[1N07] A fast discharge scheme of toroidal field coils for a fusion demo reactor
Keywords:fusion demo reactor, toroidal field coil, fast discharge, insulation voltage, inductance
An inductance of toroidal field (TF) magnet in a fusion demo reactor is 3-4 times greater than that of ITER. The higher value of the inductance increases a turn insulation voltage generated in emergency fast discharge processes. We propose a fast discharge scheme of TF coils for avoiding the voltage increase with electrically dividing the magnet into two systems.
