APPLICANTS' RESPONSE TO JUNE 15, 1984 BOARD REQUEST FOR ADDITIONAL INFORMATION CONCERNING TDI DIESEL GENERATORS 1.
Introduction The Board has previously requested that Applicants provide information concerning the adequacy of the quality assurance program at Comanche Peak d n relation to the Transamer'ca Delaval, Inc. ("TDI") diesel generators.1 Applicants responded on May 11, 1984 by filing the information requested.2 Subsequent to this response the Board issued a "clarifi-cation" of its information request.
Specifically, the Board stated:
What we are looking for is something in the nature of a table, whici. set [s] forth each specific deficiency in the generators, discusses whether they are design or construction deficiencies, arialyzes what the problem was, and sets forth how it was resolved.
And then, a f ter 1

-e it.
l that's done so that the information available to the' applicants is set forth in a clear fashion,
-we'd like some kind of an analysis as to whether or not, [given] the information [available] to the applicants, some general problem should have risen in their minds, concerning_the [ adequacy]
of the Delaval diesels.
The question is at what point in the history of the Delaval diesels do you reach a point that there are enough indi-vidual questions that you say, we better go to the Delaval plant and find out in more detail whether they are doing things adequately.
- Now, we don't know the answer to that question.
- But, given the history of the Delaval diesels, we want that addressed, in terms of the adequacy record on QA, QC.3 To address this clarification and request for additional information, Applicants provide this further response.
Appli-cants note that the Board has recognized the limitations of the issues to be addressed in this response.
As the Board has stated, with respect to the question of the adequacy of the Comanche Peak diesel generators to assure public health and safety:
Applicants need not address that particular question right now.
It will be addressed only if we find that the design and construction QA oversight
. were inadequate.
If we don't find that they are inadequate, we will trust that particular question to the staff.
We would agree with applicants that it would require us to declare a sua sponte issue for us to go into that matter.*
For the record, Applicants continue to maintain that because this matter was not raised by the Intervenor, the Board should not have initiated, sua sponte, its own inquiry into it.
See 3
Conference call of the Board and Parties, June 15, 1984, Tr.
14,054-55.
4 Id. at 14,056.
" Applicants' Response to January 31, 1984 Board Memorandum Requesting Information Concerning Delaval Diesel Generators," at 9.
Nonetheless, in an effort to expedite the timely conclusion of_this proceeding, Applicants provide additional information to address the two questions from the Board's January 31 Order concerning (1) the adequacy.of Applicants' QA program to detect
~
design or construction problems in TDI diesel generators, and (2) the ' frequency and seriousness of problems with the Comanche Peak diesel generators.
In providing this further response, Applicants interpret the Board's request for information concerning " construction problems" to mean those related to the manufactore of the diesel generators.
'2.
QA Activities Conducted By TUGCO A chronology of audit and inspection activities performed by or on behalf of TUGCO has been assembled and is appended as.
This chronology demonstrates the operation of the TUGCO QA program in the periods prior to award of the contract to TDI, during the manufacture of the diesel generators and auxili-ary systems, assemblies and components, and once the diesel engine, generator, auxiliary systems, assemblies, and components were received on-site at Comanche Peak.
Prior to contract issuance and the placing of the orders for the diesel generators with TDI, a pre-award survey was conducted on behalf of TUGCO by the Architect / Engineer ( A/E), Gibbs and Hill.
This pre-award survey was conducted October 1-3, 1975 and covered compliance with 10 C.F.R. Part 50, Appendix B, and ANSI
Standards N45.2.9, N45.2.11, and N45.2.13 (subsets of N45.2).
Several programmatic deficiencies were found, and TDI made commitments to correct the deficiencies.
Subsequently, on January 26, 1976, in a response to Gibbs and Hill, TDI addressed all deficiencies.
This pre-award activity was followed by an audit conducted by TUGCO on May 11-12, 1976.
This audit addressed compliance of the TDI QA program with 10 C.F.R. Part 50, Appendix B, and ANSI Standard N45.2.
This audit verified the implementation of corrective action on deficiencies identified during the pre-award survey and no new deficiencies were identified.
The purchase order was issued April 8, 1976.
During the period from the purchase order issuance until the Unit 1, Train A5 diesel engine and generator were delivered to the Comanche Peak site on November 11, 1977, TUGCO engaged in six documented inspections.
Prior to shipment of the engine, generator, and associated equipment for the Unit 1, Train A machine, TUGCO conducted a release inspection October 24-27, 1977.
Subsequent to this activity, a release inspection for the major components of Unit 1, Train B was conducted November 29, 1977.
The Unit 1, Train B diesel engine and generator were received on-site December 19, 1977.
The major components (engine and generator) were installed on their foundations (" landed")
September 13, 1978 (Unit 1, Train B) and September 16, 1978 (Unit 5
Each unit has two diesel generators, denoted Train A and Train B.
- o-.
5--
1, Train A).
Ad4'tional Unit 1, Train A and B equipment was-Linspected and released for shipment throughout the period from December, 1977 to July, 1979.
.This process was repeated for the diesel generators for Unit 2.
Performance. tests for the Unit 2, Train A engine were witnessed July 22, 1979.
The Unit 2, Train B_ performance tests were witnessed August 22-25, 1979 and found acceptable.
The Unit 2, Train A engine was released for shipment August 31, 1979 and received on-site September -21,-1979.
This engine was subsequently landed on its foundation September 27, 1979.
The Unit 2, Train B engine release inspection was held Septembe r 17-21, 1979.
The engine for Unit 2, Train B was received on-site on October 9, 1979 and-landed October 10, 1979.
Again, as for Unit 1,
the diesel generator components and -assemblies for the Unit 2 systems were fabricated, tested, inspected, and shipped separately.
Following the inspection, release, shipment, receipt, and installation of the diesel generator major components, other com-ponents continued to be fabricated and shipped.
These components were-subjectea to inspection and testing during the period up until August, 1982, when preparations for preoperational testing were.being made.
The Unit 1 engines were first run in September, 1982.
The Unit 2 engines have not yet been completely assembled and run.
i The chain of events detailed above indicates the time lag that occurred between the time the engines were manufactured and delivered on-site and the time at which testing was initiated.
Numerous OA activities were undertaken by TUGCO during this period.
Because the diesel. generator systems were not yet fully assembled, TUGCO relied upon the TDI QA program and TUGCO witnessing of shop tests of components and assemblies to assure compliance with 10 C.F.R. Part 50, Appendix B.
After the Unit 1 machinen were assembled on-site and preparations for preoperational testing began, deficiencies were noted, which were documented by Nonconformance Reports ("NCRs").
De ficiencies detected during preparation for and conduct of preoperational testing were documented in Test Deficiency Reports ("TDRs").
The deficiencies detected are discussed in the next section.
3.
Analysis of Deficiencies The NCRs, TDRs, vendor 10 C.F. R.
Part 21 reports, and 10 C.F.R. Part 50.55(e) reports have been examined for the Unit 1, Trains A and B diesel generator systems.
The Unit 1 diesel generators were chosen because they have been completely assembled on-site at Comanche Peak and have been run for extended periods.
The Unit 2 machines are not fully assembled and have not yet been run on-site.
Therefore, only the Unit 1 diesel generators provide an accurate picture of the extent and nature of deficiencies encountered in the TDI diesel generators at Comanche Peak.
i The deficiencies are tabulated in Attachment 2.
The table indicates.in which Train the deficiency occurred, provides a brief description of it, categorizes it (design, manufacture,
-installation,' documentation, qualified commercially-procured component,6. shipping, storage, or a combination in cases of uncertainty), provides its significance (high, moderate or low),
provides the date and document in which reported, indicates the detecting organization and time in the procurement and testing process, and the resolution of the deficiency.
There are a. total of 42 deficiencies documented by NCRs.
Of these 42, the deficiencies in 12 were initially reported to TUGCO by TDI using 10 C.F.R. Part 21 reports.
As a result of receiving the 10 C.F.R. Part 21 reports, TUGCO documented the potential deficiencies using NCRs.
Also, of the 42 NCRs, only 17 occurred prior to 1982 (th2 period during which the vast majority of diesel generator assemblies and components were fabricated and shipped to the Comanche Peak site).
At that juncture virtually all of the design, fabrication and installation activities had taken place.
Five NCRs documented in 1984 are included in the list, although these have occurred after the Shoreham crankshaft failure and the formation of the TDI owners' Group.
There were 27 deficiencies documented by TDRs.
All but two of the TDRs occurred in preparation for, or conduct of, the preoperational testing of the Train A and B diesel generators.
6 Some components are commercially procured and qualified as, for instance, many electrical components and systems.
These are normally qualified by actual testing.
. Two occurred during subsequent testing.
The number of TDRs is not very large when it is considered that a very complex piece of equipment was being prepared for service.
The deficiencies can be broadly classified as follows:
(a) turbocharger and governor lube oil systems -- 3: (b) pumps and governor -- 3; (c) brackets, supports and piping -- 12; (d) miscellaneous mechanical items -- 12; (e) electrical wiring, marking and motors -- 20; ( f) instrumentation -- 7; (g) instrument and electrical equipment calibration -- 9; (h) pushrods -- 1; and (i) documentation -- 2.
Although there were several instrument calibration and electrical deficiencies reported, their number and type are not unusual for the complexity of the systems involved, recognizing that the components were not brought together until their assembly at the site.7 None of the above deficiencies was of sufficient significance or repetitive nature to cause concern for the adequacy of the TDI CA program with the exception of the welding on and material selection of the auxiliary skid and its supports.
The Board has already been made aware of this matter.8 As explained in the previous section, the major elonents of 7
See Affidavit of Edward J.
Kreh, Jr.,

-9_
procurement and delivery of the diesel generators for both Units 1 and 2 were completed prior to the initial detection of this particular deficiency. includes a tabulation of the deficiencies detected as a result of TUGCO activities following the crankshaft failure at Shoreham in August, 1983.
These deficiencies are not included in the count above because they occurred after industry had been alerted to potential problems at TDI.
With respect to the findings of the recent disassembly and inspection of the Unit 1 Train A and B' diesel generators, there were several deficien-cies in components which have engendered reservations as to the implementation of the TDI QA program.
However, the nature of the detected deficiencies was such that they would not have been observable by TUGCO without disassembling the engine and in many cases ' would not have been revealed until after a significant number. of hours of operation.
Such disassembly would not normally occur other than during a planned maintenance outage.
Itowever, as with the earlier auxililary skid deficiency, these results became known to TUGCO well after the major elements of
.the design, fabrication and assembly of these machines had been completed.
Based on the examination of deficiencies outlined above, it is apparent that neither the number nor nature of deficiencies (other than the lone case of the deficiencies in the auxiliary skid) was indicative of potential problems in the TDI QA program.
Furthermore, the time sequence between procurement and testing
. ~
. ~. _ _
.was such as to foreclose such a concern being raised any earlier than-July, 1980, well after. delivery of the major components.
As for the deficiencies detected during the test and inspection
' program these were detected as a result of industry reaction to the Shoreham crankshaft faliure in August, 1983, and were not
'known to TUGCO at a time in which' remedial QA action could be taken.
It.should be noted that TUGCO is participating in the TDI Owners' Group effort, which is rigorously addressing and j
resolving deficiencies in the TDI diesel generators.
Further-more, TUGCO has included its QA oversight of TDI.
This has included increased NDE requirements and the witnessing of all required NDE and shop testing of replacement parts and inspection-of individual components.

Summary d'
'In an effort to be fully responsive to the Board's 4
information request, Applicants retained the services of Edward J..Kreh, Jr.,
an expert on vendor QA programs.
Mr. Kreh's affidavit is appended as Attachment 4.
Mr. Kreh examined nonconformance reports, test deficiency reports, TDI 10 CFR Part 21 reports, disassembly _and inspection reports, and other documents.
He discussed the deficiencies contained therein with cognizant TUGCO employees.
Mr. Kreh also examined audit and inspection reports and discussed them with QA personnel.
Based upon this objective assessment, the following has been demonstrated:
a i
T
.m m
1, 3.
1.
TUGCO,'through its A/E Gibbs and Hill, conducted pre-award evaluations of TDIr deficiencies were found; TDI committed to implement a QA program in compliance with 10 C.F.R.
Part-50, Appendix B and proceeded to undertake corrective action.
TUGCO's actions comported with industry practice and were in compliance with 10 C.F.R. Part 50, Appendix B (Kreh Affidavit, pp. 2-3).
2.
TDI was placed on the Approved Vendors List (" AVL"), awarded the contract for the diesel generators, and the order for the diesels was placed with TDI.
TUGCO was justified in placing TDI on the AVL and procuring the diesel generators from TDI based upon their source evaluation of TDI capability in accordance with ANSI Standard N45.2.12 and the vendor's commitments to implement an adequate QA program.
Again, such action by TUGCO comported with 10 C.F.R Part 50, Appendix B.
(Id.)
3.
TUGCO audited the implementation of TDI's OA program over the period from contract award to the shipment of the diesel generator assemblies and components; four audits and approximately 35 inspections were conducted at vendor sites.
Among these activities were the witnessing by TUGCo of shop testing by vendors of components and assemblies.
(Id.,
- p. 3.)
4.
TUGCo relied upon their audit and inspection verification of the adequacy of the TDI QA program for the design and manufacture of the diesel generators; TUGCO witnessed shop
e o
j.
-tests of components and assemblies followed by testing of the fully assembled diesel generators at the plant site.
Such a means of verifying the design and manufacture of the
-machines comports with 10 C.F.R. Part 50, Appendix B and applicable industry standards to which TUGCO has committed.
(Id., pp. 3-4.)
5.
The record of audits and inspections indicates that TUGCO L
took corrective action when the need arose.
This included refusal to release equipment for shipment and communications between TUGCO's management and TDI's management to address L
discrepancies.
(Id., p. 5.)
6.
' During the period front the time the diesel generators were ordered until the major components were received on-site, there were no indications that the TDI QA program was not l
acceptable. (Id.)
This comported with industry experience l
with TDI (Id., pp. 4-5), wherein no najor deficiencies were found and no concerns about the TDI QA Program raised until the occurrence of the cracked crankshaft at Shoreham.
7.
The vast majority of deficiencies were detected only after l
the engines had been received on-site, stored, assembled, l
and preparations were made for preoperational testing.
(Id., p. 6.)
i L
m
- --. =.
. s 8.,
With the. exception of the auxiliary skid and support deficiencies, _ the deficiencies detected during the period prior to preoperational testing and during preoperational testing did not indicate a breakdown in-TDI QA.
(Id., p.
5.)
9.
The types and quantity of deficiencies (other than-the auxiliary ekid) were minor and lacked-the significance and repetitive nature to suggest that there was a QA breakdown at TDI.
(Id., pp. 5-6.)
10.
The deficiencies discovered during the disassembly and inspection of the Unit 1 diesels suggest that the TDI QA program may have been inadequate (Id. p.6).
This was widely recognized by industry in the formation of the TDI Owners' Group.
5.
Conclusion From the foregoing, the Board should conclude that at all pertinent times during the design, fabrication and delivery of the major elements of the diesel generators, there was no indication that the TDI QA program was inadequate.
With the exception of the auxiliary skids, the frequency and seriousness of the deficiencies were not sufficient to have warranted a determination that TDI's QA program was inadequate.9 The types of deficiencies detected during the preparation for and conduct 9
It should be noted that TUGCO spent considerable time and resources in resolving the deficiencies in the auniliary skids.

n of preoperational testing were minor and of the kind to be expected.
These deficiencies were not sufficiently numerous to cause concern that the TDI QA program was inadequate.
With respect to the auxiliary skid deficiencies and the deficiencies detected during the disassembly and inspection of the Unit 1 diesels, the major components of the diesel generators had been manufactured and delivered well in advance of TUGCO becoming aware of these deficiencies.
