A study is made of discrete ordinate method with artificial dissipation (DDAD-scheme) for solving numerically neutron transport equation in one and two-dimensional geometries. An artificial dissipation is introduced to weaken nonphysical oscillations, appearing when solving transport equation in optically dense media with discrete ordinate method of the second order of accuracy.
