Utilisation and Reliability of High Power Proton Accelerators
Workshop Proceedings, Daejeon, Republic of Korea, 16-19 May 2004
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.

The European Project PDS-XADS “preliminary Design Studies of an Experimental Accelerator-Driven System”
Nuclear Energy Agency
During the 1990s, in different European countries, the idea of using accelerator-driven systems as efficient tools for transmutation of radioactive wastes came to the forefront. At the national level, various concepts of accelerator-driven system have also been suggested. In 1998, a Technical Working Group was mandated by the Research Ministers of France, Italy and Spain, to identify the critical technical issues and to prepare a “Roadmap” for a demonstration programme. The Roadmap, issued in April 2001, defines the main requirements of an experimental accelerator-driven system commonly accepted by the European countries. Subsequently, certain European research centres, universities and nuclear industry companies decided to merge their efforts on this topic so as to propose a common European experimental accelerator-driven system. One of the first steps towards attaining this objective is to evaluate the different candidates previously developed in Europe in order to select the most appropriate concept. This led to the creation of the Preliminary Design Studies of an EXperimental Accelerator-Driven System (PDS-XADS) project performed within the Fifth Framework Programme and supported by the European Commission.
