Site _To_ur_
Upon arrival at the site, the inspectors toured the containment building to ascertain general compliance with regulatory requirements, codes, standards and site procedures.
The emphasis of tour was to determine if Class IE cables were being provided with adequate protection from potential hazards such as missiles or pipe failures. The Class IE and associated circuit cables inspected appeared to be satisfactorily protected. During the tour the inspectors also examined a number of permanent attachment welds made to heavy sectioned structural columns
!
for compliance with AWS D1.1 preheat requirements. Review of weld l
records indicated that the welds were made utilizing welding procedure specifications qualified for welding without preheat in compliance with the rules of AWS D1.1.
No items of noncompliance or deviations were identified.
3.
Electrical (Components and Systems)
The inspector observed various facets of work activities in progress and completed relative to the installation of electrical equipmen.
<

-2-
This activity was performed to verify conformance with applicable specifications and QC procedure requirements. This included reviewing receipt inspection documentation, equipment identification and location, and reviewing construction QC inspection reports.
The following electrical components were inspected:
a.
125 VOC Batteries The inspector observed the storage conditions of the 125 VDC batteries associated with Battery Rack Nos. 3B007 (Train A) and 38008 (Train B). The electrolyte levels and temperatures were as required for rated performance.
Each battery installation included instrumentation and alarms, such as, a voltmeter, high and low battery voltage alarms, and ground detectors, b.
125 VDC Bus to Breaker No. 3BY03 - This breaker feeds battery charger 38001.
c.
Load Center (Distribution Panel) No. 3BZ d.
HPSI Pump No. 3P018 I
e.
Containment Emergency. Sump Pump No. 3HV9302 f.
Containment Fan'No. A072 g.
Class 1E Inverter No. S31807EY002 (Channel B)
h.
Boric Acid Makeup Pump No. T071 to Panel No. P174
'
No items of noncompliance or deviations were identified.
4.
Electrical Cables and Terminations The inspector examined work in progress and completed work on the
-
.
cable schemes indicated below for compliance with licensee procedures,
'
PSAR commitments and IEEE-384 Specific areas inspected included cable size, cable termination points, routing, separation and protection.

,
of panel 3L71-3F as actually installed.
However, the cable in question I
was properly installed and inspected by QA/QC as dictated by the appropriate wiring diagram, and the computer generated pull card was determined to be in error. The wiring diagram provides the acceptance criteria for inspection.
No items of noncompliance or deviations were identified.

Safety Related Components - Review of Quality Records
a.
The quality records for four safety related components were reviewed to ascertain whether these records reflect work accomplishment consistent with NRC requirements and PSAR commitments. The following four components were selected:
Component Serial Number
(1) HPSI Pump S/N 1075155 (2) Containment Spray Pump S/N 1075145 (3) Reactor Coolant Pump S/N 701-N-0561 (4) MSIV S/N 484769
