The thesis deals with the theoretical study of the possibility of the power control of the perspective fast reactor that works in the self-sustained mode of the nuclear burning wave (NBW). In our study the power is controlled by means of the radial neutron reflector. The study was conducted by simulating the nuclear burning wave propagation along the axial direction of the cylindrical reactor with U-Pu fuel cycle and Pb-Bi eutectics as coolant and radial neutron reflector. The deterministic approach based on the numerical solution of the problem of the neutron transport in the multiplication medium, with constantly changing isotope composition, was used for simulation of the nucleus-neutron processes in such reactor.
