Conference Article: Hybrid system concepts for nuclear waste transmutation

Abstract

The Japan Atomic Energy Research Institute (JAERI) is carrying out research on partitioning and transmutation under the national long-term R&D program, called the OMEGA program. The program aims at development of the technology to improve efficiency and safety in the final disposal of radioactive waste. Conceptual design studies are being made on hybrid systems driven by intense proton linacs as promising options for dedicated transmutation devices. The system bums minor actinides efficiently in a hard neutron spectrum and high neutron flux. A 30 - 60 MW experimental integrated system and a 7 MW high-power target facility are proposed to construct under a plan of an accelerator-based multi-purpose research complex called the Neutron Science Project. The experiments will demonstrate the technical feasibility of the hybrid system and the capability of minor actinide transmutation.
