Bertin Instruments was awarded for the delivery, installation and commissioning of a new sophisticated environmental and emergency radiation monitoring system for two nuclear power plants in Czech Republic: Temelin (2 VVER reactors, 2.000 MW capacity) and Dukovany (4 VVER reactors, 2.000 MW capacity). Both monitoring systems have been fully operational since October 2016.
For redundancy and safety reasons, all measurement data had to be transmitted to two locations:
- the nuclear power plant’s control room
- a mobile control center located in an emergency vehicle
Both the nuclear power plant control room and the mobile emergency vehicle have independent database servers and were fully equipped with software for data reception, processing and alarm management. With a reception signal to noise ratio of -143 dB, Bertin’s proprietary radio transmission system is the only worldwide system which can cover large areas as required in the tender, without using a repeater. Due to the use of specific licensed frequencies, the data transmission will reliably work even in a catastrophe scenario, when public communication frequencies and infrastructures is down or crowded.
