I Executive Summary l The Design Basis Consolidation Program (DBCP) for the Comanche Peak Steam I Electric Station (CPSES) is a program to create a set of consistent design documentation which demonstrates that the design of safety-related systems, structures and components is in conformance with governing design ciiteria I- and licensing commitments. This program shall apply to SWEC design responsible areas and interfaces with other lead design contractors. This program will consolidate existing design criteria into a set of controlled Design Basis Documents (DBDs) that fully and accurately reflects the current licensing commitments of CPSES. Using selected critical design
- } parameters, the as-built plant will be assessed for conformance to these 1 criteria. Design documentation will be assembled, reviewed and upgraded as required so that it is sufficient to dme.on s t ra te the acceptability of the desiga. The individual and cumulative design effects from NRC and Comanche Peak Review Team (CPRT) identified concerns will be incorporated into the DBCP.
"} The completed product will be a set of Design Validation Packages (DVPs) 8 which contain plant design documents and evaluations which demonstrate design acceptability. Acceptability will be determined by evaluating design documentation, representing CPSES as-built conditions, to established design criteria. Any design or documentation changes required, and the status thereof, to reach this goal will be identified in these packages.
In addition, selective programmatic improvements will be identified and implemented to support the DBCP and provide the necessary control for assuring that future design work will be documented in a controlled manner
- that verifies consistency with the design basis.

1.0 PURPOSE : u 7 The purpose of the Design Basis Consolidation Program (DBCP) for the -{ g Comanche Peak Steam Electric Station (CPSES) is to evaluate the l acceptability of safety-related syst ems, structures and components and to ; provide a consistent set of documentation which will serve as a basis for future plant evaluaticJs and decisions during operations. _i l - The basis for evaluating acceptability will be current licensing commit- i meats, established design criteria and CPSES as-built conditions as depicted ;. on design documentation. Actions taken in response to concerns and results . ' 6 from the Comanche Peak Response Team (CPRT) Design Adequacy Program (DAP) ; and Quality of Construction (QOC) Program will be resolved in the DBCP. Items from these programs which affect the design basis or design basis
}4 g . p' I calculations will be considered appropriately with other design requirements i<
such that the final design is evaluated on a consistent overall basis. c
.g 2.0 SCOPE
-31 3
The scope of the DBCP covers CPSES safety-related systems, structures and - components as well as certain features of other systems, structures and components required to assure plant licensability. Design responsibilities 2j have been assigned to various engineering contractors as outlined in -? Section 3.0. This document details the DBCP program as it relates to the design responsibilities of Stone & Webster Engineering Corporation (SWEC) _; b including civil / structural design, mechanical design, electrical design, I&C f? design, and the interfaces of these areas with other contractors. The . i piping and pipe support DBCP, although assigned to SWEC, has been presented ; separately in a previous submittal. The piping and pipe support interfaces - with this effort are discussed in this document. 'r [
3.0 BACKGROUND
s, [ a P s The Comanche Peak Response Team (CPRT) program plan was formulated by Texas _l Utilities Generating Company (TUGCO) to resolve various construction quality ; and design issues raised by the Atomic Safety and Licensing Board (ASLB); id the NRC staff's Technical Review Team (TRT), Construction Appraisal Team () (CAT), Special Investigation Team (SIT) and Supplemental Safety Evaluation l Reports (SSERs); Intervenor Citizens Association for Sound Energy (CASE); 7 pl - and Cygna Energy Services Independent Assessment Program (IAP). In addition .j B to responding to these external issues, the CPRT is also conducting a i !i self-initiated evaluation of the CPSES quality of construction and adequacy of design. 'yf
-D Within the overall CPRT, the DAP, managed by TERA Corporation, has conducted y investigations of the adequacy of the CPSES design and design process. t i These investigations have centered on concerns related to both external and ;,
self-initiated issues. Noted discrepancies were documented and reported to 1 TUGC0 on Discrepancy Issue Reports (DIRs). The DIR is appended to a TUGC0 ,i Design Deficiency Report (TDDR) which enables TUGC0 Engineering (TE) to 2i evaluate the problem and develop a disposition and any corrective / preventive action that may be necessary- TERA he further evaluated the DIRs generated )] and developed Issue Resolutiva Reports (IRRs) which categorize design .I discrepancies into groups whig nave similarities and may have potential d h . : M07-1634503-B2 1 z 1 4 e
. , . ,i
technical or programmatic significance. In response to the IRRs, Generic Issue Reports (GIRs) have been prepared for the civil / structural,
=
electrical, instrument and control, and mechanical disciplines. Each TDDR and associated DIR will be evaluated by SWEC and resolved with TERA. The QOC Program is tasked with evaluating the adequacy of CPSES construction 2 and the implementation of the construction related QA/QC program. This program is managed and documented by Evaluation Research Corporation (ERC). Identified deviations are documented and reported on Deviation Reports (DRs). Resolution of valid DRs is ultimately achieved through initiation f and processing of a TUGC0 Nonconformance Report (NCR). ERC develops and issues population reports which summarize the deviations identified by the
'_ QOC program. These reports are reviewed for design implications and factored into the DBCP.
In parallel with the CPRT program, TUGC0 initiated in 1984 the Design Basis Document (DBD) program. In establishing a functional engineering organiza-tion, TE recognized that the process of design control and configuration management would be enhanced if major design inputs were consolidated into controlled documents which could be maintained current. This program is in progress with DBD development assigned to the various lead design contractor organizations.
=
The CPSES DBCP is an extension of the DBD program. To further enhance the configuration management process and use of CPSES design products during plant operations, CPSES design basis inputs and criteria will be confirmed to validate the design to that basis. Several design organizations are presently contracted to TUGC0 for current g design services associated with CPSES. These contractors will contribute to , 8 the overall CPSES DBCP by virtue of their currently assigned design valida-tion responsibilities. Close interface among these organizations, exchange
, and use of design validated information, and complete interface between A Design Validation Packages (DVPs) are paramount for the assurance of program consistency.
k Currently, the organizations perfo rming design and design validation activities which interface with the DCP, include the following: [ TUGC0 Engineering (TE) - Responsible for the overall coordination of design organizations and the development and maintenance of project design control procedures. 1 _" Gibbs & Hill, Inc.

I 4.0 DESIGN BASIS CONSOLIDATION PROGRAM - 4.1 Overall Approach The DBCP is a multi-step process to collect and document CPSES design criteria, to evaluate detailed design documents, as-built data and test data and to demonstrate that design criteria have been acceptably considered in l I the design process for CPSES. The product of this program will be a set of design documentation which is consistent and technically acceptable. simplified presentation of the DBCP flow path is presented in Figure 1. A The program will start with the collection of design criteria for safety-elated structures, systems and components into a controlled set of DBDs. , The plant design will be divided into discrete packages (e.g. systems) " I including all associated design documentation. Each package will be assessed to determine the critical design parameters required to assure accomplishment of plant safety functions. Where it is determined that _ j l design documentation does not recently reflect as-built conditions, then it
! W will be confi rmed that the as-built facility meets design criteria
[' requirements. Existing drawings, calculations, specifications and test data will then be reviewed to determine whether the existing documentation demonstrates that the as-built design meets design criteria required to
! accomplish plant safety functions. Where it is determined that design y documentation does not recently reflect as-built conditions, then it will be
[ l 5 confirmed that the as-built facility meets design criteria requirements. Where the existing g documentation is inadequate to provide this [ demonstration, it will be upgraded or supplemented as appropriate. _ The establishment of the design basis and the aasessment of design will t consider individual as well as the collective and generic significance of f g the findings from the DAP and QOC Programs and their resolutions. ir g ?

Since the design information no rma l ly provided in the CPSES DBDs prepared in accordance with TUGC0 Engineering procedures must be validated, the DVPs will be generally provided in Appendixcategorized A. in accordance with the DBD breakdown listing .. DBD categories may be combined into a single DVP for purposes of streamlining validation activities. In addition, the safety-related DBDs listed in Appendix A may be further subdivided or additional DBDs identified as required. - 4 Each of that DVP will identify and contain the following items related to the scope package: , . t.f -

NRC TRT Concerns and Resolutions Incorporation of design commitments / requirements as established in I' resolution of SSERs, Notice of Violations (NOVs) Notice of Deviations (NODS), Significant Deficiency Analysis Reports (SDARs) and Corrective Action Requests (CARS). Design Documents (Drawings, Diagrams, Specifications, Calculations, etc) Changes to QC inspection and test program procedure attributes and/or . 1 accept / rej ect criteria that are necessary to implement DBCP initiated design changes. W Design responsibility interfaces will be identified and cross-referenced among interfacing organizations in each DVP. Boundaries of validated design will be identified and documented. A distinction should be made between DVPs and DBDs. The DBD describes the plant design criteria and the plant design which fulfills that criteria. The DVP contains the design basis, production, construction, testing, I operations and licensing documents which exist as proof that CPSES design complies with its criteria commitments. Typical design validation ccacepts are provided in Appendix C. 4.3 Design Criteria 4.3.1 Design Basis Documents I Those DBDs to be prepared have been identified by TUGC0 and development assigned to lead design contractor organizations. structure, system and special subject design basis documents. DBDs consist of System DBDs I address system design criteria and functional requirements to include mechanical, requirementt,. instrument and control, electrical and operator interface In preparing DBDs, key design documents (flow, instrument and control, and electrical one line diagrams and elementaries) and other design related documentation (as-built, test, vendor information, and CPRT I findings) wi' l be reviewed for compliance with licensing criteria and the identification of additional functional requirements. This initial review will permit engineers to develop an understanding of the general plant and I system design and will allow for the completion of the initial DBD. During execution of the DBCP further design information and changes will be identified requiring DBDs to be updated. DBDs, representing criteria against which the CPSES design has been ultimately validated, will be completed and form a part of the final DVP. 4.3.2 Critical Design Parameters The process of the DBCP to evaluate the acceptability of systems, structures y I and components to meet their intended safety function includes the identi-fication of critical design parameters. Critical lesign parameters are p 6807-l^34503-B2 5
[ those criteria which must be satisfied by the CPSES plant design to support safety-related licensing commitments. These include such parameters as design pressure, temperature, flow, equipment capacity, analysis parameters, , etc., for plant systems; electrical parameters include offsite and onsite L power system voltage profiles, distribution system ampacity and line losses, equipment terminal voltage parameters, protective devices criteria, etc.; / structural parameters include steel / concrete criteria, seismic / geologic ! criteria, support systems criteria, etc. - The validation of each product will include the selection of design parameters on the basis of their criticality to support licensing commit-q ments and ensure safety function capability. These parameters will be used in evaluating the as-built design conformance with applicable design crite- ) ria. Upon completion of design validation, actual plant design will be substantiated by the des.gn documentation. 4.4 Design Validation Methodology L 4.4.1 General The design validation will evaluate whether the available design documenta-f tion adequately demonstrates that the as-built design meets the critical design parameters in accordance with licensing commitments. . . . The design documentation for a DVP will be reviewed to verify that the assembled package provides consistent demonstration that design criteria related to that DVP have been met. For example, in order to determine if sufficient fluid flow is developed in a particular system, the flow diagram, piping drawing, pump specification, pump vendor performance data, fluid system calculation, motor capacity, preoperational test data would all be reviewed to assess whether this combined set of documentation provides adequate demonstration of flow capability. I The DBCP shall include identification and resolution of document I inconsistencies, preparation of final DBDs and issuance of a DVP for each .. L safety-related design segment. The program will address those design y parameters / products necessary to adequately confirm that each safety-related e system, structure and component will perform its intended safety functions during postulated plant operating and accident conditions. The following items will be considered during the design validation:
- Findings identified from the CPRT QOC program I
- Findings identified from the CPRT DAP
- Application of committed codes and standards
- NRC I&E Bulletins
- Consistency with the SER and supplements
- Consistency with the TUGC0 Licensing Commitment List currently under development

4.4.2 Discipline Reviews 4.4.2.1 Mechanical
'The mechanical design validation will, in general, be performed on a system ,~ l basis with each safety-related system being addressed in a DVP. Such a e package will include the mechanical as well as other (e.g., electrical and controls) aspects of system design. Further discussion relating to a typical system DVP is included in Appendix C.I.
Some aspects of mechanical design do not conveniently lend themselves to packaging by system. These will be addressed on a subject basis and include I such topics as piping design and installation, inaulation, safe shutdown evaluation, welding, shielding design, analysis and accident radiological analysis. accident pressure / temperature The goal of the mechanical design validation program is to verify that all safety-related mechanical systems have sufficient design basis and as-built g documentation to comply with licensing commitments, and are substantiated by g the start-up testing program. Design btsis criteria will be established by reviewing FSAR commitments, SER and it amendments, and existing TUGC0 criteria documents and correspondence. In addition, CARS, SDARs, and QOC r
-lW issues will be considered in developing these criteria. This is done to establish the basis for the existing equipment and systeas. Once this has been established, the criteria sections of DBDs will be developed in I accordance with TE Reports ER-SYS-5, 6, and 7 requirements. The resulting criteria sections of the DBDs will serve as the basis for verification of t,mpliance with licensing commitments.
With the approved licensing commitments firmly established, the mechanical discipline design validation review will ensure that critical safety parameters are reflected in the design and design documentation. I 4.4.2.2 Electrical The electrical design validation effort will consist of document reviews I (electrical DVPs) of electrical systems or subjects (i.e., 480V and 120V electrical distribution system, electrical independence Reg. Guide 1.75) and reviews of documents which will be included as part of other discipline DVPs (i.e., electrical distribution to components). Validation will be performed to ensure that the electrical distribution system, its interface interconnection with fluid systems and other I electrical functions will meet their intended functions during all plant operating and accident conditions. The electrical distribution system consists of the following: i I
-asummL c- ' 5
- Medium Voltage Distribution System
-
- 480 V Low Voltage Distribution System 5 120.V Low Voltage Distribution System
- Uninterruptible Power Supply System
- DC System The sources of electrical power to the electrical distribution system are:
- Offsite pcwer which is obtained from the electrical system power
-i ; grid via the electrical switchyard, and
- Onsite power which is normally provided by the turbine generator,
}_ and by diesel generators during emergency conditions. Tbe electrical distribution system distributes both normal and emergency 3 electrical power via interconnections to electrically driven equipment in W fluid systems, a To validate that these systems are adequate, the documents that represent
; these systems must be reviewed to ensure correctness and consistency with their DBDs and FSAR commitments. Where feasible, other metheds utilizing test results may be used to represent correctness of design drawings such as q wiring diagrams.'
4.4.2.3 Instrumentation and Controls (I&C) 5 j I&C DVPs will be comprised of design documents, drawings and reports which have received comprehensive reviews of ISC systems. Also, I&C will review their discipline drawings and documents which will be included as part of 2a mechanical and electrical systems DVPs. For each system the validation of I&C requirements will assure that the
; design will result in the component _ operation required by the design a criteria. Test results will be evaluated to verify that they support the conclusion that the design meets the governing criteria.
3 The SWEC I&C design validation of the CPSES will, in general, be accom-plished as follows:
-;
- Design source input drawings and documents (i.e. flow diagrams, I one line diagrams, instrument and ccatrol diagrams and DBDs) and CPRT findings will be reviewed to verify that I&C inputs are g correct, comply with industry practice and standards, and also that regulatory requirements have been incorporated where applicable.
j
- I&C specifications, instrument drawings, electrical elementary diagrams, NSSS supplied interface drawings, vendor drawings, main control board, relay panels, instrument isometrics, annunciator,
_ and computer system drawings will be reviewed by I&C for

- 1. Scoping review of the existing calculations which includes:
- Review of documents relating to the structures as-built _
B conditions (i.e., specifications and drawings and CPRT findings). -
- Review existing calculations
- Categorize xist:ng design calculations into various levels _

- effort. -.
m .. 4.5 Interfaces g 4.5.1 Interface Between DVPs The engineering and design process of CPSES required a multi-discipline
- engineering interface in the application of design criteria to the produc-tion engineering process. Direct, procedural interface ties exist among the .
f. civil / structural, mecnanical, electrical and I&C engineering disciplines in implementing consistent design criteria. Ancillary interfaces exist among g these four major disciplines with other speciality engineering groups for
- _" plant analysis, process and environmental system design requirements, and programmatic development of generic design criteria.
. These same interfaces will be maintained throughout the validation program, -
with project procedures controlling the interface flow and use of validated 2 design information. Just as mechanical systems not only interact and compositely function together, but share a commonality of design require-ments, these systems also interact with structural, electrical and I&C . , design and functional requirements. This necessitates direct interface of validated design information among design validation activities. As such, references between packages to identify input and shared design bases will
, be included for continu'ty and consistency of design products. The sum . .
; total of 'WP ' s will constitute complete design basis validation for CPSES safety-related systems, structures and components. y c , . ...

L w be compared with total plant design criteria to ensure that a complete set of design basis documentation packages is developed for safety-related ; systems, structures and c on.p o nen t s . Clarification of the interfaces will f necessarily take place on a day-to-day basis at the working engineer level. Documentation of agreed upon boundaries of design responsibility and ex- ~ ! change of validated design data will be included in design validation packages within each design contractor's scope of responsibility, resultant design validation products must be identified and exchanged among contractors. These products are the validated design documents themselves and not simply final DVPs. Since design information validated by one contractor may be input required for another contractor's validation activi-ty, it is critical that the exchange of information among contractors take - place in a formalized but timely manner prior to issuance of a DVP. To accomplish this, each contractor will identify the products it intends to produce and what products it requires from others. 4.5.3 Interface with Design Adequacy and Quality of Construct ion Programs The DBCP will capture the CPRT Program issues by identification of design f criteria and the evaluation of plant design adequacy. The DAP and QOC 1 issues will be evaluateo to identify those design adequacy parameters, documents or activities which may be affected. The critical design -- parameters and the design basis documentation, identified by formal issues as requiring upgrade or resolution, will be included in the DBCP. CPRT issues will be dispositioned and resolved by the specific discipline asso-ciated with the observations as part of the DBCP to assure that cumulative effects of these issues do not prevent the plant design from meeting its required criteria. 4.6 DBCP Documentation The design documents within the scope of each DVP will be validated by - comparison to the design criteria and by establishing consistency with other related design documents and the as-built condition of the plant. As the validity of each i lividual design document is established, a validation sheet will be attached which will cutline the document review and conclu- _ sions. Each validated document will be filed with its validation sheet and 5 an entry made in a Validation Index to track the progress aad completion of the validation effort on individual design documents. The index will be computerized and will initially contain all known design documents and the design package or packages to which they are assigned. The status of each document will be updated as the etfort progresses until each document within the package is validated. -. Some design documents or design criteria documents may be revised due to the j review process to achieve consistency between documents or to implement J hardware changes required to correct discrepancies. The index will be revised to include any change of document status or document revisions. At the conclusion of the validation process, a complete set of validated documents will be turned over to TUGCO with an evaluation report. The 4 evaluation report will summartze the results of the conclustons and changes 4

k c made as a result of the review and accompany the sets of completed validation packages.
.i As a consequence of this review, all DAP and QOC issues should be resolved.
At appropriate times during the effort, TDDR/DIR resolutions will be l documented for closure. Z 5.0 DESIGN COMPLETION Design change and interface control becomes increasingly more important as the plant design progresses. It is extremely important that design changes be identified, completely scoped, and then implemented in a manner such that all affected engineering is reviewed and revised in an orderly fashion.
-Without this level of control, plant design documentation will be inconsis-tent, as a minimum.
a 3 The DBCP will be initiated based against CPSES design criteria, design basis documentation and as-built plant design effective October 1, 1986. CPSES design will be validated using issued design documents as of this date. This will form a baseline design basis for CPSES, against which future design modifications can be implemented. _ Necessary plant design changes ensuing during the validation process will _ ,either be included in the validation at the time of design change evaluation or will be reconciled against the DVP upon completion of the validation process. The project will review the existing CPSES design change control procedures and the existing methods by which engineering information is transmitted, reviewed, and implemented among all of the engineering organizations involved in the CPSES design activity. The basic goals which these methods / procedures should address are: 5
-
- Provide timely notice to all affected disciplines that a design change is being considered.
i
- Identify the entire scope of a change prior to change approval.
- Include licensing, feasibility, cost, schedule, and construction impact in the decision process.
- Provide for scheduling and tracking of the required document changes, g hardware deliveries, and should input this information into the plant
_- engineering and construction schedules.
- Provide for a review to determine the timing of changes; i.e., pre- or
- A post-system turnover, system testing, fuel load, etc. in order to i minimize impact on plant completion schedules.
-E
- Establish provisions for reconciling unvalidated design basis informa-I tion used in design-engineering packages for plant design modifications.

Design change control procedures will ensure that future design modifica-tions to plant design are incorporated into affected engineering and design documents; i.e., design basis documents, production engineering documents, construction, testing and operations documents and licensing documents. =i In order to ensure that all future design work will be based upon a single = set of design information a master equipment data base will be established and controlled to assure that engineering contractors, construction ss personnel and operations personnel will all be using the same data. 5 6.0 PROGRAMMATIC IMPROVEMENTS M The DBCP as described thus far is a retrospective p rog ram in that it will review completed design work. Future design process acceptability will be assured by upgrading past design practices and programs as required. a
/ Based on an cverview of the findings from the CPSES DAPs, there are several areas where enhancements to past practices and programs woeld minimize the ; probability that similar findings would occur in the future. Identified -; programmatic concerns will be evaluated and the resulting programmatic enhancements identified and implemented. These would typically include procedural changes, indexed control of design information, and additional i personnel training.
E 7.0 QUALITY ASSURANCE
$ ~
The DBCP will be conducted under a Quality Program and procedures which comply with Appendix B to 10CFR50. The civil / structural, mechanical, electrical and I&C portions of the DBCP will be conducted under SWECs
-] " Management Plan for Project Quality" (PP-001), and Project Procedures. The SWEC quality plan interfaces with existing TUGC0 programs for compliance with their QA program commitments and engineering requirements. Addi-
[ tionally, the plan implements SWEC's Co rpo ra te QA Program. The SWEC _a Co rpo ra te QA Program complies with 10CFR50 Appendix B, and NRC Regulatory Guides and is described in an NRC-approved, QA Topical Report, SWSQAP l-74A, s " Stone & Webster Standard Nuclear Quality Assurance Program." Project procedures will provide control over the design validation process and the documentation of results. In preparing these implementing proce- _3 dures, the project will full; apply the concept that the design process is an integrated process beginning with establishing design inputs and require-ments, developing basic diagrams and drawings, preparing production drawings 3 and specifications, and concluding with control of change during
~
construction and interface with the plant test program. This concept will be applied to both the reconstitution of the design basis and validation of
, existing design activities and production design activities. This approach will not only allow the project to effectively meet it- design responsi-bilities but will also establish the framework for an established design baseline for eventual transfer of design documentation to TUGCO. In doing 2 so, TUGCO will be able to effectively and sufficiently control the destgn during plant operation.
A comprehensive program of planned and systematic audits will be conducted y to determine whether the Quality Plan is adequate, complete, and consistent -} - 6807-1634503-B2 13
3- i i I with the assigned Scope of Work; how procedures are being implemented; and the effectiveness of the program. Audits will be conducted on related I engineering and design activities. The plans for conducting audits on CPSES activities will involve an appro-l priate combination of the following two audit categories. Program Audits l I evaluate the degree of compliance with established procedures. System ' Audits (an in-depth technical audit) evaluate the technical adequacy of a portion of the design with respect to selected technical attributes. 8.0 TERA OVERVIEW i Consistent with the CPRT Progran Plan commitments, TERA Corporation, as i Manager of the DAP, will conduct an overview of the implementation of the DBCP.

i q J. 9 3.a;; ms-W$fi&lBGB C.1 FLUID SYSTEMS In order to implement a system design validation program the system valida-t' ion engineers must start with a complete and clear understanding of the approved licensing commitments and design basis requirements as well as a complete knowledge of the system design process methodology. The validation engineers will comprehensively review the design basis documents and the detailed engineering products to ensure that critical design parameters have been adequately defined in the system design. The system validation
- engineers will reviea the following types of documents for a typical system , to ensure that requu ements associated with these critical design parameters have been implemented in the design.
- Design Basis Documents
- Flow diagrams
- Logic diagrams
- Electrical one line diagrams
- Elementary Diagrams
- Specifications
- Calculations for proof of design
- Piping Isometrics
- Pre-operational Test results
- Arrangement diagrams
- Special reports or studies
- EQ documents
- Vendor drawings, manuals, seismic / stress reports
- Emergency operating procedures The specific tasks identified for system validation are:
- Review FSAR and SER commitments against existing design.
- Verify that Westinghouse has completed the Proof of Design Analysis to ensure that the documents (calculations) are in compliance with syr '.em perfo rmance criteria
- Review flow and logic diagrams for FSAR and code compliance, classification, component selection, system operability, and
.. conformance with as-built conditions.
- Review and update component specifications, vendor documents and drawings, reports, manuals and qualification documents to current design.
i
- Review, develop, and issue system related design basis documents:
system description DBDs, valve list, and line list.
- Review and update modes ot operation (stress input and operation -
needs) to current system design pressures and operating tempere-tures. 6807A-1634503-B2 C-2 k
- Review and update system calculations required to support the _
2 design basis. The review will check that proper methodology and E assumptions are used and described in the calculation and all i f others shall be voided. References will be checked for complete- ! a ness and applicability. New calculations will be developed to i I document the system design basis if required (e.g., system design pressure and operating temperatures). !
- Review and update design specification to conform with new and I
- revisions to design basis documents.
Verify that installation requirements are consistent with design criteria. B
- Review startup test procedures and results for safety-related systems to check that the systems operate as designed. {
~
The design verification group will also be responsible for:
- Evaluation and resolution of CPRT issues.
- Design criteria document review, updates, generation and issuance.
- System overpressure protection evaluation and relief v:lh adequacy (setpoint and capacity).
- Systems Interaction - Interface of existJnn er.fe nnutdown and mitigation analysir p.d fN.H g :. Ladies for conformance with sy:tes ed dn *gn basis documents. 3
- Fire hazards m N is - Interface with TUGC0 in the review of fire loading, it:s detection, fire protection, and safe-shutdown I analysis for conformance with design basis documents.
The following list of critical design parameters is not intended to be comprehensive of all parameters to be reviewed, but is indicative of those L I aspects within the design that would demonstrate compliance with licensing comraitments and design basis adequacy for a typical fluid system.
