Abstract

Abstract. A special feature of nuclear energy production is the time of the process of controlled change in reactor power. Ensuring the stability of the nuclear power unit core when its power changes is a complex problem that can be solved by achieving shifts in the permitted range of AO in time. This allows to change the reactor power with maximum stability of the energy release in the core and reduces the error in modeling the static and dynamic properties of the nuclear power unit. The proposed automatic control system for changing the power of a nuclear power unit with a pressurized water reactor makes it possible to prevent fluctuations in the technological parameters of the reactor when switching control programs. Keywords: Automatic control system, axial offset, reactor power, nuclear power unit, pressurized water reactor.
