r FINAL REPORT REVISION 2 - DER 81-22 DEFICIENCY EVALUATION 50.55(e)

ARIZONA PUBLIC SERVICE COMPANY (APS)

PVNGS UNITS 1, 2 & 3

1. Description of Deficiency The following Class IE equipment is impacted by defects existing in AGASTAT relays manufactured by Control Products Division, Amerace Corporation:

4.16KV Switchgear AC Panels Load Centers DC Load Centers Motor Control Centers Aux. Relay Cabinets a.

Control Products Division, Amerace Corporation notified Bechtel Power Corporation that the AGASTA't 7000 Series date coded 7740 through 7840 (1977 40th week through 1978 40th week) had diaphragm contamination on a small percentage of the total production due to use of unfil-tered shop air at one of the blow off stations which was used only for peak manufacturing periods. Compressor lubricant, a silicon contaminant, on the diaphragm coupler causes the diaphragm to leak resulting in a premature time-out :ondition.

Amerace Corporation by reference (g) has indicated that a contami-nated coupler which has sat unused for a long period of time will exhibit the following traits when functioned on a bench test.

• The initial time delay would be lower than the set time delay.

• The next time delay would be significantly shorter than the first.

• The third time delay would be significantly shorter' than the second.

b.

On February 2, 1982, the Control Products Division, Amerace Corporation informed the U.S. Nuclear Regulatory Commission that approximately 20 percent of their AGASTAT E-7000 Series time-delay relays manufactured during the period between July 15, 1981 to January 12, 1982 may not operate properly.

Quality Assurance tests performed to ascertain acceptable performance over extended time periods have determined that the pneumatic timing diaphragm manufactured by one of two diaphragm suppliers exhibited a bleed-out of a fluid substance as a function of time and temperature.

This substance may affect the diaphragm seal on the relays operated at high temperatures for extended periods, resulting in shorter time delays than those set on the relay dial. Although the temperature required to initiate significant bleed-out would not be encountered in the majority of these relay applications, it is within the range j

of nuclear safety qualification tests required by IEEE-323 and IEEE-344.

r-z FINAL REPORT REVISION 2 - DER 81-22 Page Two In s letter dated February 2, 1982, the Control Products Division of Anerace Corporation requested users to return all of the discussed relays for inspection and possible replacements.

c.

On May 30, 1960, General Electric, Electric Ut.ility Sales Division, informed Bechtel Power Corporation that Control Products Division of Amerace corporation requested return of selected AGASTAT 7000 Series and E-7000 Series time delay relays installed in GE motor control centers as identified by Reference (d). Amerace Corporation had identified a " staked sub-assembly which exhibits looseness after several hundred thousand operations at a rapid cycle rate," and as a precaution requesed these be returned for possible repair or replacement.

II. Analysis of Safety Implication Conditions (a) and (b) have separately been evaluated as reportable under both 10CFR50.55(e) and 10CFR Part 21.

Condition (c) is evaluated as not reportable, as documented by the Amerace Corporation testing results given in Reference (i).

This report summarizes all conditions requiring replace ment AGASTAT relays for overall project control purposes, since there is overlap of impacted equipment.

If left uncorrected, conditions (a) and (b) could possibly preclude safety related equipment from performing per design intent.

III. Corrective Action a.

As listed on the Attachment, the 7000 Series AGASTAT relays will be tested and replaced as required during normal start-up activities.

All Class IE installations found defective will be replaced with qualified relays. Nonconformance reports have been initiated to document removal, testing, and replacement, as applicable.

b.

As indicated by the 10CFR Part 21 notification and IE Information Notice No. 82-04, the applicable electrical panels will be inspected for existence of the E-7000 Series relay. All E-7000 Series AGASTAT relays manufactured between 7/15/81 and 1/12/82 will be returned to the manufacturer for inspection and possible replacement. Non-conformance reports will be initiated as applicable to document removal and reinstallation of these relays.

The relays identified by Reference (d) will be removed from the GE c.

motor control centers and returned to GE as requested. Nonconfor-mance reports will be initiated as required to document removal and reinstallation of these relays.

Description of Circumstances:

On February 2, 1982, the Control product Division. Amerace Corporation informed 4

the U.S. Nuclear Regulatory Commission that approximately 20 percent of their AGASTAT E-7000 Series time-delay relays manufactured during the period between July 15, 1981 to January 12, 1982 may not operate properly.

1 l

Quality Assurance tests performed to ascertain acceptable performance over ex-tended time periods have determined that the pneumatic timing diaphragm manu-factured by one of two diaphragm suppliers exhibited a bleed-out of a fluid substance as a function of time and temperature. This substance may affect the diaphragm seal on the relays operated at high temperatures for extended periods, resulting in shorter time delays than those set on the relay dial. Although the l

temperature required to initiate significant bleed-out would not be encountered

)

in the majority of these relay applications, it is within the range of nuclear

]

safety qualification tests required by IEEE-323 and IEEE-344.

In a letter dated February 2, 1982, the Control Products Division of Amerace Corporation requested users to return all of the discussed relays for inspection and possible replacements. Copies of the letter and a list of the users are 1

enclosed.The Control Products Division r:: cords do not identify individual nuclear power plants because most shipments were mht'e to nuclear steam supply 4

i system (NSSS) suppliers, vendors, panel manufacturers, arcilitects and engineers and utilities.

j This infomation notice is provided as an early notification of a potentially significant matter.

It is expected that recipients will review the infor-j mation for possible applicability to their facilities and take appropriate action as necessary. No specific action or response is required at this time.

(1) Report on Premature Timeout Problem on 7000 Series Agastat Time Delay Relays Gentlemen:

In Paragraph 4 of your -letter you asked that we review our responsibility for providing the information required in 10CFR50 Se c tion 21. 21(b )( 3 )(VI ).

We feel that there is no responsibility on our part to pro.-

vide this information, because the product which you have purchased is our standard commercial grade time delay relay, sold through many channels of distribution.

In April, 1979 Control Products Divi-sion placed on the market our E7000 series, which conforms to 10CTR50, and is manufactured 'inder that quality program, which also includes 10CTR21 covering traceability.

Those products are sold only on a direct beJis, and are identified with our 7000 series having the pre-fix letter "E"

and suffix "001" (Example E7012AD001).

In summary, the units that you have in questions were not subject to any NRC regulations at the time they were purchased.

Reference the Paragraph entitled " Background" We feel that the explanation and description of the problem is not correct, and that it would be advantageous for us to give you Control Product's correct background, as related to the problem.

This is as follows:

E In the latter'part of 1978, we received a few units back from the field that exhibited premature time-out.

Upon investigation it wi

.. e disphref=

(relay diaphrago does not crack) which caused the diaphrages to 1eek resulting in pre =ature time-out.

The contaminant was found to be silicon, which in turn was traced to an. unfiltered air line used to blow off parts.

Compressor lubricant in the air line was the source of the silicon.

Fortunately this particular blow-off station was used only.

during peak manufacturing periods.

The overall number of units pass-ing through this station was small in relation to totn1 uni ts prod'uced,'

olthough in a given batch of parts conta=ination could appear on a high percentage in that batch.

The following corrective action was taken:

1 - The written manuf acturing instructions have been re_yised to call out " Filtered Air Only" for blow-off operations.

2 - An ultra-sonic cleaning operation has been added to the manufactur-ing procedure.

3 - A visual. inspection has been added to check for the presence of contaminants.

The period during which " suspect" units were produced was 1,

October 1077 to 1, October 1978.

We use the word " suspect" in the totalunitsproducedduringthisperiodwer([h cense that very few of the contaminated.

contaminated coupler and has sat unused for a If a unit has a long period of time (which would be the case for any units appearing now ) it would exhibit the following traits:

The initial time delay would be lower than the set time delay.

The next time delay would be significantly shorter than the first.

The third time delay would be significantly shorter than the second.

p C#

If a unit operates satisf actorily for several operation, it does not have a contaminated coupler.

Control Products recommends the use of our "E"

series ti m e r's 3

and relays when application calls for Class 1E certification.

SUBJECT:

Recall of Model E7000 Relays As a result of your letter of February 2,1982, we have identified Nuclear IE (Class Q) orders on which your subject device may have been shipped.

Enclosed is a listing of these orders and contact addresses to reach our customers who may have these relays. You should coordinate directly with these sites, as General Electric will not bear any expense as a result of this recall. A courtesy copy of this letter has been mailed to each.

Only IE (Class Q) requisitions were Identified as traceability records are not maintained on non-1E equipment (Class R). Eight relays on purchase orders A683M671230, 675148, 751216, and 768T80 are Class R.

It is highly likely these are also at Palo Verde. These could have been shipped on purchase order 10407-13-EM-18 item 157A (2) and purchase order F-134994 (3) - Arizona Public Service Company purchase order. Two relays were still in our shop. They were returned and have been re-received at Nebane. They are model E7022AF, Ser. 81260380, on purchase order A683M659142, and model E7012AC, Ser. 81373342, on purchase order A683M719175. The balance have been shipped to customers in equipment or as/ parts and should be in the equipment listed.

Enclosed is a copy of your listing so noted.

Request you advise the undersigned when all relays have been returned and dispositioned.

Mr. Mike Torikdan Demar Mr. Torikgsmn:

On Merch 20 1980 we notifie.d General Electrio.

Mebano North Curolfnm. of a pomoible problem with a sub--

m ai ss embly in our 7000 scrime nuclear safety related relaye.

Thi a. problem was noticed durina our continuing ear tended pe r f o rm anic e tent program.

In a rapid eyol ar test, a core stop to p1mte stakin operation c amme loose after a few hundred thous.and loose [se c e m.

When the staking brenha ckot of noima, but still functions.

the relays make a T

worse case would be a continuously energized relay.

Theme might draw hi gh er r than normal current and eventually over-heat.

Most of the worst staking was eeught be' fore shipment, however some m aarginal assemblies may have gotten to the o

field.

Although the rapid cycle test is more severe than normal usag.a and the qualified life of nuclear series 1m 23 c y c L aa s, we r ee c oruu ande d that customer purchasin

" nu. 0 00 olear eenf e ty related" relays return them Zor core / late replercoment,== a pre cau tionary measure.

Of the 77 nuo ear r e lay as involved all but the 24, which G.E.

amys were sent to you, bavo been returned.

Since wo did not experience the failures in the type of t e ma ti n g done for nuclear qualification it was decided that NHC notification van not required.

• f"hi s, judgement is now eau ppo r t e d by tho fact that since this potentini problem w e. n discovered in 1980 there have been no reports or field f ami lu rer s f rota this cause in either nuolerar or conventional product in es t all na tion s.
