 note = {JT-60SA is a highly shaped large superconducting Tokamak device. The project mission of JT-60SA is to contribute to early realization of fusion energy by supporting the exploitation of ITER and by complementing ITER in resolving key physics and engineering issues for DEMO with a variety of plasma actuators (heating, current drive, momentum input, stability control coils, resonant magnetic perturbation coils, W-shaped divertor, fuelling, pumping, etc) .
   Fabrication and installation of components and systems of JT-60SA procured by EU and Japan are steadily progressing towards start of operation in 2020. Up to April 2017, seven TF coils have been arrived at Naka from EU (ENEA in Italy, and CEA in France) after completing the careful cold test and preassembly with the outer inter-coil structure at CEA Saclay. The 340-gegree part of the Vacuum Vessel (VV) and the thermal shield surrounding VV has been welded accurately, and the four TF coils have been installed around VV (Fig.1). Manufacture of all the six EF coils have been completed by QST with excellent accuracy of manufacture. Commissioning of the cryogenic system from EU was also completed in the Naka site. Sixteen High Temperature Superconducting current leads (in total 26) has been deliverd from Germany (KIT). Commissioning of the power supply system (ENEA, RFX, CEA and QST) has also been implemented smoothly. Manufacture of the Cryostat Vessel Body is also reaching its final phase in Spain (CIEMAT).
   The JT-60SA Research Plan (SARP) ver. 3.3 was issued in March 2016 by 378 co-authors (JA 160 (16 institutes), EU 213 (14 countries, 30 institutes) and the STP-PT (5). The main revision point of ver. 3.3 is the update of EU-DEMOs and JA-DEMO parameters. The revision made it clear that JT-60SA covers wide research areas for DEMO, both pulsed and steady-state operations. The fifth JT-60SA Research Coordination Meeting (RCM) was held at QST Naka in May 2016. Contribution of JT-60SA to ITER was emphasized in relation to the expected delay of ITER. The physics R&D priorities in JT-60SA fulfilling ITER needs were suggested by the ITER Organization and discussed by all of the participants. Critical issues, such as disruption mitigation, L-H threshold power, ELM mitigation, diagnostic R&D, should be tested in JT-60SA. It became a consensus of the JT-60SA research unit to modify the basic strategy of the Integrated Research Phase II (~2030) of JT-60SA so as to start with full coverage of Tungsten divertor and Tungsten first wall and accompany the initial heating experiments of ITER., 27th IEEE Symposium on Fusion Engineering},
