Description

At the heart of the WRM 510 wide range monitor resides the DWK 260™ digital wide range signal processing unit that belongs to the Mirion proTK™/260 series of signal processing units for safety critical applications.

The DWK 260 channel can be used with any type of guarded or non-guarded wide range fission chamber to cover more than 10 decades of neutron flux during all modes of reactor operation.

Hardware and software of the WRM 510 monitor are designed and qualified for use at the level of the reactor protection system.

With the WRM 510 monitor, Mirion provides the complete neutron monitoring system for the wide range from neutron detector to the safety signals for reactor protection and control.
