Bechtel Construction Specification No. X3AR01, Section E9, Cable Installation and Cable Termination, R22 The inspector reviewed the above listed electrical work activity specification, procedures, and drawings to determine if the most recent revisions were used and in agreement with the SAR. Procedures were also examined to determine if they adequately described critical

' points, methods of installation and test hold points which properly reflect design inten Within this area, no violations or deviations were identifie Field Inspection Cable stored at the reel yard was observed being removed from the purchased reels, cut to predetermined lengths and either coiled in a Figure 8 configuration or placed on dummy reels of proper reel diameter to avoid twisting, kinking or violating the minimum cable bending radius The following cables were observed:

violations or cable kinking were observed during these cable pull The inspector verified that. multiple small clamp-on rollers were used properly and that free air space from tray-to tray, conduit to tray, tray or conduit to equipment did not exceed three fee The inspector did not notice any sharp tray edges requiring additional edge protectio ,

The inspector witnesseo the termination splicing of power service cable No. 2AB1513HB to nuclear service cooling water motor L 2-1202-W4-001-M03. This process utilized Raychem's Nuclear Motor Connection Kit (NMCK-4V-35-00). All work was accomplished satisfactorily in ' accordance with the vendors motor connection installation instructions which accompany each ki The inspector also accompanied an EQC inspector during his inspection of the following completed cable conductor terminations located in various panels and cabinets in the Control Buildin !

of this wiring diagram identifies two cables with the identical

cable number (2ACDPUAXA-2) entering panel 2-1623-05-001, with each cable's conductors being landed on different terminal points. The

'

EQC inspector found only one cable terminating in the panel and ,

immediately proceeded to check with field engineering to find out if l there were any changes to the controlled drawing. Field engineering l identified that Revision 1 to the wiring diagram deleted the second cable; consequently, the cable terminations were correct as installed. Subsequent checking by the NRC inspector with document control personnel verified Revision 1 was current, and review of all other drawing revisions utilized determined this to be an isolated case of no safety significance. All conductors for the above cables were found to be lugged correctly and landed of the proper terminal points.

The inspector accompanied two EQC raceway inspectors during their inspection of miscellaneous segments of conduit assemblies, pull and termination box installations, and their anchorage These items were inspected to verify proper size, type, location, separation, identification / color coding, routing, and anchorage in accordance with design drawings and procedure requirement Raceway installation work inspected included EE 580 Card Nos 2NE444KSJ25, 2NE454RX003W, 2NE454RS022, and 2NRJB4816. A discrepancy punchlist item (Log No. EL13P-4330) was written by EQC for electrical ,

termination box 2NEJB4816 for #14 bolts not being torqued and a #4 anchor bolt that did not achieve minimum (60 inch pounds) torque capacit Field observations and discussions with randomly selected electrical

. contractor and GPC EQC personnel were conducted by the inspector to verify proper electrical work activity program implementatic s. The  :

inspector concluded that the craf t personnel possessed the rez91 red knowledge, skill, and training to perform their assigned tasks and were accomplishing their tasks in accordance with approved procedure The inspector examined the Cleveland Electric (CE) cable termination i

certification log dated February 9, 198 The inspector also ;

verified the training and certification records for four termination -

electricians that were observed during work and found them qualifie Additionally, the training and testing records for eight observed '

cable pullers were examined and found satisfactory.

1 Within this area, no violations or deviations were identified.

, c. Quality Control ,

The inspector reviewed the following inspection records generated for ,

the above observed electrical activities to determine their adequacy, whether deficiencies submitted by the QC inspection personnel received proper corrective action as applicable, and if work and work controls were adequate:

Raceway Installation Cards and Inspection Reports Equipment Installation and Associated Support Cards Conduit Installation and Associated Support Cards Discrepancy Punchlist Log No. EL13P-4330 Cable Installation Cards and Inspection Reports Termination Installation Cards and Inspection Reports EQC Inspector Certification and Qualification Records The inspector reviewed applicable QC procedures (paragraph 5.a) to determine if the frequency, timing, and acceptance criteria for the subject inspections were adequat The number of EQC inspectors provided for the coverage of electrical work activities was satisfactory. Discussions were conducted with various EQC inspectors to determine 1f their knowledge was adequate and to determine whether their findings and concerns received proper management attentio . . . - . . -- _ . . ., - - - - --- - - - - - -

j The inspector reviewed the last two QC Deviation Trend Reports (87-6, 88-1) and the most recent Inspection Attribute Trend Report (88-1). l No significant trends were identified in the electrical disciplin Within this area, no violations or deviations were identified, i Materials and Equipment e.

The inspector examined certificates of conformance, test reports, and receipt inspection data for purchase orders PAV 3718 and PAV 3080 regarding cable observed terminated. The electrical cable suppliers

'

were found to be on Bechtel's Approved Evaluated Supplier's List dated January 31, 1988. An examination of the electrical' cable

torage conditions in the reel yard and power block were sati sf acto ry. All torque wrenches used by EQC for cable splicing operations and bolted electrical conduit / equipment support functions

were observed to have current calibration stickers, j
