"Severe Accident" Lines & Connectors

Principle

In case of "Severe Accident" due to reactor core melting, the transmission of the critical data cannot be assured by organic cables because of the very high temperature and level of radiations. Special Lines, with Mineral Insulating Cables were developped with connectors and Penetration Modules in order to assure these functions.

The "Severe Accident" Line is a gloval concept, including various components, allowing to assure the transmission of the electrical signal from a detector located inside the containment building up to the control room.
