Abstract
As the level of automation of nuclear reactors developed, gradually automatic regulators changed from the level of maintaining individual parameters to group and then to functional-group control. Control algorithms of modern nuclear power plants use functional-group control, which allows to send commands of the common unit level instead of direct commands. Nowadays, design and construction of a new nuclear power plant with lead coolant is underway. To work out the normal operation algorithms and safety algorithms, a simulation system was created that allows installing the developed models of the nuclear power plant (process control object), models of equipment, process equipment on it and combining them in a single interaction environment. This article considers the possibility of using and implementing the control algorithm of a new nuclear power plant with lead coolant, which complements the standard algorithms of the control and protection system for neutron and technological parameters. For this purpose, a pre-prepared model of the reactor plant and models of the CPS equipment were installed on the simulation stand. The models of the control object and the CPS were supplemented with an exchange interface and an algorithm that allows controlling the operating modes of the process equipment at the pre-start and start-up stages of the RP. The result was a developed algorithm that eliminates the direct impact of the RP operator on technological operations during normal operation with the possibility of switching to manual mode when conditions appear that prohibit further operations
