Abstract

A large-aspect-ratio diverted midsize tokamak KT-2 are being designed at KAERI. The KT-2 tokamak aims investigations of the advanced tokamak physics issues, thus necessitating steady-state operation capabilities with superconducting magnets. In KT-2, where normal copper magnets with active cooling are employed, this need is circumvented by incorporating long-pulse operation capabilities with minimum 4 to over 19 seconds current/field flattop. In this paper, design principles and baseline design parameters of the TF/PF magnets on the basis of KT-2 operation modes are derived and discussed. Electromagnetic and thermal analysis results are presented, with discussions of key criteria identified for the detailed engineering design which are being carried out presently
