      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.},
