Creation of multi-link automatic parameter control systems at nuclear power plants

The rapid development of nuclear power, the popularization of the use of radioactive substances and sources of ionizing radiation in industry requires the creation of tools for the implementation of various ways of regulating the reactor, their regulatory systems or ISAR. The article considers methods of regulation and maintenance at a given level of power of nuclear reactor and electric power of generator. The problem of creation of automatic control systems at nuclear power plants is considered, and the issues of creation of multi-stage systems of multilink regulation are discussed. The main goals of such systems are to achieve permanent performance of nuclear power plants, full control over all ongoing processes and, of course, safety. In the result of the study the article analyses feature of automated control systems. Various approaches to their creation, principles of automation are considered and schematics of the control system are presented. The systems presented suggest the use of a number of sensors to measure current parameters in reactor active zones. The frequency characteristics of continuous and discrete regulators were analyzed. By means of expert evaluation, a reasonable selection of specific measurement tools was made. The measuring instruments in question are state-of-the-art equipment of Russian and foreign production, having a good service life and necessary measurement accuracy.
