RESEARCH OF INFORMATION SECURITY AND TECHNOLOGICAL REGULATIONS OF THE MANAGEMENT PROCESSES OF THE CRITICAL INFRASTRUCTURE OF A NPP POWER UNIT WITH A VVER-1000 REACTOR

Abstract

A brief overview of the technological processes of the critical infrastructure of the NPP power unit with the VVER-1000 type reactor is given using the example of power units 1 and 2 of the South Ukrainian NPP. The purpose of this article is to study the organization of power unit management in different modes, to analyze the structure and volume of information provided to operational personnel from the information and control system, digital software and technical complexes, and other systems, as well as to analyze the complexity of the technological regulations by which management takes place NPP power unit. The object of the research is the process of information support and technological regulations, according to which the power unit of the NPP is managed. The subject of the study is the intensity and complexity of the decision-making processes by the operational staff of the NPP when managing the power unit. The following tasks were solved in this work: The organization of the power unit management process was studied; The main information and control systems and software and technical complexes of the power unit were considered, as well as means of their interaction with operational personnel; The information model, which is used by operational personnel in managing the power unit, is considered. For this purpose, the indicators of the information model, which is used by operational staff to make decisions when managing the power unit, were determined and the volume of control bodies with which the operational staff interacts to manage the power unit was determined. The structure of technological regulations and instructions for power unit management was analyzed and the volume and complexity of these documents were determined; The expediency of research on improving NPP power unit management processes has been determined, namely: in the direction of further research, support systems for operational personnel, their classification, functions and experience of application at NPPs of Ukraine will be considered, with the aim of determining the actual design directions of such systems. It is necessary to determine which support systems have been implemented or are being developed at the present time, which difficulties arise for the operational staff during the management of the power unit, and which of them can be solved with the help of support systems.
