Abstract

The design study of the laser fusion power plant KOYO has been conducted as a joint program of universities, national laboratories, and industries in Japan and also with international collaborations. In the design of KOYO, the gain scaling of direct drive implosion with 0.35 micrometers wavelength laser light is used. A driver of diode pumped solid state laser generates 4 MJ/pulse with 12 Hz and the output pulses are switched to deliver the laser energy success five to four chambers, which operate with 3 Hz. The chamber wall is protected with thick liquid metal which flows down in a SiC woven tube. Following to the conceptual design study, the critical key issues which may affect the technical and economical and economical feasibility of the commercial power plant KOYO have been examined. Research and development of some key technologies have been performed. As the results of the studies on KOYO, it is concluded that thee technical and economical feasibility of laser fusion reactor is well in our scope to reach.
