Reliability and survivability models of integrated drone-based systems for post emergency monitoring of NPPs

This paper presents the approach to research integrated drone-based systems for post emergency monitoring of NPPs as systems with a multi-level degradation. Reliability block diagrams of the systems are built. Degradation levels, conditions which determine them and formulae for calculating the reliability functions of the systems on these levels are proposed. The possibility of using developed models for research systems with a multi-level degradation and using drones are shown
