Abstract

The Japan Atomic Energy Research Institute has a collaboration with the European Union, the United States of America and the Russian Federation for the International Thermonuclear Experimental Reactor (ITER). In the engineering design activity for ITER, a test coil named QUench Experiments on Long Length (QUELL), using 91 m and 1/5-size ITER superconducting conductor, was fabricated by JAERI. The performance tests were carried out at the SULTAN facility in Switzerland where quench propagation, thermal and hydraulic characteristics were determined and development and test of new quench detection system were conducted. The thermal and hydraulic behavior was not known well. This conductor has a central channel to reduce the pressure drop. In order to investigate the thermal and hydraulic characteristic of the conductor, the pressure drop has been measured at 5–13 K and 2–11 g/s, and the friction factor of the central channel was calculated. In heat slug propagation, an inductive and resistive heater on the conductor has been used and the velocity of the heat front and input energy are estimated from the temperature change of conductor.
