The IRC Chairman will be responsible for obtaining the IRC's review of the planning documents and procedures for performing the verification C                                      program. This includes the audit plan, the protocol, and the individual procedures required for the work.- The IRC will review the findings of the VT for extent and for significance. They will also review the responses by NU after they have been accepted by the VT. The IRC may also make specific recommendations regarding the scope or methodology of the verification process as the work progresses.

                            ' 3.2 '    Verification Team-The VT is the core of the ciganization and is the group that does the actual review of the design and licensing bases and the effectiveness of the NU corrective actions. The VT is organized lato four functional groups. Each subgroup will be headed by a Lead engineer and will be responsible for a portion of the overall verification program. There will be a System Review -
Group (SRG), a Programmatic Review Group (PRG), an Operations and

Mitigation Systems Group (ARG).
The VT has been organized functionally in accordance with the review processes instead of by traditional engineering disciplines. However,' this is not to imply a strict compartmentahzed group strudure or review process.
I                                        It will function as a single project team with significant cross utilization of L                                        personnel among groups. It is expected that SRG and ORG personnel will I:                                    ' perform review functions associated with the ARG and PRG In addition, there will be significant interfacing among the team members and the
    ;                                  Review Group Leads. Periodic full project team meetings will bJ conducted by the VT Manager in addition to periodic review group _
meetings conducted by the Leads. During the review and discrepancy resolution process, it is expected that the VT Manager will have daily briefings with the VT leads to discuss potential findings, share lessons learned, and discuss other project issues; Teamwork and frequent communications is a fundamental attribute for the conduct of the ICAVP and will be facilitated by the location of nearly all of the Chicago office project team members on the same floor of Sargent & Lundy's (S&L) offices.
The SRG will perform the in-depth review of the selected systems. This group will review the current system output documents and analysis to verify conformance with the design and licensing bases. The SRG will also review design modifications to the selected systems made since receipt of -
the OL, focusing on the validity of the design process, idemification e system interface requirements, potential synergistic effects of the modifications, and appropriate design document controls.
The SRG will also be responsible for verifying that the current, as-built condition of the plant matches the current design output documents. This task includes physical and functional walkdowns of the selected systems (6)                                                            l

                                          ' S&L's review, it becomes necessary to review items related to systems for which the NU CMP process has not been completed, a " place-holder" shall be utilized to discontinue that portion of S&L's review until such time that NU completes the CMP process for that system. Place-holders shall not be -
communicated outside of S&L.
4.1      Defining System Boundaries The systems to be included in the scope of the ICAVP program will be defined by the Nuclear Regulatory Commission. At the beginning of the
                                          - system ruiew process, a meeting will be held with the NRC, Nuclear Energy Advisory Council (NEAC) and NU to finalize the boundaries of the selected systems and interfacing systems. In general, the systems boundary will be limited to the safety related portion of the selected systems. S&L's
                                            - review for the vertical slice system will address interfaces with the selected systems as follows:

review were addressed in the design of the interfacing system. We will review the output I&C signals for the system under review through to l-                                  the input point of the interfacing system. The extent of this review is described in detailin Attachment 6.3 ofPI-MP3-02.
* Electrical Interfaces - Electrical' interfaces will be treated in a slightly different manner. A- detailed review of the electrical distribution system        ,
from the motor control center or switchgear, as applicable, to the load -
is included as part of the selected system review, A load path review
                          ,          will be performed for the remainder of the electrical distribution system

The vertical slice system reviews will be' performed by the SRG in -
accordance with PI-MP3-02 and 03, System reviews will focus on two !
objectives,1) to verify the system design elements being reviewed are technically adequate and consistent with the licensing and design bases (PI-
                                          . MP3-02) and 2) to' verify the modifications implemented aAer receipt of the operating license are technically adequate and that configuration control of '
design documents was maintained (PI-MP3-03).
The first step of the process is to review the licensing and design bases documentation to identify the functional, design, performance, operational and testing requirements of the system. These requirements will be .
individually tabulated on a system requirements checklist by the SRG, The ORG will review the licensing and design basis documentation to identify
                                            ~the system coerating, maintenance and testing requirements. The ORG will
                                          - also use'the system requirements checklist to tabulate their requirements.
The system requirements checklist will be independently verified prior to its use by the SRG and ORG as the bases for verifying design conformance to the design and licensing bases. Discrepancies between the design and licensin; bases documentation identified during the development of the system requirements checklist will be processed as discrepancy reports in accordance with Subsection 4.8.
Following the development of the system requirements checklists, the SRG -
will perform the four reviews described below. The purpose of these reviews is to verify the current system design is capable of the functional
                                            . and performance requirements identified in the design and licensing basis documentation and to ensure consistency between the various design output documents and design process documents. Verification that current system operating, maintenance and testing practices and that current configuration is in accordance with the design and licensing basis (11)                                                              l m

documentation will be performed per sections 4.5 and 4.4, respectively.
These four reviews include:
: a.    . A review of design process documents to verify the technical adequacy of each document and its conformance to the design and licensing bases. This review will include mechanical, electrical, .
I&C, and structural calculations, piping analysis and equipment -
EQ/SQ reports. The design process document conclusions and/or Hm --_                    - ._--- . assumptions will be verified against actual operating data,.where          n                  .___ _

Note: If a large population of repetitive standard type calculations are identified during the review process, S&L may request the NRC to approve an appropriate sampling in lieu of a 100% review of these repetitive calculations, The request shall be submitted with a sufficient technical basis for why a sample is justified based on safety significance and the                            ;
overall ICAVP process. Alternatively, for identical supports, S&L may perform a detailed review of the calculation for the support with the highest load.= For the other identical supports, S&L will only verify the analr.J load is consistent with the stress analysis.
: b. An upper tier drawing review including P& ids, electrical schematics, electrical single line drawings, instrument loop diagrams and logic diagrams to verify the system design is capable -
of performing the functional requirements described in the design and licensing bases and to verify the drawings are consistent with the design process documents.
: c.      A component review to verify consistency between the licensing and design bases documents and the design output documents such as, component specifications, system calculations, and vendor -
component drawings.
: d.      A review of hazards resulting from postulated pipe breaks in the selected systems including pipe whip, jet impingement, missiles and flooding; This review will verify that the effects of these hazards on adjacent safety systems have been included in the hazards analysis.
In addition, the SRG will evaluate the components of the selected systems to verify they are capable of performing station blackout

been effective and if the NU change processes are efective. The programmatic reviews will be performed in accordance with PI MP3 04 l'                            Licennee Initiated Corrective Actions l
As part ofits Configuration Management Program (CMP), NU has performed a vertical slice review of safety significant systems and has identified degraded or non-conforming conditions. For each of these degraded or non-conforming conditions NU is initiating corrective actions.
  ,                            Additionally, NU has implemented corrective actions for design deficiencies identified by the architect engineer before initial operation (EADCR's). The programmatic review will assess the adequacy of these conective actions. This review will be conducted for corrective actions associated with the syste is included in the scope of the ICAVP vertical '
slice system reviews, and for a represetative sample of corrective actions associated with the other NU completed CMP vertical slice systems.
The NU CMP findings / corrective action documents will be obtained both for the systems in the scope of the ICAVP vertical slice system review and for systems outside the ICAVP vertical slice system review.
A checklist will be prepared for the review of corrective actions. Using the checklist, the PRG Verifier will assess the corrective actions for adequacy of the following:
: a.      Root cause determination - the extent to which plant processes and procedures are affected,
: b.      Extent of condition determination - the extent to which ciber systems, structures or components are affected.
: c.      Plant restart is the corrective action required prior to restart?

As part of the ICAVP system r: views, the SRG and the ORG will assess the plant modifications made on the selected systems. This review will evaluate the effectiveness of the change processes involved in these modifications (i.e. if the resulting modification is found to be acceptable, it can be inferred that the process used in performing the modification is acceptable). In addition to this system review, specific process related reviews will also be performed by the PRG. The various change processes reviewed will include the following:

evaluation will be based on guidance provided in the following:
Reg Guide 1.33, Quality Assurance Program Requirements (Operation)
NRC Inspcction Manual INPO guidelines INPO 87 006, Report on Configuration Management in the Nuclear Industry-NEl guidelines The adequacy of NU's implementation of the change process pcocedure will also be evaluated, Since the system review wih assess the technical adequacy of the change, the programmatic review is intended to evaluate only the procedural adequacy of the change The evaluation will determine if the current procedure is being followed, that the required checklists are being accurately and ccmpletely filled in, and that all other documentation is complete and accurate. This evaluation shall be performed for the changes made to the selected systems using the current proceduas. If a suitable sample of these changes for a particular process is not captured in the system reviews, a suitable sample outside the ICAVP systems will be reviewed for both process implementation and technical adequacy.
In addition to the process and implementation reviews noted above, a review of select past changes on a plant-wide basis will also be made. For each of the change processes not generally associated with modifications, a sample of changes made during each five-year interval following receipt of OL will be reviewed for their technical adequacy. The changes generally will be selected from various systems other than the selected systems in order to maximize plant coverage. This review will assure that these past changes did not compromise the unit's design or licensing basis. The
                        " process specific questions" in checklist CK MP3-04-02 ir conjunction with applicable checklists from the SRG and ORG will be used to evaluate the technical adequacy of the changes.

l The DR will be signed by the VT member and forwarded to the VT Group Lead.
The VT Group Lead will review each DR with the VT meml-r for technical adequacy, completeness, and whether that specific is>ue has already been addressed by another DR or by an existing NU corrective action document. The DR could be retumed to the VT member for additional information or investigation; or it could be accepted and signed by the VT Group Lead; or it could be determined to be not valid. For any DR's determined to be not valid, the justification for this decision will be documented on the DR and the DR will be signed by the VT member and the VT Group Lead. If valid the VT Group Lead will forward the DR to the VT Manager.
The VT Manager will review each DR with the Group 1, cads for technical adequacy, completeness, and whether that specific issue has already been addressed by another DR or by an existing NU corrective action document.
The DR could be returned to the VT member for additional information or investigation; or it could be accepted and signed by tt VT Manager; or it could be determined to be not valid. For any DR's dc. ermined to be not valid, the justification for this decision will be documented on the DR and the DR will be signed by the VT member, VT Group Lead and VT Manager.

They will review the DR's for extent of the condition to confirm that the VT looked deep enough into the issue to ensure that the problem is fully I
scoped; they may make recommendations to the VT to look for similar conditions in other areas or systems. The IRC may request that the VT member obta!n additional Information; they could accept the DR as written, whereupon the IRC Chairman would sign the DR and return it to the VT
                                      . Manager, or the IRC may conclude the DR is not valid, if the VT member,
                                                                                                                                          ~
VT Group Lead, and the VT Manager agree with the conclusion that the '
DR ls not valid based on additional information, those justifications shall be documented on the DR and signed by the VT member, VT Group Lead, and the VT Manager.
All DR's will be transmitted to the NRC, NEAC, and NU when the above process is completed. The DR's will be transmitted in accordance with the                                        >
approved protocol. Since an important part of this project is to keep the public informed of the status and results, in addition to expected monthly meetings with the public, all DR's which are sent to NU and the NRC will be posted on the Internet World Wide Web approximately 48 hours after their submittal to the NRC/NEAC/NU.
4.9        Review NU Resolution to Verification Team Findings As shown in Exhibit 3 the handling of NU's proposed resolution of the VT fmdings will follow a similar process as the generation of the sindings except that IRC review of resolutions for significance Level 4 DRs is not -                                      ,
required. The resolution will be posted on the Internet Bulletin Board when received and will be submitted to the VT member who initiated the DR, the VT Group Lead and the VT Manager. If the proposed resolution
'-                                      for Level 1,2 or 3 DRs is determined acceptable, it is forwarded to the IRC for their review. Level 4 DRs do not require IRC review. If both the VT Team and the IRC (where applicable) find the NU resolution of the DR to be adequate, NU, the NEAC and the NRC will be notified by the method established in the protocol. At this point the acceptance of the NU
,.                                      resolutions to the findings will be posted on the Internet bulletin board                                        '
established for public access, if NU's resolution to the finding is not considered adequate by the VT member, VT management, or the IRC (for                                            ,'
the Level 1,2 or 3 DRs only), it will be returned to NU with a written explanation and bases for why the team did not consider it to be adequate.                                      ,

It is expected that NU would reconsider the information and resubmit it to the VT. Meetings between
                                      - NU and the_VT may be required to reach an understanding and resolution of particular issues. These meetings would be requestod and held in accordance with the established protocol.
i 5.0      SYSTEM SELECTION CRITERIA At the public meetings on September 24,1996, the NRC indicated that they would l                              select the systems for review rather than S&L. They also stated at those meetings l                              that the NRC would decide on the number of systems to be selected for review.
As input to the NRC staff, S&L recommendations on the number and selection of the systems for review are provided below.
l l,                              Sargent & Lundy's system selection criteria are based on NRC Inspection Manual I
Chapter 2535, Design Verification Program, modiflat to be appropriate to this situation of an operating unit. These criteria would be applied to the list of approximately 20 systems for which the NU line organintion and the NU oversight organintion will have completed their resiew also.
: 1)    The systems should be in the top quartile of risk significant or safety related
/
systems.-
: 2)      The systems should involve a full cross section of engineering disciplines with internal and external organintional interfhces, such as NSSS supplier, component vendor, and engineering senice organlution.
3)-    The concept and implementation of the design should not be limited to the NSSS supplier or another single component supplier.
: 4)      The systems should be generally repesentative of the safety related features of other systems.
                              -5)-    The systems should be reasonably complex, requiring multiple operating modes.
6)_    The systems should have multiple, non trivial modifications performed on it
                                      - since initial licensing, preferable by different design organintions.

With the likely selection of four systems, it is not necessary that every system meet y                            all of the above criteria. However, each system should meet as many of the criteria; as possible and each of the criteria should be met by st least two of the selected systems. The system selection may of course also be weighed more heavily to concentrate on specific known problem issues at Millstone Unit 3.
6.0      PROJECT DELIVERABLES
      ,            _      . Deliverables for this project will include a fmal report which describes the scope.of the ICAVP, the methodology used, the results of the review and the conclusions regarding the adequacy of the confguration management program and the
                            - corrective action program at Millstone Unit 3. Exhibit 4 of this audit plan presents an outline of the final report.
7.0      PROJECT TEAM The current project team members are identified on the project roster included
                            - herein as Exhibit 5. The project organization chart is included herein as Exhibit 1.
Changes or additions to the project team will be communicated to the NRC in accordance with PI MP3 08, when applicable, and will not require a revision to the audit plan. The compilation of Project Team position descriptions, personnel resumes, and conflict ofinterest statements is provided in Appendix A to this -
Audit Plan.
The selection of personnel for the ICAVP was based on their qualifications to perform the assigned reviews, their financial and technical independence from the
                            . Unit being reviewed, and NRC acceptance of the personnel. Substitution of
                            . existing personnc! on the team may be required to add expertise or manpower to =
fully investigate issues which are identified during the course of the program. A specific procedure (PI MP3 08) has been written to govern the substitution and addition of perwnnel to the r roject team. NRC notification and approval is required.

' 3.2 ' Verification Team-The VT is the core of the ciganization and is the group that does the actual review of the design and licensing bases and the effectiveness of the NU corrective actions. The VT is organized lato four functional groups. Each subgroup will be headed by a Lead engineer and will be responsible for a portion of the overall verification program. There will be a System Review -

Group (SRG), a Programmatic Review Group (PRG), an Operations and

_n ___ Maintenance land_ Testing Review Group (ORG), and an Accident

~ ~~~~~ ~ ~

Mitigation Systems Group (ARG).

The VT has been organized functionally in accordance with the review processes instead of by traditional engineering disciplines. However,' this is not to imply a strict compartmentahzed group strudure or review process.

I It will function as a single project team with significant cross utilization of L personnel among groups. It is expected that SRG and ORG personnel will I: ' perform review functions associated with the ARG and PRG In addition, there will be significant interfacing among the team members and the

Review Group Leads. Periodic full project team meetings will bJ conducted by the VT Manager in addition to periodic review group _

meetings conducted by the Leads. During the review and discrepancy resolution process, it is expected that the VT Manager will have daily briefings with the VT leads to discuss potential findings, share lessons learned, and discuss other project issues; Teamwork and frequent communications is a fundamental attribute for the conduct of the ICAVP and will be facilitated by the location of nearly all of the Chicago office project team members on the same floor of Sargent & Lundy's (S&L) offices.

The SRG will perform the in-depth review of the selected systems. This group will review the current system output documents and analysis to verify conformance with the design and licensing bases. The SRG will also review design modifications to the selected systems made since receipt of -

the OL, focusing on the validity of the design process, idemification e system interface requirements, potential synergistic effects of the modifications, and appropriate design document controls.

The SRG will also be responsible for verifying that the current, as-built condition of the plant matches the current design output documents. This task includes physical and functional walkdowns of the selected systems (6) l

  • Issuing FinalReport

- Note: : The intent of this review is to review only those systems for which NU's

- CMP process has been completed. . Accordingly, if during the conduct of.

' S&L's review, it becomes necessary to review items related to systems for which the NU CMP process has not been completed, a " place-holder" shall be utilized to discontinue that portion of S&L's review until such time that NU completes the CMP process for that system. Place-holders shall not be -

communicated outside of S&L.

4.1 Defining System Boundaries The systems to be included in the scope of the ICAVP program will be defined by the Nuclear Regulatory Commission. At the beginning of the

- system ruiew process, a meeting will be held with the NRC, Nuclear Energy Advisory Council (NEAC) and NU to finalize the boundaries of the selected systems and interfacing systems. In general, the systems boundary will be limited to the safety related portion of the selected systems. S&L's

- review for the vertical slice system will address interfaces with the selected systems as follows:

c.4.3 * ' System Reviews ~--- ----- ---

The vertical slice system reviews will be' performed by the SRG in -

accordance with PI-MP3-02 and 03, System reviews will focus on two !

objectives,1) to verify the system design elements being reviewed are technically adequate and consistent with the licensing and design bases (PI-

. MP3-02) and 2) to' verify the modifications implemented aAer receipt of the operating license are technically adequate and that configuration control of '

design documents was maintained (PI-MP3-03).

The first step of the process is to review the licensing and design bases documentation to identify the functional, design, performance, operational and testing requirements of the system. These requirements will be .

individually tabulated on a system requirements checklist by the SRG, The ORG will review the licensing and design basis documentation to identify

~the system coerating, maintenance and testing requirements. The ORG will

- also use'the system requirements checklist to tabulate their requirements.

The system requirements checklist will be independently verified prior to its use by the SRG and ORG as the bases for verifying design conformance to the design and licensing bases. Discrepancies between the design and licensin; bases documentation identified during the development of the system requirements checklist will be processed as discrepancy reports in accordance with Subsection 4.8.

Following the development of the system requirements checklists, the SRG -

will perform the four reviews described below. The purpose of these reviews is to verify the current system design is capable of the functional

. and performance requirements identified in the design and licensing basis documentation and to ensure consistency between the various design output documents and design process documents. Verification that current system operating, maintenance and testing practices and that current configuration is in accordance with the design and licensing basis (11) l m

documentation will be performed per sections 4.5 and 4.4, respectively.

These four reviews include:

a. . A review of design process documents to verify the technical adequacy of each document and its conformance to the design and licensing bases. This review will include mechanical, electrical, .

I&C, and structural calculations, piping analysis and equipment -

EQ/SQ reports. The design process document conclusions and/or Hm --_ - ._--- . assumptions will be verified against actual operating data,.where n .___ _

available.

Note: If a large population of repetitive standard type calculations are identified during the review process, S&L may request the NRC to approve an appropriate sampling in lieu of a 100% review of these repetitive calculations, The request shall be submitted with a sufficient technical basis for why a sample is justified based on safety significance and the  ;

overall ICAVP process. Alternatively, for identical supports, S&L may perform a detailed review of the calculation for the support with the highest load.= For the other identical supports, S&L will only verify the analr.J load is consistent with the stress analysis.

b. An upper tier drawing review including P& ids, electrical schematics, electrical single line drawings, instrument loop diagrams and logic diagrams to verify the system design is capable -

of performing the functional requirements described in the design and licensing bases and to verify the drawings are consistent with the design process documents.

c. A component review to verify consistency between the licensing and design bases documents and the design output documents such as, component specifications, system calculations, and vendor -

component drawings.

d. A review of hazards resulting from postulated pipe breaks in the selected systems including pipe whip, jet impingement, missiles and flooding; This review will verify that the effects of these hazards on adjacent safety systems have been included in the hazards analysis.

In addition, the SRG will evaluate the components of the selected systems to verify they are capable of performing station blackout

4.7 Etagrammatic Reviews l

! The programmatic reviews will be conducted by the PRO on a horizontal bases (across systems) for the purpose of determining if the actions taken

by Northeast Utilities (NU)!o conect previously identified problems have l

been effective and if the NU change processes are efective. The programmatic reviews will be performed in accordance with PI MP3 04 l' Licennee Initiated Corrective Actions l

As part ofits Configuration Management Program (CMP), NU has performed a vertical slice review of safety significant systems and has identified degraded or non-conforming conditions. For each of these degraded or non-conforming conditions NU is initiating corrective actions.

, Additionally, NU has implemented corrective actions for design deficiencies identified by the architect engineer before initial operation (EADCR's). The programmatic review will assess the adequacy of these conective actions. This review will be conducted for corrective actions associated with the syste is included in the scope of the ICAVP vertical '

slice system reviews, and for a represetative sample of corrective actions associated with the other NU completed CMP vertical slice systems.

The NU CMP findings / corrective action documents will be obtained both for the systems in the scope of the ICAVP vertical slice system review and for systems outside the ICAVP vertical slice system review.

A checklist will be prepared for the review of corrective actions. Using the checklist, the PRG Verifier will assess the corrective actions for adequacy of the following:

a. Root cause determination - the extent to which plant processes and procedures are affected,
b. Extent of condition determination - the extent to which ciber systems, structures or components are affected.
c. Plant restart is the corrective action required prior to restart?

d. Content is the corrective action adequate in resoMng the issue?

In addition to the review of corrective actions, the acceptability of the implemontation of certain corrective actions will also be evalusted.

Channe Procesg3 l NU's current plant change processes will be reviewed for both their l- ~ adequacy with respect to industry standards and for the effectiveness by which they are being implemented. Both design change processes and procedure change processes will be included in this review.

As part of the ICAVP system r: views, the SRG and the ORG will assess the plant modifications made on the selected systems. This review will evaluate the effectiveness of the change processes involved in these modifications (i.e. if the resulting modification is found to be acceptable, it can be inferred that the process used in performing the modification is acceptable). In addition to this system review, specific process related reviews will also be performed by the PRG. The various change processes reviewed will include the following:

'"" lCAVP Audit Plan Northeast Utilities Millstone Unit 3 , Revision 5 l setpoint changes NUC DCM Chapter 3 The current MP3 procedure for the processes listed above will be evaluated for its content and completeness. This evaluation will determine if the procedure exercises adequate controls on the change process and invokes appropriate interface reviews to assure the plant design bases and configuration is maintained consistent with the licensing bases. The -

evaluation will be based on guidance provided in the following:

Reg Guide 1.33, Quality Assurance Program Requirements (Operation)

NRC Inspcction Manual INPO guidelines INPO 87 006, Report on Configuration Management in the Nuclear Industry-NEl guidelines The adequacy of NU's implementation of the change process pcocedure will also be evaluated, Since the system review wih assess the technical adequacy of the change, the programmatic review is intended to evaluate only the procedural adequacy of the change The evaluation will determine if the current procedure is being followed, that the required checklists are being accurately and ccmpletely filled in, and that all other documentation is complete and accurate. This evaluation shall be performed for the changes made to the selected systems using the current proceduas. If a suitable sample of these changes for a particular process is not captured in the system reviews, a suitable sample outside the ICAVP systems will be reviewed for both process implementation and technical adequacy.

In addition to the process and implementation reviews noted above, a review of select past changes on a plant-wide basis will also be made. For each of the change processes not generally associated with modifications, a sample of changes made during each five-year interval following receipt of OL will be reviewed for their technical adequacy. The changes generally will be selected from various systems other than the selected systems in order to maximize plant coverage. This review will assure that these past changes did not compromise the unit's design or licensing basis. The

" process specific questions" in checklist CK MP3-04-02 ir conjunction with applicable checklists from the SRG and ORG will be used to evaluate the technical adequacy of the changes.

Northeast Utilities "~""*[j " " ICAVP Audit Plan Millstone Unit 3 f Revision 5 l 4.8 Processing Verification Team Findinas t When a member of the VT Identifies a discrepancy which does not appear to meet the requirements, he shall initiate a discrepancy report (DR) per Pl.

MP311. Exhibit 3 of this Audit Plan depicts the DR process. A discrepancy le . condition, such as an error, omission or oversight which prevents consistency among the physical configuration and information sources (e.g. documentation and databases), design basis and/or regulatory

= requirements. Examples of discrepe.t conditions are a disagreement between the system design bases and the FSAR, the as built configuration of a piping system and the piping analysis, or a change to maintenance procedures, whkh should have been made due to a plant modification, but was not. The DR will document the discrepant conditior and the documents or walkdown reports that were reviewed to arrive at that conclusion. Significance Levels I through 4 will be assigned to each DR by the Initiator. See PI MP3 11 for definition of Significance Levels.

Other technical and administrative items will be included on the DR form to help track, trend and analyze the results of the verification program.

l The DR will be signed by the VT member and forwarded to the VT Group Lead.

The VT Group Lead will review each DR with the VT meml-r for technical adequacy, completeness, and whether that specific is>ue has already been addressed by another DR or by an existing NU corrective action document. The DR could be retumed to the VT member for additional information or investigation; or it could be accepted and signed by the VT Group Lead; or it could be determined to be not valid. For any DR's determined to be not valid, the justification for this decision will be documented on the DR and the DR will be signed by the VT member and the VT Group Lead. If valid the VT Group Lead will forward the DR to the VT Manager.

The VT Manager will review each DR with the Group 1, cads for technical adequacy, completeness, and whether that specific issue has already been addressed by another DR or by an existing NU corrective action document.

The DR could be returned to the VT member for additional information or investigation; or it could be accepted and signed by tt VT Manager; or it could be determined to be not valid. For any DR's dc. ermined to be not valid, the justification for this decision will be documented on the DR and the DR will be signed by the VT member, VT Group Lead and VT Manager.

Northeast Utilities Millstone Unit 3 / ICAVP Audit Revision 5 Plan l The VT Manager will submit accepted DR's_to the IRC for their review.

They will review the DR's for extent of the condition to confirm that the VT looked deep enough into the issue to ensure that the problem is fully I

scoped; they may make recommendations to the VT to look for similar conditions in other areas or systems. The IRC may request that the VT member obta!n additional Information; they could accept the DR as written, whereupon the IRC Chairman would sign the DR and return it to the VT

VT Group Lead, and the VT Manager agree with the conclusion that the '

DR ls not valid based on additional information, those justifications shall be documented on the DR and signed by the VT member, VT Group Lead, and the VT Manager.

All DR's will be transmitted to the NRC, NEAC, and NU when the above process is completed. The DR's will be transmitted in accordance with the >

approved protocol. Since an important part of this project is to keep the public informed of the status and results, in addition to expected monthly meetings with the public, all DR's which are sent to NU and the NRC will be posted on the Internet World Wide Web approximately 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after their submittal to the NRC/NEAC/NU.

4.9 Review NU Resolution to Verification Team Findings As shown in Exhibit 3 the handling of NU's proposed resolution of the VT fmdings will follow a similar process as the generation of the sindings except that IRC review of resolutions for significance Level 4 DRs is not - ,

required. The resolution will be posted on the Internet Bulletin Board when received and will be submitted to the VT member who initiated the DR, the VT Group Lead and the VT Manager. If the proposed resolution

'- for Level 1,2 or 3 DRs is determined acceptable, it is forwarded to the IRC for their review. Level 4 DRs do not require IRC review. If both the VT Team and the IRC (where applicable) find the NU resolution of the DR to be adequate, NU, the NEAC and the NRC will be notified by the method established in the protocol. At this point the acceptance of the NU

,. resolutions to the findings will be posted on the Internet bulletin board '

established for public access, if NU's resolution to the finding is not considered adequate by the VT member, VT management, or the IRC (for ,'

the Level 1,2 or 3 DRs only), it will be returned to NU with a written explanation and bases for why the team did not consider it to be adequate. ,

It is expected that NU would reconsider the information and resubmit it to the VT. Meetings between

- NU and the_VT may be required to reach an understanding and resolution of particular issues. These meetings would be requestod and held in accordance with the established protocol.

i 5.0 SYSTEM SELECTION CRITERIA At the public meetings on September 24,1996, the NRC indicated that they would l select the systems for review rather than S&L. They also stated at those meetings l that the NRC would decide on the number of systems to be selected for review.

As input to the NRC staff, S&L recommendations on the number and selection of the systems for review are provided below.

l l, Sargent & Lundy's system selection criteria are based on NRC Inspection Manual I

Chapter 2535, Design Verification Program, modiflat to be appropriate to this situation of an operating unit. These criteria would be applied to the list of approximately 20 systems for which the NU line organintion and the NU oversight organintion will have completed their resiew also.

1) The systems should be in the top quartile of risk significant or safety related

/

systems.-

2) The systems should involve a full cross section of engineering disciplines with internal and external organintional interfhces, such as NSSS supplier, component vendor, and engineering senice organlution.

3)- The concept and implementation of the design should not be limited to the NSSS supplier or another single component supplier.

4) The systems should be generally repesentative of the safety related features of other systems.

-5)- The systems should be reasonably complex, requiring multiple operating modes.

6)_ The systems should have multiple, non trivial modifications performed on it

- since initial licensing, preferable by different design organintions.

Northeast Utilities

" "' ICAVP Audit Plan Millstone Unit 3 7 Revision 5 l l

With the likely selection of four systems, it is not necessary that every system meet y all of the above criteria. However, each system should meet as many of the criteria; as possible and each of the criteria should be met by st least two of the selected systems. The system selection may of course also be weighed more heavily to concentrate on specific known problem issues at Millstone Unit 3.

6.0 PROJECT DELIVERABLES

, _ . Deliverables for this project will include a fmal report which describes the scope.of the ICAVP, the methodology used, the results of the review and the conclusions regarding the adequacy of the confguration management program and the
