Methods of calculating evolution of the stress-strain state of the equipment of nuclear power plants taking into account the destruction of areas of action of seismic loads

Designed iterative-analytical theory of spatial multi-layer constructions in view of the possible destruction of the material layers of shells. A mathematical model of crack propagation in the construction of nuclear power plants, taking into account the basic parameters of the seismic loading containments and NPP equipment. An geometrically and physically nonlinear equations.

Development of software for risk operating analysis of electric power subsystems with nuclear power plants

The analysis of the conditions of operation of NPP with auxiliary systems in modern EPS of Ukraine was performed. The most probable set of events (incidents) that cause accidents in EPS with NPP was determined. The structure of risks of electrical connection of NPP and TPP with power system and blackout of auxiliary system of power plant under extreme external influences was formed.

The Stress Monitoring System for the Main Pipeline, Based on Magnetic Elastic Method

The monitoring system includes equipment, methods, and software. It was designed for the following purposes: Measurement of mechanical stress within the main pipeline, located in potentially dangerous areas. Transmission of measurement data into operator’s server. Graphical representation of the current stress distribution in a horizontal axis of a pipeline. Graphical representation of stress changes in the points of measurement over time.

System control by the operability, the survivability and the safety of the complex technical systems in the conditions of different nature uncertainties and destabilizing risk factors

There is proposed system control by operability, survivability and safety of complex technical systems (CTS) under the influence of destabilizing risk factors, the conceptual and information uncertainty as the system of timely decisions making on operational prevent potential accident and catastrophic situations.
