Wire & Cables for the Nuclear Market
AMS Informal CRP Meeting on Cables
AMS Technology Center
Knoxville, TN, USA 2011-08-02
Habia have provided wire and cable solutions to the nuclear industry for over 25 years Our experience as a major supplier in the world enables us to use pioneering materials which are able to meet the majority of internationally recognised nuclear specifications
Wire & Cable Solutions for the Nuclear Market
Nuclear Application: Yonggwang 5 & 6
The first contract for ’new build’ was awarded to Habia Cable by KHNP after a successful LOCA test. Performed to the profile outlined by KEPCO and the IEEE323/1974 and IEEE 383/1974 specifications All special cables were supplied for the 600/1000v systems and were manufactured with the new thin wall, halogen free, reduced fire propagating materials
We are a approved supplier to some major OEMs such as Areva, Kepco, AECL, Cogema, Magnox etc We have established supplier agreements with major operators such as KHNP, Tractebel, Vattenfall, TVO, EON, British Energy etc

Material Specification Properties
Design Flexibility
Because Habia uses higher temperature rated insulation materials than standard nuclear approved cables, the wire will have a higher current rating
This means that in many cases the
system designer has the choice of reducing the wire size and hence the cable size, or increasing the current for the same wire size
Note: If the wire size is reduced this
will increase circuit resistance and hence increase volt drop
Weight & Size – Habia Solution
Habia’s low weight/small size cables offer significant benefits to the end user and builder:
Improved Performance - Lighter Cables - Lighter Cable Trays and Raceways - Lighter Glands and Connectors Improved Space Envelope - Smaller Cables - Smaller Cable Trays and Hangers - Smaller Bulkhead Penetrations Design Flexibility - Increased Current Carrying Capacity - Easier Installation
Benefits of Habia Cable’s Thin Wall Materials
XLPE/CSPE Cable
Diameter: 28mm
Weight: 950 kg/km
Temp Rating: 90deg.C
Habiatron Concept Cable
Diameter: 20 mm
Weight: 620 kg/km
Temp Rating: -40/+125deg.C
Typical example - 14 pair 0.75 sq.mm screened
35% weight reduction and 28% size reduction
New Nuclear Market Strategy
Habia´s Owner Beier Alma Group has decided to
work out a new strategy for Nuclear market during
Autumn 2011
But we have started with some qualification in
advance.
New Qualification
Habia Cable are currently undergoing trials to
develop and test a cable concept to meet 60 year
life acc to IEEE 383:2003 according to the Kepco
LOCA profile. This product is targeted at the new
build of generation III and IV reactor types but also
at the nuclear market for upgrades, modernisation
etc to fit with existing interconnection systems.
Step 1 Activation Energy
First step is to decide the Activation energy for 5 different
materials (Arrhenius method will be used).
–- PEEK
–- XLPE type 4
–- XLPE type 5
–- Megolon
–- Polyimide
Time Schedule: -Test programs are ready.
-Thermal Aging starts in September 2011
Step 2 Qualify for 60 years
Second step is to qualify cables
–Class 1e Cables •Thermo couple 90C (194 F)
•Coaxial Cable RG 58 90 C (194 F)
•Power cable 125C (257F)
–Non Class 1e Cables •UTP-cable (cat. 5e) 60C (140 F)
•Hydrogen Igniter Cable 90C (DBE)
Time Schedule: –Planned completion: Dec 2012.
–Test program not finnished
