Summary

The central solenoid (CS) model coil programme was performed from 1992 as one of the Engineering Design Activity (EDA) projects of the International Thermonuclear Experimental Reactor (ITER). The CS model coil programme involves a plan to develop the toroidal field (TF) insert to demonstrate the conductor performance of ITER TF coils under a magnetic flux density of 13 T. The TF insert was fabricated by Russia and tested by Japan within the framework of the ITER-EDA. The TF insert developed a single-layer solenoid with nine turns. It is wound with a cable-in-conduit conductor which consists of 1152 Nb3Sn strands, a thin titanium jacket and a central channel. The outer diameter, height and weight of the TF insert are 1.56 m, 3.2 m and 3.1 ton, respectively. Fabrication of the TF insert was completed in May 2001 at the Efremov Institute in St. Petersburg, Russia. The TF insert was then transported to the Japan Atomic Energy Research Institute (JAERI). Installation of the TF insert to CS model coil test facility was completed in August, 2001. The TF insert was charged to 13 T with 46 kA without any instability under a back up magnetic field from the CS model coil. This report introduces an overview of the fabrication, installation and experiments for the TF insert conducted thanks to the collaboration between Japan and Russia.
