INTRODUCTION
~
On July 11, 1979, the NRC issued IE Bulletin No. 79-15 informing all li~ensees that Corr.mon~1ea 1th Edison Company had i der1t ified manufacturir19 defi ciencie.s in higt* pessure core spreiy, low p.ressure core spray, and residual ht-at ren1oval pumps rr.ar.ufactured by Ingersoll-Rand {I-R) Corrpar,y, Cameron Purr.p Div'ision.
The bu1le:tir1 asked licensees to deterrriin~ if pun:ps of similar constructior1 were used ill their facilities, and, if so, whether the same deficiencies could exist~
In NUREG/CH-3049: "Clostout of IE Bulletin 79-15: Deep Draft Pump DeficiE?r1cies, 11 the NRC staff arrd its tor.tractor sumn;ar*izt:o*d the industry effort and closed out the i~~IH:: \\'lith the exceptior: of following facilities and types of pun:ps:
- 1. Beaver Valley Unit 1:
Two Johnston auxiliary riv~r \\'later pumps.
- 2. Indian Poir1t Units 2 arid 3:
Two I-R contairnrrer1t recirctJlation pumps ir1 each plant.
- 3. Maine Yankee: Three Byron-Jackson contair1ment spray putr.ps.
- 4. NinE; Mile Point Uriit 1:
Four Worthington core spray and two Worthington emergency service water pumps.
- 5. Oyster Creek Unit 1:
Four Byron-Jackson emergency service water pumps and two Layne-Bowler diesel driven fire prcitection pumps.
- 6. Thr~t Mile Island Unit 1:
Fourteen Peerless pumps used for river w~ter and fire protection purposes.
- 7. Hatch Unit 2:
Two I-R core spray pumps.
- 8. Big Rock Point:
Two Worthington pumps used for fire protection purposes.
- 9. Palisadt:S:
Three Worthirigtor1 pumps used for fire protectior1 purposes.
DISCUSSION Based on the staff's review of related NRC inspection reports, the issue was*
closed for Beaver Valley Unit 1, Oyster Creek Unit 1, arid Hatch Unit 2.
For the remaining facilities listed above, the staff r~quEsted additiorial information needed to con;plete its review.
The required additicno. l information requested from the above n1entiotred facilities included the following:
- 1. Tht' type and applhatior1 of the pumps iri question.
- 2.
Drawings, sectional assemblies and parts list cf the puIDps it1 question.

The n,ar.ufacturing deficiencies ider1tified by IE Bulletiri 79-15 can be summarized into three areas: assembly error, out of specification clearance, and damaged parts.
Althoug~ all three deficiencies will eventually cause degradation in pump performarice, degradatior1 sufficient to influence pump performar1ce n-.ight net be detected e:arly iri the servicE life of the pump.
NUREG/CR-3049 proposed a long running time (48 to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />) on a selected sample pump in each plarrt to determine whether deficiencies of the types idt:=r1tified in Bulletin 79-15 existed ir1 those pumps.
However, because no two purr:ps are* idntic:e:l, these sample rurrs might ne;t identify deficiencies ir, ell pumps.
The n~thod proposed ir1 NUREG/CR-3049 might detect sorne deficiencies eo.rly.
Iri scnif cases, these rur1s can orily be performt::d in mini-flo\\'i conditions ir;hictr rnight caust: mort> c!an;age t.(; tht-pun:ps otht-r than that arhirig fron, potential deficiencies.
Review of the subn1itted inforrnaticn leads the staff to conclude that periodic ~urveillarces, such as those required by inservice test irig or techriica l spe-c ifi cation surVE*i 1 lar.ce requ ir~nients, pnJV ide the n:ost t:ffective rneans tc dete:-ct the Bulletin 79-15 deficiericies.

Fer tht: follv\\drg facilities, the licerisees have taker1 the torrective: actiorrs dlscribed below tb ensure that the deficiencies ider1tified in Eulletir. 79-15 do not adversely impact the pumps ir1 their facilities.
- 1.
Indian Point Uriit 2:
The two containment recirculation I-R pumps are tested regularly in accordance tJith the ASME Section XI iriservice t.estir1g requiren:er.t.s.
Test results collected from 1981 to 1989 show no sign of.
performarict degrac!atior1.
Mairrter;ance records since 1974 indicate both pumps needed littlE maintenance.
On the basis of these results, the staff has cor1cluded that the two I-R pumps are flOt adversely affected by the Bulletin 79-15 defi~iericies. The issue is resolved for Indian Point Uriit 2.
- 2.
Indiarr Point Unit 3:
The two contairrmer;t recirculation I-R pumps are tested regularly in accordance with the ASME Section XI inservice testing requirements.
t~eifottr:ar1ce records indicate that one of these pun:ps was r~built extensively after it failed one of these tests. Other test results tcllected from 1978 to 1989 show no sigr1 of performance degrac!atior1.
Ori the basis of these results, the staff has concluded that the two I-R pumps ar~ rro lor;ger adversely affcted by the Bulletin 79-15 deficier1cies.
The issu~ is r~solved for Indian Point Unit 3.
- 3.
Maine Yar1kel::
The three Byron-Jackson pun:ps Wl::'re periodically surveillaricE tested in Bccordar1c~ with the ASME S~cticn XI inservice t~sting requirements.
Test datD tclle-cted between 1984 and 1989 iridicote rio performance

On the basis of these results, the staff concluded that the Bulletin 79-15 deficiencies do not adversely impact these pun~s. ThE issue is resolved fer Maine Yankee.
- 4.
Nine. Mile Point Unit 1: The six Worthir1gton pumps were tested regularly in accordance with the ASME Sectior1 XI ir1service testing requirements.
Mair.terianc.r:* records show that two core spray pumps, 111 (05-1985, 03-1986),
and 112 (05-85, 08-85, 03-87) were rebuilt several times~ The surveillance requirements were able to detect the deficiencies en a timely basis. Recent test results show no sign of performance deterioration. The staff has cor1cluded that the Bulletin 79-15 deficiencies have been adequately addressed fer these pun1ps.
This issue is resolved for Nine Mile Point Unit 1.
- 5.
Three Mile Island Unit 1: The issue was closed out in NRC inspection Repc:rt 80-29.
However, due to son'e 11 1isccrmtmicatfor1, it was erroneously reopened~in NUREG/CR-3049.
A recent discussion determined that all 14 Peerh:ss pumps were tested regularly, and a typical surveillar!ce example of three nuclear S*rvice. rivE'r ~iater pumps \\'1ere examined by the NRC staff.
RHer.t tc~t rt*sults show r10 ir.dicatfor1 of performancr= degradation ir: any of these pumps.
On the basis of these results, the staff concluded that.
t.h* Bulletin 79-15 deficit:!r1c.ies do riot adversely impact thest pu11.ps.
The* issue is resolved for ThrEE Mi1e Is land Urdt 1.
- 6.
Big Rock Poirit:
Techr.;ca*l specificatior1 surveillar.ce requirements require periodic testirig or. these t\\r~o fire service pumps to verify their operability.
Test data collected from the past fivt.: years show no sigr.s of performance d~gradation. On the basis of these results, the staff concludes that the Bulletir1 79-15 deficier1cies do not adversely impact tht:!se pu11:ps.
The issue is rEsolved for Big Rock Point.
- 7.
Palisades: Sirrce the thrt-e: fire protectior1 pt;nps do riot fall within the scope of A.SME Sectior1 XI insE::*rvice testing requiren1ents, their operability was verifi~d by techniceil specification surveilla~ce requirements.
P~:sults fror.: the past fiVE: years show no r;oticeable degradation in perforrnHce.
On the basis of tt:ese results, the staff cor1c.:lucied that the Bulletin 79-15 c!eficier1cies do not adversely impact these pumps.
The issue is resolvtd for Palisades.
CONCLUSION W**-*
One of thti mon* in1port.ar1t functions for surveillar.ce testirig is to detect deficie~cies early, so that proper corrective action can be taken before a component becomes inoperable.
Periodic surveillance is especially eff~ctive when a slo~' deteriorating precess is taking place.
For the types of deficiencies idtr.tifit:-C: by Bulletin 79-15, all affected pun1ps have bHr. tested niany times siric~ tht: issue was ider1tified.
Some pumps were found with deficiencies requiring extensive repairs of the pun1ps.
Mairiteriance ncords indicate that oll id~r1tified deficiencies were adequately corrected. Other purr:ps have ur1dergone periodic surveillar;ces with no detri111er;tal effects beirrg identified *.

B~cause pu~p surveillance is a continuous requirement that applies to all affected pun:ps, the staff btlieves that the types of deficit-ncies identified *;n Bulletin 79-15 which* could result in potential pump failures have been heretofore detected. Therefore, the staff concludes that an adequate basis exists to resolve the safety concerns identified in Bulletin 79-15 and thusBulletin 79-15 is considered closed.
