The Electrical Penetrations ensure the passage of all types of cables through the containment enclosure, maintaining the integrity of the seal in all cases of operation (normal or accidental) while simultaneously ensuring the continuity of the electrical circuits.
Mirion IST France has developed special links, with mineral insulated cable as well as connectors and electrical crossing modules to ensure data transmission in case of a severe accident, due to the melting of the reactor core.
Severe Accident Thermocouples are made directly in application from the Severe Accident Lines. They relate to particular applications such as: detection of tank rupture, operation control of hydrogen recombiners, and so on...
Any change in the state of a contact inside the reactor building is transformed into an audible and light signal following a standardized sequence. The signal is retransmitted to the control room and displayed on the control panel.
