5. PNPP has incorporated all of the applicable recommen-da'tions of each of the Phase I reports into its TDI engine pro-gram. For example,; connecting rod bearing shells on the PNPP engines were inspected by the use of radiography, eddy current and liqui-d penetrant examination as well as by visual checks.

Some-bearing shells were replaced so that all shells presently installed.in the. engines meet the acceptance criteria estab-lished by the Owners Group. Likewise, the engines' fuel oil injection tubing was examined by eddy current testing for fab-

~

- rication flaws.similar to those found at Grand Gulf. No such flaws were discovered on the PNPP fuel lines. As an additional precaution, PNPP-will install shroud lines around=the tubing.

A summary-of the results of t'ehPNPP inspections performed-on

'the: Phase I items is contained in the "PNPP TDI Diesel Genera-

~

tor Program Plan" submitted to the NRC on January 17, 1985.

6. .CEI also employed an independent engineering con-sulting firm, Southwest Research' Institute ("SwRI") to review,

evaluate, and independently verify the. methodology; employed, results, and conclusions:of each of the Phase I studies.

SwRI,'s.overall conclusion, with regard to the Phase I1 effort, 4

s

~

was'that the Owners Group' reports were accurate in their evalu-ation of the potentially. generic. problems. See. Affidavit of LCharles D. Wood III.

9; . Component Revalidation Checklists ("CRCs") were pre-

-pared for each'of the. Phase II components designated for quali-

~

,tyLrevalidation at PNPP. These checklists formed the basis for the field inspections which were then conducted during the en-

gine revalidation effort. For example, the valve spring and retainers. required a quality revalidation inspection. The Own-ers Group had identified a certain color-coded spring as being unacceptable. All springs on the Unit 1 engines were, there-fore, visually inspected to verify the color coding. All

~ springs on the two. engines were found to be acceptable. Re-

-sults of the inspection were recorded on a Quality Assurance Checklist ("QAC"). In addition to the springs, the flexible:

and overspeed trip couplings were~also quality revalidated.

~

The component's CRC required a visual examination of the cou-plings for. signs of wear,-deterioration, or any other discon-tinuities. The. field inspection found;the couplings to be in new condition. Results were also documented on a.QAC.

L10. - In or(erlto perform the required QR inspections on the PNPP' engines, a task force was establishedEconsisting of

_ project personnel from PNPP organizations such as':

(a). : Nuclear Construction Engineering 1Section,

~(b) . Nuclear Test-Section,

[( . (c) PerryiPlant Technical Department,

~

e (d) . Perry Plant Operation Department, and-y 9

l

• s

(e) Nuclear Quality Assurance.

sThis task force was-responsible for coordinating and imple-menting the disassembly, inspection, procurement of parts (as necessary) and reassembly of the TDI diesel engines. To expe-ditiously resolve day-to-day questions aris'ing'during the testing and revalidation effort, key task force members and technical support staff were' moved to a single work area. Ap-

. proximately forty individuals have been assigned full. time to support this' activity. Since early September, 1984, a meeting has been' held each day to discuss progress and plan the next

-day's work-effort. Each of these key task force members is ex-oclusively assigned to the diesel generator testing and revalidation effort and will remain so until all testing is ,

completed.

l'1. .The revalidation (tear-down,. inspection and-reassembly) of the Unit I PNPP TDI diesel engines was performed

~

in accordance with INPP's Quality Control Program. See 1 21.

' Procurement of parts to support the revalidation effort was Jalso conducted in accordance with specified quality assurance.

-standards as. discussed at 1 20.

C. The Engine Revalidation Effort, Testing and Inspection-

~

12. .While the~ engines were disassembled,Lroutine inspec-

~

-tion'and maintenance were also performed in accordance with

~

PNPP' site-specific procedures and the manufacturer's-instruc-

-tions. ' Changes l recommended by TDI for the PNPP engines:in its s

Service Information Memos ("SIMs") were incorporated at this time. For: example, connecting rod bolt washers located between a

the: connecting rod: bolt head and the master rod's face were re-ported.to gall,.via an SIM. The problem washer was replaced with a harder washer, as specified by TDI in its SIM.

13. All unfavorable inspection results were evaluated ac-cording to established.PNPP' procedures, and, in some cases, by the Owners Group. Non-Conformance Reports documenting

' hardware-related problems and Action Requests, documenting pro-grammatic concerns, were written up and resolved in t each case.

14.- Only two notable concerns'were encountered during

,this-revalidation' effort. During the inspection it was discov-

ered.that f'our rocker arms on the Division I engine and'eight

/

rocker-arms'on.the Division II engine had come in. contact with

'.the swivel pad,. indenting the rocker arm forging. The -in' den--

tion,,or lip', restricted the movement'of the. hydraulic lifters.

lit.-appears that the' problem occurred during the factory-run

-tests;and was1 caused by improper adjustment of the lifter.ad-justing screw. :Thefrocker arms-have been restored toLoperating

condition following procedures recommended.by the Owners Group and TDI.

15. .The;second concern'was detected when eddy; current

inspection of-.the oil holesfon the crankshaft by an Owners Groupiconsultant ihdicatedfexcessive machining marks'in1the l' ? %_

i

. unpolished surface at'a. depth greater than 1 inch. All crank-shaft oil holes.were polished to a depth of 3 inches. The eddy current test was repeated on the polished oil holes. The test indicated that the oil holes were free of defects.

D. Engine Maintenance

16. PNPP is implementihg all applicable Owners Group rec-ommendations resulting from Phase I and Phase II of the Owners Group Program. The Owners Group recommendations, when per-

. formed during the revalidation inspections, were listed on g ~CRCs. -If the Owners Group reccmmended ongoing maintenance for a component, this_ requirement was listed in the PNPP Mainte-nance Matrix. Both the CRCs and the Maintenance Matrix are part of.the PNPP DR/QR Report. The SwRI recommendations will valso be incorporated into the PNPP preventative maintenance

. program, as noted below.

17. Maintenance recommendations listed in the PHPP Main-

~tenance Matrix, as well as'SwRI's recommendations,1will be logged'on PNPP's' computer-based preventative maintenance pro-gram-(the " Repetitive Task System"). As'the required main-

'tenance period approaches,_the. computer will. generate a work.

, ; card describing the task and schedule for completion. The maintenance. work will_then be-performed by~the appropriate site-personnel.

V. PNPP DEVIATION ANALYSIS REPORTS

' ;2 5 . Nonconformance Reports'at PNPP are-written for any

type of equipment hardware deviations, including those as minor as; paint scratches or typographical errors on nameplates. All HP

NPP Non-Conformance Reports written against TDI equipment have-been reviewed for reportability to the NRC. Where it was de-

.termined that aLcondition'was possibly reportable, a Deviation.

Analysis Report ("DAR") was prepared. The DAR was then evalu-ated by,PNPP Engineering and Quality Assurance for re-

~

portability to the NRC. Where the condition was determined to

. be'significant, it was reported per establish'ed PNPP proce--

r 'dures.

26. To date,.28 DARs have been. written with respect to the TDIzdiesels.1/ 22 of these DARs have.been reported to the

-. NRC as significant pursuant to 10 C.F.R. Part.21 and/or 10 C.F.R. Part,50.55(e). Of those: reported, 19. involved equip-ment supplied or designed by TDI. The three remaining DARs

I' VI. OVERALL CONCLUSION

27. The PNPP TDI diesel generators have been thoroughly reviewed from both a design and quality standpoint by the TDI Diesel Generator Owners Group and PNPP's engineering and quali-

.tycassurance personnel. Based on recommendations generated in Phase'I.of the-Owners Group Program, the components with p'oten-tially generic-problems were reviewed, inspected, replaced, and/or modified. All of the Owners Group recommendations are

being. implemented and will be completed prior to fuel load.

-Those' offered by SwRI are being logged onto PNPP's preventative maintenance program and will also be implemented.

L28. The Phase II DR/QR effort,'and'the.thirdLelement of-

'the Own' era, Group effort, which. includes implementation of:a e maintenance. program.and. additional engine testing and inspec-tion of components, provides additional assurance that-the-PNPP' TDI diesel generators will reliably-perform:their~ intended

sdfety-related functions for the life of .the plant'. PNPP is
