This publication presents the proceedings of a NEA workshop, held in May 2002 in the US, to discuss RandD activities regarding the use of high power proton accelerators in nuclear energy systems. Issues discussed include: the reliability of the accelerator and the impact of beam interruptions on the design and performance of accelerator-driven systems; spallation target design characteristics and their impact on the subcritical system design; safety and operational characteristics of a subcritical system driven by a spallation source; and test facilities.

These proceedings of the Second Workshop on Utilisation and Reliability of High Power Proton Accelerators placed special emphasis on accelerator-driven system (ADS) concepts comprising a sub-critical reactor coupled with a high power accelerator.

The use of high power particle accelerators in various areas of applied nuclear science is presented with special emphasis on accelerator driven reactor systems (ADS) for transmutation of nuclear waste.

This publication contains the technical papers presented at a NEA workshop, held in the Republic of Korea in May 2004, to consider research into the use of accelerator-driven systems (ADS) in radioactive waste management, as well as summaries of the working group discussions. Topics discussed include: accelerator reliability; target, window and coolant technology; sub-critical system design and ADS simulations; safety and control of ADS; ADS experiments and test facilities.
