This paper presents the modeling of a 3-D Supercritical Water-Cooled Reactor unit cell.  The pre-homogenization of the geometries allows us to reduce the size of the problem without affecting significantly the results of lattice cell calculations.  The differences observed between the results of 2-D and 3-D calculations are explained by the isotropic reflective boundary conditions associated with the Z surfaces in the 3-D case.  The lattice code DRAGON, which has the ability to solve the 3-D neutron transport equation, has been used in this study.
