223. JT-60SA TF magnet assembly

Sam Davis (Broader Approach Fusion for Energy)

20/09/2018, 14:30

JT-60SA will be the world’s largest superconducting tokamak when it is assembled in 2020 in Naka, Japan (R=3m, a=1.2m). It is being constructed jointly by institutions in the EU and Japan under the Broader Approach agreement. The assembly of its 400-tonne toroidal field (TF) magnet, designed for an on-axis field of 2.25T, will be completed in summer 2018.

After cryogenic testing in Saclay,...

230. JT-60SA Toroidal Field coils procured by ENEA: a final review

Gian Mario Polli (Fusion and Technology for Nuclear Safety and Security ENEA)

20/09/2018, 14:50

Within the Broader Approach Program between Europe and Japan for the early realization of fusion with the construction of the JT-60SA tokamak, ENEA, the Italian Agency for New Technologies, Energy and Sustainable Economic Development, was in charge, among others, to supply ten superconducting Toroidal Field (TF) coils for the JT-60SA magnet system. The related procurement started in 2011 and...

233. Completion of the JT-60 SA Toroidal Field coils tests in the Cold Test Facility

Walid ABDEL MAKSOUD (CEA)

JT-60SA is a fusion experiment which is jointly constructed by Japan and Europe and which shall contribute to the early realization of fusion energy, by providing support to the operation of ITER, and by addressing key physics issues for ITER and DEMO. In order to achieve these goals, the existing JT-60U experiment will be upgraded to JT-60SA by using superconducting coils. The 18 TF coils of...

234. Updated Conceptual Design of the DTT magnet system

Aldo Di Zenobio (FSN ENEA)

20/09/2018, 16:00

DTT is the acronym of “Divertor Tokamak Test” facility, a project for a compact but flexible tokamak reactor which has been conceived in the framework of the European Fusion Roadmap. It will be built in Italy and shall act as a satellite experimental facility to integrate the extrapolation of the ITER results to the EU-DEMO machine. It is thus mainly aimed at the exploration of different...

31. From manufacture to assembly of the ITER central solenoid

Dr Paul Libeyre (ITER Organization)

Magnets and Power Supplies

The Central Solenoid (CS), a key component of the ITER Magnet system, using a 45 kA Nb3Sn conductor, includes six identical coils, called modules, to form a solenoid, enclosed inside a structure providing vertical pre-compression and mechanical support. Procurement of the components of the ITER CS is the responsibility of US ITER, the ITER Domestic Agency of the USA, while the assembly of...

236. Development and qualification of ITER current lead electrical insulation

Xiongyi Huang (Tokamak Design Division Institute of Plasma Physics Chinese Academy of Sciences)

20/09/2018, 16:40

ITER high temperature superconducting current lead is a critical component for the magnet system, which has the benefit of reduction in the heat load of the cryogenic system compare with the conventional current lead. The current lead is located in the coil terminal box and dry box in the ITER feeder system. As a warm to cold transition section, the current lead fed the huge current from the...

232. Multi-scale 3D modelling of a DEMO prototype cable from strand to full-size conductor based on X-ray tomography and image analysis

Ion Tiseanu (Plasma Physics and Nuclear Fusion National Institute for Lasers Plasma and Radiation Physics)

20/09/2018, 17:00

The design of a superconducting magnet system of a fusion reactor candidate is usually based on the Cable-in Conduit Conductor (CICC) concept. CICC consist of complex structures with several hundreds of highly packed, multistage twisted superconductor and copper strands, cooling structures – all wrapped in thin steel foils and jacketed in relatively thick stainless-steel pipes. As recently...
