2050年にトカマク型実用核融合プラントを稼動させるために　－ITERの役割とその後の展開－　2.核融合プラント実現への道

抄録

In this section, the target performances of fusion reactors and their development scenarios are described. Fusion reactors for commercial use should be competitive not only in terms of cost of electricity but also in the various characteristics of plant. The requirements of commercial plants are summarized in comparison with fusion's competitors. An example of a development scenario, which was authorized by the Atomic Energy Commission of Japan (AEC) in 2000, is reviewed in Section 2-2. This plan should be revised if earlier realization of fusion energy is desired. A new plan and revised designs of the demo-plants are introduced and compared in Section2-3. In all cases, the performances required for first generation commercial plants must be achieved or clearly established during the demo-plants' operation phase. In light of these requirements, a basic policy toward the development of fusion energy is stated in Section 2-4.
