Description
At the heart of the IRM 510 intermediate range monitor resides the DAK 260- g digital startup signal processing unit that belongs to the Mirion proTK™/260 series of signal processing units for safety critical applications.
The DAK 260-g channel can be used with any type of neutron ionization chamber and a matching current-to-frequency converter to cover up to 10 decades of neutron flux during reactor start-up.
Hardware and software of the IRM 510 monitor are designed and qualified for use at the level of the reactor protection system.
With the IRM 510 monitor, Mirion provides the complete neutron monitoring system for the intermediate range during reactor start-up from neutron detector to the safety signals for reactor protection and control.
