The inspector examined Shutdown Panel-Train A to verify the damaged indicators were replaced. Discussions were held with the licensee l to determine .when the damage occurred .and if is was overlooked by inspection personne These items were found to be indeterminat However, additional component inspections will be performed during the area turnover walkdowns which should identify physical damage as found on the indicators. The shutdown room has not been turned over. Procedure GD-A-50, Nuclear Construction Area Turnover, Revision 4 dated February 25, 1988, requires all components be inspected for physical damage during the area turnover walkdown . Unresolved Items Unresolved items were not identified during this inspectio . Electrical Components and System, Work Observations (51053); Electrical Components and Systems, Record Review (51053); Electrical Cable, Record Review (51065)

The inspector examined three electrical penetration assemblies (EPA) in which cables were being terminated at the inside containment connections ,

using or having used heat shrinkable tubing material These EPAs have l had a gridwork of steel added to each termination box to support the i weight of the incoming cables. This steel along with the added weight of the cables will be evaluated by the licensee to insure that the resultant moment is within the manufacturer's tolerances. All the EPAs had the covers installed to provide protection from the surrounding construction activitie ,

The EPAs reviewed to the detail described above were: l I

2APS22 Control Voltage Penetration i 2APS21 Medium Voltage (Power) Penetration l 22PY46 strumentation Penetration The inspector reviewed the following ten Field Change Requests (FCR) for adequate engineering evaluation, review and control:

3-These FCRs were onetime deviations 'from the electrical construction and design Specification No. X3AR01, Section 16 to permit a special case field installation and are designated as "NA/NA" FCRs in that no drawin notice (DCN) or construction specification change notice (CSCN)g were change ,

required / issued. The FCRr, were evaluated by the appropriate engineering unit, reviewed by-.QA when required and reinspected by QC as require A review was made of the installation documentation which verified the torquing of the EPA mounting rings and the attachment of the EPA-internals. The installation. inspection was conducted and documented in accordance with Construction Procedure ED-T-04 Installation of Major Electrical Equipment. The receipt inspection records were also reviewed and found in ceder. The storage inspection records which document the maintenance of the internal gas blanket pressure had been tranrferred to the operations section along with the surveillance responsibilitics. and were not reviewed during this inspectio :

i The following QA audits were reviewed by the_ inspector:

CP0-87/62 Audit of the Electrical Contractor and Electrical Field Operation Audit of planned and systematic controls applied to the construction, fabrication and installation of electrical system CP09-86/60 Audit of Electrical Contractor and Electrical Field Office Activi ties . Review of drawing control activities, equip-ment installation and documentatio CP09 87/12 Audit of Electrical Contractor and Electrical Field Offic Review of Main Control Board Installation Activitie CP17-87/57 Audit of Electrical Contractor and Electrical Field Officer

- Review of Cable tray support installation activitie CP18-87/47 Audit of Electrical Contractor and Electrical Field Office Review of Cable pulling and routing activitie The above QA audits were performed in accordance with the planned audit schedule which was aligned to the construction activities in progres The findings were sufficient in detail to provide meaningful direction to the personnel responsible for detailing the corrective action .

The corrective actions taken were verified by the auditor before each finding was close It should be noted that a finding in Audit No. CP01-87-62 listed above identified a problem with separation between Non-IE and IE service level cable trays not meeting the specified criteria in one area of the plan l The licensee has submitted a potentially reportable concern M142 to the 1 NR Further evaluation is in progress, i

The inspector selected a random sample of closed Deficiency Reports (DR)

for evaluation of the item to meet the reporting requirements of 10 CFR 50.55(e) and Part 21. The DRs were maintained.in well coordinated files with an index available which provided a brief description of the item

.and the current status of the evaluation process for each item. All DRs reviewed appeared to have had adequate engineering review and often contained copies of the evaluation for the corrective action recommende These DRs addressed deficiencies in conduit supports EPAs, cable installa-tion problems, circuit breaker wiring, electrical junction boxes and panel-internal wiring. Listed below are the identification numbers of the DRs reviewed:

ED16001 ED16004 ED16005 ED16008 ED16014 E016015 ED16022 ED16036 ED16060 ED16100 E016149 ED16234 ED16277 ED16347 ED16510 ED16529 ED16516 E016635 ED16664 E016677 The inspector examined the certification and training records for five QC inspectors. All certifications were curren The educational records were adequate to support the levels at which_ the inspectors were certified and were supported by training records and test score Within the area examined, no violations or deviations were identifie . Instrument Components and Systems - Work Observation (52053)

The inspector performed walkdowns in the auxiliary building, the control building, and the containment building to observe completed work for damage and whether temporary protection is provided. where needed to 4 prevent damag The completed work examined was various instrument ;

installations, tubing runs, racks and panel During construction, temporary protection is generally required to prevent inadvertent damage i from other adjacent construction activities, especially welding and being stepped on. Instrument tubing is an item that is susceptible to damage j and was given special attention, j i

In the containment building, instrument tubing for the four steam !

generators and the pressurizer was examine This tubing was inspected since insulation lagging was in the beginning stage of being installe The flexible hoses (required for thermal growth) from the condensing pots on the vessels to the tubing were given special attention to assure the protective wire braiding was not damaged. In the auxiliary building, ;

instrumentation and tubing were inspected in the following area: 1 Room 119 Safety Injection Pump A Room 118 Safety Injection Pump B Roon 4 RHR Pump A

In the control building, Shutdown Panel - Train A and Shutdown Panel -

Train B were inspecte Both panels were adequately protected. Shutdown Panel - Train A was examined to determine if the previously- found damaged indicators had been replace The indicators were replaced (See Unresolved Item 88-16-01-closed).

The inspector did not identify any ' damaged instruments,- tubing, racks or panels or any items which were not adequately protecte Within tae areas examined, no violations or deviations were identifie . Instrunent Components and Systems - Record Review (52055)

The inspector examined personnel qualification records, nonconformance and deviation reports, and change control records for instrumentation. These records were reviewed to determine whether adequate preparation, evalua-tion, review, and control had been made and the records reflect the requirements of Georgia Power Company (GPC) and the mechanical instru-mentatic, contractor, Pullman Power Products (PPP).

The persont.el qualification records for eight technicians and three foremen in the Instrumentation Section of the Startup Group (Test) were reviewe The records for both contract and GPC personnel met the requirement in Procedure SUM-24, Initial Test Program Personnel Certifica-tion. The records are sufficient to support qualifications in terms of certification, experience, proficiency, and training in the areas of instrumentation calibration and testin Deviation Reports (DR) written by PPP during the construction phase and -

Operation Deficiency Reports (0DR) written by GPC during the test phase were reviewed for the following attributes:

Records are legible, complete and promptly reviewed by qualified personne Records are properly identified and stored, indicate current status and are readily availabl Records include the status of corrective action or resolution, and adequate justification is provided for the "USE As-Is" dispositio The DRs and 00Rs reviewed are listed as follows:

required for splice kit The materials are closely controlled and maintained (stored) in a temperature controlled building. Each splice kit l 1s assembled and sealed in plastic containers which when opened can not be resealed. All kits are issued for specific connections and are closely controlled to insure that they are properly installe The inspection guidance and acceptance criteria are contained in Procedure l ED-T-08 Cable Termination. A check list signoff is contained in this procedure for QC documentation of the . in-process inspection as . it is performed and when required. The inspector observed the termination of power cables 2AHJB0780 and 2AH2628WB, which incorporated HST kits, in EPA 2APS 2 The termination of cables using HST kits located in 480 Control EPA 2APS 22 were examined es were several instrumentation cable i terminations located in instrumentation EPA 22PY4 l I

It was noted that during installation of the heat shrink materials care

'

was taken to insure that the materials were cool before proceeding to the l
