Licensee Action on Previous Inspection Findings (0 pen) Unresolved Item (50-445/79-06; 50-446/79-06, paragraph S.b.(2)):
Quality Control Requirements for Cable Tray Supports. The licensec has an ongoing inspection on non Class IE hangers with a final inspection on non Class IE hangers to be done by area prior to Hot Functional Testing.
The non Class IE hangers installed before March 1979 are being reinspected as seismic Category 1 including welding.
This item will remain open pending completion of this reinspection.
(Open) Infraction (50-445/79-19; 50-446/79-19): Failure to Follow Noncon-formance Procedures for Electrical Cable. NCR E-1570 has been revised to include proper identification of all the improperly color coded cable in the reel yard and installed. The disposition now properly addresses all aspects of the nonconformance description. All of the improperly color coded cable reels have been returned to the manufacturer and the four cables that were installed have been repulled with proper color coded cable.
QI-QP-11.3-15 " Electrical Cable Installation Inspection Procedure" has been revised (Revision 2) to include cable type and color verification. The procedure covering handling of nonconformance reports has been revised to include a review by the Quality Engineering Group to insure that the noncon-formance is properly described, the disposition is proper and complete and that all nonconforming materials are properly identified and controlled.
1732 047
This item will remain open pending implementation of the revised training program as committed in the licensee's response letter to IE Inspection Report 79-19.
(Closed) Unresolved Item (50-445/79-19; 50-446/79-19, paragraph 6.a.):
Cable Identificatica Deterioration. The licensee has contacted the cable manufacturers and determined that the observed deterioration was due to exposure to weather in the cable reel yard. The licensee has chosen two methods to correct the fading and peeling of the color coding in accordance with the manufacturers' recommendations:
(1) reapply color coding using recommended coating onsite; and (2) return selected reels to the manufacturer for recoating.
All cable reels that are susceptible to deterioration have been covered to prevent further deterioration due to exposure.
This item is closed..
3.
Site Tour The IE inspectors toured the Unit 1 and 2 Reactor Buildings and Auxiliary Building to observe construction activities in progress and to inspect housekeeping.
No items of noncompliance or deviations were identified.
4.
Electrical Systems And Components a.
Review of Electrical Instructions and Procedures The IE inspector reviewed the following procedures to determine compliance with 10 CFR 50, Appendix B; Chapters 3, 8, and 17 of the FSAR; and related IEEE and IPCEA standards:
QI-QP-11.3-4, Revision 10, " Exposed Conduit, Condulet, Electrical Box and Support Inspection" QI-QP-11.3-5, Revision 8, " Cable Tray Inspection" QI-QP-11.3-6, Revision 2, " Lighting Fixture Inspection" QI-QP-11.3-7, Revision 2, " Lighting Wire Installation" QI-QP-11.3-9, Revision 2, " Lighting Conduit and Box Installation" QI-QP-11.3-15, Revision 2, " Electrical Cable Installation Inspec-tion" QI-QP-11.3-16, Revision 2, " Class IE Cable Terminations" 1732 048

Observation of Work The IE inspector observed coupleted installation of cable tray, conduit, raceway support, and cables in the auxiliary building and control complex to determine physical compliance with FSAR, Craft and QC Procedures, and applicable IEEE and IPCEA Standards and Practices.
The IE inspector witnessed the installation of cable E0104300.
This installation was accomplished in accordance with QI-QP-11.3-15.
During this inspection, there were no items of noncompliance or deviations identified; however, the IE inspector had three areas of concern which were discussed at length with licensee represent-atives both preceding and during the exit interview.
(1) The IE inspector found several areas where the EEIs (Craft Work Instructions) did not agree with QIs (Quality Control Instructions).
All of the QIs that were reviewed during this inspection had b.mn revised during the last six months and many of them were in the process of being revised again.
The licensee advised the IE inspector that the EEIs were being updated as rapidly as possible.
At the present time the areas that conflict are not appli-cable to the work being accomplished. The licensee has committed to a complete review and update of these con-flicting areas in a timely manner, prior to their field use for safety-related work activites.
(2) During discussions with QA, QC and Craft personnel, the IE inspecter received different answers to the same questions concerning the use of cable lubricants in a conduit, the requirements for flexibility loops at transition points in a raceway, and what were transition point and bend radius 1732 049
requirements. This appeared to indicate a lack of communi-cation between QA, QC ani Craft personnel.
(3) The IE inspector became aware through discussions with the licensee that the Craft personnel were not receiving the same level of training and guidance as the QC personnel and that the two organizations did not appear to be operating by the same guidelines for quality.
The licensee and the IE inspector discussed these items of concern and the licensee committed to an immediate and complete review of commitments to preclude the possibility of problems as the electrical work accelerates. These three aspects of the electrical cable installation program will be considered an unresolved item pending completion of the licensee's review and subsequent IE inspection.
5.
Safety Related Piping - Units 1 and 2 The IE inspector observed the fitup and root welding of field weld FW-14 on line 2-CC-1-SB-035A-1 of the Unit 1 Component Cooling System for compliance with Welding Procedure Specification No. 11021 Revi-sion 3 and the welding of field weld FW-2 on line 3-CT-1-117-301R-2 of the Unit 1 Containment Spray System for compliance with Welding Procedure Specification No. 88021 Revision 5/ICN 4.
The fitup cleanliness was inspected on field weld FW-7 for line 3-CS-2-217-ISIR-2 of the Unit 2 Chemical and Volume Control System.
The welding of field weld FW-6 on line 16-CT-2-014-301R-2 of the Unit 2 Containment Spray System was monitored for compliance with Welding Procedure Specification No. 88023 Revision 7/ICN 1.
The IE inspector observed piping activities involving handling and installation of pipe spool RH-1-RB-01-2 for the Residual Heat Removal System of Unit I and storage and protection of pipe spool SI-1-RB-5A-2 for the Safety Injection System of Unit 1.
A review of the weld records was performed for field weld FW-1 on line 1 -SI-1-026-2501R-1 to verify that the liquid penetrant exam-ination had been accepted by qualified QC personnel. The weld was inspected to verify that the surface condition was suitable for liquid penetrant and radiographic examinations.
In the areas inspected, no discrepancies from the requirements of the welding procedure specifications; the piping fabrication construction procedure No. CP-CPM-6.9; storage procedure MCP-10:
or the ASME B&PV Code were noted.
No items of noncompliance or deviations were identified.

Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, items of noncompliance, or deviations. An unresolved item disclosed during the inspection is discussed in paragraph 4.
7.
Exit Interview The IE inspectors met vith licensee representatives (denoted in para-graph 1) and R. G. Taylor (NRC Resident Inspector) on October 11 and 19, 1979, and summarized the purpose, scope and findings of the inspection.
The licensee representatives acknowledged the statements and items of concern including those detailed in paragraph 4.
