Fusion research and development in the ITER, 1

Significance of fusion research, the subjects and results of researches in the world, International Thermonuclear Experimental Reactor (ITER) project and Broader Approach (BA) activities are stated. The principle of DT fusion and blanket is explained. The main line of research, the tokamak, has been contributed to the core plasma researches with DIII-D, EAST, TFTR, JET, JT-60 and T-10, and the engineering design activities with superconducting coil, blankets, divertor, remote control robot, heat and current drive technology. In October, 2007, an agreement of ITER project was reached among the seven participants such as Japan, USA, EU, Russia, India, China and Korea. It will be based in Cadarache, France. The technical objects, main parameters, a bird's eye view of the whole ITER are described. The international fusion energy research center, fusion simulation center and ITER remote control experiment center will be constructed. The engineering experiments and design for ITER are planning.
