The Broader Approach (BA) activities complement the ITER project
and aim to accelerate the realisation of fusion energy.
The work includes the construction of an advanced fusion device,
research into durable materials for use in future devices,
and preliminary work on the future Demonstration (DEMO) reactor.
International Fusion Materials Irradiation Facility/Engineering Validation and Engineering Design Activities (IFMIF/EVEDA)
A commercial fusion reactor will need materials that are resilient enough to maintain their mechanical properties for a long time while withstanding the extreme conditions inside a fusion reactor. The IFMIF/EVEDA project is the Engineering Validation and Engineering Design Activities phase of IFMIF, a facility to produce a source of neutrons. This source will be able to test materials for DEMO and other future fusion devices. The project aims at providing all data necessary for future decisions on the construction, operation and decommissioning of IFMIF.
International Fusion Energy Research Centre (IFERC)
The IFERC project comprises of three subprojects:
● The Computational Simulation Centre (CSC) provides high power computer resources for JA and EU scientists in order to conduct simulations of plasmas, fusion materials and technology for ITER, JT-60SA and fusion reactor in general (e.g. DEMO).
● The Fusion reactors Design and R&D Activities includes both design and R&D activities in breeding blanket materials and tritium studies, and are concentrated in identifying DEMO requirements.
● The ITER Remote Experimentation Centre (REC) was conceived as a remote experimentation room for ITER, with the aim of allowing scientists in Japan to participate remotely to future ITER experiments, including their preparation, visualisation of data and plant status in real time, and the transmission and detailed analysis of results.
Satellite Tokamak Programme (STP)
The STP project involves the construction of JT-60SA, a fusion device under construction in Naka, Japan. When complete in 2020, it will be the largest and most advanced operational fusion machine in the world, about half the size of ITER and equipped with superconducting magnets. Like ITER, JT-60SA will be a “tokamak”, a tyre-shaped machine that holds the plasma in place using magnets. JT-60SA will sustain plasma in conditions that can produce the fusion reaction for up to 100 seconds at a time. Through its experiments, scientists will gain knowledge of how to keep the plasma hot and stable as well as how to handle the power produced through fusion. The project also aims to contribute to the early realisation of fusion energy by supporting ITER, largely through helping it run efficiently and reduce risks. In November 2019, the ITER Organization, Euratom, and Japan signed a collaboration arrangement that will enable them to share knowledge and expertise to reduce risks when building and operating ITER. The construction and operation of the machine is supported both by the BA Agreement and by the Japanese national fusion programme. One unified JT-60SA Experiment Team will operate the machine.
