TVA EMPLOYEE CONCERNS SPECIAL PROGRAM REPORT NUMBER:
40300 FRONT MATTER REV:
3 PAGE i OF viii Preface This subcategory report is one of a series of reports prepared for the Employee Concerns Special Program (ECSP) of the Tennessee Valley Authority (TVA).
The ECSP and the organization which carried out the program, the Employee Concerns Task Group (ECTG), were established by TVA's Manager of Nuclear Power to evaluate and report on those Office of Nuclear Power (ONP) employee concerns filed before February 1, 1986, Concerns filed after that date are handled by the ongoing ONP Employee Concerns Program (ECP).
The ECSP addressed over 5800 employee concerns.
Each of the concerns was a
formal, written description of a circumstance or circumstances that an employee thought was unsafe, unjust, inefficient, or inappropriate.
The mission of the Employee Concerns Special Program was to thoroughly investigate all issues presented in the concerns and to report the results of those investigations in a form accessible to ONP employees, the
- NRC, and the general public.
The results of these investigations are communicated by four levels of'CSP reports:
- element, subcategory,
- category, and final.
Element reports, the lowest reporting level, will be published only for those concerns directly affecting'the restart of Sequoyah Nuclear Plant's reactor unit 2.
An element consists of one or more closely related issues.
An issue is a potential problem identified by ECTG during the-evaluation process as having been raised in one or more concerns.
For efficient handling, what appeared to be similar concerns were grouped into elements early in the program, but issue definitions emerged from the evaluation process itself.
Consequently, some elements did include only one issue, but often the ECTG evaluation found more than one issue per element.
Subcategory reports summarize the evaluation of a number of elements.
- However, the subcategory report does more than collect element level evaluations.
The subcategory level overview of element findings leads to an integration of information that cannot take place at the element level.
This integration of information reveals the extent to which problems overlap more than one element and will therefore require corrective action for underlying causes not fully apparent at the element level.
To make the subcategory reports easier to understand, three items have been placed at the front of each report:
a preface, a glossary of the terminology unique to ECSP reports, and a list of acronyms.
Additionally, at the end of each subcategory report will be a Subcategory Summary Table that includes the concern numbers; identifies other subcategories that share a concern; designates nuclear safety-related, safety significant, or non-safety related concerns; designates generic applicability; 'and briefly states each concern.
Either the Subcategory Summary Table or another attachment or a combination of the two will enable the reader to find the report section or sections in which the issue raised by the concern is evaluated.
TVA EMPLOYEE CONCERNS SPECIAL PROGRAM REPORT NUMBER:
40300 FRONT MATTER REV:
2 PAGE ii OF viii The subcategories are themselves summarized in a series of eight category reports.
Each category report reviews the major findings and collective significance of the subcategory reports in one of the following areas:
management and personnel relations industrial safety construction material control operations quality assurance/quality control welding engineering A separate report on employee concerns dealing with specific contentions of intimidation, harassment, and wrongdoing will be released by the TVA Office of the Inspector General.
Just as the subcategory reports integrate the information collected at the element level, the category reports integrate the information assembled in all the subcategory repor ts within the category, addressing particularly the underlying causes of those problems that run across more than one subcategory.
A final report will integrate and assess the information collected by all of the lower level reports prepared for the
- ECSP, including the inspector General's report.
For more detail on the methods by which ECTG employee concerns were evaluated and reported, consult the Tennessee Valley Authority Employee Concerns Task Group Program Manual.
The Manual spells out the program's objectives,
- scope, organization, and responsibilities.
It also specifies the procedures that were followed in the investigation, reporting, and closeout of the issues raised by employee concerns.

SUMMARY
MATERIAL CONTROL CATEGORY SUBCATEGORY REPORT 40300 "INSTALLATLON"
SUMMARY
OF THE ISSUES There are sixteen concerns in this subcategory.
The sixteen concerns were grouped into ten issues to facilitate effective evaluation of similar concerns.
These issues addressed
- 1) valves being subsLit.uted without revising drawings, 2) a valve on unit 1 pressurizer being cracked,
- 3) pipe fittings having low tensile strength,
- 4) pipe fittings not having NDE reports,
- 5) material from an uncertified vendor is installed in the steam generator blowdown system,
- 6) electrical cable issued from warehouse without vendor certification documentation,
- 7) scrapped material being installed in the plant,
- 8) Westinghouse material'eing received without proper documentation, 9) two different pipe sizes having the same heat
- number, nnd 10) structural steel was found to be laminated and steel with tho same heat number is installed in plant.
Three of the ten issues were found to be current problems during the evaluation.
One of the throe problems was caused by isolated error.
See attached summary table (page 1 of 5 thru 5 of 5).
MAJOR FINDINGS 1.
Valves have been replaced and/or substituted without drawing revision or design approval.
In some cases the impact on design baseline is not known.
Procedures were not in place to control this.
2.
Material was retrieved from the scrapyard and installed at Watts Bar Nuclear Plant (WBN).
All four nuclear plants had weak scrap and surplus material control programs.
COLLECTIVE SIGNIFICANCE OF MAJOR FINDINGS 1.
Because of the lack of procedural control for valve substitution or replacement at WBN, the design base line. for safety-related systems could be wffected.
This issue was also considered at SQN.
Because valve procurement practices for SQN (different than for WBN) would minimize this potential problem and because the inspection/installation documentation agreed with the as-constructed drawings, this issue was determined not to be a problem at SQN.
This issue dealt with a WBN specific concern.
2.
Safety-related items scrapped or not maintained in their proper storage environment can be degraded and could have the potential to degrade safety-related systems at WBN. However, the impact of the safety of the plant is minimized by the construction, preoperational, startup tests and surveillance and inspection programs in place.
Actual problems were identified only at WBN although scrap and surplus material control programs at other nuclear plants were weak.
1015T
CAUSES OF THE MAJOR FINDINGS The cause for both of the major problems was a lack of management attention and procedural control.
CORRECTIVE ACTION ON MAJOR FINDINGS 1.
NCR 6773, for unit 2, was initiated to identify all substituted/replaced safety-related valves and to revise inspection procedures to ensure valves installed agree with design drawings.
Reference CATD number 40300-WBN-02 SCR number WBN WBP 8725 has been initiated to document this problem and to control corrective action.
Corrective action will require a
review of unit 1 safety-related valves to ensure that the installed valves satisfy applicable design requirements and are adequately reflected in the associated design and as-constructed documents.
DNE will provide a walkdown procedure to verify actual valve installation, to determine what valves have been replaced or substituted.,
to verify if the design baseline has been affected and that documentation adequately reflects the as-constructed condition.
Appropriate corrective action will be taken to resolve all problems identified.
DNE will provide requirements to be implemented in appropriate
and Maintenance procedures to effectively control and verify valve replacements and substitutions to maintain the design baseline..
- DNE, DNC, and Maintenance will issue the subject procedures and conduct appropriate personnel training to implement this program.
Reference CATD number 40300-WBN-01 (unit 1).
2.
Nonconformance reports have been initiated at WBN requiring engineering evaluation of items retrieved from the scrapyard and installed in the plant.
WBN and SQN are revising procedures to control material.
They are purging field storage areas to minimize the availability of questionable material.
Procedures will be put in place to adequately control material.
Scrapyards are being locked and controlled.
The corporate issue corrective action plan will further strengthen controls at all four plants.
Reference CATD numbers 40300-NPS-01, 40300-WBN-05 (unit,2),
40300-WBN-06 (unit 1),
and 40307-SQN-01.

OF 62 1.0 CHARACTERIZATION OF ISSUES 1.1 Introduction There are sixteen concerns in the subcategory Installation.
All the concerns in this subcategory deal with installed material that is questionable, The concerns addressed by this report were placed in ten groups.
These groups are referred to here after as issues for the purpose of evaluation.
These issues are described in greater detail below in section 1,2.
1.2 Descri tion of Issues (As originally perceived) 1.2.1 Valve Substitution (1 concern)
EX-85-181-001 Valves have been substituted (from what the drawing requires) without the Bill of Materials showing the change.
There is no other documentation to show the change.
1.2.2 Valve Cracked (1 concern)
PH-85-035-002 At WBN there is a 3-inch valve located at the top of the unit 1 pressurizer in system 68 (Reactor Coolant) with a crack or lamination in the valve body that runs into the weld area.
1.2.3 Fittings (Heat Code M-157)
(1 concern)
IN-85-012-X02 Fittings with Heat Code M-157 have a tensile strength reported on the CMTR that is below the minimum and some of these fittings are installed.
1.2.4 Fittings (Without NDE Reports).
(1 concern)
IN-86-282-005 There are approximately 2,000 1 1/2-inch or 2-inch ASME class 1, 90-degree elbows that do not have NDE reports with the material certification documentation.
1.2.5 Material From Uncertified Vendors (1 concern)
IN-85-086-001 Noncode material may still exist in the Steam Generator Blowdown system.

SUMMARY
2.1 Summar of Issues The perceived problem expressed in the concerns in this subcategory report is that some of the materials installed at SQN and WBN may not be capable of performing their intended function safely or may not have acceptable documentation.
2.2 Summar of Evaluation Process The employee concerns addressed by this subcategory were evaluated in accordance with revision 1 of the Evaluation Plan for Construction and Material Control Categories.
Since each element was evaluated as a independent entity, the specific evaluation methodology varied due to the nature of each element.
In general, the evaluation methodology consisted of the following steps:
TVA EMPLOYEE CONCERNS SPECIAL PROGRAM REPORT NUMBER:
40300 REVISION NUMBER:
3 PAGE 10 OF 62 a.
Obtained additional information on the specific concerns where available [i.e. reviewed expurgated files and contacted QTC].
b.
Interviewed personnel knowledgable of the perceived problems addressed by this subcategory report.
c.
Reviewed documentation, applicable site procedures and upper tier requirements related to,the perceived problems.
d.
Performed field observations as required to determine existing conditions.
2.3 Summar of Findin s
Of the ten elements addressed by this report, three were found to be factual and required corrective action.
Three of the elements addressed by this report were evaluated at TVA nuclear plants other than WBN.
The remainder of the elements addressed specific issues of hardware at WBN and the evaluation findings determined that these issues were not generic to other TVA nuclear plants.
l Below is a summary of the findings for each of the ten elements addressed in this subcategory.
2.3.1 Valve Substitution This was determined to be a Class D issue at WBN and This concern was WBN-specific and found to be factual and a
problem at WBN.
At WBN, valves have been substituted for the valves required on the drawing without the required document changes being implemented.
This was evaluated at SQN and found not to be factual.
- However, a
CATD (CATD 40301-SQN-01) was issued for SQN since it was found that the work control procedures did not reference the procedure to be used for material substitution.
It should be noted that this report addresses only the portion of this concern that is underlined on Attachment A of this report.
(CATDs 40300-WBN-01 and 40300-WBN-02)
TVA EMPLOYEE CONCERNS SPECIAL PROGRAM REPORT NUMBER:
40300 REVISION NUMBER:
3 PAGE 11 OF 62 2.3.2 Valve Cracked This was found to be a Class A issue at WBN and a Class E issue at S N.
This concern was specific to WBN and found not to be factual.
There is not a crack or lamination in one of the 3-inch valves at the top of the pressurizer at WBN unit 1 and the valves that were previously installed in this location and are still in use do not contain a crack or lamination.
Because one of the valves involved was transfered to SQN from WBN, the valve at SQN was evaluated and found not to contain a crack or lamination.
- However, due to the restrictive criteria for inspection of these
- valves, proper evaluation of the indication in the subject valve can not be performed at SQN and this needs, to be addressed.
(CATD-40302-SQN-Ol) 2.3.3 Fittings (Heat Code M-157)
This was found to be a Class D issue.
This concern was specific to WBN and found to be factual and a problem.
The tensile strength on this WBN CMTR was determined to be below the minimum.
'A retest had been performed on this material that shows it meets the requirements, but this retest documentation was not available at WBN.
Corrective action for this concern is implemented by NCR 6771.
(CATD-40300-WBN-03) 2.3.4 Fittings (Without NDE Reports)
This was found to be a Class B issue.
This concern was specific to WBN and found to be factual but not a problem because it is not a requirement for NDE reports to be with the material certification documentation.
The documentation on this material assures that it meets the code and purchasing contract requirements.
TVA EMPLOYEE CONCERNS SPECIAL PROGRAM REPORT NUMBER'0300 REVISION NUMBER:
3 PAGE 12 OF 62 2.3.5 Material From Uncertified Vendors This was found to be a Class B issue.
This concern was specific to WBN and found to be factual but not a problem.
This problem had been identified by NCR GEN MEB 8301 before this concern was issued.
All of the subject material was evaluated and was allowed to remain installed if in nonsafety-related low pressure areas; otherwise, it was replaced.
It should be noted that Material Control Subcategory Report 40200 addresses the aspects of this concern as related to purchasing.
It should be noted that this report addresses only the portion of this concern that is underlined on Attachment A of this report.
2.3.6 Cable This was found to be a Class B issue.
This concern was specific to WBN and was found to be factual but not a problem.
The vendor cerLification documentation for cable was not required to be onsite.
Permanent documents were received by TVA Inspection and Testing (IST) Branch.
Procedures were in place to control cable released for installation and evidence exists that cable not meeting the requirements was nonconformed., It was also found'hat the Watts Bar 'Environmental Qualification Project was" reviewing all safety-related cables installed in a harsh environment and the completion of this effort would assure this cable was qualified for installations 2.3.7 Scrapped Material (TVA Usage-Excess,
- Surplus, Leftover, Etc.)
This was found to be a Class D issue at WBN and a Class E
Issue at S
This issue was comprised of six WBN-specific concerns and one SQN-specific concern and was found to be factual and a
problem at WBN.'o TVA procedures for WBN, were in place to prevent usable material from being scrapped and retrieved from scrap collection areas for use in QA or safety-related applications.
Corrective actions have been initiated at WBN and are discussed in section 4.7.
Based on the fact that the
TVA EMPLOYEE CONCERNS SPECIAL PROGRAM REPORT NUMBER:
40300 REVISION NUMBER:
3 PAGE 13 OF 62 existing program at WBN did not provide adequate control of material and specific items were identified as having been scrapped and retrieved for installation, WBN DNC has initiated two NCRs (NCR 6837 and 6839) for unit 2 addressing this condition.
These NCRs address any past conditions that may have resulted from an inadequate program for scrap material.
This concern was evaluated at
- SQN, BFN, and BLN and no specific items were identified as having been scrapped and retrieved for installation; but the programs in place to control material were found to be in need of improvement.
TVA has no written or definitive programmatic criteria in place to establish a method of determining when an item should be placed in scrap and how this material should be controlled to prevent its possible use.
It should be noted that the subcategory "Material Waste and Availability As Related to Management and Personnel,"
(Report 71100) addresses the non-QA aspect of this issue.
The findings in Report 71100 agree with this report. It should be noted that, this report addresses only the portion of concern WI-85-091-014 that is underlined on Attachment A of this report (CATDs 40300-WBN-04, 40300 WBN-OS, 40307-SQN-01 and 40300-NPS-01).
2.3.8 Westinghouse Material This was found to be a Class A issue.
This perceived problem was WBN-specific and found not to be factual.
Although Westinghouse material was delivered to WBN without the required documentation in the subject timeframe (before June 1982) the DNC engineers responsible for this material initiated NCRs when this occurred.
These NCRs required receipt of the required documentation and this had been completed.
2.3.9 Pipe This was found to be a Class B issue.
This concern was WBN-specific and found to be factual but not a problem.
The fact that 3/4-inch pipe has the same heat number as 1/2-inch pipe does not constitute a problem.
This occurs because both sizes of the pipe were manufactured from the same bulk material with a singular heat number.
This does not violate any site procedure or upper-tier requirement.
TVA EMPLOYEE CONCERNS SPECIAL PROGRAM REPORT NUMBER:
40300 REVISION NUMBER:
3 PAGE 14 OF 62 Heat numbers are verified at weld fitup inspection.
The adequacy of this program is addressed in the Material Control Subcategory Report 40700 "Procedural Control."
2.3.10 Beam This was found to be a Class B issue.
This concern was WBN-specific and found to be factual but not a problem.
A section of beam was found that contained laminations and material with this same heat number was allowed to remain installed.
- However, when this section of beam was found, an NCR (NCR 5942) was written to identify and correct this condition.'NE performed an evaluation of this material and determined that only the pieces of material where the laminations interfere with the constructability were not acceptable.
It should be noted that laminations in material is addressed in a broader scope in Material Control Subcategory Report 40600 "Quality of Materials."
2.4 Summar of Collective Si nificance Of the ten issues addressed in this report, two were found not to be valid situations.
Five of the issues were valid situations but did not represent a problem (two had been previously identified and corrective action completed and three did not violate any commitment or requirement).
Three of the issues addressed in this report were found to be problems but one of the these was an isolated case.
With the specific exception identified, TVA had programs in place to assure that material used in plant installations meets quality requirements and personnel involved in the work processes would identify and correct problems found with material, 2.4.1 Management Effectiveness The subcategory findings for some issues indicated a failure to implement a review of procedures to verify that upper-tier requirements and commitments would be implemented, a
failure to make personnel aware of what the actual requirements and commitments
- are, as well as ineffective communication.
TVA EMPLOYEE CONCERNS SPECIAL PROGRAM REPORT NUMBER:
40300 REVISION NUMBER:
3 PAGE 15 OF 62 2.4.2 Employee Effectiveness The subcategory findings for some issues indicate a lack of knowledge and understanding of procedures as well as upper-tier commitments and requirements.
This can be attributed to inadequate training of personnel caused by a lack of management awareness.
2.4.3 Technical Adequacy The subcategory findings in this report do point out areas in which technical effectiveness is suspect.
Incidences such as unauthorized valve substitution and lack of a program to control scrap material has caused the technical adequacy to become inadequate or questionable in those areas.
2.5 Summar of Causes Below is a summary of causes for these elements for which corrective action is required.
2.5.1 Valve Substitution Failure by DNE and DNC management to have adequate communication and implement a valve program that would be effective and meet commitments.
2.5.2 Valve Cracked (Side Issue)
The problem identified as a side issue at SQN (see 2.3') was caused by a failure to implement criteria for determining the acceptability of the subject valves.
2.5.3 Fittings (Heat Code M-157)
Based upon the fact that these CMTRs were reviewed by a TVA engineer as well as an Authorized Nuclear Inspector, the apparent cause for this problem was isolated human error.
2.5.4 Scrapped Material Failure by management to implement a program to control
- material, to issue TVA procedures for controlling material at MBN, and to have adequate procedures at

3 PAGE 16 OF 62 2,6 Summar of Corrective Action Taken Below is a summary of corrective actions already initiated for the eloments found to be substantiated and side issues identified in this report.
2.6.1 Valve Substitution DNC has generated NCR 6773 to address this problem in unit 2 at WBN.
This NCR requires DNC to supply a list of all valves that have been substituted to DNE for review to determine if the substituted valves are acceptable.
CATD 40300-WBN-02 The Office of Nuclear Power (ONP) is addressing this problem for WBN unit 1.
SCR WBN WBP 8725 has boen initiated to document this problem and control corrective action.
CATD 40300-WBN-01 The following was identified as a side issue.
SQN needs to address the fact that procedural control of work involving/controlling materials substitution is not cross-referenced between AI-ll, AI-19 and SQM 2 as recommended by GCTF Report EX-81-181-001, revision l.
Line response:
Since cross-referencing
~ever procedure used during the work process would be confusing and would not ensure any better compliance with requirements no procedure revision is required.
2.6.2 Valve Cracked The following was identified as a side issue.
SQN needs to obtain information to show that indications in the subject valves are a result of the valve construction, and this does not represent defects.
CATD 40302-S N-Ol A memorandum requesting vendor certification to the acceptability for use "as-is" has been initiated.

3 PAGE 28 OF 62 3.3 Justification of Evaluation Process The process used in this evaluation resulted in gaining as much knowledge about the perceived problems as possible, finding factual
- evidence, and documented conditions during the timeframe of the concern and what presently exists.
The items that still were not completely addressed after the above steps were taken were then examined by physical observation, a review of procedures, and/or interviews.
4.0 FINDINGS 4.1 Valve Substitution 4.1.1 Generic Applicability The issue in the subject concern addressed in the evaluation was site specific to WBN.
- However, the GCTF.evaluated this concern at SQN relative to the ONP program.
The related issue was evaluated at SQN to determine the adequacy of the GCTF report and if this issue was valid during construction.
Validation of the related concern was not established from the review, but work control procedures do not reference the procedure for material substitution.'.1.2 Plant-Specific Applicability
- 4. 1. 2. 1 WBN a.
The additional information obtained from QTC was that unit 2 system 15 (blowdown) was the area of concern.
b.
C ~
A review of the expurgated file revealed that the information found in step a.
was correct.
Reviewed WBNP-QCP-4.10-9 revision 7 and earlier revisions and found that at installation valve mark numbers were not verified by QC as being in accordance with the drawing.
Valves were verified as meeting the requirements supplied by project engineering for identification.
- d. It was concluded from the personnel interviewed that valve substitution was a
common practice, and the documentation in'ome cases was not
TVA EMPLOYEE CONCERNS SPECIAL PROGRAM REPORT NUMBER:
40300 REVISION NUMBER:
3 PAGE 29 OF 62 completed.
These substitutions were made by Project Engineering personnel based on a
notation on the Bill of Materials drawing that specified the valve "or equal." It was learned by interviews with DNE personnel that "or equal" was used on these drawings for procurement purposes.
e
~ It was learned by the drawings and documentation reviewed that valves had been substituted.
The mark number on the inspection record did not, in all cases, agree with the mark number shown on the piping drawing.
==
Conclusion:==
This was found Lo bo a Class D issue.
Valves have been substituted from what the drawing requires without appropriate documentation.
This has resulted in inaccurate "as constructed"
- drawings, the probability of having valves installed without the proper documentation for the specific
- service, and the possibility that some valves may not be suitable for service at their installed location.
4.1.2.2 SQN a.
This was found to be a Class E issue.
It was determined by reviewing TVA SQN GCTF report EX-85-181-001, revision 1, and related documents that the findings, conclusions, and recommendations were adequate.
SQN does have a
program in 'place to control valve substitutions.
b.
No additional investigations were found for the subject concern.
TVA EMPLOYEE CONCERNS SPECIAL PROGRAM REPORT NUMBER:
40300 REVISION NUMBER:
3 PAGE 30 OF 62
- c. It was learned by the interviews conducted that all safety-related valves at SQN received a
unique identifier and the program required a
FCR to be written for valve substitution.
(Note:
FCRs result in drawing revisions.)
- d. It was determined by reviewing the mechanisms used to control valve installation (inspection procedure, design drawing's and valve index) that the program used prevented improper valve installation.
This is based on the following:
The valve inspection procedure (SNP Inspection Instruction Number 42) required verification that the valve installed was the correct valve (per the drawing).
2.
The valve identifiers on the piping drawings were similar to the identifiers on the WBN piping drawings.
- However, safety-related valves for SQN were supplied by Westinghouse Electric Corporation and Westinghouse E-Spec 677473 gives an explanation of valve indices used to identify valves.
It was
- found, by reviewing this, that where valves were physically the same they were given the same Westinghouse identification number.
This in itself would prevent the problems found at WBN from occurring at SQN.
e
~ It was determined, by reviewing 30 piping
- drawings, that when valves were substituted at SQN the substitution was documented.
This is based on the fact that 6 of the drawings reviewed showed areas circled that indicated the drawing had been revised to change valve identifiers.
There was no indication on the other 24 drawings reviewed that valves had been substituted.

- f. It was found by reviewing construction valve installation inspection documentation for 200
.valves that valves were not substituted without the'requir'ed documentation during the construction phase of SQN.
The valve inspection documentations used can be found in the case file.
==
Conclusion:==
Based on the above the concern addressed in this element is not valid at SQN.
However a
CATO was issued for SQN since it was found that the work control procedures did not reference the procedure to be used for material substitution.
During the construction phase of SQN, the valve installation program maintained adequate control of valve substitution and the program currently used was found to be adequate.:
4.2 Valve Cracked 4.'2. 1 Generic Applicab ility The concern addressed by the evaluation of this issue was site-specific to WBN.
During the evaluation it was found that one of, the valves in question had been removed for repair and was now installed at SQN.
The evaluation revealed that none of the valves in question were cracked or had
.laminations therefore this concern was not valid at other TVA nuclear plants.
4.2.2 Plant-Specific Applicability 4.2.2.1 MBN a.
QTC provided no additional information on the subject concern.
b.
No additional information was obtained from the expurgated file for the subject concern.

- c. It was determined by reviewing the DNE drawings that the subject valve was one of four valves based on the description and location stated in the subject concern.
- d. It was found by personal observation that other 3-inch valves do not exist in the area described in the subject concern.
- e. It was determined by reviewing the documentation on the valves identified in the steps above:
- 1) valves, 2,
The vendor furnished documentation for the valves in question was complete,
- adequate, and indications of cracks or laminations could not be found.
3.
Problems had been identified on 2 of these valves (PORVs) in the past.
The valve seats were found to contain cracks.
This resulted in all of valves supplied to TVA for this application-at WBN and SQN being returned to the vendor for repair.
When the subject valves were returned they were not installed in the original locations.
This resulted in one of the original unit 1
WBN valves being installed in unit 2 at WBN and the other valve being installed at SQN.
Since no timeframe could be identified for the subject concern, all of the valves that had been installed at the subject location and were still in service required examination.
At WBN this required examination of five valves for cracks or laminations.

It was found, by the examinations conducted of the subject valves, thaL there were indications in the subject valves.
These could be mistaken for cracks or laminations but further examination and evaluation revealed that these indications were surface scratches or marks left by the manufacturing process of these valves.
It should be noted that Level II NDE inspectors performed the initial examination.
The additional examinations involved four Level III NDE inspectors (one TVA DNC Level III NDE, one TVA DNE Level III NDE, one Level III NDE from the manufacturer of three of the subject valves, and one Level III NDE from a contract NDE "company).
The initial examinations were visual examinations and the additional examinations included visual exams, penetrant test and radiography.
None of the Level III NDE personnel involved found evidence of a condition that would affect the safe operation of these valves or of a crack or lamination.
(Reference memorandums B48
'860718 003 and B45 '860703275)
Based on a review of element report MC-40302 and the subject case file, it was concluded that Target Rock Valve serial number 1983-3 was the only valve at SQN that required examination for cracks or laminations.
b.'pare Valve serial number 1985-10 was visually examined for cracks or laminations and none were found.
This valve was then placed in service replacing the subject valve (serial number 1983-3).
The subject valve received a visual inspection by a Level IZ.NDE inspector of the interior and exterior of the valve body, and no indication of cracks or laminations were found in the weld areas.
- However, there was an elliptical shaped indication on the interior surface of the outlet side of the valve body adjacent to the indicator tube.
This was further evaluated by a Level III NDE inspector.
and determined not to be a crack, but the

This valve is no longer installed).
The indication identified occurred in the valves that were examined at WBN and were evaluated and found not to be detrimental to the valves safe operation.
Work Requests (WRs) B-115224 and 115223 authorized this work and documented the inspections performed.
Conclusion This was found to be a Class A issue at WBN and a.
Class E issue at S
N ~
Based on the above and the information learned during the inspection of the other three Target Rock valves that were examined at WBN, the indications found in the subject valves were not in the weld area as stated in the concern, and these indications are inherent to the manufacturing process for these valves and not a crack or lamination.
Therefore, the concern is not factual.
Because of the restrictive criteria for inspection of these
- valves, the proper evaluation of the indication could not be performed at SQN. It is line management's responsibility to address this situations 4,3 Fittin s (Heat Code M-157) 4.3.1 Generic Applicability The concern addressed in this issue was site-specific to WBN.
Although this concern was found to be valid, the cause for this problem was found to be isolated human error.
Therefore, there is no reason to believe that this problem exists at other TVA nuclear plants, 4.3.2 Plant-Specific Applicability 4.3.2.1 WBN a.
QTC provided no additional information on the per ce ived problem.

No pertinent information was obtained by reviewing the expurgated file.
c.
The findings of NSRS report I-85-164-WBN, showed that a retest had been performed prior to the concern being expressed and the material was acceptable.
This report however, did not address the mechanism used to document the retest.
- d. It was determined by the interviews conducted that the retest of this material was not properly documented.
e.
A review of the documentation for the subject Heat Code revealed that the documentation was incomplete.
There was no indication in this documentation that a retest had been performed.
Additional documentation review revealed that CMTRs are reviewed for acceptability and the fact that this heat code did not have the required tensile strength on the CMTR was caused by isolated human error.
These CMTRs were reviewed by a TVA engineer and an Authorized Nuclear Inspector.
==
Conclusion:==
This was found to be a Class D issue.
This concern was factual and a problem.
The tensile strength on the CMTR was below the minimum and the retest performed had not been properly documented.
This needs to be addressed by line management.
4.4 Fittin s (Without NDE Re orts) 4.4.1 Generic Applicability The concern addressed in this issue was site-specific to WBN and during this evaluation there was no indication that this problem exist at other TVA nuclear plants.

- However, the ASME code of record for MBN (1971 through summer of 1973 addendum) and the contracts this material was purchased by do not require the NDE test reports to be included with the material certification documentation,
- d. It was concluded from the review of the ASME code that it is not a requirement for the NDE reports to be part of the material certification documentation for the subject material.
e.
Reviewed the piintout of Class 1, l-l/2-inch or 2-inch 90-degree elbows and the documentation for 18 for these heat numbers.
Zt was found that all of these heat numbers met the requirements of the ASME code of record for WBN and the purchasing contracts.
The CMTRs contained one of the following:
1.
NDE Reports'.
A statement that the material meets ASME Section III, Class 1 requirements.
3.
A TVA NDE report for upgraded material.
==
Conclusion:==
This was found to be a Class B issue This concern is factual but not a problem.
NDE reports are not available onsite for all the subject material; however, this is not a requirumonl. pf TVA Specification 1521 or Article NB-2000 of the ASME code of record for MBN.

4.5.2 Plant-Specific Applicability 4,5.2.1 WBN a.
The information provided by QTC related that the reference on the concern to System 32 was a
- mistake, the.concerned individual had been contacted; and System 15 (Steam Generator Blowdown) was the only system of concern.
b.
No pertinent information was obtained by reviewing the expurgated file.
c.
The review of ERT Investigation Report IN-85-086-001 and related documents revealed the following:
The perceived problem as stated on the concern did exist at WBN; however, NRC IE bulletin 83-06 which resulted in NCR GEN MEB 8301 being generated March 23,
- 1983, to identify this problem and determine the required corrective action.
As a result of this NCR, it was determined that this material installed in a high pressure system (design pressure greater than 150 lb/in2) which was safety-related and could not be isolated from other portions of the system was to be replaced.
Tests were performed for both physical and chemical properties.
The results of these tests (Appendix A of NCR GEN MEB 8301) showed that
- most of the fittings were acceptable and did comply at least with ASTM specifications in a
manner which would allow them to be certified to ASTM criteria.

- d. It was learned by the interviews conducted that this problem received high visibility, was controlled and documented.
==
Conclusion:==
This was found to be a Class B issue.
4.6 Cable 4,6.1 This concern was factual but not a problem.
This problem had been identified and corrected prior to the concorn being issued.
The material installed in the Steam Generator Blowdown System is acceptable either by initial purchase or by the disposition of NCR GEN MEB 8301.
It should be noted the Material Control Subcategory 40200 addresses the aspects of this concern related to purchasing.

- d. It was found by the interviews conducted that, in the subject timeframe (1979),
cable was received onsite based on receiving a TVA I&T QC checklist and shipping release.
The cable was placed in segregated storage and was not to be issued for use until notification that the "documentation is complete" was received onsite.
In addition, this notification was also sent to the Electrical Engineering Branch (EEB) for review and approval.
- e. It was found by reviewing the NCR log and the NCR's written for cable in the subject timeframe (1979), that one NCR had been written for cable being received without the l&T QC checklist and shipping release (NCR 1423).
This NCR, however, did not indicate that the cable had boen released for installation.
It was found, by reviewing five contracts for cable in the subject timeframe, that the I&T QC checklist and shipping release and the l&T notification that the "documentation is complete" had been received.
In addition lo this, an approval memo from EEB had been received.
go A review of the applicable site procedures revealed that the Z&T QC checklist and shipping release was required to have been received prior to the cable arriving on site or was to accompany the cable shippment.
Cable was not to be released for installation prior to a

- e. It was found that NSRS Report I-85-713-WBN and the DNC response did not address snubbers being scrapped.
- f. It was found, by observation, that although the scrap yard.is a fenced area, there is not a gate or any other means of controlling access to the scrap yard.
Portions of the material in the scrap yard were in usable condition, and it was questionable if some of this material should have been scrapped.
==
Conclusions:==
This was found to be a Class D issue.
There is a lack of control of material sent to the scrap yard and no mechanism in place to prevent this material from being used in the plant.
This could result in material being installed in the plant that had not been stored in accordance with the requirements of the ANSI N45.2.2-1972.

- 2. It was determined by roviowing NSRS report number T-86-164-SQN that the report adequately addressed the specific concern and there were no findings or recommendations,
- However, the overall program for the control of scrap material is not addressed.
c.
A review of site procedures and upper-tier roquiroments revealed that:
1.
During the construction phase of SQN there were no procedures that directly addressed scrap material.
- However, SQN Construction Procedure P-ll addressed stock piling material and this would require excess or leftover material to be properly handled at the completion of a work process.
2.
There are currently procedures in place addressing scrap material.
SQA-45 R/21 "Quality Control of Material and Parts and Services,"
Section 13.1 requires QA Level I, II, or III materials leftover or recovered in connection with maintenance, operation, or retirement of property shall be returned for credit or scrapped.
- However, SQA-148 R/0 "Saleable Scrap," Section 2.0, states "It is common place practice to retrieve from scrap metal piles materials which may be needed for use in plant maintenance work."
This could result in material that was scrapped being used in plant installations based on t.he fact that traceability of material was maintained after it had been scrapped.
3.
10 CFR 50, Appendix B, Criterion XII'I, requires measur'es to be established to control tho storage of material and equipment to prevent damage or deterioration.

From the interviews it was found that:
1.
During the construction phase of SQN, material was on occasion
- scrapped, its traceability maintained, and therefore retrieved for installation at a later time.
- However, no specific items could be identified.
2.
Currently, material leftover or retired from repair or maintenance operations is on occasion kept for possible future use on non-Quality Assurance (QA), non-Critical Structure System or Component (CSSC) work.
This practice occurs because it is difficult to return these items to Power Stores.
- e. It was determined by personal observation that material placed in the Power Stores scrap yard could not be retrieved for future use without making Engineering aware of the need for the material.
This is based on the fact it is placed in a Eonced and locked area, and access is controlled by the Power Stores Supervisor.
However, material leftover or retired from maintenance and modification operations in some cases is not returned to Power Stores for credit nor put in the Power Stores scrap yard.
Some of this material is placed in in-house storage areas for possible future use.
These storage areas are not controlled, the material is not identified as being acceptable for non-QA use
- only, and the storage conditions for some of this QA material is questionable.
==
Conclusions:==
This was found to be a Class E issue.
Specific items were not identified as having been scrapped and retrieved from the scrap yard for installation at SQN.
The program controlling material however, needs to be strengthened.

No additional information was obtained from QTC.
b.
No pertinent information was obtained by reviewing the expurgated file.
- c. It was concluded from the interviews conducted that Westinghouse material was delivered to WBN without the required documents in the timeframe (prior to June 1982) involved; however, the construction engineers responsible for the delivered material identified these problems
<<nd generated Nonconforming Conditions Reports (NCRs) to identify and correct these problems.
d.
It'was determined by reviewing WBN-QCP-1.06 R/0 effective June 17, L975 through R/9 effective April 19, 1982, that QA Westinghouse material received without the required documentation was to be nonconformed.
e.
IL was determined from the review of the NCR log that Westinghouse material received without the required documents in the subjecl.
timeframe was properly nonconformed (78 NCRs before 1982) and the closure of these NCRs requires these documents.
==
Conclusions:==
This was found to be a Class A issue.
Based on the above, Westinghouse material was delivered to WBN without the required documents; however, this material was identified, NCRs written
. and the condition was corrected.
Therefore, this concern is not factual.
No specific case was identified where documentation was not verified to have been eventually received.

4.9.1 Generic Applicability The concern addressed in this issue was site specific to WBN and the results of the evaluation showed that this concern is
- factual, but not a problem, and is not generic to other TVA nuclear pl'ants.
4.9.2 Plant-Specific Applicability 4.9.2.1 WBN a.
No additional information was obtained from QTC.
b.
The information obtained by reviewing the expurgated file was that the subject heat code was not in the printout for 3/4-inch pipe
~
- c. It was determined from the interviews conducted that 3/4-inch and 1/2-inch pipe having the same heat number did not constitute a problem.
Piping installed on a safety.related system would have the heat number verified when weld fitup inspection was performed and this was reviewed prior to preparation of the code data report by the NS group, Based on the location of the storage cack, this.is related to the construction department.
No specific location,
- system, timeframe or event was identified.
d.
Based on a review of site procedures, there is a
program in place to assure that safety-related pipe is installed with heat numbers that meet code requirements.
The adequacy of this program is addressed in Material Control Subcategory Procedural Control (MC-40700).
e.
No requirements were found in the ASME code that would prevent 3/4-inch pipe and 1/2;inch pipe from having the same heat number.
f.
A review of the WBN Heat Code Program identified 45 heat codes that were the same for 1/2-inch and 3/4-inch pipe.

Conclusions:==
This was found to be a Class B issue.
Based on the above, the fact that 3/4-inch pipe and 1/2-inch pipo have the same heat number is not a
problem.
Therefore, this concern is factual but not a problem.
This occurs bocause both sizes of pipe were manufactured from the same bulk material with a singular heat number.
This does not violate any site procedures or upper tier requirements.
The statement in the concern that a 12 foot length was partially installed before the problem was discovered indicates that the program being used was working.
4.10 Beam 4.10.1 Generic Applicability The concern addressed in this element was site-specific to WBN and was found to be factual, but not a problem; therefore, it is not generic to other TVA nuclear plants.

NCR 5942 was written (February 2,
1985) in the timeframe involved and addresses laminated W6 x 20 wide flange.
The disposition of this NCR allowed all of this material (same heat number) other than the 40-foot section identified during fabrication to be used.

QTC had provided additional information to the DNC person investigating this problem.
According to this individual, the CI was providing second hand information and the date of occurrence was approximately April 1985.
2.
A problem was encountered with some 6-inch wide flange beam in the hanger shop in the timeframe of this problem.
Project Engineering was notified and the section found to have laminations during fabrication was destroyed.
3.
The only laminated beam that could be identified in the limoframe involved was the W6 x 20 found in the hanger shop in February
- 1985, and addressed on NCR 5942 dated February 2,
1985.
The disposition of this NCR required that only the piece the lamination was discovered in, be destroyed.
- e. It was found by a review of the NCR logs (for the entire construction phase) that other material had boen identified with similar problems during construction of WBN and NCRs were written for these.
==
Conclusion:==
This was found to be a Class B issue.
This concern was found to be factual but not a
problom.
The problem with the laminated beam concern has been 'adequately addressed and the required corrective action taken.
Past practice at WBN has been to address problems similar to this in the same manner.
Based on the information available at the time of this report, this is not a problem.
NCRs have been initiated for this condition and the disposition has been "use-as-is" except for the specific laminated piece.
It should be noted that control of laminations is addressed in Material Control Subcategory MC-40600 "Quality of Material."

The problem at WBN unit 2 has been addressed by NCR 6773.
Since the same procedure was used for WBN unit 1, the accuracy of documentation, as well as suitability for service for the safety-related valves is questionable.
5.1,2 Valve Cracked Based on the fact that this issue was found noL to be factual, and that several Level III NDE specialists from separate organizations and independent of ono another concurred on this finding, this is not a problem.
It appears this concern was generated because someone involved in the installation, repair or maintenance of these valves observed one of the indications that is present in these valves and was unable,to determine the significance of the indications.

Although this is a factual issue, it was revealed that the root cause was isolated human error.
Therefore, this is not a significant issue.
5.1.4 Fittings (Without NDE Reports)
This issue was found to be factual, but not a problem, by the evaluation conducted.
Therefore, this issue has no significance.
Tt appears that the. concern this issue addresses was generated because the individuals involved in the work process are not aware of upper tier requirements and how they were implemented in the past.

3 PAGE 51 OF 62 5.1.5 Material From Uncertified Vendors Although the evaluation of this issue revealed that this did occur at WBN, the program implemented by TVA had previously identified this problem and adequate corrective action had been taken.
Therefore, there is no significance to this issue.
It appears that the concern this issue addresses was generated because the individuals involved in the work processes are not aware of upper-tier requirements and how they were implemented in the past.
5.1.6 Cable This issue was found to be factual but not a problem by the evaluation conducted; therefore, no significance can be assigned.
It appears that the concern this issue addressed was generated because individuals involved in the work process are not aware of uppor-tier requirements, and how they are implomented.
5.1.7 Scrapped Material This issue was addressed at all TVA nuclear plants.
At WBN, cases were identified were material was scrapped and retrieved for use in permanent plant features.
No instances of this occurring were identified at other.
TVA nuclear plants.
However, it was evident by the evaluations conducted that leftover, retired and excess material was not adequately controlled at all TVA nuclear plants.
Despite the fact that specific cases were not identified where scrapped material was used in QA applications, the program in place is inadequate.
TVA has no written or definitive program criteria in place to establish a method of determining how to address material that is leftover or retired at the end of the work process.
This has resulted in each plant developing their own method of addressing leftover and retired material.
The term scrap has rot been clearly defined and is used differently at some plants.
This lack of program criteria has resulted in inadequate control of leftover and retired material at the conclusion of the work process.
(When material is scrapped, it is not required to be unusable; and efforts to save this material for possible future use has resulted in many of the storage problems identified by the "Material Control" Subcategory

as well as the side issue identified at BLN by the construction subcategory "Hangers and Supports"
[11100].)
It should be noted that the problem identified at WBN was that usable material was being put in the scrap pile by mistake and then retrieved for use.
This happoned to a
limited number of items and procedures were in place to prevent unqualified material from being used.
S.le8 Westinghouse Material The concern addressed by this issue was found not to be factual.
Thorefore, this issue has no significance.
It appears that the concern this issue addresses was generated because the individuals involved in the work process are not aware of upper-tier requirements and how they were implemented in the past.

5.2 Collective S~inificence of the Snhcete ot 5.2 '
Management Effectiveness This subcategory 'addresses ten issues, of which throe were factual and represent a problem.
Two of the problems identified could be attributed to a lack of effective
TVA EMPLOYEE CONCERNS SPECIAL PROGRAM REPORT NUMBER:
40300 REVISION NUMBER:
3 PAGE 53 OF 62 management.
The findings for the scrap material issue indicate that management failed to implement programs to control leftover, excess and retired material at the conclusion of the work process as well as preventing the inadvertent scrapping of material during housecleanings.
The findings for the valve substitution issue indicate that DNE and DNC management failed to establish a good line of communication.
This resulted in a failure to establish a
valve program that would maintain the design baseline, meet commitments and requirements for WBN, and provide DNC with a workable program.
In addition to the above, management's failure to make employees aware of commitments and requirements caused several of the concerns addressed by this report to be generated.
If employees had been made aware of commitments and requirements, the valve substitution problem might not have occured.
It should be noted that management effectiveness was impacted by the fact that requirements and commitments changed at each TVA nuclear plant, and that decisions based on experiences at'ther plants were not always appropriate.
5.2.2 Employee Effectiveness The findings for this subcategory indicate that employees were effective in that procedures were adhered to and that an effort was made to prevent wastefulness.
It was apparent
- however, that while procedures were followed, there was a
lack of knowledge and understanding of programs, requirements, and commitments, This can be attributed to inadequate training caused by a lack of management awareness.
5.2.3 Technical Adequacy The subcategory findings in this report do point outareas in which technical effectiveness is suspect.
Unauthorized valve substitution at WBN has resulted in the design baseline for valves to be questionable, as well as the suitability for service to be indeterminate for these valves.
The practice of scrapping mat;erial and retrieving it from the scrap yard for use has resulted in the suitability for service for this material to be questionable at WBN.
- Overall, the technical adequacy for the issues addressed by this subcategory was found to be acceptable.

3 PAGE 54 OF 62 6,0 CAUSE 6.1 Valve Substitution (Issue 1,2.1)
The inspection procedure (WBN-QCP-4.10.9) used for verifying that the correct valve was installed did not require verification by QC to the design requirements.
This procedure required verification that the valve installed was the valve specified by the DNC engineer.
This indicates that the review of this procedure was inadequate.
In addition to the above, the procuroment practices used by DNE wore found to be very restrictive.
This resulted in valves that were physically identical to have unique identification and the Bill of Materials drawings specified the valve but contained a notation "or equal."
The "or equal" notation was required for procurement, but DNC interpreted this as allowing construction to substitute
- valves, which precipitated valve substitution.
All of the problems identified above can be attributed to a failure by DNE and DNC management to effectively communicate.
Effective communication would have resulted in procedures and a valve identification program that would meet the commitments and requirements but allow construction as much flexibility as possible with the correct interpretation of "or equal" on the Bill of Materials drawing.
6,2 Valve Cracked (Side Issue)
The problem identified as a side issue at SQN (see 4.2.2.2) was caused by a failure to implement criteria for determining, the acceptability of the subject valve.
It should be noted that these valves do not normally receive this type of examination.
6,3 Fittin s (Heat Code M-157) (Issue 1.2.3)
The evaluation determined that there was and is a program in place for verification of CMTRs.
A review of the other heat numbers on the involved CMTRs found no additional errors.
A review of NCRs found 5 in 500.to be for similar problems.
The result of these findings indicate that problems similar to this are being identified and corrected, and this specific problem was caused by isolated human error, 6.4 Sera ed Material (Issue 1.2')
Failure by TVA to implement a program that would control leftover, excess or retired material so as to prevent material from being retrieved from scrap for-use in the plant and a failure at WBN to have a material control program in place,to prevent usable material from being scrapped and material in the scrap pile from being removed for use.
