ABSTRACT

• Cable penetration assemblies (CPA) designed for applications

in safety-related systems of nuclear power plants (facilities) shall

follow general and specific design principles described by

the standard IEEE Std 317-2013. CPA perform two important general

safety functions. The first intended safety function is ensuring

the pressure boundary of the containment and, in the case, keeps

the harsh environment generated by accident conditions just inside

hermetized zones. The second intended safety function is providing

a conductive channel through a wall for medium voltage, low voltage,

and coaxial/signal/optic cables in any service and postulated design

conditions.

• Although, the design of CPA is represented as passive component, it

is formed into several functional groups comprise polymeric

compounds, metallic and ceramic components integrated one tubular

piece.

ABSTRACT

• In general, the mission time of CPA is limited primarily by used

polymeric materials that are mostly sensitive for thermal and radiation

ageing. Equipment qualification process as is recognized in the new

dual-logo standard IEC/IEEE 60780-323:2017 defined principles for

determination of the qualified life. Important part of the process is

performance of equipment type testing program during whose shall

be simulated, in part, accelerated ageing conditions of thermal,

radiation, wearing, vibrational (etc.) effects occurred during mission

time (qualification life), thus, environmental conditions generated by

accident conditions (severe radiation; sharp thermo-hydraulic

elevation). Qualification process of CPA for long-terms mission is

demanding and results are frequently wide scattered and ambiguous.

Therefore Condition Monitoring (CM), as is introduced by IEC/IEEE

60780-323:2017, should always accompany qualification process.

ABSTRACT

• Company Kabelovna Kabex (a.s.) are developing the new generation

of CPA that are specifically designed for applications in nuclear

facilities towards long-term service. Inseparable part of equipment

qualification program is determination of CM indicators, nomogramig

of predictive indexes, prescriptive guide for follow-up plant in-situ data

gathering and benchamarking surveillance program encompassing

natural aged witnessing samples. The complex qualification program

involving ongoing qualification fully complies with nuclear quality

requirements as are determined by Czech nuclear legislation.

Equipment Qualification

Concept in Four Steps

A design qualification program shall include:

1) Qualification criteria

2) A program demonstrating qualification using testing, analysis,

operating experience, or a combination of these methods

3) Evidence of successful qualification

4) A documentation file containing (1), (2), and (3)

rem-ten013-19.rcz

Concept in Four StepsThe EQ program shall include an assessment of aging effects on

equipment. Significant aging mechanisms shall be identified and

addressed as part of the program. Significant aging mechanisms are

defined as ones satisfying four criteria:

1. An aging mechanism promotes the same failure mode during

normal environmental conditions and from exposure to abnormal

or design basis event service conditions.

2. The aging mechanism adversely affects the ability of the

equipment to perform its safety.

3. The deterioration caused by the aging mechanism is not

amenable to assessment by in-service inspection or surveillance

activities.

4. In the normal service environment, the aging mechanism causes

degradation during the design life of the equipment that is

appreciable compared to degradation caused by

the design basis events. rem-ten013-19.rcz

Concept in Four Steps

Qualified life shall be established for equipment with significant aging

mechanisms.

Qualified life is equal to design life for equipment with no significant

aging mechanisms.

insulated electric conductors,

conductor seals, module seals

(if any), and aperture seals that

provides two general safety

CPA Protection Aganist CFSI

Counterfeit

– Intentionally manufactured or altered to imitate a legitimate product

without the legal right to do so.

– A counterfeit item is one that has been fabricated in imitation of

something else with purpose to defraud by passing the false copy for

genuine or original or is an items copied without the legal right or

authority to do so.

Fraudulent

– Items that are intentionally misrepresented with intent to deceive.

Fraudulent items include item provided with incorrect identification or

falsified or inadequate certification.

Substandard

– deviating from of a quality lower or scope of qualification than that

prescribed by required standard


27


Suspect items

are items that are suspected of being counterfeit, fraudulent or

substandard

– It may not always be cost effective to verify if a suspect item is indeed

counterfeit, fraudulent or substandard

NOTE: Legally, it may not be appropriate to call an item counterfeit or

fraudulent unless it is verified as such.

– In case of authentication testing, simply obtaining an authentic item or

one that complies with the specification may be the prudent course of

action.

– Conclusive investigation (electrical testing and used advanced

invasive methods) is always time consuming and expensive.


28


Implementation of „CFSI Protection Information System“ – website

platform for data exchange between manufacturer (Kabelovana Kabex),

vendors and equipment end user.

CFSI-PIS ensure exclusion of suspicious item and verification of

genuineness in order to elimination of:

• an unauthorized copy;

• conformance to original OCM design, model, and/or performance

standards;

• production by unauthorized contractors;

• off-specification, defective, or used OCM product sold as "new" or

working; or

• incorrect or falsing markings and/or documentation.

NOTE: OCM – Original Component Manufacture


29

IEEE Initiative – ICAP (IEEE Conformity Assessment Program)

• Conformity Assessment

Activities will Include:

• Conformance to IEEE

Standards,

• Lab audits to maintain

accreditation

• IEEE Certified components

following IEEE ICAP

process.
