Abstract
The engineering design of ITER was completed, based on the world-wide physics and engineering R & D's conducted in the 9 years international joint work. ITER has the main scientific missions such as; to achieve inductively driven or non-inductively sustained burning plasmas at a sufficiently high energy multiplication factor Q≥5_??_10; to integrate fusion technology; and to test the fusion nuclear components such as blankets. An acceleration plan of fusion energy development is investigated on the basis of the ITER program. The key subjects of future fusion development are the steady state sustainment of high beta plasmas, material development, and demonstration of electricity generation and tritium breeding blankets.
