2.0 Licensee Action on Previous Ins ection Findin s
2. 1 Closed Ins ector Follow-u Items 83-18-07 Electrical Conduit Im ro erl Identified 83-18-18 Electrical Cable Tra s
Im ro erl Identified.
The NRC Construction Appraisal Team (CAT) identified seven (7) con-duits and a number of cable trays with temporary identification (ID)
markers attached.
The licensee had no reinspection plan to assure that the temporary ID markers would be replaced with permanent ID markers.
Also, they had no plans to replace the temporary ID markers on the cable ends with permanent ID markers when the cables were terminated.
The following documents were reviewed to determine the corrective action taken by the licensee:
Electrical Specification NMP2-E061A, revision 9, dated October 5,
1984 Electrical Raceway Installation QA-Inspection Plan N20E061AFA002, revi sion OD
Electrical.Cable Pulling Instal 1'ation QA-Inspection Plan N20E061AF025, revision OF Electrical Cable Termination QA-Inspection Plan N2061A026, revision OC NM QA Checklist No. E-025-S-CO, revision 1,,NRC Identified Item
¹CAT 6-83, revision
NM Surveillance Report No. E-84-631, dated 6/19/84, Unscheduled Surveillance NRC Item ¹CAT 6-83, revision
In addition to the above documents, the inspector reviewed nineteen (19)
QC inspection reports, which verified that one thousand five hundred seventy one (1571) conduits and eight hundred twenty five (825) cable trays were reinspected to assure that permanent ID mark-ings were attached to the raceway.
The QC inspectors identified thirteen (13) conduits and thirty four (34) cable trays that had temporary ID markings which were changed to permanent ID markings.
The electrical specification no longer permits temporary ID markers to be placed on either conduit or cable trays.
The specification requires the temporary cable end ID markers be removed and replaced with permanent ID Markers when the cables are terminated.
The QA-Inspection Plan (Raceway Installation) requires the Field Quality Control ( FQC) inspector to perform a visual inspection for permanent ID markers on each raceway before the raceway can be
'accepted.
The QA-Inspection Plan (Cable Installation)
has a hold point that requires the cable raceway be accepted by FQC before any cable is installed.
The QA-Inspection Plan (Cable Termination)
requires that the FQC inspector verify that the temporary ID markers are removed from the cable ends and replaced with permanent ID markers when the cables are terminated.
The revised Electrical Specification and the revised QA-Inspection Plans assure that raceways and cables will be properly identified.
During this inspection no improper identification of either raceways or cables were observed.
Both items 83-18-07 and 83-18-18 are closed.
2.2 Closed Construction Deficienc 84-00-30 Non uglified Circuit Breakers in Division III Batter Char ers.
The licensee identified that four (4) nonqualified Square D circuit breakers were installed in battery chargers 2BYS*CHGR2C1 and 2BYS'CHGR2C2.
These should have been qualified circuit breakers, manufactured by Westinghouse, as specified on the bill of materia ~
~
The nonqualified Square D circuit breakers were replaced by qualified Westinghouse circuit breakers in accordance with Nonconformance and Disposition No. 8444.
The Site QA NRC Item 84-00-30 Evaluation and Verification Report, dated May 16, 1985, verified the corrective action above.
The inspector further verified by visual inspection that Westinghouse breakers were installed in the battery chargers.
This item is closed.
2.3 Closed Ins ector Follow-u Item 83-18-05 Mechanical and HVAC su orts rotruded into cable tra 83-18-06 Mechanical S ecifications and Ins ection Plan re uire revision for cable tra rotrusion.
The NRC CAT team identified two cable tray installations in which mechanical and HVAC support members had protruded into the cross sec-tional area of the cable tray.
The concern of the CAT team was the licensee had no method to prevent this from occurring again.
The following documents were reviewed to determine the corrective action taken by the licensee to correct the identified problem and prevent similar reoccurrence:

NRC Identified Item
¹CAT 6-83, revision
NM Surveillance Report No. E-84-631, dated 6/19/84, Unscheduled Surveillance NRC Item ¹CAT 6-83, revision
The electrical specification and raceway gA-inspection plan has been revised to include the following statement:
Protrusion of pipe, HVAC, etc., or associated supports into the area designated by the upper and lower plane of the tray and the side rails of the tray are not acceptable.
The S&M field fabrication and erection specification and the structu-ral, mechanical and fire protection gA-inspection plans have also been revised to include the following or similar statement:
Pipe support member shall not protrude in the cable tray clear-ance envelope as shown on sketch SK-4710-MS-84.
Interferences of this nature shall be addressed to the Engineers.
All devia-tions shall require approval by the lead electrical engineer.
Other specifications listed above, excepted those discussed, have not been revised but are controlled by E&DCRS F01238 and F01164.
The protrusion into the cable trays identified by the CAT team has been corrected by the licensee.
The revised specifications, gA-Inspection Plans, and the E&DCRS provide assurance that this problem will not reoccur.
Items 83-18-05 and 83-18-06 are both closed.
2.4 Closed Ins ector Follow-u Item 83-18-03 Electrical Racewa Ins ection Documents Deficient.
Inspection documents, such as raceway tickets, used for electrical raceway installation did not reflect the following:
Drawing revisions Engineering change documents The final F(C document is the completed raceway ticket which did not have the above information.
As such, there was no documented record of the design requirements in effect at the time the raceway was installed, inspected and accepted.
The inspector reviewed the revised Electrical Raceway Installation gA-Inspection Plan N20E0601AFA002, revision OD, and noted that the plan requires that the following information is recorded:
Engineer
& Design Change Request (E&DCR)
Advance Change Notice (ACN)
Drawing revision number Specification revi sion number The revised QA-Inspection plan provides the FQC inspectors with guidance to assure that there is a documentation record for the systems or components inspected.

2.5 0 en Construction Deficienc 84-00-18 Hi h Pressure Core S ra HPCS Diesel Generator Panel Wirin Deficiencies.
The issue concerns the HPCS diesel generator control. panel (2CES*IPNL413) furnished by General Electric Company (GE).
GE's supplier for this panel was Stewart
& Stevenson.
Approximately thirty percent of the wiring in this panel has been found to be improperly crimped to its termination lug connector or damaged.
The corrective action was to repair the termination, as described in the Nonconformance and Disposition Report (N&DR) No. 6367, in accordance with GE Field Deviation Disposition Request (FDDR) Report No.
KG1-1015.
Two hundred forty eight (248) terminals were relugged and crimped.
The panel was reinspected as part of a 100% re-inspection program with fifteen criteria identified in E&DCR No.
C02, 589 ( see open item 85-04-03 paragraph 2.6).
Additional terminals were identified which require relugging and crimping.
These are documented in N&DR No. 11,637.
The licensee has amended the
CFR 50.55 (e) report to include panel 2CES"IPNL414.
The work is not complete on either panel.
Pending work completion, this item remains open.
2.6 0 en Unresolved Item 85-04-03 Electrical E ui ment Vendor A
Pro ram Inade uate.
In response to deficiencies identified by the Construction Appraisal Team (CAT) inspection relative to the conduct of the SWEC Procurement Quality Assurance (PQA) program, the licensee committed to perform a
sampling reinspection of electrical components to ensure compliance with the design requirements.
The sampling inspections performed have served to further confirm the presence of inadequate equipment supplied by the associated vendors.
Internal wiring deficiencies have been identified within the following electrical equipment:
HPCS Diesel General Control Panels (see 84-00-18) above).
Motor Control Centers supplied by Gould.
Switchgear supplied by Brown-Boveri.
Diesel Generator control panels supplied by Cooper Energy Service ~
~
~
~
The above problems have been reported to the NRC under the
CFR 50.55 (e)
as potential construction deficiencies.
As a result of the above, the licensee plans to expand their reinspection program in the area of internal wiring.
At the time of this inspection, the licensee was unable to provide the following information to the inspector regarding the reinspection program.
A list of equipment to be reinspected The criteria to be applied to this reinspection The Nonconformance and Disposition Report Discussion with the FgC personnel indicates that wiring termination inspection and'ework is presently being done.
This was further confirmed by observation and discussion with craft and startup personnel working on all three diesel generator panels.
Pending licensee's completion of the reinspection program and NRC review of the above information, this item remains open.
2.7 0 en Deviation 83-12-06 F
C Ins ectors not ivin written consent at hold pints before allowin work to continue.
Contrary to ANSI N45.2, gC inspectors were witnessing and/or inspect-ing cable installation without the required written consent being documented prior to continuation of work beyond the designated inspection plan hold points.
The licensee has revised both electrical specification E601 and associated FgC inspection plans to prevent the above identified problem from reoccurring.
However, the licensee has also identified thirty eight (38) additional inspection plans that require a change to reflect the mandatory hold points.
The licensee was unable to provide evidence that the additional inspection plans have been revised.
This item remains open.
2.8 0 en Violation 85-04-03 Failure to Follow Stora e Procedure.
On February 11, 1985, the NRC inspector noted that electric heaters on emergency diesel generator (EDG) and components were not energized as required and verified by quality control inspector as required by storage procedure LSpecification SM01].
The licensee's response to this violation, concerning the deener-gization of the EDG heaters, was the equipment will not experience any detrimental effects from the heater being deenergized for brief periods of time.
However, to assure that proper notification of
~
v
"ly
interruption of storage and maintenance requirements is provided to the PM manager/designee, a directive has been issued by the licensee to contractors and department heads to comply with the site procedure.
During this inspection, it was again observed by the inspector that the space heaters were not energized for the three EOG's.
The power was removed for five (5) days and would remain off for an additional three (3) days to complete the reinspection of wiring within the EOG's panels.
The licensee has not quantified what constitutes an acceptable brief time for deenergization of equipment space heaters.
Nor have they specified required activities should this period be exceeded.
Pending NRC receipt and review of the above information, this issue remains open.
