An integrated two-dimensional ablation simulation code DECORE-2D (DEsign COde for REactor) has been developed to estimate the environment of the liquid wall chamber of KOYO-fast. Density profiles of ablated lead are estimated using DECORE-2D for the case of first ignition with 200 MJ fusion power output. To discuss the stagnation of ablated materials in the chamber, the divergence of ablated material with phase change was analyzed in two-dimensional planar geometry. The spread angle of a plume obtained by this simulation is roughly 1◦. This result indicates that the stagnation of ablated materials can be discussed with straight flows from tiles tilted by 30◦ to the tangential direction.
