Applicant Actions on Frevious Inspection Findings

a.

(0 pen) Open Item (445/3511-0-04): This item remains open pending the

review and assessmant of the dispositions relating to the 12

deviatir.g skewed welus in NF supports.

,

Further review with respect to the status of this item has resulted

in the NRC's identification of a violation.

During ERC's reinspection of skewed welds in Unit 1, unde size

.

conditions were identified and documented on B&R nonconformance

reports (NCRs) as early as June 1985.

CPSES Station Administration

Manual Procedure No. STA-405 requires that all documented

nonconformances, in which "use-as-is" dispositions are recommended,

be forwarded to TUGC0 Operations Results Engineering Group for review

to determine if as-built documentation changes are needed.

Further,

CPSES Nuclear Operations Engineering Manual Instruction No. N0E-201-5

requires that proposed drawing changes be submitted to Operations for

review, approval, and authorization to distribute the revised

drewing.

The NCRc associated with the undersize skewed welds are identified as

XI-2,

-3,

-4, -5,

-6, -7,

-8, -10 and -11.

The applicable pipe

support drawings were resised by TUGC0 Nuclear Engineering (TNE) to

reflect the undersize weld conditions.

Recalculations were performed

to support the use of the welds without rework or repairs. While the

NCRs were not formally dispositioned, this action, in effect,

provided a "use-as-is" disposition.

However, TUGC0 Operations did

not review and approve the drawing revisions.

In fact, in most cases

TUGC0 Operations did not initiate their own NCR to address these

conditions until after INE had' revised and distributed the drawings.

As of the end of this report period, TUGC0 Operations NCRs have not

been dispositioned.

The NRC inspector was informed by TUGC0

.

Operations personnel that their review has found a number of

'

mathematical errors in the TNE recalculations, thus precluding a

dispositioning of the TUGC0 NCRs.

!

The failure of TNE to acquire TUGC0 Operations review and approval

prior to initiating drawing revisions is a violation

(445/8514-V-03).

,

b.

(Closed) Open Item (445/8513-0-06):

Pecvisions for familiarizing QC

inspectors with changes in QC inspection procedures.

Details on this

subject are contained in paragraph 7.d of this appendix.

3.

Followup On Alleged Contractor Improprieties

The NRC inspector performed a followup inspection with respect to the

identification by a local newspaper of alleged contractor improprieties.

The inspection was_ performed to ascertain whether the alleged

improprictles, if substantiated, could adversely affect safety-related

components and systems.

NRC review of this subject revealed that the

i

,

alleged improprieties, which consisted of eight specific items, had been

.

reviewed by the TUGC0 Safeteam and by the TUSI Director of Coroorate

Security. NRC examination of the items, certain of which were

substantiated, resulted in a determination that there was no instance

whers any substantiated item had any impact with respect to safety-related

components or systems.

The NRC considers this item to be closed.

NRR and IE Audit / Inspection Activities

4.

NRR;

A site inspection was performed during October 10-11, 1985,

pertaining to civil / structural issues. Audits were performed on

October 25, 1985, at Ebasco and Stcne and Webster, New York,

pertaining, respectively, to cable tray / conduit supports and small

bore piping review.

A site audit was performed of homogeneity of

construction processes during October 9-10, 16-18, and 28-31, 1985.

b.

IE:

An inspection of Design Adequacy Review was initiated at TERA.

Bethesda, Maryland, during October 28 through Nover.ber 4,1985.

A

site inspection of QA program procedures was performed on

October 20-24, 1985.

,

Copies of reports for these activities will be placed in the Public

Document Room upon completion.

5.

CPRT Procedures and Instructions

a.

Implementaticn of ERC Procedures and Instructions

(1) Audit of_CPP-012 (QA/QC Interface with Constructor /TUGCO)

The TUGC0 interface consists of three systems used to request

equipment or services, copies of documents, or technical

information.

Each is handled by a differer,t process, as defined

in CPP-012.

'

(a) Written requests for equipment and services are used by the

QA/QC inspectors to recuest from TUGC0 or B&R any equipment

,

or services needed to perform an inspection.

These

requests are included in the completed inspection package.

-

An NRC inspection of CPP-012 implementation showed that the

requests for equipment and services were being processed in

accordance with CPP-012 requirements, with the exception

that the QA/QC Records Administrator was not controlling

these requests as required by Section 4.4.6 of the

procedure.

No logs or files were maintained by +.he QA/QC

Records Administrator.

This item is an NRC deviation

(445/8514-D-01). During this inspection, the NRC inspector

concluded from information provided by ERC personnel that a

log of requests was not being naintained by the QA/QC

Inspection Supervisor, as required by Section 5.1.3 of

CPP-012.

Subsequent to this report period, the NRC was

inforn:ed by ERC management that this understanding was

incorrect and that the required log was, in fact, being

maintained in accordance with CPP-012 requirements.

Followup inspection confirmed that the ERC clanagenent

information was correct.

It was ascertained, however,

during this followup inspection that verification package

numbers were being used to identify requests in the log.

This practice permits more than one request to have the

same identification number and is ccntrary to procedural

requirements for use of unique identification numbers.

TUGC0 has been requested by the transmittal letter for this

inspection report to include this subject in their response

to deviation 445/8514-D-01.

l

(b) Document requests are used to request copies of TUGC0 or

Cid documents required by the ERC inspectors.

Section 5.2.2

of CPP-012 requires that the QA/QC issue coordinators

maintain a file of these requests.

The files of two issue

coordinators were inspected by the NRC, and found to be

satisfactory.

No NRC deviations were identified.

(c) Technical information requests are prepared by a member of

the QA/QC Review Team when a request for clarification or

additional information is required.

These, after

supervisory approval, are sent to the responsible TUGC0

liaison engineer by the QA/QC Records Administrator, who

also log and files the requests.

The logged item is

closed and the request filed when the information arrives

from the TUGC0 liaison er.gineer.

Two specific requests

were traced t;y the HRC inspector through the Construction

Sampling Reinspection Engineering Group and Recoros

Administration, and found to have been satisfactorily

!

processed and routed.

No hRC deviations were identified.

(2) CPP-018(QA/QC Interface with the Design Adequacy ProgramJ

'

-

An NRC inspection confirmed that documents transmitted from ERC

,

to TERA for infermation only were transmitted by the QA/QC

.

Records' Administrator.

Documents requiring feedback from TERA

"

are logged and transmitted by the ERC Hardvare Isay s

Supervisor.

The TERA Design Adequacy Program Interface Coordinator receives

the ERC domments, distributes them and files one copy.

Items

'

requiring feedback to ERC are logged in and the date of reply is.

also logged. .The HRC inspector selected four documsats from the

~

.

ERC log and was able to satisfactorily trace them through the

~

ERC and TERA logging and filing systems.

No NRC deviat, ions ~were identifled.

- (3).CPP-010(PreparationofDeviationRNports)andCPP-016'(Safety

Significance Evaluations of Deviation Reports)

' Deviation Reports (DRs) are generated during thekardware and

'

documentation inspection process.

These DRs are' assessed <for

validity then forwarded for further processing to the Safety-

'

Significance Evaluation Group (SSEG) and'TUGCO.

.

1he NRC inspector confirmed that the process,(which is described

'

'in CPP.010 and CPP-016, is being'followed.

A sample of twenty

organization being surveyed.

The reports are maintained as

open items until'all recommendations are implemented.

At that

time, the report files are closed and transmitted to the Records

Inspection Reports on Butt Splices (ISAP No. I.a.2) and Butt Splice

Qualification (ISAP No. I.a.3)

Status of CPRT Activity

Phase II of ISAP No. I.a.2 has been completed with the following

findings:

(1) No undocumented butt splices were identified during the

inspection of 38 cabinets which were supposed to be free of

,

splices;

(2) A total of 603 butt splices were identified during the

inspection of 26 cabinets and 25 motor control centers, which

from documentation were supposed to contain 648 splices.

This

difference resulted because 149 of the documented splices were

not installed, but 104 undocumented splices were discovered;

(3) A total of 168 of the above 603 butt splices were found to be

unsatisfactory, either by physical inspection or as a result of

being undocumented;

(4) A total of 80 unsatisfactory butt splices were removed for

testing and replaced; and

(5) A review was performed of 341 irs which were applicable to 286

'

butt spliced cables. This review identified deficiencies in 294

irs; e.g., failure to identify which conductors were spliced,

and after the fact verification of a splice rather than the

required witness.

In addition to finding some unacceptable

splices during the Phase II inspections, some splices documented

in records were found to not be installed.

TUGC0 submitted a

report in accordance with 10 CFR Part 50.55(e) dated

September 26, 1985, concerning the identified deficiencies.

An

interim Corrective Action Report, CAR-050, has been issued.

Status of NRC Inspection Activity

installation is, complete and is undergoing review.

The report

describing the ' analytical evaluation of stresses and support load

changes has been issued by R. L. Cloud & Associates (RLCA) and has

t,een reviewed by TERA.

Review and revision of pipe procedures for

pipe erectior. and placement of temporary and permanent supports, as

well_as engineering significance of these procedures, is also

'

.

Status of NRC Inspection Activity

.

The RLCA report addressing the installation of main steam pipes has

been reviewed for adequacy with respect to the methods of analysis.

The review included supporting computer output, calculations, piping

models, and assumptions made.

During this review the following

conditions were noted:

-

(1) While the use of a "come-along"' for horizontal adjustment is

mentioned in Section 1.3, " Additional Background," it is not

addressed in the analytical portion of the report.

(2) The 18-inch bypass line is modelled in as a schedule 60 pipe,

but drawing FSM-00165 specifies a schedule 40 pipe.

Documentation was not available to substantiate that a schedule

60 pipe was used.

Even though the schedule 60 piping is

conservative as far as stress is concerned, it will have some

impact or, other conclusions made in the report such as vertical

displacements.

(3) Figure 3-12 in the analysis does not represent computer output

No. RLCA P142-1-551-018, in that the node numbers do not

correspond.

(4) The NRC TRT identified that sagging occurred during flushing

operations.

RLCA states that sagging occurred before flushing.

The date of the flushing should be established.

The above conditions constitute an unresolved item (445/8514-U-13).

No NRC violations or deviations were identified.

Material Traceability (ISAP No. VII.a.1)

'

' Status of CPRT Activity

<

'

The issue coordinator is receiving input from ISAP Nos. VII.c and

VII.b.3.

This information aids in the assessment of the overall

material traceability control systems.

Heat numbers on steel items

such as supports and piping are being checked as part )f the

reinspections to establish traceability.

Status of NRC Inspection Activity

The NRC inspector has reviewed ISAP No. VII.a.1.

This review found

that the overall material traceability control system was to be

evaluated for adequacy.

Preliminary results of ISAP No. VII.c

reinspections indicate that data on material traceability in areas

other than steel is not being compiled.

This lack of data could

adversely affect the assessment of the material traceability control

systems. This matter is considered to be an unresolved item

(445/8514-U-14).

No NRC violations or deviations were identified.

Housekeeping and System Cleanliness (ISAP No. VII.a.7)

Status of CPRT Activity

This ISAP addresses two specific TRT concerns and performs an

overview of the program on housekeeping and system cleanliness.

Eleven plant surveys conducted by TUGC0 and overviewed by ERC

inspectors have been completed.

The issue coordinator has reviewed

the procedural controls to de~cermine if requirements of

Criterion XIII of Appendix B to 10 CFR Part 50 and the FSAR are

included.

Inputs from ISAP Nos. II.c, V.b, VI.a, and recent

TUGC0/B&R audit reports, surveys, and other quality documents are

being reviewed to evaluate the effE;tiveness of the current program.

. Specific TRT concern on the number of chloride residue. swipes made on

the wall and bottom of the reactor vessel has beerr investigated.

These items were noted by TUGC0 and ERC personnel. . An independent

NRC resurvey of these areas found that the noted discrepant

conditions had been restored to requirements.

The NRC inspector reviewed the file for FP-55-08' to verify that the

eight chloride residue swipes had been taken for the reactor vessel

wall and bottom.

Valve Disassembly (ISAP No. VII.b.2)

Status of CPRT Activity

p

A second reinspection of seven Borg-Warner (8-W) valves was conducted

using B-W serial numbers for body and bonnet identification.

This

reinspection was necessitated by the fact that identification numbers

used in the initial reinspection were traceable to material heat

numbers, but were not necessarily unique to each valve bonnet or

body.

No DRs were issued as a result of the second reinspection.

All reinspections are now complete.

Of a total of four valid DRs

issued for this ISAP, three SSEs have been completed.

The fourth DR

(VALV-9-1) identifies a mismatch between the identification numbers

observed on the valve bonnet and that which is listed in the QA/QC

documentation package for the valve.

QA/QC documentation for the

actual installed bonnet has not been located to date.

A difference was identified by the SSE engineer between the

respective design temperature and pressure listed by G&H and those

listed by Westinghouse for the Chemical Volume Control system.

'

Specifically,theg&Hlinedesignationtableliststhedesign

temperature as 250 F and the design pressure as 300 psi, while the

i

correspondingWestinghousedgsigntemperatureandpressureare

listed, respectively, as 150 F and 150 psi.

Independent NRC inspections have also been performed

on five valves in the combined random and engineering samples.

The NRC inspector was informed by TUGC0 Field Mechanical Engineering

personnel that: (1) the previously described differences between G&H

and Westinghouse design conditions had also been identified by TUGCO,

'

and (2) a comparison of G&H and Westinghouse design conditions for

' mechanical equipment had been conducted by TUGC0 which resulted in

the identification of several. design pressure and temperature

differences.

The NRC inspector also noted that NCRs have.been written by TUGC0 for

several valves having temperature and/or pressure ratings listed on

the Code Data Log that are different from those listed in the G&H

line designation table.

It was not immediately apparent whether or

not the Westinghouse /G&H comparison study had also identified these

differences.

Verification of the adequate resolution of differences identified in

"

the Westinghouse /G&H comparison study and those identified in NCRs is

During the above documentation reviews the NRC inspectors

observed the following deficiencies:

(a) Lighting conduit EAB1-1 was physically reinspected by ERC

and witnessed by NRC.

ERC subsequently discarded this item

from the sample of conduit population,.because not enough

attributes were accessible for inspection.

The NRC

inspector performed an independent documentation review of

this field witnessed activity and noted that the TUGC0

electrical inspector, who signed the final irs E-1-0027419

and E-1-0024951 for conduit EAB1-1, was not certified to

Procedure QI-QP-11.3-25.

TUGC0 Procedures CP-QP-2.1 and

to perform their assigned tasks.

The lack of certification

of the ThiC0 electrical inspector performing the inspection

,

-

of record for conduit EAB1-1 is a violation

(445/8514-V-04).

'

(b)

ISAP No. VII.c requires original documentation review for

attributes deemed to be inaccessible.

A portion of conduit

C13616037 was found to be inaccessible during reinspection

as a result of being covered with separation barrier

,

material (SBM).

There was no evidence in ERC's

'

,

Verification Package No. R-E-CDUT-064 that a check was made

for attributes which were not accessible due to SBM

'

installation.

This is an NRC deviation (445/8514-0-02).

(c) QI-009, Revision 0, " Document Review of Conduit /R-E-CDUT,"

requires the reviewer to record the SBM IR and/or latest

-construction operation traveler number at the bottom of the

checklist.

The checklist for conduit C13016037 in

Verification Package No. R-E-CDUT-064 did not contain this

required documentation.

This item is an NRC deviation

(445/8514-0-03).

(d) QI-009, Revision 0, " Document Review of Conduit /R-E-CDUT,"

also requires the ERC inspector to verify that irs signed

by electrical inspectors were " dated after their date of

certification and prior to their date of expiration."

ERC Verification Package No. R-E-CDUT-070 for conduit

C14R13047 failed to indicate that the ERC inspector

observed that the electrical inspector signing IR-E-46087

was not certified to QI-QP-11.3-23 on the date of

inspection.

This item is an NRC deviation (445/8514-0-03).

(e) During this review, the NRC inspector observed that TUGC0

inspection procedures (i.e., QI-QP-11.3-23 and

QI-QP-11.3-23.11) for conduit did not require inspection

for separation between approximately September 1979 and

November 1983.

The NRC inspector was informed that a

decision was made to inspsct conduit for separation af ter

construction completion, on a room-by-room basis.

The NRC

inspector was also informed that this activity is

prescribed in QI-QP-11.3-29 and that documentary evidence

is available in the Permanent Plant Records Vault (PPRV),

filed by area or room " turn over" numbers.

This item is considered unresolved pending review of this

documentation (445/8514-U-17).

(f) The NRC inspector observed during documentation review of

conduit C13016037 that the ERC inspector did not review

construction operation traveler EE83-0997-8904 for other

than inspector certification and correct QI reference on

the traveler,

it was also noted that construction

operation travelers EE84-10324-8904, EE84-10505-8904,,and

'EE85-11255-8904, in response to Item Removal Notices (IRNs)

for SBM removal and replacement, were not reviewed to

ascertain the certification status of any additional

inspectors that had been used to those that signed the

applicable irs.

This item is unresolved pending NRC review

of construction operation traveler documentation in the

PPRV (445/8514-U-18).

(g) The NRC inspector reviewed documentation for six other

conduits. ERC reviews were scheduled but had not been

completed. The results of these review:; will be reported in

a subsequent report after comparison of NRC review results

with the completed ERC results. This is an open item

(445/0514-0-10).

(h) The NRC inspector observed that documentation reviews for

lighting conduits could not be performed by ERC because

QI-009, Revision 0, does not address the relevant QIs;

i.e., QI-QP-11.3-25 and QI-QP-11.3-9.

This is an open item

pending the issuance of new instructions or a subsequent

revision to QI-009 (445/8514-0-11).

Status of CPRT Activity

ERC has completed 20 reinspections and 19 documentation reviews of

sampled electrical equipment installations as of Octouer 30,

This reinspection total is lower than the number (i.e.,21)

reported in NRC Inspection Report No. 50-445/85-13, 50-446/85-09 as

being performed by September 20, 1985.

The difference arose as a

result of revision to QI-010 and institution of re-review of

for the document reviewers.

QI-013, Revision 4, " Documentation.

Review for Instrumentation Equip R-E-ININ," did not list

specific attributes to be verified during documentation

review, but rather required verification of installation in

accordance with one or more of a listing of TUGC0 procedures.

Applicable procedure revisions were not defined.

The

number of inaccessible and/or nonrecreatable attributes may

vary between different revisions of a procedure.

As an

example, Revision 1 of QI-QP-11.8-8 adds to Revision 0

requirements an inspection checklist addressing verification

of: (i) color codes for nuts; (ii) flange face cleanliness;

(iii) gasket size, rating, and material type; (iv) nuts

being tightened in a diametrically opposite sequence; (v)

studs being the sane length; (vi) proper alignment and

fitup of flange and gasket; and (vii) sufficient gasket

compression.

The absence of instructions to the document

reviewer on procedure revisions to be used can thus result

in insufficient guidance with respect to inaccessible and

nonrecreatable attributes.

This is an NRC deviation

(445/8514-D-02).

'

~(b)

In the review of Verification Package No. R-E-INIh-060, the

NRC inspector noted that the original inspection was

performed by a TUGC0 inspector whose certification to

QI-QP-11.8-7 could not be verified.

TUGC0 is currently

investigating the missing certification documents.

This

matter is an unresolved item (445/8514-U-19).

(5) Independent reinspections were performed by the NRC inspector on

Verification Package Nos. I-E-ININ-04 and I-E-ININ-026, with the

following results:

I-E-ININ-04:

Required bend radius verification was not

performed by ERC inspectors.

I-E-ININ-026:

ERC inspectors did not idantify that: (a)

required color coding on six sections was missing, (b) incorrect

slope was present, and (c) an incorrect air gap condition was

present.

.

The failure of ERC inspectors to identify the above conditions

is an NRC deviation (445/8514-D-04).

(4) For all witnessed reinspections, the ERC inspector did not

measure duct gage thickness which was a required attribute.

The

NRC inspector was informed by ERC that such measurements were

not possible due to inaccessibility to the inside of the duct.

HVAC Equipment Installation

Ststus of CPRT Act*vity

,

As of October 25, 1985, reinspe-tions have been completed for 38 of

89 random items in the HVAC equ v.t.ent installation samples.

The

reinspections have identified conditions which necessitated the

issuance of 68 DRs, none of which have been currently vr.lidated.

Reinspection was on hold for approximately one week, pending a change

notice.to QI-023, Revision O.

This change notice involved changes in

. the following areas: (1) the method of verifying companion flange

bolt tightness and gasket compression, (2) inclusion of verification

of full thread engagement between companion flange bolts and nuts,

(3) companion flange bolt centerline to flange edge distance

requirements, and (4) the mtthod of certification of gravity damper

counterweighc balance.

Previously reinspected items will require a

followup reinspection, where apslicable, as a result of this

revision.

The NRC inspector was informed by the ?opulation en0 neer that the

i

HVAC equipment installation plan will be revised to incorporate two

distinct populations, each requiring a minimum sample size of 60.

Large Bore Piping Configuration

Status of CPRT Activity

As of October 25, 1985, reinspection was complete for 65 of the 99

random sample large bore piping configuration items. The

reinspections identified conditions which resulted in the issuance of

34 DRs,18 of which, to date, have been validated and are undergoitig

an evaluation by ERC for safety significance.

Tiie NRC inspector was informed by the population engineer that the

population items list is currently being revised to exclude all items

not having an "N-5" designation on the piping isometric drawings.

One exception will be certain safety-related piping in Unit 1 that

4

has been exempted from "NA" code stamping requirements.

The NRC inspector was informed that the above' described revision to

the population items list is required in order to ensure that all

CPRT reinspection items had been previously inspected and accepted by

construction QC.

Approximately 24 previously reinspected items will

be excluded from the reinspection samples as a result of this

i

revision.

Deviations have involved incorrect flow direction orientation of an

orifice plate, insufficient clearance with adjacent piping and

equipment, a different part number on a valve to that shown on the

isometric drawing, linear and location measurement differences,

insufficient sleeve clearances, missing code data plate, and flow

direction not marked on the valve.

ERC has completed 73 reinspections of piping system bolted

joints /naterials as of October 26, 1985.

However, on eight of these

reinspe.ctions the attribute dealing with flange rating could not be

inspected because the flange was painted.

The paint will be scraped

Large Bore Pipe Supports - Rigid

Status of CPRT Activity

Reinspection / verification of pipe support installations by ERC is

approximately 94% complete.

A total of 151 deviations have been

identified of which 98 have been determined to be valid.

The

remainder are currently being reviewed for validity.

Status of NRC Inspection Activity

(1) The NRC inspector performed independent inspections on pipe

support Verification Package Nos. I-S-LBSR-013-and -023, in

order to assess the adequacy of the ERC reinspections.

The ERC

-reinspection of pipe support Verification Package No.

.

I-S-LBSR-013 was determined to be adequate, accurate, and

complete. However, during the independent inspection of

I-S-LBSR-023, one deviation from a commitment was identified

with respect to failure to identify discrepant dimensions.

Paragraph 5.3.4.c in QI-027 states with respect to dimensional

tolerances not shown on design drawings, " Component Member-

Length +/- 1/2 inch." The Bill of Material on Revisicn 2 of

'

,

drawing No. CT-1-097-402-C52R lists item No. 4 (2 pieces) as

, ~

being 7 3/4 inches long.

Independent NRC inspection determined

.

the actual length dimensions to be, respectively, 6'5/8 inches

and 6 1/2 inches, both of.which are under the minimum indicated

,e.

dimension of 7 1/4 inches (445/8514-0-04).

(2) During inspection of the installation of box frame supports,

j

which are a part of the Unit 1 containment spray system, t' e NRC

'

inspector observed that clearances exist between the botton: of

the pipe and the pipe support, and in some cases no clearance

exists between the top of the pipe and pipe support.

The TUGC0

Engineering as-built piping verification supervisor was

contacted about the conflict between the as-built drawings for

these supports and the actual field configuration.

The TUGC0

Engineering supervisor stated that their as-built piping

,

configuration program, TNE-DC-24-1, satisfies the requirements

of NRC Bulletin 79-14 and that the as-built configuration

,

!.

complied with installation tolerances.

The conditions

identified above increase loading on adjacent pipe supports and

increase stresses on the piping system.

The conditions listed

,

'

above are being referred to NRR for consideration when

determining the accuracy and adequacy of Stone and Webster-

,

Engineering Corporation's stress analysis program for the

applicable design specific action plan.

A total of 217 deviations have been

identified of which, to.date, 162 have been determined to be valid.

Status of NRC Inspection Activity

(1) The NRC inspector witnessed ERC's reinspection of Verification

Package No. I-S-LBSN-249 to verify compliance with QI-029.

During the inspection, ERC identified the following conditions

to the NRC inspector as subject to evaluation as potential

deviations: (a) component member lengths out of tolerance, (b)

undersize welds, and (c) missing locking devices.

Dispositions of the above items are an open item

(445/8514-0-26).

No NRC violations or deviations were identified.

(2) The NRC. inspector performed independent inspections on pipe

support Verification Package Nos. I-S-LBSN-014, -025, -035, and

-052, in order to assess the adequacy of the ERC reinspections.

This effort revealed that ERC had performed their reinspections

in accordance with the requirements of QI-029.

No NRC violations or deviations were identified.

The NRC inspector was informed by the population engineer that the

population items list'is currently being revised.to exclude all items

not having an "N-5" designation on the piping isometric drawings.

One exception will be certain safety related piping in Unit 1 that

has been exempted from "NA" code stamping requirements.

'

The NRC inspector was informed that the above described revision to

the population items list is required in order to ensure that all

~

,

CPRT reinspection items included those which had been previously

'

inspected and accepted by construction QC,

Approximately 20

previously reinspected items will be excluded from the reinspection

samples as a result of this revision.

Deviations have involved out of tolerance linear and location

measurements, incorrect valve flow direction orientation, inadequate

clearances with adjacent piping and equipment, and the part number on

a valve differing from that on the isometric drawing.

Status of NRC Inspection Activity

(1) ERC methods.and related documents used in establishing the

population items list were reviewed for population

inclusiveness.

Completed SSE reports are currently being

reviewed by the NRC inspector.
