Radiation Monitoring Systems
Bertin develops RMS chains, complete radioactivity monitoring solutions for nuclear power plants and facilities.
The Grand Carénage, a major industrial program, aims to extend the operating life of French nuclear power plants up to 60 years. Since 2016, Bertin Technologies has taken part in this project by successfully developing, industrializing and installing RMS measurement chains on behalf of EDF (French electricity generation and supply company).
Bertin Technologies RMS chains are complete radioactivity monitoring solutions specially designed for nuclear power plants and any other nuclear facility where high standards are required.
Our state-of-the-art technology enables us to manage complex systems while meeting the most stringent safety and performance standards. RMS chains are composed of the following components: processing electronics (MDU), junction box and detector, plus remote monitoring systems and data management software to facilitate the collection, transmission and analysis of collected information.
Our RMS monitors are equipped with the following components:
- The GM 700, the IC 400 and the MX 33: a carefully selected detection sub-assembly, chosen based on the specific activity to be measured, ensuring accurate and reliable measurements regardless of the type of radiation.
- The MDU: a local processing unit that processes measurement data in real-time. This unit is able to provide detailed information on radiation levels and generate alarms when thresholds are exceeded.
- A junction box that ensures connection and electrical safety between the various components of the monitoring system and facilitates integration into the existing infrastructure.
- The IDU-PB6 and the IDU-A: an alarm reporting unit for the transmission of alarms to central control stations or external alarm devices. This enables rapid reaction in the event of an abnormal situation or if safety thresholds are exceeded.
- Sysview: a local maintenance tool. Allows you to set parameters, place orders or access data on equipment connected to the maintenance software. It can also be used for remote expertise from «clone» files.
