In order to increase the service life of NPPs is proposed to change the power of the nuclear reactor depending on the needs of consumers. However, power maneuvering increases the risk of an emergency situation, since it is very difficult to maintain a steady state of the reactor when moving from one power level to another. For this, it is necessary to adapt the methods of operational control when changing the power of a nuclear reactor. An approximation model is proposed, with the help of which it is possible to improve the system of automated power control in case of internal disturbances of a nuclear reactor. The change in reactivity that occurs as a result of a change in the concentration of xenon when maneuvering the power of a nuclear power plant was attributed to internal disturbances. An approximation model of the processes was built using the Padé approximation.
