Analysis of using complex mathematical models to design nuclear power plants with liquid metal coolant

This article examines the development of control algorithms for nuclear power plants using complex mathematical models that allow for studying the operation of a nuclear power plant in various dynamic modes, especially during start-up and cooldown. The models are based on the change in the physical state of the liquid metal coolant. The article reviews the operating experience of nuclear power plants with liquid metal coolant and the application of complex mathematical models. Analysis of papers and online resources on the topic. Recent research has been used as a science and technology base for the development of a new generation of nuclear power plants with liquid metal coolant based on innovative solutions with increased nuclear and radiation safety, reliability, and improved weight, dimensional and operational parameters. To develop a nuclear power plant ahead of schedule and conduct comprehensive tests and research before its large-scale production, it is required to develop comprehensive mathematical models. Every experiment with a nuclear power plant is first tested on a computer model. This allows for safe and low-cost research of the reactor’s behavior in various modes, including emergency, for further development of control algorithms.
