Role of the pedestal structure in ELMy H-mode plasmas for the core energy confinement and for the ELM energy losses have been investigated in JT-60U and ASDEX Upgrade. The confinement degradation seen at higher densities is attributed to the reduction of the pedestal temperature limited by the ELM activities and the stiffness of the temperature profiles. In high triangularity or impurity seeded H-modes, in which higher energy confinement is generally achieved, higher pedestal temperature is obtained by the improvement of the edge MHD stability or the density profile peaking, respectively. The upper bound of the ELM energy loss is characterised by the pedestal energy. The energy transport in between ELMs enhanced with increasing the pedestal collisionality reduces the ELM loss power fraction. It is also shown in ASDEX Upgrade that the continuous pellet injection is valid for the integrated performance of smaller ELM losses and favourable core confinement.

Times Cited Count:32 Percentile:68.43(Physics, Fluids & Plasmas)A simplified mass ablation and relocation treatment of high field side/low field side pellet injection is proposed. It includes a model of pellet ablation, parallel flow model for the attached ablation channel and a simplified magnetohydrodynamic (MHD) pellet displacement model. This treatment reveals satisfactory agreement with the present day experiments on ASDEX-U and DIII-D tokamaks. The model provides the optimisation directions for deep plasma fuelling in experiments. Calculation with ITER parameters suggests that deep penetration up to ~ 60-70% of minor radius is possible at modest velocity <0.5 km/s with high field side injection.
