l FINAL REPORT, REVISION 1 - DER 82-78 DEFICIENCY EVALUATION 50.55(e)

ARIZONA PUBLIC SERVICE COMPANY (APS)

PVNGS UNITS 1, 2 & 3 I.

Description of Deficiency i

During surveillance activity and random inspection of the Unit 2 Control Building Chiller Control Panels 2J-ECB-E02 and 2J-ECA-E03 supplied by 2

Carrier Air Conditioning, it was found that the electrical terminations did not comply with the visible inspection criteria for the Thomas &

Betts crimp lug terminations. This criteria is established by Thomas &

4 Betts Basic Criteria and Installation Procedures (TRM-1) dated June, j

1978. The visual defects include:

Terminations exceed 1/16" of conductor extending beyond the' barrel of the lug.

Conductor not exposed from barrel of the lug.

r Paper not removed from conductor prior to crimping barrel of the lug.

)

Lugs were reversed, preventing visual inspection.

II.

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 IE terminations utilizing crimp type lugs in'the subject 3

equipment shall be inspected to visual criteria which provide that the i

conductor shall be approximately flush with or protrude through the barrel approximately 1/16". ' Any connectors which do not meet this i

j criteria shall be repaired, as applicable, following the termination practices established in Bechtel Construction Specification 13-EM-306~.

j This condition will be corrected via the following Design Change

Packages:

lk 1-IR-004 2-1R-004 3-IR-004 1

In addition to reportability under.10CFR50.55(e), PVNGS Project considers the deficiency to be Reportable by the supplier under the requirements of 10CFR Part 21.

This report satisfies the reporting requirements specified under 10CFR21-21 (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 Carrier Air Conditioning requesting'their i

review for reporting under 10CFR Part 21.
