Abstract
The JT-60SA project has been implemented for the purpose of an early realization of fusion energy. With a powerful and versatile NBI and ECRF system, a flexible plasma-shaping capability, and various kinds of in-vessel coils to suppress MHD instabilities, JT-60SA plays an essential role in addressing the key physics and engineering issues of ITER and DEMO. It aims to achieve the long sustainment of high integrated performance plasmas under the high β N condition required in DEMO. The fabrication and installation of components and systems of JT-60SA procured by the EU and Japan are steadily progressing. The installation of toroidal field (TF) coils around the vacuum vessel started in December 2016. The commissioning of the cryogenic system and power supply system has been implemented in the Naka site, and JT-60SA will start operation in 2019. The JT-60SA research plan covers a wide area of issues in ITER and DEMO relevant operation regimes, and has been regularly updated on the basis of intensive discussion among European and Japanese researchers.

JT-60SA (super advanced) is a superconducting tokamak under construction in the Naka Fusion Institute of the National Institutes for Quantum and Radiological Science and Technology (QST). The mission of the JT-60SA project [1–4] is to contribute to an early realization of fusion energy by addressing key physics and engineering issues for ITER [5] and demonstration fusion reactors (DEMO) [6, 7] by utilizing JT-60SA. Figure 1 is a schematic view of the JT-60SA tokamak. The JT-60SA project has been implemented since 2007 under the framework of the broader approach (BA) agreement as well as the Japanese national fusion programme (NA). The overall implementation of the BA activities is directed and supervised by the BA steering committee (SC), and examined by the Project Committee from a technical point of view. The European Union (EU) and Japan each designates an Implementing Agency which substantially carries out pertinent activities for the project provided in the BA agreement. The European Implementing Agency (EU-IA) is Fusion for Energy (F4E) and the Japanese Implementing Agency (JA-IA) is QST. The project team (PT) coordinates the implementation of the project between the EU-IA and the JA-IA.
