Fire Retardant Non Corrosive Cables for Nuclear Power Plants
Introduction
� At the beginning, PVC & Hypalon®
were used in Nuclear Power Plant
� At that time Fire properties were
acceptable
Bratislava – September 27, 20062
� But corrosivity, toxicity, and smoke were tremendous
Fire Retardant Non Corrosive (FRNC) Cables
Bratislava – September 27, 20063
� NC means Non Corrosive
(or Halogen Free)
� FR means Fire Retardant
40 years experience for 1E & non 1E …
� 1980’: First generation of FRNC cables in France
� 1990’: Openning of Central & East Europe market with supplyof Temelin, Bohunice, Dukovany, Kozloduy
Improvement of Fire Performances versus Special painting on existing cables
2000’: Aecl, Minatom & General Electric now use FRNC Nexans cables
Bratislava – September 27, 20064
� 2000’: Aecl, Minatom & General Electric now use FRNC Nexans cables
� Today: FRNC cables are available for 60 years lifetime requested for EPR
reactor (Areva)
During all these years, close partnership between Nexans and EDF (Electricité de France)
Flame Retardancy - IEC 60332-1
� Single burner (IEC 695-2-4/1)
� Sample of 600 ± 25 mm
� Temperature : ± 400 °C
� Test duration : according to the cable
diameter (60 to 480 seconds)
Bratislava – September 27, 20065
� Results: after test the cable should
stop burning and the burnt length
should not reach 50 mm under the A mark
Fire Retardancy - IEC 60332-3
• Test on bunched cables
• High performances of FRNC (Fire
Retardant Non Corrosive) Cables
• Temperature: 800 °C 22 (A) : 7l/m of burning material
23 (B) : 3.5l/m
24 (C) : 1.5l/m
Bratislava – September 27, 20066
24 (C) : 1.5l/m
• Test duration22 (A) : 40 mn
23 (B) : 40 mn
24 (C) : 20 mn
� Results: no burning over 2.5m height
from the burner.
Smoke - Opacity - IEC 61034
� Smoke opacity measurement in a
27m3 room, during the burning of a
cable sample (25 min), and 40 min after burning is completed

- To simulate the most severe postulatedconditions of a design basis event andspecified conditions of installation(IEEE 383 par. 1.3.5.3)
Test design Basis event3
The type testing for design basis event conditions shall involve both aged and non aged
samples (IEEE 383 par. 1.3.5.2)
2 scenariis because the design basis event
may occur at any time (IEEE 383 par. 1.3.5.1)
