A Criticality Accident Alarm System (CAAS) is an alarm system for prompt evacuation of personnel in the event of a criticality event. Mirion offers CAAS systems for a range of applications from wide-area coverage in large buildings or across facilities to stand-alone self-contained fixed or mobile units, along with the alarm systems, software, and services.
Criticality Accident Alarm Systems (CAAS) are required in nuclear facilities where an accidental criticality excursion could result from operational processes.
The CAAS-3S unit is a criticality accident alarm system (CAAS) as defined by the relevant industry standards. The system is designed to monitor areas where a potential criticality excursion could take place and alarm rapidly for the prompt evacuation of personnel in the event of a criticality accident.
