In the case of a severe accident, it is required to monitor the level of hydrogen and other combustible gases in order to take the right decisions and maintain the containment integrity.

The Multi-functional Containment Atmosphere Monitoring System (HERMETIS) operates in the conditions of core melt accidents.
It provides all necessary information for the severe accident management (SAM) and emergency planning.

Your benefits

  • Fully-qualified combustible gases monitoring for core melt accidents (only one system for design basis and beyond-design basis accidents)
  • Superheating of micro sample enables required accuracy for steam and hydrogen measurements
  • Monitors the efficiency of combustible gas control systems (hydrogen reduction and containment mixing)
  • Provides information for SAM and emergency planning (for example to maintain inerted containment conditions at high hydrogen concentrations)
