Utilisation and Reliability of High Power Proton Accelerators

Workshop Proceedings, Daejeon, Republic of Korea, 16-19 May 2004

image of Utilisation and Reliability of High Power Proton Accelerators

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.



Status of the Spallation Neutron Source Accelerator Complex

Nuclear Energy Agency

The Spallation Neutron Source accelerator system will provide a 1-GeV, 1.44-MW proton beam to a liquid mercury target for neutron production. The accelerator complex consists of an H– injector capable of producing a 38-mA peak current, a 1-GeV linear accelerator, an accumulator ring and associated transport lines. The linear accelerator consists of a drift-tube linac, a coupled-cavity linac and a superconducting linac which provide a 1.5-mA average current to the accumulator ring. The design of the accelerator systems is complete; installation of the accelerator components is in progress; and staged beam commissioning is proceeding as installation progresses. The installation and final commissioning of the project is on schedule for completion in early 2006. The status of the project design, installation and commissioning will be presented.
