Products
Electrical Penetrations for Nuclear Power Plant Containment Structures
Electrical Penetrations enable the passage of all types of cables through the containment structure, maintaining the integrity of the sealing in all operational scenarios (normal or during an accident), while simultaneously ensuring the continuity of electrical circuits.
Connectors & Severe Accident Connections
Mirion IST France has developed special connections with mineral-insulated cables, as well as connectors and electrical penetration modules to ensure data transmission in the event of a severe accident resulting from reactor core meltdown.
Severe Accident Thermocouples
Severe accident thermocouples are applications directly derived from severe accident Lines. They are used for specific purposes such as detecting vessel rupture, monitoring the operation of hydrogen recombiners, and more.
Fault Processing Cabinets
Any change in the state of a contact inside the reactor building is transformed into an audible and visual signal according to a standardized sequence. The signal is transmitted to the control room and displayed on the control panel. Fault processing cards are grouped in cabinets with their protections and flashers. They are assembled on racks using connectors with card guides. The Fault Processing Cabinets are qualified for seismic resistance.
