The paper briefly describes SATURN code for the numerical simulation of 2D and 3D timedependent and timeindependent neutron transport and nonlinear energy transport by gammas, ions, electrons and fastmoving charged particles. The transport equation is solved in kinetic and diffusion approximations. Code SATURN is oriented to simulations on modern distributedmemory multiprocessor supercomputers. The main ideas on which the code is based are described. Physicomathematical models and mathematical methods used to solve the abovementioned classes of multidimensional problems are formulated, as well as paralleling algorithms are described.Keywords: twodimensional and threedimensional problems of neutron and Xray transport, kinetic and diffusion multiplegroup approximation, SATURN code, difference schemes, paralleling algorithms.
