Conceptual design of SC magnet system for ITER, (3). AC loss

Technical Report:

Abstract

The International Thermonuclear Experimental Reactor (ITER) is an experimental thermonuclear tokamak reactor testing the basic physics performance and technologies. The joint work of the conceptual design activity of ITER was carried out at the Max Planck Institute for Plasma Physics in Garching Germany from 1988 to 1990. The Japanese proposals for the superconducting (SC) coil system were summarized by the Fusion Experimental Reactor (FER) Team and the Superconducting Magnet Laboratory of the Japan Atomic Energy Research Institute (JAERI). This report is one of the series reports of `conceptual design of SC magnet system for ITER`, and treats the AC losses of the superconducting coil. The AC loss means the heat production in the winding packs and the supporting structure due to magnetic field change. Since the AC losses occupy about 50% of the total heat loads during the normal operation, the estimation of AC loss is important. On the other hand, the estimation of the AC loss during the disruption is also required to consider the stability of the superconducting coil. From these reasons, AC losses in the TF and PF coil winding packs and the supporting structures were computed for the normal operation and for the disruption. In addition  More>>
