PAGE 4 0F.11 Inspection' Performance The NSRS investigated these issues and issued report No.. I 101-SQN dated February-1986 ( Attachment. B).
A Corrective Action Report dated February 1986 was also issued.
Two valves were found to have connectors'where wire bend radii were below minimum requirements - and workplans.were found to have - been written where work was performed and.' inspected;. however, the plans did not refer to the vendor manual for installation of the connectors.
Lack. 'of QC management 1 action. could not be verified since the QACEG could. find no evidence to. determine if the concerned-individual brought this issue to QC Management prior to the NSRS investigation.
The issue of the connectors not meeting the wire bend radius instructions and connectors being installed and accepted with deficiencies is valid.
A reinspection was initiated by TVA Management.
Specific corrective actions and the results achieved to date are discussed below.
2.3.4 Issue -- A item of equipment may not have been adequately inspected.

This issue could not be evaluated since there was-insufficient.
information available to perform an investigation.
l I
2.4 Corrective Actions Taken and the Results Achieved to Date It could. not be determined if-cable insulation was improperly repaired.
However, - QACEG investigation has determined, through the issuance of Corrective Action Tracking Documents and Responses from the SQN Site Director, that the subject cables have been tested, 3,.
experienced worst case conditions, and been 'in service since 1977.
Engineering concluded 'if there was. insulation damage, it was not sufficient to impair the fuention of the cable and no further action f(
is needed.
j Conax connectors were installed outside the allowable limits.
A Corrective Action Report was issued causing for a QA Program revision, reinspections and rework.
This ' was completed in August 1986' and no further actions are required.

4.2.1 Issue -- Inspection personnel were distracted by craft personnel and did not observe damaged cable instruction.
a fj In researching the files for additional information regarding craft distracting inspection persdhnel and cable insulation 3
damage, QACEG personnel reviewed a related concern (00-85-005-4 014) which identified the specific cable / conduit runs involved.
Four cables were identified.
That concern also identified the period of time as mid-1977.
f.
Microfilm records relating to-the above identified h
cable / conduit runs were reviewed (cable pulling
- cards, q
cable / conduit inspection
- cards, and Hi pot records) to 4
determine if inspectio'ns were performed and ' tests completed.
O An interview was held with an individual involved in the inspection of three (3) of the above noted cable pulls.
The q
interview centered around how an inspector may become 5
distracted and how an inspector can cover the inspections I
given the various areas cable is pulled through.
General Construction Specification G-38, Revision 1,. dated October 22, 1975 " Installing Insulated Cable Up to 15,000 Volt Inclusive", was reviewed to determine if instructions were provided for repairing damaged cable and/or insulation.

tests.and related documentation.
An Employee Response Team (ERT) Report (XX-85-023-X02, dated
-March, 1986)- (Attachment, C) was found to address the same issue.
The QACEG investigation attempted to secure a listing or the hangers in the Unit 2 Annulus area since the employee concern identified this area specifically.
A list of hangers by location does not exist, according to Engineering, and it was concluded that if records. were located it would be extremely difficult to establish if the test results-were falsified.
Therefore, emphasis was placed on locating and discussing the issue with personnel who were involved in anchor bolt installations / inspections in that period.
A review was performed of General Construction Specification G-32,
" Bolt Anchors. Set In Hardened Concrete" Revision 4 (dated April 21, 1976).and Revisio'n 5 (dated July 21, 1977) to determine the installation and test requirements. ' Inspection Instruction SNP 11-93, " Testing of. Expansion Anchors Set in Hardened Concrete", Revision 0 (dated February 14, 1977),

In ~ researching the
' issues concerning Conax connector deficiencies, the QACEG Evaluation Group interviewed the QC
' Electrical Supervisor.
A copy of Corrective Action Report SQ CAR-86-02-005 dated February 10, 1986 was furnished by this individual.

5.0 FINDINGS 5.1 Findings on Issue - Inspection personnel were distracted by craft

personnel.
5.1.1 Discussion Concern No. 00-85-005-003 dealing with the inspector being
-a distracted and preventing him from noticing damage to cable insulation referenced Concern No.
00-85-005-014 which identified four specific cable / conduit runs.
That concern stated in part, " Insulation was mistakenly cut off of a 440 volt cable and the insulation was reattached with electrical i
tape."
The concern went on to identify the cables as the power feed to the Back Plow Gate Hoist Motors.
There are four such motors and*are.part of the Essential Raw Cooling Water-(ERCW) System. That same concern identified four cable / conduit runs as 1-PL-6370-B, 1-PL-6360-A, 2-PL-6370-B and 2-PL-6360-A and also identified the period of time as mid-1977.
Concern No. 00-85-005-014 is a reissue of Concern No. 00 005-001.
The reason for ' reissue was a correction of one of the cable numbers referenced in the concern.
This concern was part of the Construction Element Report No. C010900-SQN and-the particular issue is addressed under the heading
" Insulation Damage".
Inspection records show that two (2) inspectors were involved with the cable visual examinations of the identified cable / conduit runs in the period from June-September 1977.
An interview was held with an individual involved in the inspection of three (3) cable pulls (1-PL-6370-B, 1-PL-6360-A, and 2-PL-6360-A).
The interview centered around how an inspector may become distracted and how an inspector can cover 1

The. individual involved with cable puli 2-PL-6370-B inspection could not-be interviewed as he is no longer-employed by TVA.
The individual interviewed, who inspected-three of the four cables in question, stated that because of the various areas a cable may be ' pulled through the inspector could not always witness the - entire operation.
In his opinion, the point at issue could have happened.
In reviewing the records it was noted that the four (4) cable / conduit runs referenced are'non-CSSC and received acceptable installation inspection and 4
testing through the period June-September 1977.
These cables received and passed a.Hi-Pot Test.
It was also-found that-the cables have - been de-energized and per -ECN L5720, the electrical circuit for the Back Flow Gates have been converted from automatic control to manual control.
In discussions with the Design Engineering personnel and a E
review of the drawings associated with the motors and cables, it was found that the design drawinds 45N-751-1,
-2,
-5, and -
6 do not reflect that the cables have been de-energized and f
motors taken out of service.
h 5.1.2 Conclusion The issue of an inspector being deliberately distracted from noticing a cable insulation nonconformance and the same inspector being distracted while the cable was improperly I'
repaired and pulled into the conduit cannot be substantiated.
However, since the referenced cables have been de-energized the issue raise'd by.the concerned employee is invalid at this time.

They too denied knowlege of falsification of test records.
j The Office of General Counsel (OGC), in their memorandum to l
the Manager of Nuclear Power dated April 30, 1986, concluded l
that in its review of the QTC investigation into the issue of craft and inspection personnel falsifying anchor pull tests i
and documentation there was
"...no collaborating / objective l
evidence
...found to allow substantiation."
The Office of General Counsel will take no further action on this issue.
In a phone conversation with the Office of the Manager of Nuclear l
Power, ONP advised that it has accepted the decision of the t
Of tice of General Counsel regarding this issue.
"The Construction CEG has performed an extensive investigation 4
and evaluation of the anchorage issues and has reported on their findings in Subcategory Report 11300 Revision O.
5.2.2 Conclusion r
Based on interviews, lack of data 'to support the issue, the ERT Report and the OGC memorandum, it is concluded that the issue of craft and inspection personnel falsifying anchor pull tests and applicable documents is not substantiated.
5.3 Finding on Issues - Conax connectors in the containment did not always meet vendor wire bend radius instructions, connector installations with deficiencies were inspected and accepted by Sequoyah Quality Control (SQN QC); no action was taken by SQN QC management to investigate or document the deficiencies.
5.3.1 Discussion The issue dealing with Conax connectors and deficiencies noted was the subject of a NSRS Report of " Installation of Conax Connectors", I-86-101-SQN dated February 1986 and a Corrective Action Report (CAR)
SQ CAR 86-02-005 dated February 10, 1986.
Two valves were verified to have wire bend radii below minimum allowed.
A sample was than taken from Units 1 and 2 and an additional 14 valves were found to have deficient wire bend radii.
Workplans were written to install the connectors, field installation was completed and inspections were performed.
Work plans did not contain steps e
to verify wire bend radius nor did they reference the vendor manual for installation.
(Reference Attachment G for general 4
arrangements details for Conax Connector.)
A review was made of the CAR and a subsequent revision to 4

A 100% reinspection for the minimum bend radius and rework as necessary to all Conax connectors, and the~ EQ 4
Project Manager's concurrence with the vendor manual revision have been performed.
TVA QA ~ verified corrective action was taken and CAR 86-02-005 was closed in August 1986.
5.3.2 Conclusion The issue of Conax connectors installed in containment that do
?~
not meet the vendor wire bend radius instructions was substantiated.
However, this condition was documented in SQ CAR-86-02-005, reinspections have been performed, and corrective actions have been completed.
p The issue of connectors < being inspected and accepted by QC 4
with deficiencies is factual since there were. cases found l
where wire bend radii was inadequate.
Work Plans for the installation of the connectors did not address bend radii when q
issued.
General Construction Specification G-38 did. not L
address wire bend radii'either.
Iniipections were conducted to the requirements of the approved workplans.
It was the d
omission of minimum wire bend radius inspection criteria in the workplans which allowed the connector installation to be f'
accepted by QC.
The inclusion now, of vendor. instructions for minimum bend radius in the M&AI-19 (RI) will preclude the omission of bend radii inspections in the future.
r The issue ot no action being taken by SQN QC Management to investigate and document. the deficiencies prior to the NSRS investigation cannot be sushtantiated.
No evidence exists to determine if anyone knew there were deficiencies prior to the investigation.

In researching this issue the QACEG could not find any specific information to aid in a meaningful investigation.
5.5 Corrective Action Corrective Action Report CAR-86-02-005 was issued in February 1986 to document that Conax connectors were installed outside the allowable limits.
Corrective actions included Environmental Qualification (EQ) review and concurrence with the Conax Vendor Manual and issuance of Rev. I to Maintensuce and Addition Instruction M&AI-19 to included wire bend radii criteria.
Reinspections and rework was performed on all Conax connectors and verification by Quality Assurance (QA) was j
completed in August 1986. No further actions were required.

The ECSP Corrective Action Tracking Document Nc..
80203-SQN-01 (Attachment E) which was issued on September 18, 1986 was issued for Engineering to evaluate the long term effect on the cables being repaired with electrical tape.
The SQN Site Director has since responded by saying that records indicate acceptable installation and testing (Hi-Pot and Megger).
The cables have been in service since 1977 and it is likely that they have experienced the worst conditions including submergence during that time without any problems.
Engineering concluded that if there was damage, it was not sufficient to impair the function of the cable and no further action is needed.
With the additional information made available to QACEG and further.
research where it was found that Engineering did not reflect the status of the cables as being de-energized on the design drawings, QACEG has prepared CATD 80203-SQN-02 (Attachment F) for SQN to evaluate the problem condition in light of their response to CATD 80203-SQN-01.
The SQN Site Director has responded by stating:
" Design Drawings 45N751-1,
-2,
-5 and -6 do reflect the system status, however, the electrical circuit for the back flow gates had been converted from automatic control to manual control by the unit operator (ECN L5720) which he has authority to do.
The breakers tor the back flow gate hoist motors are being tagged with ' caution order' of the administrative operation."
r QACEG concurs with this response and no further action is required.
Attachment A identified,these issues as potentially safety related and safety significant.
- However, corrective measurn-which include procedural revisions rework and reinspection have been completed.
No further action is required.

1980 (DES-80-12-17-021), and DCR-971 We recom:: tend disapproval of SQ-DCR-891. The subject pressure switches for units 1 and 2; PS-0131 A and B, -132 A and B, and -134 A and B; were L
safety-related switches to activate the closure of the CCW backflow gates.
This functional requirement was deleted when the new essential raw cooling
}
watei pumping station was activated.
As long as these suitches are installed, they can activate the closure of the backflow gates and possibly trip the unit. Since the safety-related 4
closure requirement of the backflow gates no longer exists, the closure of the backflow gates and the shutdown of any CCW pumps shogld be under ths J,
. control of the unit operator and not automatically actuated.
