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.
