DETAILS 1. Persons Contacted Principle Licensee Employees

• P. Barnes, Regulatory Assurance Supervisor

• Gnoth, Assistant Construction Superintendent

• D. Brown, Quality Assurance Supervisor

• J. Smenter, QA Engineer P. Zolan, QA Engineer

• D. Cecchett, Regulatory Assurance

• J. Phelan, PFE Electrical Supervisor W. Lang, Projection Construction Department Contractor and Other Personnel C. Hart, Site QA Manager, LK Comstock J. Janek, Engineering Department, LK Comstock

• Denotes those persons attending exit intervie The inspector also contacted other persons in the engineering, quality and construction areas during the course of the inspectio . Licensee Action on Previous Inspection Findings (Closed) Open Item (456/8402-09; 457/84038-09): Licensee evaluation of Cable Separation Conflict Reports (CSCR). The inspector reviewed Surveillance Report 4434 that documented the completion of the licensee's evaluation. The backlog of CSCRs has been depleted. The cables above Panel IPA 01J have been trained and tie wrapped. LK Comstock's

Procedures 4.3.8 and 4.3.9 have been revised to require Comstock to compare each CSCR to the S&L Interface Review Report (IRR) for both six-inch and twelve-inch separation violation The inspector verified that Comstock personnel were trained to the revised procedures. The l evaluation and corrective action is considered to be adequat (Closed) Severity Level IV violation (456/84044-03; 457/84040-03):

General Electric switchboard wire not qualified for use in harsh environments used in plant switchgear. The inspector reviewed the

, licensee's corrective action documentation attesting to the replacement

'

of GE switchboard wire, GE SI 57275, with Rockbestos Firewall SIS wire in locations identified as harsh environments. This violation is considered j to be close (Closed) Severity Level IV violation (456/86015-02): Failure to write a Revision / Work Request (RWR) for Revision H of Drawing 20E-1-4687H. The inspector reviewed LK Comstock (LKC) RWR 13495 that had been issued to track Revision H to Drawing 20E-1-4687H. The RWR had been complete LKC Procedure 4.3.16 Revision G, " Revision / Work Request of all Electrical Equipment," requires an independent review of marked up drawings and for

LKC engineering to maintain logs to track the incorporation of drawing revisions. LKC Work Instruction WI 4.3.16-01," Walk Down Inspection of Safety Related Electrical Drawings," is completed. Sargent and Lundy completed an additional walk down inspection of electrical drawing revisions on September 2, 1986. This item is considered to be close (Closed) Severity Level IV violation (456/86015-01): Wiring of Limit Switch 14-14C of Valve IS001A was not in accordance with applicable drawings while the QC checklist indicated that the wiring was in conformance with applicable drawings. The inspector verified that the wiring had been corrected to conform with the latest drawing revisio The conductors had been spared. To prevent recurrence of this deficiency, LKC Procedure 4.3.16 was revised to require LKC engineering to initiate and maintain a tracking log to control the status of wiring diagrams and drawing change (Closed) Open Item (456/85021-03; 457/85022-03): Review of ten percent overinspection program for requirement to expand a sample when unacceptable indications are identified. The inspector reviewed CECO BRD 4638, December 29, 1980, which requires the inspection sample to be increased an additional fifteen percent when deficient welds are identified during the ten percent overinspection. Pittsburg Testing Laboratories (PTL) Procedure IS-BRD-27-01, "PTL Site Instruction for Overinspection Program," states that sample size may be raised or lowered depending on identified trend The inspector also reviewed PTL reports 851V4, 860VW, 885VW, 948VW and 969VW; each of these reports documented an increase of sample size from 10% to 25% as a result of unacceptable weld indications being identified during the 10%

overinspection. This aspect of the overinspection program functioned adequatel (Closed) Unresolved Item (456/86015-03): Lack of housekeeping and preservation control The inspector's examination of Valve LRE9170 revealed that the lcose conductor on the limit had been properly tightened. The red / black conductor at Terminal 11C of Valve ICC9413A has been reterminated and rerouted to avoid motor grease. The grease leak on the limitorque has been repaire The limit switch housing and bracket laying against the copper tubing to actuator of Valve ICS010A has been removed and the tubing repaire Visual inspection of these items determined that previously identified issues no longer exis . 10 CFR 50.55(e) Reports (Closed) (456/83012-EE; 457/83012-EE): Failure of Anaconda flexible conduit jacke Flexible conduit with split jackets has either been replaced or repaire Repairs were performed according to Sargent and Lundy Standard STD-EB-146-B/B and Drawing 0-3390A. The repair method prescribed in the standard and drawing is to wrap the conduit with two half lapped layers of Okonite T-35 jacket tape. The inspector reviewed

4. Review of Quality Records The inspector reviewed quality records relative to instrument components, systems, cables and termination Specific components and circuits for which quality records were reviewed are: Instrumentation circuits and terminations:

1AF074 1AF081 IDG167 1MS594 IPR 168 1PR175 1RC434 1RC436 1RF017 1RY334 1NR199 INR197 1DC037 1DG180 1MS095 Limit switch terminations for valves:

1RE9170 1CS010A ICC9413A Panels: IPA 33J The inspector also reviewed seismic and environmental qualification records for IVA01J through IVAISJ, OHS-VA511 through OHS-VAS40, IVA01J, IVA09J, IVQ11J, OV21J through OVA 245J, and IVA12J/13J. Records reflect that size and type of cables were installed as specifie Location and routing of raceways and conduit provide for necessary separation, identification is adequate, and records of cable pulling confirm that pull procedures were followed including pull tension calculation Inspection records confirm that deficiencies have been satisfactorily dispositioned and reviewe The records confirm that required material characteristics, performance tests, and qualification testing requirements were met. Components were adequately stored and maintaine Racks, panels, and cabinets were properly installed and the required inspections performe No violations or deviations were identified in this are . Exit Interview The inspector met with licensee representatives (denoted in Paragraph 1)
