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.



Corrosion Tests in the Static Condition and Installation of Corrosion Loop at KAERI for Lead-Bismuth Eutectic

Nuclear Energy Agency

Lead-bismuth eutectic (LBE) corrosion has been considered as an important design factor to limit the temperature and velocity of the accelerator-driven transmutation system. For the corrosion study, KAERI finished the set-up of the LBE static corrosion facility and also finished the preliminary design of a dynamic corrosion loop and started a set-up process to construct the loop by the fall of 2004. In this paper, we describe the results of the preliminary static test during 500 hrs under a reduced condition to check the performance of the static facility. We also describe a design concept of corrosion loop and the state of the art for its installation at KAERI, as well as the results of EM pump preliminary testing.
