GUIDE TO IEC/IEEE COOPERATION

When we wanted to start the work to harmonise IEC 60780 and IEEE 323 in 2006 we didn’t have the proper tool for this

In 2008 we did receive the first documents supporting dual logo standards development

In late 2018 the different document was merged into one document

It’s not totally up to date

IEEE 387 AS DUAL LOGO?IEEE STANDARD FOR CRITERIA FOR DIESEL GENERATOR UNITS

APPLIED AS STANDBY POWER SUPPLIES FOR NUCLEAR POWER

GENERATING STATIONS IEEE/NPEC have contact IEC SC45 WGA11 for a possible

cooperation

There will be more possibilities for cooperation onthe power area in the future

Convener of WGA11 is Sofia Johansson, Ringhals NPP

16


NRC INTEREST FOR IEC/IEEE AND IEC STANDARDS

17

NRC will (quite soon?) endorse IEC/IEEE 60780-323 when revising RG 1.87

They are also locking at the possibility to endorse IEC standards where there already exist a IEEE standard!


The first time that we where able to transform two existing standards to one dual logo

Breaking new ground

18


IEC/IEEE 60780-323 A process that took 10 years!

Different history:Class 1E equipment and Equipment important to safety

Base is British English (ageing – aging)

IAEA Safety Glossary

Small changes in wording

The minimum 100 hours for ageing have been taken away

Focus on achieving a dual logo, not develop the technical demands

19


IEC/IEEE 62582

20


IEEE

21

• IEEE Std 323-2003 establish the use of Qualified Condition

• Do we have the proper tools for this?


IAEA Between 1990 and 2000 IAEA did some

extensive work regarding management of ageing

TECDOC 1188 describe ways to work with different types of cables

They point out different ways to measure degradation in different cable insulations material

22


IAEA In Volume II of 1188 there is the result of a

Round-Robin test on cable samples.

15 different test laboratories did measurements on unaged and aged cable samples

Methods used was: Tensile test, Indenter, OIT, OITP and TGA

23


CONCLUSIONS FROM THE IAEA WORK “The main conclusion that has come out of this series of round-robin test has

been the need for more detailed specification of the test procedures for condition monitoring methods. This includes the information which needs to be reported with any data generated from such test.”

The variation of result between different laboratories and lack of information in the test reports is to big.It´s not possible to use measurement from different laboratories to handle a EQ system based on Qualified Condition

24


THE START OF IEC/IEEE 62582 WORKING GROUP

Discussions started between technical experts in IEC and IEEE

New agreement between IEC and IEEE (AC/22/2008) in July 2008 makes it possible for IEC and IEEE to develop new standards in joint IEC-IEEE projects on either party’s initiative

CONDITION-BASED QUALIFICATION

Qualification based on measurement of one or more condition indicators of equipment, its components, or materials for which an acceptance criterion can be correlated to the equipment’s ability to function as specified during an applicable design basis event

[SOURCE: IEEE Standards Dictionary Online]

28


CONDITION INDICATOR

Characteristic of equipment or its components that can be observed, measured and trended to infer or directly indicate the current and future ability of equipment to function within acceptance criteria in all specified service conditions (including DBE conditions)

29


USE OF QUALIFIED CONDITION

30

A condition indicator is monitored during and (especially) at the end of the artificial ageing before DBE testing. The condition at the end of the ageing is the qualified condition.


STATUS OF IEC/IEEE 62582 TODAY

31


Less than three years from project start final standard

Stability date 2021

We have started the work with revision.PAR in IEEE,RR in IEC

32


NEW REVISION OF PART 1 Reference to IEC/IEEE 60780-323

Information that we hoped to have in IEC/IEEE 60780-323 was not included. Something to include?

Adapt to the demands in IEC/IEEE 60780-323

More explanations and demands about acceleration factor in accelerated thermal ageing. A new annex about DLO

Include something about visual/tactile inspection. Additional information in an new annex

An new annex about process to implementing qualified condition.

A CD1 during this summer33


Stability date 2021


A CD1 during this summer

34


NEW REVISION OF PART 2 We will not include

recovery time need more experience

The influence of the clamping force will be addressed

35


Stability date 2022

IEEE will write a PAR for revision and IEC a RR

Start the actual work during 2020

No big need for modification have been identified?

36


Stability date 2021


A CD1 during this summer

37


NEW REVISION OF PART 4 Specify specimen preparation in a more detailed

way Lower the requirement of test specimen from 10

to 5 mg Specify the set temperature for different material

38


• Methods for monitoring the attenuation condition on optical fibre

• Stability date 2025

• No need for revision for time being


PART 6 INSULATION RESISTANCE DURING DBE TEST Test labs use the same measurement technics during LOCA

test as during normal condition

Instrument that are designed to measure TΩ are not suitable for measure values in the range of 10-100 kΩ

Test labs usually miss the lowest IR value due to not having continuous measurements.

Proper grounding of the test object is not defined.

40


PART 6 INSULATION RESISTANCE DURING DBE TESTStatus today

FDIS IEC/IEEE 62582-6 circulated within IEC. Last day to respond May 25

IEEE will soon start the recirculation Ballot

41


TO WORK TOGETHER, IEC AND IEEE

Its wise to work together. We have a limited amount of technical experts and to divide recourses isn't wise in a industry under economical pressure.

From a technical point of view we have had a very good cooperation.

From a formal perspective there are problems. To handle the bureaucracy from both IEC and IEEE at the same time is a challenge, however, person-to-person discussions are the ideal solution to managing such challenges.

Some individuals have been reluctant to support the work but I rarely meet any conflicting interests now.

42


IAEA TECDOC 1825 Newly published

on IAEA webpage

New round-robin test was performed

IEC/IEEE 62582-x was used

43


EAB, IM,OIT and OITP have been standardized in the 62582 series

The result is green

Could we improve the other test methods?

44


WOULD YOU LIKE TO HELP? How to improve existing parts of 62582?

A new area to standardizes under the 62582 series?

Membership in IEEE or IEC gives the possibility to be a full member of the working-group.

The working-group has the possibility to invite technical experts for a specific task.

Contact me with suggestions an questions.

45


STANDARDIZATION A GOOD BASE FOR KNOWLEDGE

Don’t be afraid to participate

Convince your manager that it is a good way to gain knowledge

Its OK to start with gaining knowledge

Sometime in the future you will be able to give back something of what you have gained in the beginning

A great way to expand your network (in parallel with EQ-meetings)
