Licensee Action on Previous Inspection Findings (Closed) Unresolved Item 79-18-03, Cable separation guidelines. The licensee has issued Revision 16 to the FSAR which allows a reduced separation in the cable spreading areas. This revision identified that Regulatory Guide 1.75 will be implemented. The inspector has no further questions. This item is closed.

Licensee Identified Items (50.55e))
a.
(0 pen) 395/80-14-01:
D. C. System Design.
On April 30, 1980 the licensee reported that the feeder from a safety-related 120 volt DC bus did not contain an isolation device as specified in the original design. The safety-related bus was feeding a nonsafety bus. A change has been initiated to feed the nonsafety bus from a non-
,

safety source. This item will remain open pending receipt of the licen-
!
see's final report and review by Region II.

-2-t b.
(Open) Item 395/80-14-02: Improper assembly of Containment Electrical Penetrations.
On April 30, 1980, the licensee reported that containment electrical penetrations were being improperly assembled. The following problems were identified:
1.
Cable adapter pins were being used instead of blinding pins.
2.
The wror.g size blinding pins were being used.
3.
Blinding pins left out.
QC had inspected and accepted the electrical penetrations.
These problems could have caused the pins to fail if left undetected. This item will remain open pending receipt of the licensee's final report and review by Region II.
c.
(0 pen) 395/80-14-03: ITE Speed Switches Insulation Failure.
The licensee reported on April 30, 1980 that ITE speed switches actua-J ting insulators were failing due to cracking. The problem appears to be caused by the switch knife blades striking the operating arm insulator.
However, no definite cause has been determined. The speed switches are used in both the service water and component cooling water systems.
The licensee has reported this problem under 10 CFR 50.55(e) and evaluated the problem as a reportable substantial safety hazard under 10 CFR part 21.
This item will remain open pending receipt of the licensee's final report and review by Region II.
d.
(0 pen) 395/80-14-04: Electrical tape Shelflife.
On April 30, 1980 the licensee reported the failure of the warehouse to keep track of the shelflife for insulation tape for safety-related electrical connections. Due to a related problem with insulated tape, all tape for safety-related 480 volt connections is being replaced.
Records were not adequate to confirm that the tape did not exceed its shelflife. This item will remain open pending receipt of the licensee's final report and review by Region II.
e.
(0 pen) Item 395/80-14-05: 480 Volt Safety-Related Breakers with Wrong
'
Current Transformers.
On April 30, 1980, the licensee reported that 480 volt breakers supplied by ITE were provided with the wrong current transformers. Current transformers (CT) rated at 225 amperes were provided instead of CT rated at 600 amperes. The licensee has reported this problem under 10 CFR 50.55(e) and evaluated the problem as a reportable substantial safety hazard under 10 CFR part 21. This item will remain open pending receipt of the licensee's final report and review by Region II.

(Closed) 395/79-30-03: Incorrect cable tray splice plates.
The licensee's letter of September 27, 1979, identified that all deficiencies were documented ou site nonconformance reports.
The nonconformances were reviewed and an inspection of the containment, auxiliary, control and intermediate buildings was made to verify the corrections. This item is closed.
6.
Inspection Followup Items (Closed) 395/79-09-01 Documentation of separation conflicts.
The licensee has issued revision 6 to FQCP 7.1.6, Installation of Exposed Conduct and Conduit supports. This procedure now incorporates the necessary documentation. This item is closed.
(Closed) 395/79-18-04, Safety-related cable separation in the Inverter cabinets.
The licensee has provided a fire resistive barrier by coating the cables with Quel-Pyre mastic. The licensee has qualification data on the Quel-Pyre Mastic. This item is closed.
(Closed) 395/79-32-01, Manufacturer's connection box support brackets on flow transmitters.
The licensee provided test data showing that the support brackets were not used as part of the qualification.
This item is closed. A new inspector follow-up item identified as 80-14-06, Tightness of connection box to transmitter inspection.
The licensee procedure for the inspection of instruments does not require a specific inspection step to verify the tightness of the box.

Instrumentation (Cables and Termination I) - Observation of Work and Work Activities The inspector selected the following safety-related instrumentation cables for examination:
RC-D-11A SW-U-51B RC-D-12A RC-D-14B RC-D-13B RC-U-1A SW-U-41A RC-U-2A SW-U-43A RC-U-24A Work and work records were examined in the areas of storage, handling identification, material control and installation.
Completed " pull" and
" termination" slips were reviewed to ensure that cable installation instruc-tions and inspections required by Field Quality Control Procedure (FQCP)
Section 7.1.1 and 7.1.2 were accomplished in the areas of maximum allowable l
pull tension, cable size, type, termination, routing, location, protection, I
separation, identification, loading and nondestructive tests.

Completed " pull" and " termination" slips were reviewed to ensure that cable installation instructions and inspections required by FQCP sections 7.1.1 and 7.1.2 were accomplished in the areas of cable pulling, cable size, type, termination, routing, location, protection, seperation, identification, loading and nondestructive tests.
Within the areas inspected, no items of noncompliance were identified.
10.
Instrumentation (Cables and Terminations II) - Review of Quality Records The inspector selected the safety-related instrument cables identified in paragraph 9 for a quality records review.
The records were examined to assure that the requirements of the FSAR and QAM were complied with in the areas of nondestructive examination, nonconformances and qualifications of QA and QC personnel.
Within the areas examined, there were no items of noncompliance identified.
11.
