Background. The priority idea of managing technogenic risks of hazardous energy facilities of the Russian Federation on the basis of measuring diagnostic information is to form various activities for scientific substantiation and instrumental support of the admissibility of production conditions and risks, current functional safety and operational reliability, environmental acceptability of facilities, production technologies, engineering systems, networks and structures, primarily equipment for nuclear power plants, oil and gas industry according to their actual technical condition.
Materials and methods. During the period of long-term operation of the specified equipment, a distinctive feature of the modern risk management methodology for the operation of hazardous production facilities is the desire to use promising methods for assessing possible hazards based on the simulation of destructive and fire hazardous events, degradation processes of service properties, as well as probabilistic forecasting of the moment of transition of a specific type of equipment or its structure in critical condition and subsequent destruction.
Results. The composition of the information model of the management system for man-made risks of potentially hazardous objects based on risk-oriented integral assessment of man-made safety and economic benefits is shown. The article presents a positive perspective for managing technogenic risks of energy complex objects when developing programs for their maintenance and repair, taking into account measuring diagnostic information about controlled objects.
Conclusion. Proposals for the systematic improvement of the quality of man-made risk management at hazardous energy facilities in the fuel and energy complex have certain technical and economic advantages, namely: scientifically grounded optimization of costs for all measures to manage risks of industrial operation of a power facility during its long-term operation; the possibility of evolutionary development of the system for diagnosing and predictive risk assessment; the possibility of further development of the safety culture system for the operation of an energy facility.
