Abstract

Fast ignition scheme in laser fusion enables the sufficient pellet gain for a commercial operation (G∼100) with small input energy. To make full use of this property, a new design concept, Fast ignition Advanced Laser reactor CONcept with a Dry wall chamber (FALCON-D), was proposed. In this paper, the analysis result of the core plasma dynamics and the thermomechanical response of the dry wall are discussed. For the former analysis, we performed numerical simulations by a 1-D hydrodynamic code and demonstrated the pellet gain G100 with the input laser energy of 400kJ. For the latter, thermomechanical analysis by a FEM code was carried out. It indicates that the temperature increase is not a concern but fatigue failure may be a problem. Other threatening effects (e.g, blistering, carbon irradiation) are also concern. Highly-engineered materials (e.g. UFG-W) can solve these problems. It is difficult to estimate accurate lifetime of the first wall due to many uncertainties in the material properties. Further quantitative analysis based on the reliable experimental data is required.
