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

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

Step 3 Alternative

Compounds/Suppliers

Third step is to Evaluate alternative Compounds and

Suppliers

-Thermal Aging Internal at Habia are ongoing for most materials

Time Schedule: Not finished
