Magnetic fusion reactors need a superconducting coil system with the huge magnetic energy of approximately 100 GJ. A number of superconducting fusion experimental devices have been constructed since 1970. Accumulated technologies and experiences for the past 35 years now allow us to design the actual reactors. However, there still remain some engineering problems in order to design the commercial reactors that will need a low construction cost, a high field and high reliability. It is necessary to develop high-strength supporting materials, next-generation superconductors and high-current-capacity conductors.
