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 | |||

. | |||
. | |||
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. | |||
I | |||
i | |||

< ; | |||
. | |||
. | |||
. | |||
.. | |||
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). | |||
20 | |||
L | |||
( .- | |||
_ | |||
- | |||
. | |||
. | |||
(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. | |||

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
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
NCR 3025

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.
