Licensee Action on Previously Identified Inspection Findings (Closed) Unresolved (50-382/80-28): Reactor Turbine Control Board Wiring Separation. The unresolved item relating to control board wiring has been resolved as discussed in paragraph 3.b of this report.
The NRC inspector had no further questions on this matter.
3.
Safety-Related Electrical and Instrumentation Cables and Terminations a.
Observation of Completed and In-Process Work The NRC inspector traced out the total route of four safety-related (fuel Handling Building HVAC) instrumentation and electrical cables to ensure that the cables had been installed in accordance with FSAR, Ebasco specifications, LP&L procedures, F&M procedures, and industry standards. The cables were checked for routing, color coding, race-way installation, identification, separation, and correct size.
The following cables were inspected:
31231A-PB 31230A-PA 31228A-PB 31238E-SA No violations or deviations were identified.

Inspection of' Reactor Turbtne' Generator Control Boards The NRC inspector also inspected the Reactor Turbine Generator Control Boards (CP-1, 2, 7, 8, and 18) in the Main Control Room and the Reactor Turbine Generator Auxiliary Control Board (LCP-43)
located remotely from the Main Control Room. The Ebasco Engineering Field Change DCN-NY-IC-426, dated February 18, 1981, to the above control boaros as reflected on the following Ebasco wire trough detail "as built" drawings was reviewed:
1564-9160 R3, Rev. EF-2 1564-9298 R1, Rev. EF-1 1564-9301 R1, Rev. EF-1 1564-9333 R2, Rev. EF-1 1564-9336 R2, Rev. EF-1 1564-9338 R2, Rev. EF-1 The control board modifications, as ordered by DCN-NY-IC-426, correc.ed the physical clearance and separation of wireways / trough problems cited as an unresolved item during NRC inspection 80-28 on October 21-24, 1980. The conflict between the "as built" control board drawings and maintaining the required separation distances required Ebasco to investigate reasons why the control board supplier (Reliance) did not build in compliance with Ebasco's Procurement Specification LOU 1564.415. Specification LOU 1564.415 requires compliance to Industry Standards IEEE 323-1971, 344-1975, 383-194, 384-1974, and 420-1973 to meet Regulatory Guide 1.75, " Physical Independence of Electrical Systems," criteria.
The minimum internal control board separation distance between.
Class IE division cabling and non Class !E cabling has been estab-lished by analysis r,f the proposed control board installation by Reliance.
This analysis has been based on the tests performed to determine that flame retardant characteristics of the wiring, wiring materials, equipment, and other materials internal to the control boards are in compliance with IEEE 384-1974, Section 5.
Reliance has elected to employ the use of ba-riers (1/4" glastic -
flame retardant sheet stock, UTR grade 1494) in lieu of maintaining the minimum separation distances of 6 inches anc I inch as cited during NRC Inspection 80-28.
Ebasco Enginee-ing Field Change DCN-NY-IC-426, as implemented, now meets the internal separation requirements of Ebasco Procurement Specification LOU 1564.415.
The NRC inspector verified that the modifications to the control boards were in agreement with Ebasco Engineering Field Change DCN-NY-IC-426 and reflected accurately on the above "as built" drawings under Revision EF-1 and EF-2, respectively.
The NRC-3-

inspector also verified that the Engineering Field Change was implemented on site appropriately by F&M t. raftsmen under Reliance supervision, witnessed ansi signed off by Ebasco QA/QC, and observed by LP&L QA. Ebasco QA Audits 1383 (February 18,1981) and 1182 (February 21,1980) verified that DCNs were being implemented effectively and were programmatically in control.
No violations or deviations were identified.
