Future prospect and issues of nuclear fusion power reactor, in case of the first wall

Kurihara, Ryoichi

Research and development of nuclear fusion reactors have been internationally conducted to obtain the energy source in the middle of 21st century. The nuclear fusion reactor has safer characteristics than the nuclear fission reactor. But its structural materials are subjected many severe mechanical conditions such as very high temperature, 14MeV neutron flux. This paper describes the prospect and issues in the fusion power reactor design study from the point of view of the first wall.
