One of the important key issues is to evaluate the details of the energy deposition of fusion products on the first wall for the laser fusion reactors. Liquid wall is considered as the first wall. In order to estimate the ablation depth, the ablation mass, and the temperature profiles in the wall, we have carried out the simulation studies including the energy deposition of x rays and the charged particles, the thermal conduction of he first wall materials and the energy absorption of charged particles in the ablated vapor. In the case of chamber radii 2 m, 4m, 8m with a fusion output 400 MJ we have evaluated the ablation of Pb liquid first wall. It is pointed out that the alpha particles on the first wall have a strong effect on the wall ablation.
