AbstractThe purpose of the study is to study the possibility of Renyi entropy applying to monitor the condition of nuclear power plant equipment and the ability to detect faults in this equipment. In the present work processing of video images obtained with the help of a thermal imaging control system at Rostov NPP is performed. For this purpose a program is developed for the Renyi entropy calculating of the 0th, 1st, and 2nd orders for video images, as well as an analysis of the time variations of the 0-order, 1-order, 2-order Renyi entropy for detecting malfunctions in nuclear power plant equipment. Calculation of entropy indicators allows to obtain important qualitative and quantitative information about the structure of complex physical systems, the features of their dynamic evolution and about the physical processes taking place in such systems.
