Critical issues on laser fusion reactor with a liquid wall are discussed. Formation of aerosols after laser shot was studied experimentally and theoretically. Our simulation results for formation of aerosols agreed with experimental results obtained with electric discharge through a thin lead membrane. Formation of micro particles is discussed basing on experimental results obtained by backside irradiation of a lead membrane. Protection of beam ports of the laser fusion reactor with a liquid first wall is described. A magnetic field generated with a pulse current successfully shielded the tip of beam ports from alpha particles. A continuous protective liquid LiPb flow controlled with cascade scheme was formed as the protective first wall of KOYO-F.
