The coincidentors process the bistable signals from the Wide Range and Power Range Neutron Flux Monitors. They also contain circuits for inserting manual trip signals, bypassing single channels, monitoring non-operate conditions, and test control.
- Process the bistable signals from the Wide Range and Power Range Neutron Flux Monitors
- Provide indication of bistable status from all four Wide Range and Power Range Monitors
- Majority voting logic circuits are used such that two out of the four monitors must indicate the condition before the output is passed to the plant systems
- To meet single failure criteria, all logic circuits are duplicated and the outputs must match before alarms and trip signals are passed to plant systems
- Contains circuits for inserting manual trip signals, bypassing single channels, monitoring non-operating conditions and test control
- Chassis is an integral part of the plant's Reactor Protection System
