet-fuelled ITER ELMy H-mode
scenario with Q = 10 maintaining partially
detached conditions in the divertor. It is shown that the
level of divertor detachment is inversely correlated with
the core plasma density due to α-particle heating, and thus
depends on the density evolution cycle imposed by pellet
ablations. The power crossing the separatrix to be
dissipated depends on the enhancement of the transport in
the pedestal region being linked with the pressure gradient
evolution after pellet injection. The fuelling efficacy of
the deposited pellet material is strongly dependent on the
E × B plasmoid drift. It is concluded that
integrated models like JINTRAC, if validated and supported
by realistic physics constraints, may help to establish
suitable control schemes of particle and power exhaust in
burning ITER DT-plasma scenarios.},
