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.

Concept of Transmutation Experimental Facility

Nuclear Energy Agency

Under the framework of the High-intensity Proton Accelerator Project called J-PARC (Japan Proton Accelerator Research Complex), the Japan Atomic Energy Research Institute (JAERI) plans to construct the Transmutation Experimental Facility (TEF). The TEF consists of two facilities: the Transmutation Physics Experimental Facility (TEF-P) and the ADS Target Test Facility (TEF-T). The TEF-P is a critical facility that can accept a 600 MeV, 10 W proton beam. The TEF-T is a material irradiation facility using a 600 MeV, 200 kW proton beam and a Pb-Bi target; however, neutron multiplication by nuclear fuel will not be attempted. This report describes the purpose of the facility, the present status of the conceptual design and the expected experiments to be performed.
