Licensee Identified Items (50.55(e))
(_ Closed) 395/79-30-07: Lightninr Arrestors. On September 7, 1980 the a.
licensee informed Region II of a, aficiency in 480 volt switchgear lightning arrestors which resulted in low switchgear megger readirigs.
The licensee's final report to Region II dated February 11, 1940, provided the licensee's evaluation and corrective actions for this matter.
The suspect lightning arrestors were returned to the vendor

for testing which revealed a crack in the lower seal of four arrestors that allowed moisture to get into the arrestors. Additional vendor testing revealed that, although temperature effects on the insulation would effect resistance readings, there is no impairment of functional operation. The inspector reviewed the licensee's corrective actions, vendor correspondence, and the final disposition for Start-up Field Report number 1076 and has no further questions. This item is closed.
b.
(Closed) 395/80-02-01: 480 Volt Motor Termination Taping.
On September 18, 1979, the licensee reported to Region II a potential problem involving the use of unqualified insulating tape on 480 volt motor terminations.
NCN 770E was dispositioned to reterminate and remove the unqualified tape from suspected motors.
On January 8, 1980, the licensee informed a Region II inspector that during the performance of corrective actions for NCN 770E, NCN 884E was issued which documented the use of incorrect friction tape on 480 volt motor terminations. NCN 884E required that all 480 volt motor terminations be remade under SFR number 2070. The inspector reviewed completed corrective actions identified in the licensee's final report to Region II dated February 7, 1980, and has no further questions. This item is closed.
c.
(Closed) 395/80-05-04: Deficient Conduit Support Installations.
On February 4,1980, the licensee reported a " cold spring" deficiency in electrical conduit support installations. On February 11, 1980, the licensee provided a final report to Region II on this matter. The
,
inspector reviewed the licensee's final report and corrective action
,
for this item as documented and dispositioned on NCN 700E. All actions are complete. This item is closed.
d.
(0 pen) 395/80-10-02: Deficient motors for service water booster pumps
. A and B.
On March 31, 1980, the licensee reported improper operation of service water booster pump motors due to improperly installed (not welded and misaligned) stator spacer bars. On April 22, 1980, the licensee issued a final report on this matter which the licensee evaluated as a substantial safety hazard as defined by 10 CFR Part 21.
The inspector reviewed the licensee's final report and completed correc-tive actions for this item as documented in SCE&G QA Surveillance Reports (numbers 38043, 58052 and 6809) and NCN 56. The pump motors were returned to the factory for repair. A licensee representative witnessed completed rgpair, assembly and testing of the pumps at the vendor facility. This
,
item will remain open pending successful operation of the reinstalled pumps.
e.
(Closed) 395/80-14-02:
Improper assembly of containment electrical penetrations. On April 30, 1980 the licensee reported improper blinding pen installations in the plug assemblies for containment electrical penetrations. On May 22, 1980, the licensee issued the final report-on this matter.
Specific problems identified consisted of the wrong

size blinding pins, omission of blinding pins, and male adapter pins installed in lieu of blinding pins. Blinding pin problems were docu-mented on NCN 1006E which provides for inspection, repair and reinspec-tion of the plugs. NCN 1006E corrective actions have been completed for all except three electrical penetrations. The inspector reviewed the licensee's final report and corrective actions reported on NCN 1006E and has no further questions. This item is closed.
f.
(Closed) 395/80-14-04:
Electrical tape shelf life.
On April 30, 1980, the licensee reported the failure of site procedures to address the shelf life of tapes used for 480 volt power terminations inside the containment building. On May 27, 1980, the licensee issued the final report on this matter. The inspector reviewed the completed corrective actions identified in the licensee's final report to assure adequate disposition of this matter. Licensee corrective actions are complete. This item is closed.
g.
(open) 395/80-21-01: Diesel generator rocker arm prelube oil pump.
On June 27, 1980, the licensee reported to Region II a possible failure of the diesel generators to start as a result of flooding if the rocker arm prelube oil pump operated continuously while the diesel was in the standby position. On July 21, 1950, the licensee provided a final report on this matter. The licensee has evaluated this matter substantial safety hazard as defined by 10 CFR Part 21.
The as a licensee plans to modify the pump controls to allow pump operation for a short period each day. This item will remain open pending completion of licensee corrective action and review by Region II.
6.
Inspector Followup Item (IFI)
a.
(Closed) 395/80-02-03: Termination requirements for electrical pene-tration assemblies.
The inspector reviewed SCE&G QA Surveillance Report number 127924 and associated NCR's which documented problems and corrective actions encountered during installation of electrical penetration assemblies. Problems identified included damaged grommets, incorrect drilling template, unsatisfactory nut-to-mounting bolt engagement, nickel plating coming off studs, plug insulators drilled wrong, incorrect plug assembly, deburring shot inside female connectors, QC verification after installation, and improper field installation.
The licensee has completed corrective actions for the deficiencies which were adequately dcrumented and dispositioned on NCN's.
The inspector has no further questions on this matter.
This item is closed.

is verified and documented on QC Instruction forms MS-2-1, MS-6-1 and ES-1-1.
Although discrepancies were identified during the review of plant
,
equipment maintenance logs, Corrective Action Report (CAR) number 41 (subse-quent to maintenance log dates) resulted in changes to the licensee's preventive maintenance program which corrected deficiencies of the type i
'
identified on the equipment maintenance logs. The corrective ac'. ?on removed the responsibility for maintenance frcm the area superintendent and estab-
,
'
lished a new group to handle preventive maintenance for both electrical and mechanical equipment.
No discrepanices were identified in the maintenance logs dated after the closing of CAR-41 on April 25, 1979. This matter was previously addressed in IE Report 50-395/78-30.
Within the areas examined, there were no items of noncompliance identified.
