The CAAS-3S is a next generation system based on operational excellence established over forty years.
The CAAS-3S is a next generation system based on operational excellence established over forty years. The new design is based on the highly reliable analog signal chain used in the probe design for the previous EDAC-2 and later EDAC-21 products which have had successful safety records and very low false alarm rates. This new system addresses the next several decades of facility operation.
RANGE OF COVERAGE SCENARIOS
Detection capabilities include gamma-only, neutron-only, and combined neutron + gamma probes to cover all types of installations and criticality excursions
Use of scintillation technology and ruggedized electronic components provides very high-reliability and allows accident and post-accident monitoring of dose rate
The system is designed to meet SIL2 IEC61511, with full redundancy of the safety channel from probe to alarm output
Tested and proven to detect a criticality event and trigger alarms under seismic conditions
