The three-dimensional heterogeneous transport calculation code GALAXY-Z has been verified through C5G7 benchmark, and good agreement of eigenvalue and power distribution is found between the GALAXY-Z and reference Monte-Carlo code results. As the axial direction calculation method of planar MOC, it is confirmed one-dimensional MOC is more applicable than diffusion method in high heterogeneous geometry.
