the cable code defines the size, number, insulation type, and cable outside diameter while the system No. gives the description of the system.
The nondestructive test data reading are attached to either the
"TO" or "FROM" cards and list the cable No., Megger, Control No., calibration due date, reading, comments, and signature and date that the test was performed and reviewed by quality control inspection.
The inspector reviewed the Quality Control Megger Test Data Record Cards for the cables listed above under cable
termination and determined that they complied with the require-ments of the termination cards.
No items of noncompliance were identified.
4.
Electric Penetrations Unit l,and Unit 2 It appears that during the receiving and installation processes, the Westinghouse Electrical Penetrations have developed cracks in the potting of the penetration.
This has been identified by Bechtel Quality Control in the following noncompliance reports.
NCR No.
3104 3237 Penetration No.
,Unit 1W105A (Inboard)
2W106B (Outboard)
In addition to cracks in the potting, it appears that the pot-ting did not seal around some of the cables and some cables appear to have surface damage entering the potting material.
The licensee has not returned any of the penetrations to Westing-house as yet, and the investigation as to the depth of cracks, and the cable problems have not been started.
The licensee was informed by the inspector that if Westinghouse is going to perform a detailed analysis on returned penetrations, Region I will be notified as to the time, date, and location so that NRC personnel can be present during the investigation.
This item will be considered unresolved and will be examined during a subsequent inspection (79-16-01; 79-10-01).

General Electric PGGC S stem While performing field re-work as defined in tasks H)I WJEA, on modules 72C and 73C from "Plant Operating Benchboard OC653 (GE-H12-P853) Bechtel noted the following conditions of the equipment.
a.
Insert Module 72C Contact, spring, and cam fell out 'of switch HS000-49, and loose screws and parts were found when the metal barrier was removed for switch access rework.
b.
Insert Module 73C Internal wiring (14AWG) paralleling conduit numbers 15, 18, 19, 20, and 21 were damaged.
It appeared that damage to the insulation occurred due to routing of the wiring over sharp edges of steel and installation practices due to crimping.
Co It also appears that the insert module internal wiring appears to violate minimum six inch separation criteria as specified in the FSAR, Volume 7, Paragraph 3.12.3.4.2.6B.
Bechtel has identified the above nonconformances on NCR's 3748, 3760 and Management Corrective Action Report 1-33 dated April 27, 1979.
This matter continues to be carried as an unresolved item and will be examined during subsequent inspections.
6.
Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, items of n'oncompliance, or deviations.
Unresolved items disclosed during this inspection are discussed in Paragraph
and.
