The novel cooling method of central solenoid (CS) was studied to extend the inner space and to shorten the total height of CS for JT-60SA. The cooling pipes and insulation breaks become 0 and 50% of initial design, respectively. The height becomes 2.3 m shorter. The thermo hydraulic analysis showed the sufficient temperature margin 1K. The superconductor manufacturing factory was constructed at Naka site of JAEA in 2008. The manufacturing of CS conductors was started in 2011. One 238 m and six 466 m conductors were produced.
