Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve noncompliance or deviations.
New unresolved items identified during this inspection are discussed in paragraph 6.
5.
Independent Inspection Effort (Units 1 and 2)
The inspector toured the auxilliary building and the intake structure to observe the current status of construction and facility housekeeping.
Areas observed included the control room, 4160 volt switchboard and motor control center areas and 125 VDC distribution areas and battery rooms.
Housekeeping was considered adequate in all areas inspected. The internal compartments of terminal cabinets IIC15 and IEATC7 and panels 6 and 14 of 4160 volt switchboard IETA were observed to be clean and adequately preserved.
The in place storage of 4160 volt motors for Component Cooling Water Pumps 1A1 and 1A2, Safety Injection Pump 1A and Centrifugal Charging Pump IB were also inspected. All pumps were observed to be protected from construction activities and to have both a visible oil level and heat applied to windings.
Equipment Storage and Maintenance Inspection records, form P3A, were current for each of the selected pumps and indicated that periodic maintenance and inspections were being performed per the requirements of Duke Power Company (DPC) procedure P3, " Storage Inspections".

Electrical (Cables and Terminations I) - Observation of Work and Work Activities and Review of Quality Records (Unit 1)
The inspector selected eight safety-related power cables identified as 1*RN 501, 1*RN 668, 1*RN 669, 1*KC 501, 1*EPE 529, IEPE 530, 1*EPL 501, 1*EPL 504 and 1*EPL 520 for inspection.
Storage, handling and identifi-cation of cables 1*KC 501,1*EPL 504 and 1*EPL 520 were in accordance with DPC Quality Assurance Program (QAP) procedure P-1, " Receiving Inspection".
Safety-related cable reels observed in the site cable storage area were above grade with ends sealed and protected where required. Size, type location, routing and pulling of cables 1*KC 501,1*EPL 504 and 1*EPL 520 were verified using cable pull cards and were per the requirements of DPC QAP procedure d-40, " Electrical Cable Installation and Inspection". Although cable 1*KC 501 had been routed correctly, the conduit installation from cable tray node 5803 to CCW pump 1A1 was not in accordance with Installatin Specification number CNS-1390.01-00-0048, revision 3,
" Instructions for Mounting of Field Run Cable Support Systems", which provides the instructions for the installation of all safety-related field run conduit. The conduit run to CCW pump 1A1 had a ceiling mounted pull box installed which is not authorized by Installation Specification No. CNS-1390.01-00-0048. Although DPC drawing No. CN-1214-5, Rev. 2, " Auxiliary Building Electrical Equipment Seismic Mounting Plans, Sections and Details" does provide a detail for pull box installation the detail applies to wall or column mounted pull boxes of a t pe different from that installed in the CCW puep 1A1 conduit Additionally, drawing No. CN-1214-5 is not referenced by installation run.
specification No. CNS-1390.01-00-0048. The conduit run to CCW pump 1A2 was observed to have the same type of pull box installation. The licensee's QC inspection of the pull box installations had not yet been performed. The licensee documented this problem on Nonconforming Item Report (NIR) No.
6339. This item was identified to the licensee as Inspector Followup Item No. 413/79-16-01, " Pull Box Installati.o a Not Covered By Procedure."
The installation of the cable 1*KC 501 cable tray section between junction points 13775 and 13776 was verified to be in accordance with DPC drawings CN-1897-01R12, CN-1897-01.01R6, CN-1897-02R10 and CN-1891-06,R4.
The installation of cable 1*EPL 501,1*EPL 529 and 1*EPL 530 cable tray section between junction points 12512 and 12514 was inspected per the requirements of DPC drawings CN-1893-01R8, CN-1893-05R3, CN-1893-07R6, CN-1903-01R13, CNS-1903-04R7 and CN-1903-05R3, and the following discrepancies were identi-fied.
.
Hanger SC of drawing CN-1893-01 and as detailed on drawings CN-1893-05 a.
and CN-1903-04 had an incorrectly sized ceiling mounting plate installed on one of the legs. The seismic detail requires a 7" x 10" plate whereas a 6" x 10" plate was actually installed.
Two of the anchor bolts for the plate did not appear to have sufficient engagement in that approximately 5 washers had been installed as shims below the nut. Additionally, the plate did not appear to have adequate surface contact with the ceiling.

b.
Hanger 6C of DPC drawing CN-1893-01 which is detailed on DPC drawings CN-1893-05 and CN-1903-04 had one verticel member that had an actual installed length of 3'-8".
Drawing CN-1893-05 aquires a length (identified as L1 on drawing) of 3'-6".
The installed length appears correct for the in.:tallation. Additionally, one of the ceiling mounting plates did not appear to have adequate surface contact with the ceiling.
It could not be determined whether the hanger SC and 6C deficiencies had previously been evaluated and accepted by the licensee. The hanger installa-tion deficiencies were identified to the licensee as unresolved item 413/79-16-02, " Cable Tray Hangers Not Installed P er Drawings". High potential tests for cables 1*RN 501,1*RN 669,1*RN 668 and 1*EPE 501 had been completed, and the results were documented on DPC form 06060.
Within the areas inspected, no items of nonconformance or deviations were identified.
