Mobile Post-Emergency Monitoring System for Nuclear Power Plants

In this paper, a concept of designing the post-emergency system for monitoring the equipment and territory of nuclear power plant after a severe accident was developed. Power and communications network lines are found out as the most vulnerable ones during the accident monitoring, and selfdescriptiveness and survivability and veracity are recognized as system basic parameters. To ensure the self-descriptiveness it’s proposed to equip measurement and control modules with backup wireless communication channels and deploy the repeaters network based on drones. To provide the survivability modules possess the backup power battery, and repeaters appear in the appropriate places after the accident. Moreover an optimization of drone’s location is proposed according to the minimum energy consumption criterion. To ensure the veracity it’s expected to design the noise-immune protocol for message exchange and archiving and self-diagnostics of all system components. Formulas for estimating the reliability level of the post-emergency monitoring system were obtained.
