FINAL REPORT REPORTABLE DEFICIENCY 50.55(e)

ARIZONA PUBLIC SERVICE COMPANY (APS)

PVNGS UNITS ktl, 82 and f33 I. Descri tion of Deficienc Purchase Order Specification 10407-13-EM-017, Paragraph 4.6.15.4, requires that Class IE and non-Class IE wiring shall be terminated on separate uniquely identified terminal boards, separated from each other by a minimum distance of six inches (6").

During installation in Unit 7/1, six 480 Volt Loadcenter Xsolation Relay Cabinets, Numbers IE PGA-L31X, L33I, L'35I and IE-PGB-L32I, L34I and L36I received from ITE Gould on this Purchase Order have locations where the Class IE con-ductors come within six inches (6") of non-Class IE conductors.

Actual separation varies from two inches (2") to five and one-

'half inches (5@

Twelve other Class XE 480 Volt Loadcenter Isolation Relay Cabinets received fromt ITE Gould were inspected for this condition and ten of these units had similar deficiencies to that described'bove. The identification of these units are as follows:

2E-PGA-L31I, L33I; 2E-PGB-.L32I, L34I, L36I; 3E-PGA~L31, L33, L35'nd 3E-.PGB-L34, L36, XI. Anal sis of Safet Im lication This condition is considered reportable based on'the following considerations:

1. This condition is in.violationof Class IE requirements and if left uncorrected could possibly represent a safety significant condition.

2. This deficiency'was overlooked by the supplier's inspec-tion program and delivered to the. project jobsite for installation.

~ ~

f I

Final Report Page 2 III. Corrective Action The nonconformance will be dispositioned to repair the condition by the following methods:

1. Position the Class IE and non-Class IE Wiring Harnesses more than six inches (6") apart by installing additional supports and/or relocating the termination blocks.

2. If the above method is not possible or practical, a barrier satisfying Code requirements will be provided between the Class IE and the non-Class IE wiring.

This corrective action will be completed prior to system start-up of the identified units.

A copy of Deficiency Evaluation Report 80-41 has been trans-mitted to the supplier, Gould-Brown Boveri.
