FINAL REPORT - DER 82-41 DEFICIENCY EVALUATION 50.55(e)
_ ART. ZONA PUBLIC SERVICE COMPANY (APS)
PVNGS UNITS 1, 2 and 3 I.
DESCRIPTION OF DEFICIENCY During testing of class IE 4.16kv switchgear IE-PBA-S03 and IE-PBB-SO4. two (2) conductors were found pulled from the crimped area of the termination lug barrel (s), and some of tha crimped lugs within the equipment did not exhibit marks which identify correct use of crimping tools and dies.
The attached General Electric (GE) letter provides the criteria and corrective action for providing acceptable termination crimpt in switchgear furnished by GE under Bechtel specification 13-EM-009.
A followup random inspection performed by Bechtel Construction using GE criteria in Unit 3 switchgear (7 cubicles noted below) revealed that not all lug terminations were in compliance; however, no open circuits were apparent. In some cases, conductors were less than flush with the crimp connector barrel, and the ends of the wires were not visible under high intensity light and magnification.
SWGR CUBICLE TERM. BLOCK TER!!. POINT 3E-PBS-S03S RRF H1 3E-PBS-S03N RRF H1 3E-PBB-SO4L SC 11 3E-PBB-SO4L RRF X1 3E-PBB-SO4M SA 1

3E-PBB-SO4R SH 3
3E-PBB-504R DD 11 II.
ANALYSIS OF SAFETY IMPLICATION This condition is evaluated as Reportable. Connections with reduced contact area in termination lug barrels do not adequately assure the degree of electrical continuity required for reliable operations. If inadequately crimped lugs were left uncorrected, potential open circuits could jeopardize safety related functions of this switchgear.
.i -
$ n.
III. CORRECTIVE ACTION All vendor terminations ~ utilizing crimp-type lugs in switchgear
~
supplied by GE under specification 13-EM-009 shall be inspected-for compliance to GE's visual criteria:
"The conductor sitall be flush or protrude _through the' connector barrel up to approximately 1/16 inch."
Any connectors which do not meet this requirement shall be removed and have a new AMP connector installed in accordance with Bechtel's:
termination practices established in construction specification l EM-306 (including proper usage and traceability of crimping.
. tools.).
This condition will be corrected via the following Design Change Packages:
10E-PG-015 20E-PG-015 30E-PG-015 In addition to reportability under 10CFR50.55(e), PVNGS Project considers this deficiency'to be Reportable by the supplier under the requirenents of 10CFR Part 21.
Deficiency Evaluation Report 82-41 addresses 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 possible l'
defective equipment. A copy of this report has been sent to GE requesting their review for reporting under 10CFR Part 21, i
including number and location of all components supplied.

4-letters. The second item in your 2-25-82 letter concerned AMP, 7l e
connectors.
The conductor should be flush or protrude through the j
connector barrel up to approximately 1/16 inch. Any connectors which do not meet this requirement should have new AMP connectors installed.
