Temperature Regulation Contribution during the Power Control of the VVER-1000 and VVER-1200 Reactors in a Load-Following Mode

Abstract
Thermal power plants are the most flexible concerning power level regulation. Furthermore, nuclear power plants are preferentially used for base load. Presently, electrical power systems require continuous adjustment of the nuclear energy produced. Consequently, it becomes imperative to adapt nuclear power plants to new specific operating conditions in load following operation. To solve this problem, advanced algorithms are proposed for the improvement of power control at nuclear power plants. Therefore, a special algorithm has been developed in which temperature regulation is introduced to reduce the amplitude impact of existing regulators, such as control rods and dissolved boric acid. The effect of temperature regulation on load following modes for VVER-1000 and VVER-1200 reactors, on the axial offset, and on the volume of water exchange required to control the reactor power is analyzed in this work. It has been found that the use of temperature regulation to operate nuclear power plants in load following modes makes it possible to keep the current axial offset in the recommended area and to reduce water exchange by more than 40 %.
