Enhancing Nuclear Safety with Neutron Counters
Boron-Lined Proportional Counters (CPNB) from Photonis measure neutron radiation in a wide range of nuclear reactors and neutron source applications where reliability and safety is paramount. These counters can operate at temperatures of up to 200°C.
Features of the Boron-Lined Proportional Counters include:
- Detection of thermal neutrons in pulse mode
- Exceptional safety features
- Fast counting times and long detector life
- Customization to meet user-specific requirements
These devices work in pulse mode and feature a watertight HN connector. Photonis’s proprietary B-10 coating, produced through the Chemical Vapor Deposition (CVD) process, provides unmatched durability, excellent pulse resolution, and high sensitivity. This coating ensures that these counters meet safety instrumentation requirements where they have been installed in over 100 nuclear power plants worldwide. Given the challenging operating conditions of CPNBs, Photonis also recommends the use of an integrated mineral-insulated cable, designed specifically for the detector to minimize noise and required maintenance, while extending the useful life of the detector in high gamma environments.
