- 1. Provide a concise description of the present scope, purpose, and objectives of the Design Adequacy Program (DAP) and the Quality of Construction and QA/QC Adequacy Program (Q0C).
Response
Refer to Revision 4 of the CPRT Program Plan (to be submitted under separate letter, TXX-6540) for additional detail.
The purpose, scope, and objectives of the CPRT Q0C Program have not changed significantly from those stated in Rev. 3 of the CPRT Program Plan. As delineated in Rev. 4 of the Program Plan, the TV Electric decision to move directly to a full-scope corrective action progrum ha. obviated the need for certain DAP activities designed to determine the boundt of necessary corrective actions. The DAP methodology has been modif ed to account for those CAP activities.
Reauest:
- 2. Provide a concise description of the scope, purpose, and objectives of the Correction Action Programs (CAPS), the Design Basis Consolidation Program (DBCP), and any other major ongoing programs necessary for the licensing of Comanche Peak.
=! Response:
The purpose of the CAP is: I
- a. To demonstrate that the design of systems, structures and components complies with licensing commitments.
- b. To demonstrate that existing systems, structures and components are in compliance with design; ot To develop modifications which will bring systems, structures and components into compliance with design.
- c. To develop procedures, an organizational plan, and documentation, i.e.,
configuration management, to maintain compliance with licensing commitments throughout the life of the Comanche Peak Steam Electric Station.
The scope of the CAP is:
To validate 100% of the safety-related portions of the CPSES design with the following exceptions:
NSSS Hardware (NSSS interface is reviewed)
Equipment Supplier Design (Design interface is reviewed)
Attachment to TXX-6500-June 25, 1987.-
Page'2 of 24 The objectives of the CAP are:
a.' To produce-a censistent and validated set of CPSES design documentation.
- b. To resolve all design issues identified by CPRT (including those by i external sources) and all design issues _ identified during the conduct of the CAP,-including the identification and implementation of corrective and preventative actions. i
- c. To produce.an upgraded set of design control' procedures.
- d. . To evaluate systems, structures and components ~and perform corrective actions recommended or concurred with by the CPRT.or determined by CAP investigations to be required to demonstrate that systems, structures.and l components meet the design. j The Design Basis Consolidation Program (DBCP) is the method used by TV Electric to manage the CAP and ' ensure ' consistency of each contractor's efforts
. and products. Under the direction of.TV Electric, each corrective action contractor (SWEC, EBASCO and IMPELL) has developed a Design Basis Consolidation Program plan (four..in all, two for SWEC). For convenience in reporting on the efforts of the corrective action contractors,- the scope of-the CAP has been divided into eleven Project Status Reports (PSR) as follows:
Mechanical .
SWEC (1)
Civil Structural SWEC <
Electrical SWEC Instrumentation and Control SWEC 6 -
Large Bore Pipe Supports SWEC .
1 Cable Tray' Hangers EBASC0/IMPELL l Conduit Supports A&B and C Train > 2" EBASCO 1 Conduit Supports C Train s 2" IMPELL Small Bore Pipe-Supports SWEC HVAC EBASCO
- Equipment Qualification IMPELL (1) Systems Interaction being performed by EBASCO and Fire Protection being
. performed by IMPELL will be reported in the Mechanical PSR.
Reauest:
- 3. Where the purposes of the programs described in your response to Items 1 I
and 2 above are similar, clearly describe the difference and interrelationships between these programs. Include in your response a diagram showing the functional and timing relationships between each of the programs. For clarity, it may be necessary to provide a series of diagrams showing the programs in increasing levels of detail. With respect to the relationship between DBCP and DAP, specifically address the interface between these programs in each of the phases (1) investigation, (2) corrective actions, and (3) verification or overview.

Issues from sources "a" through "h" were collected and labeled external source issues in the CPRT Program. CPRT third-party (see NOTE below) addressed some I of these issues directly in CPRT Issue Specific Action Plans (ISAP) and i Discipline Specific Action Plans (DSAP). Some of the findings (Discrepancy Issues Reports (DIRs)) coming out of the CPRT DAP were grouped into Issue Resolution Reports (IRRs) issued by DAP. These IRRs will be specifically .
responded to in the CAP Project Status Reports (PSRs). The CAP contractors will. also respond to and resolve all remaining issues, (e.g., DIRs and/or l recommendations) in the project files.
NOTE: As described in the CPRT Program Plan, with the exception of the Chairman of the SRT, the CPRT third-party organization is comprised of i
personnel who are affiliated with organizations external to TU l Electric. The selection of CPRT third-party personnel was based on l- the following criteria:
l Integrity of both the individuals and the organizations with which they are affiliated based upon their reputation and standing within the nuclear industry.
Objectivity of both the individuals and the organizations with which they are affiliated based upon their demonstrated capability and reputation for providing objective, dispassionate technical judgements on the basis of technical merit.
Objectivity of both the individuals and the organizations with which they are affiliated based upon the lack of previous involvement in the CPSES project activities in question.
The following tables illustrate the trail and ultimate repository for issue and recommendation resolutions, and the projected schedule for issuance of major reports.

Attachment'to TXX-6500 June 25, 1987 Page 6 of 24-We understand the reference to " relationship between the DBCP and DAP," to mean " relationship between the CAP and DAP," since the DBCP is the method for TV Electric to manage the Corrective Action Program implementation by the ,
three corrective action contractors. As part of the DAP investigation phase, findings were compiled and provided to the corrective action contractors.
These findings were raw data, not evaluated for validity or safety j significance. The corrective actions contractors will evaluate and respond to )
each finding. The project design corrective actions will validate the entirety of CPSES safety related design, except as noted earlier, thus i bounding all DAP findings.
Reauest:
- 4. Clarify the present role of the " safety significance evaluations" and the identification of " critical design parameters" with respect to your !
redesign and construction verification efforts. Explain the ,
organizational controls you apply to ensure that these screening processes '
do not overly constrain the scope of the corrective actions required. 1 1
Response
The CPRT-QOC program included " safety significance evaluations" of findings as a mechanism for evaluating the significance of each deviation. Please refer to Appendix E of the CPRT Program Plan for a detailed explanation of the CPRT procedure for resolution of deviations. The organizational controls applied to this evaluation process include:
- a. Initial review performed by technically qualified personnel who met the objectivity criteria of not having been previously involved in the area of CPSES under scrutiny.
- b. Each evaluation was reviewed and approved by a technically qualified supervisor.
- c. A comprehensive review of the safety significant evaluations (SSEs) was '
conducted by a group separate from the Safety Significance Evaluation Group to provide further assurance that SSEs accurately analyzed the deviating plant construction conditions and therefore led to the identification of all plant construction deficencies and adverse trends.
The safety significance evaluations performed by the CPRT Programs will play i no substantive role in the design validation efforts of the TV Electric CAP.
l Because of the misunderstandings as to its intent, the term " Critical Design Parameters" will no longer be used. In any design process there must be a starting point for the engineer to define those attributes to be satisfied by the design. For CPSES, the CAP was structured to provide that starting point by capturing existing licensing commitments in Design Basis Documents (DBDs).
Existing plant design documents are then validated to the DBDs.
The engineers identified the attributes which are necessary to ensure that safety-related systems, structures, or components will perform their safety-related function. The corrective action contractors will develop
Attachment'to TXX-6500 June 25, 1987 Page 7 of 24 documentation that the installed hardware conforms with those attributes. !
Validation of the plant design against the identified attributes will provide assurance that all design requirements needed to confirm that systems, l ,
structures and components will perform their intended safety functions have been considered.
Reouest:
- 5. Identify the documentation that will be produced for each of the activities described in your responses to Items 1 and 2. Specify whether the documents will be submitted on the docket or filed at the site. It should be recognized that we will docket any information, not otherwise so .
submitted, that the staff relies on for conclusions in its safety '
evaluations.

The subject ;
of each of these reports is contained in the response to Request 2. All GIRs i have been submitted to the NRC Staff. l PROJECT STATUS REPORTS '
The documentation to be produced by the CAP will be in the form of eleven Project Status Reports (PSRs). The subject of each of these reports is contained in the response to Request 2. These 11 reports taken together represent a validation of the design to the licensing commitments and the '
-hardware to the design. Each PSR will be a living document and will describe the activities undertaken or to be undertaken by the corrective action contractor and the results obtained in the performance of their respective portions of the CAP. >
The PSRs, the Design Validation Packages (DVPs) containing the validated design and the documentation of hardware acceptance, such other validation reports as may be appropriate, the design documentation itself, and the working files associated with this activity will all be maintained at the CPSES site. The extent to which these documents may be offered into evidence in the contested OL proceeding has not been determined at this time.
Reauest:
- 6. Identify the as-built verifications and/or walkdowns that have been or will be conducted for each program. Indicate which of those verifications will be relied on for the " final" design. Inasmuch as future design changes may be undertaken for a variety of reasons, you should define
" final" design with respect to the CPRT efforts.
Resoonse:
" Final design" with respect to the CPRT effort is defined as the validated design document, with any required change identified. The CAP contractor validation of installed hardware to validate design constitutes the
" verification of final design".
The corrective action contractors, as part of the design validation phase of the Corrective Action Program, are revising the installation specifications to reflect the validated design and to resolve previously identified weaknesses. ,
An objective in revising the specifications was to identify the quality control inspection requirements and acceptance criteria. The inspection requirements will be addressed as they would be for new construction activities; as such the attributes will be identified for in-process work activities as well as final design implementation inspection activities.
i
Attachment to TXX-6500 June 25, 1987 Page 10 of 24 The corrective action contractors will validate the installed safety-related hardware ("as-built condition") to the validated design. This validation of completed hardware will be conducted by validating the final design implementation inspection activities. Acceptance of the installed condition envelopes the in process requirements. Specific validation of in-process inspections will not be done except in those instances where the in-process activity is considered in the process of evaluating the final design i implementation in an engineering analysis (Method 2 below). l The validation will be done by one of two methods:
- 1) Verification by QC reinspection or documented engineering walkdown that the final acceptance attributes are satisfactory, or
- 2) Acceptance of the as-built condition by engineering evaluation in the form I of analysis, studies, process examinations or inspection of additional !
alternative attributes which provide information concerning the I acceptability or non-acceptability of the final acceptance attributes. l These evaluations may use historical programs and procedures, prior 1 inspections, existing documentation, test results, CPRT results, and other l available information to the extent possible. :
A documentation package supporting the validation is being developed.
CAP has determined that verification by reinspection or engineering walkdown needs to be used in each of the eleven scopes of work in the CAP program.
Those areas in which utilization of Method I has already been selected, and the inspections /walkdowns are already in process, include:
- b. Cable tray hangers.
- c. Safety train A and B and non-safety train C (greater than 2 inches) conduit and conduit supports.
- d. HVAC duct and duct supports.
- e. Class IE equipment.
- f. System interaction, including non-seismic or seismic category 2 over seismic category 1 equipment and components.
- g. Instrumentation tubing and tubing supports.

CYGNA Independent Assessment Program, and vendor / contractor.QA/QC programs relate to the overall QA/QC program for Comanche Peak. Identify which of these verification methods will apply to each program. It appears that the evolution of these verification methods have resulted in a QA/QC program that is different from that currently described in the FSAR'and possibly different from that evaluated in SSER 13. Therefore, you should (1) describe the present QA/QC program.for Comanche Peak, (2) identify i differences between the present program, the program described in the FSAR, and the program evaluated in SSER 13, and (3) indicate the schedule by which you will update the FSAR to reflect the QA/QC program for future reference. In addition, explain how QA/QC has been applied to the CPRT activities over time, particularly for work performed prior to Revision 3 of the Plan.
Resoonse:
l Engineering contractors providing safety-related services to TV Electric are required to perform these services either under the purview of the TV Electric QA Program or.under the purview of their own QA Program. TV Electric QA qualifies these engineering contractors to provide engineering services in accordance with their QA Program by reviewing and approving the contractors' QA Programs prior to commencement of work. Subsequent audits of each contractor are then performed to assure continued adherence to their approved QA Programs. These TV Electric QA activities are performed in compliance with the present commitments contained in Sections 17.1.1 and 17.1.7 of the CPSES FSAR. Engineering contractors presently performing safety-related services
i Attachment.to TXX-6500 June 25, 1987 Page 12 of 24 for TU Electric include the lead contractors (SWEC, EBASCO, and Impell) involved in the Corrective Action Program. In addition to TV Electric audits, each of these engineering contractors perform periodic audits of work performed for TV Electric to assure effective implementation of their QA Programs.
The CYGNA Independent Assessment Program and the CPRT third-party efforts are exceptions to the above described normal process in that TV Electric QA did not qualify these organizations by reviewing and approving their QA Programs.
The reason for these exceptions was the fact that the third party efforts were j substantively directed toward evaluating the effectiveness of the TV Electric s QA Program, and no third party work was or will be "of record". The CYGNA 1 efforts are conducted under its QA Program which CYGNA developed to meet the >
provisions of 10 CFR Part 50 Appendix B. The CPRT third-party efforts are conducted under the CPRT QA Programs.
TU Electric relies on CYGNA to conduct audits of CYGNA activities. The CPRT requires TERA and ERC to audit their own activities and, additionally, the CPRT established an Overview Quality Team which provides an additional level of assurance that those audits are being properly conducted.
It is correct that the CPRT QA Program evaluated in SSER 13 is different than the TU Electric QA Program described in FSAR Section 17.1. The CPRT QA Program evaluated in SSER 13 was unique to the CPRT effort and only applied to 1 that effort. Prior to Revision 3 of the CPRT Program Plan, the CPRT third-party contractors for the DAP and QOC areas, TERA and ERC respectively, conducted their activities related to implementation of the CPRT Program Plan in accordance with their written QA Programs and implementing procedures in effect at the time the activities were conducted. Implementation activities related to the TRT ISAP areas were conducted in accordance with the CPRT Program Plan principles and Policies and Guidelines in effect at the time the activities were conducted. All completed results reports, regardless of the responsible review team leader or the time the activities were conducted, have been subjected to the detailed working file review described in the CPRT Program Plan, Attachment 4 of Appendix G. This working file review, which was completed prior to SRT approval of the completed results reports, was conducted as an additional level of review to ensure that the quality of the documentation demonstrated that the Action Plan was completed as approved by !
the SRT, supported the conclusions and work reported, and was consistent with )
the requirements of the CPRT Program Plan. Additionally, the Overview Quality 1 Team conducted reviews of the working file review activities to assure that '
those activities were accomplishing their intended objectives.
The TV Electric Technical Audit Program, which commenced in January 1987, is an integral part of the CPSES QA Program. It is an extension of the TU Electric QA Audit Program described in Section 17.1.18 of the CPSES FSAR.
The purpose of the Program is to conduct an extensive series of technical l audits of corrective action activities performed by TV Electric and its '
engineering contractors to provide an additional level of confidence in those activities. TV Electric Technical Audit Program activities are coordinated with the audit activities of the engineering contractors to maximize audit coverage and reduce duplication of effort. The TV Electric Technical Audit Program is one of the activities / programs that the SRT relies upon to perform its overview function. The extended TV Electric Technical Audit Program will remain in effect until completion of design activities associated with the

3 Page 13'of 24 Corrective Action Program. At that time technical audit activities will resume a reduced, less extraordinary intensity of effort.
The Engineering Functional Evaluation (EFE) is a special effort to be.
patterned after.similar SWEC efforts conducted at Millstone 3, Nine Mile Point i -- 2, and Beaver Valley 2. Those efforts were accepted by NRC Staff for those jobsites'as alternatives to Integrated Design Inspections-(IDI) or-Independent Design Verification Programs (IDVP). The Engineering Functional Evaluation will be conducted under the SWEC Engineering Assurance Program described below. The Engineering Functional Evaluation. is another activity / program the SRT will rely upon to perform its overview function.
The SWEC Engineering Assurance organization is responsible for performing-audits and surveillances of SWEC engineering activities.for CPSES to ensure the engineering activities are conducted in accordance with NRC-approved =QA Topical Report, SWSQAP 1-74A (The SWEC. Corporate QA Program). The SWEC QA Topical l Report has been approved by. TV Electric QA. SWEC Engineering Assurance activities, with the exception of the Engineering Functional Evaluation effort described above, .are audited by TV Electric QA.-
The evolution.of the various efforts described above has not resulted in a QA program that is different from that currently described in Section 17.1 of the CPSES FSAR. While all of the contractors or their efforts are not specifically described. in the FSAR, their CPSES involvements are fully consistent with the provisions of the FSAR QA program description. Therefore, there is no need to revise the QA program description contained in the FSAR.
The following table summarizes the various contractor QA organizations as they apply to CPSES activities.

T 18.,7dp53ER 13, the staff noted that the design activities and, by C-impWeation, the quality programs of,certain " proven" vendors may be exempti from a design adequacyjovaluation; for example, the vendor for the
%! nuclear steam supply system. Mease identify other vendors that you l 1 'V believe would fall into this (.stegory, in that you feel that their design .

gns of equipment supplied by vendors has an NRC-approved i ; O Design Qdality Assurance Program. In addition, the Westinghouse NSSS design
- c has bees thorougtily.. reviewed and audited on numerous occasions by independent l' Q p ' 'and/or outside individ1als and groups.
Simila'rly, suppliers of safety-related equipment have provided equipment over '
y$ , c number %f years to numerous plants. The functionality and design adequacy l 4", of their equipment have been demonstrated through use in operating plants. In j 4' > addition, the equipment is required by specification to be or have been 1 performance tested in the shop and/or in the field.
3-Venders supplying ASME components'also have ASME QA Programs which undergo surveillance, y .-
.P*
i- The interface between the Architect Engineer (A/E) and the NSSS and other vendors will be evaluated in CAP by reviewing the documentation supplied by them to demonstrate conformance to specifications. The design interface for
,' f . each of these suppliers is being reviewed in CAP.

M J 9. Please explain what the role and purpose of the Senior Review Team (SRT)-
- will be in the future. We believe that this role should be explained i 9 particularly with regard to the transition from the CPRT to TUEC l
/ responsibility for implementing the Plan. l i
(s '
Respontql l i The original and unchanged role and purpose of the Senior Review Team was to
, formulate policy and provide overall direction of CPRT activities. In )
addition to this policy-setting and management responsibility, the SRT has l been tasked with reaching a conclusion regarding reasonable assurance that i CPSES has been designed, constructed, and tested such that it is capable of i being operated in accordance with NRC regulations. i The responsibility for formulation of the CPRT Program Plan and ultimate !
sponsorship of its published results rests with the Senior Review Team of CPRT. The CPRT effort has proceeded in three distinct phases: investigation, j corrective action and overview of corrective action. The initial investigatory responsibilities rested with previously uninvolved personnel or l organizations (" third parties"). The TV Electric decision to move directly to l

.a full-scope corrective ~ action program has obviated the need~fnr certain CPRT activities designed to determine.the bounds of necessary corrective actions.
. Corrective action implementation' has always been the responsibility of TV -
Electric. The responsibility for corrective action overview has been and' still is with the third party. - Description of the third party corrective action overview activities is provided in Rev. 4 to the CPRT Program Plan.

- 10. With respect to the CYGNA Independent Assessment Program, theLstaff notes that recent Phase IV activities appear.to have value as an adjunct to the Technical Audit-Program. .Please indicate the extent to which the CYGNA evaluation will.or can apply to any of the programs described in your -
response to Items-1 and 2.
Response
The' CYGNA Independent Assessment Program is a stand-alone effort. The Overview Responsibility matrix in response to Request 7 identifies the Corrective Action Program (CAP) activities which address CYGNA issues and involve CYGNA' concurrence with resolution of those issues.
-To the extent that the above listed' activities-involve CYGNA concurrence with resolution of issues emanating from the CYGNA charter implementation, there is an ' augmentation of the Technical Audit Program. The CAP effort is anticipated-
'to result in. closure ~of the CYGNA issues.
Reauest:
- 11. During the April 7, 1987 meeting, you provided. listings of " licensing open items" other than those included as part of CPRT and related activities.
We request that you provide the status of the resolution of those issues.
The status should include identification of those issues that will require plant modifications, interfaces with CPRT. activities (i.e., dependencies),
and projections for future FSAR amendments.
Response
Below is a list of the licensing open items presented at the April 7,1987, meeting and the information that you requested. Please note that nothing in.
this table signifies that to any extent any item is properly within the scope of the contested issues before the ASLB.
