The Method of Control of Nuclear Power Plant with VVER-1000 Reactor in Maneuverable Mode

摘要

An improved system of automatic power control of nuclear power plant with VVER-1000 reactor is presented. This method will allow one to operate a nuclear power plant while maneuvering to maintain the balance of power in the energy system of the country during the day. A condition of successful and safe operation of the nuclear power plant is to maintain a constant axial offset. For this purpose for the first time it was proposed to stabilize the temperature of the coolant at the inlet of the reactor core as well as to reduce the amplitude of movement of the regulatory group of control rods. A basic scheme of the improved system of automated control is proposed. The results of numerical modeling are presented.
