Battery Rooms Identification The twelve doors associated with the Emergency Switchgear of both units 1&2 were identified as " Emergency Switchgear Room". Similiarly the ten doors associated with the station batteries were identified as " Battery Room". Neither the unit nor the division or channel were identified. This lack of unit, division or channel identificat'
is a potential human factors problem. The l'consee has reviewed thi ancern and they plan to provide further identification to resolve this concern.

Based upon the licensee's proposed corrective action this item is closed.
2.2 (Closed) Unresolved Item (86-09-02) Motor Operated Valves Deficiencies were identified in the long term storage of motor operated valves (MOV). The inspector's concern was that the licensee assure the following as a part of the licensee's rework program for MOVs:
The location of all MOVs have been identified.
- That all MOVs have been or will be scheduled for
rework.
The proper storage will be maintained after the valves
are reworked.
The inspector reviewed the following types of documents for eight(8) MOVs.
The specific documents reviewed are listed in Appendix A.
Field Inspection Reports
Maintenance Action Cards
Long Term Maintenance Action
Valve Disassembly / Reassembly Record
In addition to the above review, the inspector performed a visual inspection of these valves to ascertain whether they were being maintained in accor-dance with the licensee's procedures.
The inspector concluded from the above that this item is closed.
3.0 Procedure Review The licensee's documents associated with the procurement, storage, installation and inspection of the class 1E electric system components including cabling were reviewed by the inspector.
This review was to ascertain whether the technical elements of the licensee's safety analysis report (SAR) and NRC requirements had been ade-quately translated into applicable documents. Also, to determine if the construction specifications, drawings, work procedures and instructions were of sufficient detail and clarity to perform and control the work.
The specific documents reviewed during this inspection are listed in Appendix A.
No deficiencies were identified.

4.C Record Review A sample of licensee records, associated with the class 1E electric systems was reviewed by the inspector. These records are listed in Appendix A.
This review was to ascertain the effectiveness of the licensee quality assurance program in the area of procurement, storage, work activities and inspection of the class IE electric systems to assure that the systems and components perform their safety-related functions.
No deficiencies were identified.
5.0 Electrical Components and Systems - Work Observation The inspector observed work in progress and completed work to determine whether activites related to safety-related electrical systems and com-ponents are being controlled and accomplished in accordance with NRC requirements, safety analysis report (SAR) commitments, and licensee
,
procedures.
The following observations were made of the installed class IE components and systems observed by the inspector:
,
The components were identified.
- Flame retardent dust covers were in place.
- Flame retardent plywood enclosures were installed over
electrical components.
Electric space heaters were energized.
- Components were installed at the correct location, with the correct
orientation.
Electrical separation was maintained
No violations were identified.
6.0 Electric Cable - Work Observation
l The inspector reviewed activities related to safety-related cables for systems to determine if they are controlled and accomplished in accordance with NCC requirements, safety analysis report (SAR) commitments and licensee procedures.
This included direct observation and independent evaluation of work performance, work in progress and completed work. The documents used during this inspection are listed in Appendix A.

6.1 Storage
,
The following storage attributes were observed by the inspector:
The Q-listed permanent plant cables were stored in a separate cable
yard from nonsafety-related cables.
Q cable identification was visable in all areas of the storage yard.
- The cable was stored above the concrete laydown area to preclude
contact with surface water.
Cable ends were sealed with tape or end caps.
- Master cable reels were identified both with the manufacturers metal
tag which described the cable on the reel including the purchase order and a Bechtel metal tag which also provides cable identifica-tion and traceability back to the purchase order.
- Sub cable reels were identified by Bechtel metal tags.
Bechtel QC records were reviewed for master cable reels, 807-AJ, 807-AK, 807-AL, which included the following:
Certified manufacture test reports.
- Certificates of Compliance.
- Bechtel QA acceptance.
- On-site receiving inspection and QA acceptance
The above information was used to establish traceability of sub reels, T24-AC, W30-AD, S33-AB, to their master reels. The information on the sub reels was provided on the Bechtel permanent log as required by Procedure CP-E-2.
No deficiencies were observed concerning cable storage.
6.2 Cable Installation i
Recorded data for several cable installations was reviewed for confor-mance with the requirements of specification 8031-E-1412. The calculated maximum cable pulling tension and sidewall pressure for the installed cables was compared to the data recorded during the installation.
For the installations reviewed the data recorded during the installation indicates that the pull tension and side wall pressure are less than the design limits.
7.0 Exit Interview An exit interview was held on October 17, 1986 with members of the licensee staff, denoted in paragraph 1, at the conclusion of the inspec-tion. The inspector summarized the scope and findings of the inspection at that time.
