Abstract

JAERI has developed 50kA current leads for the International Thermonuclear Experimental Reactor (ITER). The Center Solenoid (CS) Model Coil program is under way by means of international collaboration in ITER-EDA. The CS model coil is being developed for ITER CS coil and is for demonstration for ITER construction. The performance test of the CS model coil will be carried out at the JAERI ITER common test facility (CTF). The current lead consists of the vertical lead and the connection lead. The vertical lead is a vapor-cooled type and has a cable-in-conduit geometry. The vertical lead was designed with a heat leak of 1.2W/kA at a helium flow rate of 0.06g/(s·kA). The measured heat leak satisfied the designed value. The connection lead was made from copper pipe soldered with NbTi supreconducting wires. The pipe was stabilized by the supreconducting wires and a cooling channel. The current lead was operated up to 60kA. The design and the performance test results of 50kA current leads are reported. The results meet the specifications for the CS model coil test and for the ITER real machine.
