2.
Implementation of the Electrical QA Program
.
The RIII inspector discussed, with the Hatfield Electric Company QA Manager, the established program to stop work when an uncontrolled condition warrants such action.
The QA Manager stated that only one
"Stop Work Order" had been issued to date. That order, dated April 30, 1979, was concerned with the calibration of torque wrenches which were used for the installation of concrete expansion anchors.
Fer the QA Manager's memo of June 18, 1979, the stop work order was lifted.
The Hatfield QA Manager indicated that the implementation of the above order identified that the authorities of the Hatfield project manager and QA manager required clarification. Therefore, the authorities concerning stop work orders were more clearly defined.
The QA manager will now initiate an order when deemed necessary and discuss the context (impact) with the project manager. Any conflicts in the initiation of stop work orders will be expeditously resolved by the president of Hatfield Electric Company. Decisions concerning quality will be made independent of the impact of cost and scheduling.
No items of noncompliance were identified.
3.
Observation of Electrical Work Activities
".he RIII inspector observed installed Unit I cables ICC001 (5KV a.
power) and ICS019 (control). The raceway internals for the above cables were free of hazardous debris and sharp edges.
Conduit bushings and cable supports (grips) were appropriately installed. The raceways were temporarily identified.
The cables had no apparent damage.
Cable No. ICC001 was properly identified and routed in accordance with the Cable Pull Card.
A Cable Installation Inspection Checklist, Form HP-101, was completed to document the QC verification of the installation requirements of cable No. ICC001.
Cable No. ICS019 was incor-rectly identified at both cable ends. The cable routing was as specified on the Cable Pull Card of cable No. ICS019 except that the excessive cable, pulled to allow termination, extended into raceway which was not scheduled. The licensee stated that cable No. ICS019 had been properly re-identified and reworked to the proper termination points, during the NRC inspection period.

The fastallation requirements of cable No. ICS019 were not
'
verified by QC and therefore were not documented. The Hatfield QA Manager stated that all safety related (Class 1E) cable installations were not required by the current procedure to be verified (inspected) by QC. No criteria had been established to identify which cables or cable installation activitie,s would be inspected by QC. The Hatifield QA Manager also stated that the Cable Installation Procedure No. 10 was currently being revised. The licensee stated that instructions were currently being developed to revise the cable installation inspection requirements. Where necessary, cable installation inspection activities would be backfitted. The revised ir.stallation procedure, cable installation inspection requirements, and backfitting activities will be re viewed during a subsequent inspection. This matter is unresolved.

b.
The RIII inspector observed the complete in process installation of electrical penetration No. IAP85EA (including part of the final torquing of the flange bolts). The penetre. tion was installed with care and precision in accordance aith the step-by-step requirements of Conax Manual No. IPS-370, Rev. B, dated March 16, 1979. The penetration was located per Sargent and Lundy drawing No. 6E-1-3503, Rev. A.
A Hatfield QC inspector was present during the installation activities. The inspection activities were documented on checklist Form HP-121.1, Rev. O.
Hatfield Nonconformance Report No. 66 dated July 6, 1979, was written to identify indet!stions in two of the penetration cables.
c.
The RIII inspector took a thorough tour of the Unit 1 and Unit 2 auxiliary buildings to asse-: the overall electrical construction status.
No items of noncompliance were identified.
Unresolved Items Unresolved items are matters about which more information is required in order to determine whether they are acceptable items, items of noncompliance, or deviations.
An unresolved item disclosed during the inspection is discussed in Paragraph 3.a.
Exit Interview The inspector met with licensee representatives (denoted under Persons Contacted) at the conclusion of the inspection on July 6, 1979.
The inspector summarized the purpose and findings of the inspection.
The licensee acknowledged the findings reported herein.
