description: The topic of the final qualifying work: "Modeling the effects of WWER reactivity in the Simulink environment".Safety is the highest priority during the operation of a nuclear reactor. To ensure this, special attention is paid to the behavior of the reactor in various neutron power ranges. At the same time, complex feedback effects play a huge role in all ranges, which, under certain circumstances, cause the reactor to have completely new properties of self-regulation and stability. Taking into account the influence of feedbacks on control, called reactivity effects, is an important issue when designing an automatic transfer switch (ATS).This work is devoted to the study of unsteady processes in a reactor using examples of linear and nonlinear models of point kinetics with a different number of groups of delayed neutrons and in the presence of different types of feedbacks. Simulation of transient processes in the reactor under the influence of various control signals was carried out in the Simulink graphical programming environment.Based on the results of the analysis of the reactor behavior, conclusions are drawn about the safety of using these models in the further creation of the ATS system.
