Accelerator-driven systems (ADS) are being considered for their potential use in the transmutation of radioactive waste. The performance of such hybrid nuclear systems depends to a large extent on the specification and reliability of high power accelerators, as well as the integration of the accelerator with spallation targets and sub-critical systems. At present, much R&D work is still required in order to demonstrate the desired capability of the system as a whole.
Accelerator scientists and reactor physicists from around the world gathered at an NEA workshop to discuss issues of common interest and to present the most recent achievements in their research. Discussions focused on accelerator reliability; target, window and coolant technology; sub-critical system design and ADS simulations; safety and control of ADS; and ADS experiments and test facilities. These proceedings contain the technical papers presented at the workshop as well as summaries of the working group discussions held. They will be of particular interest to scientists working on ADS development as well as on radioactive waste management issues in general.

Spoke Cavities
An Asset for the High Reliability of a Superconducting Accelerator
Nuclear Energy Agency
Taking into account the PDS-XADS requirements concerning accelerating field, quality factor and reliability, two spoke-type cavities have been designed at IPN Orsay. One of them has been successfully tested and the second one is currently being fabricated. This paper reports on the excellent performance of the first cavity, substantially exceeding the requirements, which make spoke cavities an attractive solution for a reliable PDS-XADS proton driver.
