Purpose

The purpose of this report is to document Region III review of the piping

material traceability issue at Braidwood. In addition, this report documents

.

the actions taken to assure that the Braidwood Material Tracec',ility Verifica-

tion Program (MTV) was properly carried out, and to document the review and

evaluation of the " Report on Material Traceability Verification at Braidwoed",

dated November 1985, submitted by Conzonwealth Edison Company (CECO).

Background

A special Region III team inspection, conducted in June, July, August and

October of 1983 and during January and February of 1984, resulted in an

unresolved item concerning verification of correct heat number traceability

for piping and piping components. Specifically, it was determined that

Phillips Getschow Company (PGCo) had not been performing documented inspections

for correct material usage of piping and piping components at the time of

installation and a few instances were identified where material traceability

could not be readily verified. At the time NRC Inspection Report No. 50-456/

83-09; 50-457/83-09 was issued, the exact extent and significance of the

progrannatic deficiencies were unknown; therefore, this issue was made an

unresolved item. As detailed in the CECO response to the inspection report,

two actions were taken. The first action was to modify the piping material

control and installation procedures to provide documentation of material

traceability verification at the point of installation. This action tends

to minimize the possibility of recurrence of traceability deficiencies. The

second action was to initiate the MTV program. The MTV program contains

the following basic elements:

1. A material verification field walkdown on 100% of piping installed prior

to the procedure change.

2. A Quality Control verification of the field verified heat numbers against

the heat numbers in the original stores request.

3. A Quality Control verification to show that the installed items complied

with the design specification.

4. A Quality Control review of the " stores request" for items which do not

have physical identification.

In addition to the concern related to material verification at point of

installation, there was a related concern dealing with specific examples of

failure to follow the applicable procedures in this area. The MTV Program

was also structured to identify these items. . Also, the MTV Program was

independently reviewed and audited by the National Board of Boiler and

Pressure Vessel Inspectors National Board. The Illinois State Division of

Boiler and Pressure Vessel Safety also reviewed the program. Both

organizations found the program acceptable.

.

Conclusions

Based upon the Region III inspections ~and the review of " Report on Material

Traceability Verification at Braidwood," dated November 1985, it is concluded

that:

1. The MTV Program was sufficient to determine the traceability of the items

in question.

2. The MTV procedures and work instructions were implemented properly.

3. All items without the ASME Code required traceability have been removed

from the plant.

4. A number of installed items did not comply with applicable CECO or PGCo

procedures.

5. The original material control system delineated in the PGCo QA manual

met the requirements of the ASME Boiler and Pressure Vessel Code (ASME

B&PV),Section III.

6. The physical and chemical tests performed on the items removed (due to

lack of traceability) from the plant demonstrate that in fact that the

mdterial installed was the correct material and could have performed its

safety function.

7. Review of documentation indicates that all of the installed items could

have performed their respective safety function.

8. All installed items now have the ASME B&PV Code required traceability;

therefore, concerns relative to future 10 CFR Part 21 notificaticas are

resolved.

It is concluded that Ceco has taken adequate corrective action co resolve

specific instances of failure to follow material control procedures. Also,

the results as delineated in the Ceco " Report on Material Traceability

Verification at Braidwood" demonstrate the extent and significance of

implementation deficiencies found in this area.

2. Licensee Action on Previous Unresolved Items

(Closed) Unresolved Items (456/83-09-04(a); 457/83-09-04(a): This item was

classified as unresolved until the completion of the MTV program. This

report documents the NRC review of the pertinent issues and activities.

a. ASME Code and Appendix B Traceability Requirements

The.ASME B&PV Code gives no detailed information either on the

specific nature of material control systems or on the type of

Quality Control inspections required. The portion of the ASME B&PV

Code,Section III, which directly addresses this issue states:

6

r

.

"NA-4441 Establishment and Maintenance of Identification and Control

Measures:

Measures shall be established for identification and control of

material and items, including partially fabricated assemblies.

These measures shall assure that identification is maintained

either on the item or records traceable to the item throughout

manufacture or installation. These measures shall be designed

to prevent the use of incorrect or defective items, and items ,

which have not received the required examinations, tests, or

inspections."

The language of NA-4441 closely parallels Criterion VIII of 10 CFR 50,

Appendix B, which states, in part:

"These measures shall assure that identification of the item is

maintained by heat number, part number, serial number, or other

appropriate means, either on the item or on records traceable to

the item."

The intent of the material control system is to prevent the

installation of incorrect or defective items. NA-4441 allows a

control system which utilizes records traceable to the item. The

PGCo stores request system, as delineated in the QA manual, complied

with both the ASME B&PV Code,Section III, and 10 CFR 50, Appendix

B, Criterion VIII, prior to identification of the unresolved item.

When properly applied, this material control system provided a

record traceable to the item as required. The discrepancies in the

traceability of actual piping and piping components were the result

of failure to properly implement the stores request system.

b. Review of MTV Procedures

Activities performed under the MTV program were controlled by two

procedures: PGCo Procedure QCP-B31, Revision 4, " Material

Traceability Verification," and PGCo Work Instruction PGWI-17,

Revision 3, "QCT Review of MTV Program." The procedures contain

five major requirements as follows:

(1) 100% field walkdown for subject piping.

(2) All material identification marking recorded.

(3) Field gathered data compareo to stores request for item.

(4) Field gathered data compared to certified material test reports

(CMTR) for correct material specification, type, grade, class,

size, and schedule.

(5) Items found not traceable per stores request or otherwise

discrepant identified as nonconforming, and a nonconformance

report generated for each item.

7

i~

-

.

PGCo Procedure QCP-831 and Work Instruction PGWI-17 contain an

acceptable method for determining the traceability of installed

piping and piping components.

In addition, the NRC inspector reviewed PGCo Procedure QCP-B31.1,

Revision 1, " Untraceable Material Sampling Program." The purpose

of thi.* procedure is control of untraceable items and control and

storage of items removed from the plant. This procedure provides

an acceptable method for controlling these activities.

c. Nonconformance Board

The MTV program found 792 items to be in nonconformance with

applicable procedural requirements. The disposition of these NCR's

were provided by consensus of a nonconformance board consisting of

representatives of CECO, Sargent and Lundy Engineers (S&L),

PGCo, the Authorized Ir.spection Agency (AIA), and generally a member

of the National Board Audit Team. The NRC inspector attended the

disposition of a number of nonconforming items.

The NCRs discussed while the NRC inspector was in attendance are as

follows:

NCR 2301

NCR 2230

NCR 2183 (Item Removed)

NCR 2179

NCR 3595

NCR 3669

NCR 3729

The disposition of these NCRs was acceptable.

The NRC inspector independently reviewed the NCR package i?sted below:

NCR 3720

NCR 3301

NCF. 3326

NCR 3161

NCR 3068

NCR 3046

.

The information contained in the NCR packages complied-with procedure ,

requirements and the dispositions of the individual items were

acceptable.

Of the 792 nonconforming items, it was determined that 647 items,

while in nonconformance with PGCo and Ceco procedural requiremerits,

were in compliance with the traceability requirements of the ASME

Code (Braidwood procedural traceability requirements. exceeded those

of the-ASME Code). The remaining 145 items, listed below, were-

removed from the piping systems and replaced with traceable material:

d. Stores Request Review

One of the original concerns relative to piping material was the

viability of the PGCo " stores request" system as an effective

material control system. To further develop assurance concerning

the implementation of the system, the NRC inspector performed a

detailed review on the documentation associated with 30 items whose

traceability was established by the " stores request" document per

the original procedure. The details of this inspection are contained

in NRC Inspection Report No. 50-456/85043; 50-457/85042. Summarizing

the results, "None of the documents reviewed contradicted the

licensee's conclusions and in a majority of cases, independent

information, other than the stores request was on file in the

documentation packages which supported the licensee's conclusion."

Members of the National Board Audit Team reviewed documentation

associated with 50 installed items whose traceability was established

based on stores request documents only. The results of their review

are contained in the National Board Supplementary Report dated

September 26, 1985, and addressed to Cordell Reed, Vice President,

Ceco (" Material Traceability Verification at Braidwood", November

1985, Appendix A), and states "The audit confirmed the integrity of

the stores request system."

.e. Thickness Measurement of Installed Items

As discussed in NRC Inspection Report No. 50-456/85050; 50-457/85048,

' independent thickness measurements, using an ultrasonic digital

thickness measuring device, were taken on six piping systems which

contained MTV items. These measurements were taken to confirm that

the schedule of the installed piping (wall thickness) complied with-

the design specification and agreed with the information used in the

MTV program. Measurements were taken on portions of the following

piping systems:

ID004AB'- Diesel Fuel Oil

ICCD9AB - Component Cooling Water

ICC97AB - Component Cooling Water

ISX17AB - Essential Cooling Water

ICCD8AB - Component Cooling Water

ID063A - Diesel Fuel Oil

All'of the measurements taken confirmed the schedule of the installed i

'

piping and also confirmed the acceptability of the information that

was developed by CECO. In addition, the independent measurements

closely agreed with the measurements taken by CECO.

f. Selection of Samples

At a point in time near the completion of the MTV, CECO decided to

perform tests on the piping removed from the plant due to lack of

traceability. The purpose of these tests was to-demonstrate that

the untraceable material was in fact, the correct material and

therefore the lack of traceability did not impact the ability of :

the affected s All of the' items which H

were removed (ystems to function properly.except for 3 items mistakenly los1

subjected to an analysis which determined the chemical composition

of the material.' Sixteen of the removed items were subjected to

physical tests which demonstrated that they conformed to the

strength requirements of the applicable specification. Two

considerations determined which items were appropriate for physical

tests. The'first consideration was size; approximately 90 of the

removed items were too small for physical testing. The second

consideration was'the' presence of manufacturers' markings. Approxi-

mately 30 items, with clear manufacturers' marks identifying mate' rial l

type, did not have the same degree of uncertainty associated with l

their physical properties, and therefore were not appropriate for

physical testing.

The group of items tested contained both carbon steel and stainless

steel and both large bore items and small bore items. In addition, I

the only untraceable section of piping'in an ASME Class I system us i

tested (NCR 4756 Item 68). A portion of the testing was witnessed by

a NRC inspector.

< ;

..

All of the items subjected to the chemical testing conformed to the

applicable ASME/ ASTM specifications. All of the items subjected to

the physical testing for strength conformed to the applicable

ASME/ ASTM specification.

The final report produced by Taussig Associates, Report No. 64188-1,

" Chemical and Tension Testing of Samples Associated with the MTV

Program," was reviewed. A number of the chemical composition results

were reviewed by the NRC inspector for compliance with ASME B&PV

Code requirements for chemical composition. A number of the

physical (strength) results were also reviewed by the NRC inspector

for compliance with ASME B&PV Code requirements for strength. ~All

results demonstrated compliance with applicable code strength and

composition requirements.

g. Review of Reports

As part of the inspections associated with the MTV program, CECO's

Report " Material Traceability verification at Braidwood," the National

Board's letter of September 26, 1985,.and the Office of the Illinois

State Fire Marshall, Division of Boiler and Pressure Vessel Safety

letter of June 21, 1985,.were reviewed. Based on the NRC inspections

of the MTV program and the review of the Ceco's final ~ report, it has

been determined that the CECO final report is an accurate representation

of the activities conducted and their results. In addition, our

review of the National Board activities and our review of their letter

supports the National Board's general conclusions:

"The Phillips, Getschow quality assurance program, as written,

did provide the necessary controls to assure that the work

,

performed by PGCo at the CECO Braidwood Nuclear Power Station

! met the requirements of the ASME Code and the certified design

specification."

'

"As noted previously in the report, there were implementation

deviations from the PGCo quality assurance program's requirements."

"These deviations led to the generation of the MTV program and

the resulting revisions to the PGCo quality assurance program

and material control procedures."

i Duane R. Gallup, Superintendent of Boiler and Pres 9ure Vessel

Safety for the State of Illinois, suuported the MTV program in his

June 21, 1985 letter. Quoting the letter,

"I am satisfied that the corrective action program which

Commonwealth Edison Company (CECO) has undertaken will result

in assuring the piping systems at the Braidwood site will be

in compliance with the requirements of the ASME Code."

h. Safety Significance Evaluation

As part of the overall MTV program, a " safety significance"

evaluation, composed of calculations necessary to demonstrate

compliance with ASME B&PV Code strength requirements, was performed

for all the items which were nonconforming due to insufficient

traceability. A random sample of these noncomforming item

evaluations (listed below) was reviewed in detail:

NCR 2085

NCR 2183

NCR 2785

NCR 2873

NCR 2919

NCR 3027

NCR 3291

NCR 3350

NCR 3465

NCR 3553

NCR 4294

NCR 4756

NCR 4769

NCR 4873

NCR 5490

In addition, the Sargent and Lundy Report BRF-PMD-01 (November 13,

1985), " Design Significance Evaluation of Braidwood Material

Traceability Verification (MTV) Program Cut Out Items" was reviewed.

This report and the. disposition of these NCRs were acceptable.

~

In NRC Inspectio'n Report No. 50-456/83-09; 50-457/83-09, two items

were identified which did not have the required schedule of piping

installed. Because these items were replaced prior to the

initiation of the formal MTV program they were not included as

items in the MTV. program final report. Safety significance

evaluations were performed which found that the installed items

could have performed their safety function in compliance with the

ASME B&PV Code. The evaluations were reviewed and found acceptable.

i. . Inspection Conclusions

Based on the NRC inspections and reviews of the MTV program, the

following conclusions have been reached:

(1) The original material control system ~ contained in the PGCo QA

manual complied with the requirements of the ASME B&PV Code.

(2) There were a number of instances in which the proper procedures

were not followed. These are the 792 items identified in the

CECO final report as nonconforming. This is the basis for a

violation of 10 CFR 50 Appendix B, Criterion V. (456/85061-01;

456/85057-01).

.

(3) The specific instances of failure to follow procedures did not

appear to impact the ability of the systems to perform their

safety function.

(4) The MTV program was an effective method to determine the

traceability of the items in question.

(5) The MTV program was conducted in accordance with applicable

procedures.

(6) 145 Items lacking the required traceability have been removed

from the plant and replaced with items which have the required

traceability.

(7) It now appears, based on the results-of the MTV program,' that

the Material Control System originally employed by PGCo was

effective to the extent that no items were installed which

would have impacted the ability of the piping systems to

function properly.

3. Exit Interview

The Region III inspectors met with licensee representatives (denoted under

Paragraph 1) at the conclusion of the inspection on January 9, 1986. The

inspectors summarized the scope and findings of the inspection. The

licensee acknowledged this information. The inspector also discussed the

likely informational content of the inspection report with regard to

documents or processes reviewed during the inspection. The licensee did

not identify any such documents / processes as proprietary.
