the Piping and Electrical Departments. The inspector observed that audits of the Piping Department and the Welding Depart =ent had not been conducted on a monthly basis as required by GCP-1-2, Addendum A. Paragraph 2, Section C and that random sa=pling audits of the Electrical Department field drawing locations had not been conducted on a weekly basis as required by GCP-1-2, Addendum A, Paragraph 2, Section D.

cable and Racevav Installation During inspection of cable and raceway installation the inspector identified the following nonconfor=ing conditions:
.
a.
Cable Installation
'
During the inspection of the Cable Room and Control Room, the inspector found that the separation criteria insice Control Room cabinets and cable cross over areas were not being met.
The inspector also noted that barrier naterial used to maintain separation within cable trays carrying instrumentation and control cables did not pass through tees or around bends. Review of the
,
'QC checklist showed that the t:
- had been inspected and accepted without identification of failur>

t b.
.Racevwv Installation l
,
During the inspection of the cable tray hangers, the inspector found that the installed hardware was not in accordance with
,
the.equirements of UE&C drawing 9459.02-102474-E, Revision I.
c.
Engineering Instructions The Burns and Roe pull slips for cable pulls do not define the

Cable Identification
'
Cables leaving raceways and at intersections within racevays were not identified as required by Procedure ECP-3-2.
The inspector was informed that these nonconforming conditions had been identified during a licensee audit of electrical activities and confirned that they were included as findings
.
in GPU Audit Report 76-14.
This item (76-1902) is unresolved pending review of corrective action by an NRC inspector.
Tecuerarv Runs of Safety Related Cabh
,
During inspection of the cable room, the inspector rnted four safety-related cables, HH108C, EH1210, HH97C and HRlf.2C tied under a cable tray and tagged with a te=porary installation notice on the bundle. There is no procedure for pulling te=porary safety related cables and no controls to assure that no damage was done to the cable while in a temporary configuration. This fi'nding was t
identified during a licensee audit.
This item (76-19-03) is unresolved pending review of corrective
'
action by an NRC inspector.
Fire in ITE Motor Control Center - Series 5600
.
'
The licensee had reported a fire in ITE motor control center (MCC)
No. 11E3 on Nove=ber 22. 1976. Invesd.gation of thir fire indicates that during inserting of the combination st'arter/cf.re'u'it bisakeilidii a unit compartment one of the bifurcated" copper stiabs was misallised -
n1 ring a high resistance contact with the vertical bus bar. The copper stabs of the starter / circuit breaker module connects to the bus bars of the cabinet through slots in a fiber-glass polyester
'
'~~ sate-1 1 ithin the unit compartment.~
The heat generated at the
{
,
,
s t a'
ar contact was sufficien't' to ignite the fiberglass polysster ma: -
rithin the unit compartment. This fire also caused a cover
over the horizontal bus bars of the MCC to ignite and bers.

b.
Establish extent of cable da= age of safety related cables to MCC.
Esta*alish characteristics of materials used in the MCC.
c.
d.
Establish schedule for installation of replacement MCC.
This item (76-19-04) remains unresolved pendi'rg review by an NRC inspector of installation of replacement MCC and associated safety related cables.
7.
Short Circuit in GE MCC - 7700 Line
.
The licensee had reported a short circuit in GE MCC No. 21E3 on November 17, 1976.
- At the time of this inspection, the investigation was not co=plete i
but the following are considered to have contributed to the short circuit:
The power cables connect to the horizontal bus bars of the a.
cabinet through the top entry position. During connection of the power cables t3 the bus bar connectore within the
-
cabinet, one of the esanectors was bent toweds t' a rear of
,
the cabinet, thus reducing the air gap.
b.
Cors drilling of the floor above the MCC had been completed recently an ' a water / cement slurry had run down the conduits
.
and into tia bus bar conpartment of the MCC.
k h two workmen vere tagging wires within MCC 21EB, a third c.
. man working on cable trays nearby stepped on top of a cabinet
-
adjacent to the MCC. The weight of this nan on top of the cabinet apparently caused a slight move =ent of the vall of
'
Cabinet 21E3.
This movem'ent in conbination with the reduced air gap is considered to have been sufficient te have caused a short he'veen one of the bus bars and the metal cabinet.
The
'
short melted the vertical bus bar and the viring within the cabinet and also injured the two men working in front of the
-
cabinet.

The main breakers to the MCC vere tripped and power was removed from the MCC.
It was noted that the. ground fault relay was not in the circuit due to a -construction related condition.

.
B.
GPU Audits of Electrical Installation The inspector revie.e4 tha. records of the last two QA audits (Audit Reports 75-32 and 76-14) associated with electric cable installation, cable tray and conduit. These records confir=ed that the audits were performed and that deficiencies identified during these audits were documented and corrective action either was completed or in process c,f being acted on.
No discrepancies were identified.
9.
Bolt Thrend Enragement Insufficient engagement of bolt threads on flanged connectionn in the Decay Heat (DH) system had been identified as an unresolved iten.
(Inspection Report 50-320/76-01)

1976 which reviced specifications 2555-64 and 2555-72 to read
" Length (of thread) shall be sufficient to expose any visible portion of thread beyond the b maring surface of. the nut af ter
-
each assembly."
b.

.
piping systems) which had been revised August 3,1976 ti. add a requirement that proper thread engagement of bolted connections be verified.
Quality Control Inspection Report (QCIR) No. W-2372 which c.
verified t. hat thread engagement of DH flanges met the require-
.
ments of specification 2555-72 and ECM 1552 af ter corrective action.

2555-72 with resweet to field testing Discrepancies in specificationof the condensate storage tank had been ide it e:1.
(Inspection Report 50-320/76-08)
2555-72
..ich The inspector examined revision 52 to specification corrected the test requirements to identify Paragtaph ND-61J.O of ASME Section III, Winter 1971 Addenda as the appropriate requirement.
This paragraph in turn invokes the requirements of NC-6500 of the B&R memo dated September 16, 1976 statc. that the ASME III Code.
hydrostatic test was performed in accordance with the requirements of ASME Section IIT., Winter 1971 Addenda using the test procedure of NC-6540.
This item is resolved.

Insuection of Reinforcing Steel for Damage 11.
Minoc damage to reinforcing steel during chipping of concrete and i
lack of a requirement for inspection of the steel had been identi-fled as an une..olved item.
(Inspection Report 50-320/76-15)
The inspector examined the following documents:
Deviation Report (DR) No. 0605 with Supplements 2 and 3 docu-menting an inspection of the rebar in the fuel transfer tube a.
blockout and identifying the marks to be generally less than 1/16 inch deep vich seme da= age up to 1/8 inch.
Attached to the DR was Test Report No. P6.5549 by Pittsburgh Testing Laboratory (FIL) of a test on No.11 rebar with nicks

Incenolete Records of Preventive Maintenance Waiving of pre entive maintenance checks folleving turnover to test v
and startup group had been identified as an uneasolved item.
(Inspec-tion Report 50-32C/76-15)
Preventive Maintenance Specification SP-4 has been revised (TCN-2)
to add Paragraph 5.5 which requires that the date of operation shall be shown on the Preventive Maintena ce Card as a record of the equip-ment having been operated during the period.
This item is resolved.

Batterv Rocm Wiring and Lighting
Review of a possible requirement for use of explosion proof equipment l
in the battery rooms had been identified as an unresolved item.
(Inspection Report 30.-320/76-12)
-
.
By memo dated October 7,1976, B&R states that H7AC calculations indicate that during normal operation a minimum of 2 efs of fresh air is required tn eliminate a potentially hazardous atmosphere and that even under completely ait tight conditions a potentially hazardous atmosphere vould not be present until 12 days af ter cessation of all ventilation. Examination of the HVAC flow diagram showed that
,
the battery room ventilation system includes two, supply fans and an i
-
, exhaust fan.
This meets the dasign criteria.
