III.9 — Accelerator driven systems

Accelerator Driven Systems (ADS) are considered as devices for the transmutation of long-lived nuclear waste. This chapter aims at giving an overview of the nuclear waste management issues and the accelerator requirements for successful ADS operation, in particular the stringent beam availability requirement. It then highlights the most significant activities worldwide in this domain. Common features are: high-power superconducting proton linacs and reliability-oriented R\&D.
