计划将JT-60改造为全超导托卡马克（JT-60 SC）。JT-60 SC方案的目标是为高性能等离子体的稳态运行和在经济和环境上具有吸引力的DEMO反应堆中使用低活化材料建立科学和技术基础。与演示堆相关的先进聚变技术已经为JT-60 SC设计的超导磁体技术和面向等离子体的部件开发出来。为了实现超导股线的高电流密度，新开发了高铜比（4）的Nb 3Al股线，用于JT-60 SC的环向场线圈（TFC）。使用全尺寸Nb 3Al导体进行了通过反应和风力技术来证明Nb 3Al导体对TFCs的适用性的研发。研制成功了一种全尺寸低交流损耗铌钛导体，采用镀镍绞线。首次研制了一种螺旋管强冷高传热偏滤器组件。在电子束辐照试验台上成功地验证了碳纤维复合靶的排热性能。
Modification of JT-60 as a full superconducting tokamak (JT-60SC) is planned. The objectives of the JT-60SC programme are to establish scientific and technological bases for steady-state operation of high performance plasmas and utilization of reduced-activation materials in an economically and environmentally attractive DEMO reactor. Advanced fusion technologies relevant to the DEMO reactor have been developed for the superconducting magnet technology and plasma facing components of the JT-60SC design. To achieve a high current density in a superconducting strand, Nb3Al strands with a high copper ratio of 4 have been newly developed for the toroidal field coils (TFCs) of JT-60SC. The R&D to demonstrate the applicability of the Nb3Al conductor to TFCs by a react-and-wind technique has been carried out using a full-size Nb3Al conductor. A full-size NbTi conductor with low ac loss using Ni-coated strands has been successfully developed. A forced cooling divertor component with high heat transfer using screw tubes has been developed for the first time. The heat removal performance of the carbon fibre composite target was successfully demonstrated on an electron beam irradiation stand.
