g FINAL REPORT - DER 82-43 DEFICIENCY EVALUATION 50.55(e)
ARIZONA PUBLIC SERVICE COMPANY (APS)
PVNGS UNITS #1 AND #2 I.
Description of Deficiency Quality Control surveillance and random inspection of Unit #2 Main Control Boards indicated there may be deficiencies with the Wiring Terminations as supplied by Comsip, Incorporated.
Inspection of the Thomas and Betts Lug Terminations completed by Comsip revealed the following visible items which do not comply with the Thomas and Betts Basic Criteria and Installation Procedures (TRM-1), dated June, 1978. The visible defects include:
e Paper insulation is visible around the conductor, inside lug barrel.
e Conductor is not visible inside lug barrel, e Jumpers cut short, stress in lugs at termination points.
e Lugs not fastened securely to terminal strip.
11.
Analysis of Safety Implications This condition is evaluated as Reportable.
If inadequately crimped lugs were left uncorrected, potential open or short circuits could jeopardize functioning of this safety-related equipment.
III.
Corrective Action All Class lE Terminations utilizing crimp-type lugs in the subject equipment shall be inspected to visual criteria which provide that the conductor shall be approximately flush with or protrude through the barrel approximately 1/16". Any connectors which do not meet these criteria shall be repaired, as applicable, following the termination practices established in Bechtel Construction Specifi-cation 13-EM-306.
This condition will be corrected via the following Design Change Packages:
10J-RM-091 and 20J-RM-091.
This condition will be precluded on the Unit #3 Panels by transmittal of this Report to Bechtel Supplier Quality and to Comsip for their increased inspection and verification prior to shipment.
l In addition to reportability under 10CFR50.55(e), PVNGS Project considers the Deficiency to be Reportable by the supplier under the requirements 10CFR Part 21.
This Report satisfies the reporting requirements specified under 10CFR 21-21(b)(3) with the exception of Sub-Part (vi) which requires the number and location (customers and/or facilities) of other possibly defective equipment. A copy of this Report will be transmitted to Comsip, Incorporated requesting their review for reporting under 10CFR Part 21.
