In the Japan Atomic Energy Research Institute (JAERI), the concept of the transmutation of minor actinides (MA: Np, Am and Cm) with accelerator-driven systems (ADS) is being studied, where MA nitride is adopted as a fuel material of sub-critical core. The nitride fuel has been chosen as a candidate because of the possible mutual solubility among the actinide mononitrides and excellent thermal properties besides supporting hard neutron spectrum. Highly enriched N-15 would have to be used for the nitride fuel in order to prevent the formation of hazardous C-14. By applying pyrochemical process in the treatment of spent fuel, N-15 could be readily recovered and recycled. The present paper describes an overview of the research on the nitride fuel performed in JAERI. Fabrication experiments of actinide nitrides, measurements of vaporization behavior and thermal properties, and irradiation tests of actinide nitrides are summarized.

A design study of the accelerator-driven system (ADS) for transmutation of minor actinides and long-lived fission products has been performed at Japan Atomic Energy Research Institute (JAERI) under the national OMEGA program. To solve the technical issues related to the ADS development, a transmutation experimental facility (TEF) is planned to bulid under the JAERI-High Energy Accelerator Research Organization joint project. The TEF consists of two facilities, Transmutation Physics Experimental Facility and Transmutation Engineering Experimental Facility. Proton beams of 600 MeV and 0.3 mA are to be delivered to this facility. The presentation describes a conceptual design study of the TEF.
