JT-60 SA
Cryostat ready for Europe-Japan tokamak
18 Sep 2017
The cryostat vessel body of the JT-60SA tokamak has been successfully manufactured and pre-assembled at a factory in Spain, and will soon be transferred to the JT-60SA site in Naka, Japan, for final installation.
The European Domestic Agency/CIEMAT/Asturfeito S.A. team in front of the JT-60SA cryostat vessel body.
This large containment vessel, formed from 12 sectors, will provide thermal insulation and a vacuum environment around the machine's magnet components.
The tokamak is part of the agreement signed between Japan and Euratom, and implemented by QST Japan and the European Domestic Agency for °ÄÃÅÁùºÏ²Ê¸ßÊÖ. It represents an upgrade of a previous tokamak at the Naka facility, designed to support the operation of °ÄÃÅÁùºÏ²Ê¸ßÊÖ and to investigate how best to optimize the design and operation of fusion power plants built after °ÄÃÅÁùºÏ²Ê¸ßÊÖ. First Plasma is planned for 2020, at the end of a six-year assembly and commissioning period.
The cryostat vessel body has been procured as a voluntary contribution to the Broader Approach Agreement by Spain (through its national fusion research centre CIEMAT) and manufactured by Asturfeito, S.A. Once assembled in Japan, it will be capped by a top lid procured by QST.
