Progress on research and development towards realization of fusion energy

On the progress in research and development for the realization of fusion energy at the National Institutes for Quantum and Radiological Science and Technology (QST), the Series No. 5 and No. 6 mainly explain the ITER project and broader approach activities. The Series No. 5 (this paper) introduces the following: (1) R&D strategy of fusion DEMO for verification of power generation, (2) ITER project as a large-scale international research cooperation project: development state of the devices whose manufacture is in charge of QST, such as superconducting coils, neutral particle injection heating devices, and high-frequency heating devices, and (3) test blanket module experiment plan where test is performed using ITER.
