Considerations on the DEMO pellet fuelling system

•Considerations are made for a core particle fuelling system covering all DEMO requirements.•Particle deposition beyond the pedestal top is needed to achieve efficient fuelling.•Conventional pellet technology enabling launching from the torus inboard side can be used.•Efforts have been taken for integrating a suitable pellet guiding system into the EU DEMO model.•In addition, further techniques bearing potential for advanced fuelling performance are considered.
