The Engineering Design Activities (EDA) for the International Thermonuclear Experimental Reactor (ITER) was performed under the collaboration of Japan, EU, Russia and the US. The EDA was successfully completed in July 2001, in which the development of fabrication technology for advanced components, such as superconducting coils, was conducted. The ITER magnet system consists of Toroidal Field coils, a Central Solenoid (CS), Poloidal Field coils and Correction coils. The construction of these coils requires advanced technologies that fairly exceeded those available at the start of the EDA. Therefore, CS Model Coil and TF Model Coil projects were implemented. To fabricate the CS Model Coil, the fabrication technologies for high performance strand, large cable, winding, heat treatment, joint and insulation are indispensable. This report describes the above detailed fabrication technologies successfully developed in the CS Model Coil Project.

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.
