Abstract
There is a discrepancy between the generation and consumption of electric energy during the daily cycle in Ukraine's power grid. The total share of installations intended to regulate the load of the power system is very small, therefore the adaptation of the operating power units of the nuclear power plant to the new specific conditions is urgent by creating an automated power control system in the power unit in maneuvering modes. In this paper, a comparative analysis of the traditional power control programs of the power unit (programs with constant steam pressure in the second circuit (Ps = const) and the constant average temperature of the heat carrier in the first circuit (tav = const)) is considered in the manual mode in terms of reactor stability. The axial offset characterizes the uniformity of energy release over the height of the active zone of the reactor, and, consequently, its stability. The unevenness of the neutron field of the reactor reduces the economic performance of the reactor plant and in some cases can lead to pre-emergency and emergency situations. Key
