FINAL REPORT - REVISION 1 - DER 83-43 DEFICIENCY EVALUATION 50.55(e) l.
ARIZONA PUBLIC SERVICE COMPANY (APS)
PVNGS UNIT 1 I.
DESCRIPTION OF DEFICIENCY During startup testing activities, the class IF. Auxiliary Relay Cabinets furnished by Harlo Corporation were found to have some terminations which did not conform to AMP crimping criteria. The deficiencies consist of the conductor not being visible throuch the barrel of the termination and the conductor interfering with e termination screw.
Identification of the affected equipe'
.n Unit 1 is as follows:
1-E-ZAA-C01 1-E-ZAB-C01 1-E-ZAA-C02 1-E-ZAB-CO2 1-E-ZA A-CO3 1-E-ZAB-CO3 1-E-ZAA-C04 1-E-ZAB-C04 1-E-ZA A-C05 1-E-ZAB-C05 1-E-ZAA-C06 1-E-ZAB-C06 The Harlo Corporation was contacted concerning this condition. The attached letter from Harlo Corporation provides their acceptance for using Bechtel's termination criteria per specification 13-EM-306.
At this tiac, Auxiliary Relay Cabinets for Units 2 & 3 are not inspected. An inspection of relay cabinets in Units 2 & 3 will be made at a future date and NCR's referencing this DER will issued for rework as deemed necessary.
II.
ANALYSIS OF SAFETY IMPLICATIONS This condition is evaluated as reportable.
If-inadequate crimped lugs were left uncorrected, potential hazards'of open circuits could occur which could jeopardize the functional requirements of safety b
related circuits.
III. CORRECTIVE ACTION All class 1E and Non-1E Auxiliary Relay cabinets. supplied by Harlo Corportion (Units 1, 2, & 3) shall be inspected for compliance per-the following criteria. The terminal lug connection.to the conductor is acceptable if the conductor is visible ~and underneath the crimp connection (i.e.; approximately.within 1/16".from the face of the barrel). -In cddition, the conductor extending beyond the barrel of the connector does not pose a. problem unless it interferes 4
with the termination screw, in which case it should be cut back.'
jp'
.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 13-EM-306 (including proper usage'and traceability of cramping tools).-

s sJ Final Report DER 83-43 Page 2 This condition in Unit 1 will be corrected by dispositioning NCR SE-1574 as " Rework". The condition in Unit 2 & 3 will be corrected via NCR's to be issued at a later date. All future NCR's generated as a result of this problem will reference this' DER.
In addition to reportability'uncer 10CFR50.55(e), Bechtel PVNGS Project considers the deficiency to be reportable under the requirements of 10CFR Part 21 by the. supplier.. Deficiency Evaluation Report 83-43 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 -defective. equipment. A copy of this report is being sent to Harlo Corporation-requesting their review for reporting under 10CFR Part 21 including number and location of all components supplied.
