Requirements and operational interface of JT-60SA superconducting coils

Yoshida, Kiyoshi; Tsuchiya, Katsuhiko; Kizu, Kaname

Japanese government (JA) and European commission (EU) are establishing so-called "Broader Approach Program" toward early realization of fusion energy based on tokamak concept. JT-60U modification program to a superconducting device can be a strong satellite tokamak program in the BA with a new device name "JT-60SA (JT-60 Super Advanced)". The design concepts and rules of JT-60SA superconducting coils are followed to these in the ITER project. Parties in JA and in EU can use the common design concepts and rules these have been developed during the Engineering Design Activity (EDA) in the ITER. It is possible to avoid many developments to design the superconducting coils in JT-60SA. This paper descries the requirements and the operational interface of the JT-60SA.
