K1 Qualification of 8NA Series junction boxes for EPR

Compliant with RCC-E 2005 design and manufacturing code, those new junction boxes integrate a robust cable gland with 360° screen termination mechanism that ensures perfect ground continuity and high shielding performances.

K1 is the qualification for inside containment safety related equipments, that have to demonstrate their ability to remain functional under accidental and post accidental conditions, including in case of a Loss of Coolant Accident (LOCA). K1 qualification of new 8NA Series junction boxes for EPR has been performed by SOURIAU, and validated by EDF SEPTEN.

New 8NA Series junction boxes for EPR are derived from existing 8NA Series K1 qualified interconnect systems, which have been used for decades in numerous nuclear power plants worldwide.

Available in a large variety of Input / Output configurations, the new 8NA Series junction boxes for EPR are fully compliant with the other existing products from 8NA Series, including connectors, cable assemblies and flexible metallic conduits.
