      The paper gives a brief description of SATURN-3 codes, designed for numerical solution of 2D and 3D stationary and nonstationary linear problems of neutron transfer and nonlinear problems of energy transfer (by photons, ions and electrons).
      The paper also states principal methodical propositions, forming the basis of SATURN codes. The main physical-and-mathematical models are formulated, the statements of mathematical techniques, used for solving some classes of multidimensional problems are described. Computed data for test problems are presented.
