Abstract: In order to limit as much as possible the number of thermal shocks in the spallation target and the
reactor core, ADS-class accelerators require an extremely high reliability of less then 5 beam-trips per year. The
recent European (FP5) Study PDS-XADS has established the following to be the main parameters for reliable
accelerator operation: use of derated and redundant components, intrinsic fault tolerance and a dedicated
maintenance strategy. In this paper the progress of certain aspects of reliability studies done at the Institute of
Nuclear Physics in Orsay will be presented. The low level RF fast feedback system for the SC cavities operation,
providing the necessary beam stability, will be discussed. Also the conceptional design of the RF power coupler
that requires a high level of robustness is given.
