The pulse extension up to 30 s has been done on JT-60U Positive ion-based NBI (P-NBI) system to study the high beta plasma for long pulse duration. The pulse of Negative ion-based NBI (N-NBI) has also been extended up to 25 s. Now, to contribute to ITER and DEMO, modification of JT-60U to a superconducting device (so called JT-60SA) has been planned by both parties of Japan and EU. The NBI system of JT-60SA is required to inject 34 MW for 100 s by using twelve P-NBI units (24 MW) and one N-NBI unit (10 MW). The engineering design has been progressed on the base of the long pulse operation of 30 s. Present statue of JT-60 NBI system and upgrade plan for JT-60SA will be presented.

JT-60SA is positioned as the satellite tokamak of ITER to perform the ITER-relevant research through the optimisation of the operation scenario, as well as the steady-state high-beta plasma research oriented to DEMO. The design of the poloidal field magnet is optimised to realise the same aspect ratio and plasma shape as those in ITER. For the extension of operational regime towards high performance plasma, heating power is increased to 41 MW with 100 s. The prospect of plasma performance, analysed by equilibrium code and by transport code, indicates the high density and high plasma current sustainability with the ITER similar shape due to the increases in the electron temperature, beam driven current and bootstrap current.
