Dear Sir:

A preliminary written report and an interim report of a reportable deficiency under 10CFR50.55(e) was transmitted by References (1) and (2), respectively.

Reference (2) estimated that information from qualification testing would be available by August 1, 1980.

This information is summarized on the enclosed interim report.

The qualification testing is not complete due to difficulties encountered during its implementation.

It is now expected that this information will be finalized by November 15, 1980 at which time a complete report will be submitted.

The Stop Work order", issued. March 5, 1980, on installation of the Rockbestos Class IE cables has been partially lifted for out-of-containment installations as explained in the interim report.

A decision will be made by September 1,

1980 on the disposition of the remainder of the quarantined cable and the cable previously pulled.

Very truly yours, EEVBJr/BSK:skc Enclosure soosqae &9C)

REPORTABLE DEFICIENCY 50.55(e)

ARIZONA PUBLIC SERVICE COMPANY (APS)

PVNGS UNIT //1 INTERIH REPORT August 1, 1980 Problem 'and'Previous Notification The purpose of this report is to provide additional interim information required by 10CFR50.55(e) con-cerning apparent deficiencies relating to 600V copper power cable, delivered and partially installed in Unit 81 of the PVNGS.

A preliminary written report of this deficiency was transmitted by Reference (1).

An interim report was forwarded by Reference (2).

Reference (2) stated that qualification testing and evaluation would be complete by August 1,

1980.

A roach to Resolution of the Problem Please refer to Reference (1) which documents our approach,to the resolution of this problem.

XII Status of Pro osed Resolution Class IE multiconductor cable with insulation repairs manufactured after October 1, 1979'is'ualified per IEEE-323-1974 and is released:for installation out-of-containment.

Steam line break/loss of coolant accident (SLB/LOCA) tests are being conducted.

Sufficient in-formation should be available by mid-October, 1980 to determine if this cable can be installed inside con-"

tainment.

Class IE multiconductor cable with insulation repairs manufactured before October 1,

1979 and all single conductor Class IE cable with insulation repairs has been undergoing aging analysis to 'establish at least a 40-year qualified life for out-of-c'ontainment use per IEEE-323-1974.

The scheduled completion date for this phase of testing is August 18, 1980.-

SLB/LOCA tests are scheduled to be completed in mid-September, 1980 for in-containment qualification.

Interim Report August 1, 1980 Page 2

IV Reasons for Dela of Final Re ort The final report is delayed in order to await the completion and evaluation of qualification testing.

The final report is delayed because of the time involved to develop Arrhenius plots for the insu-lation repair material as noted in Section III above.

V Pro'ected Com letion of Corrective Action and Submittal Date of the Final Re ort Class IE multiconductor cable with insulation repairs has successfully completed out-of-containment quali-fication.

Qualification for out-of-containment installation of single conductor cable with insulation repairs is scheduled for completion by August 18, 1980.

Disposi-tion for all out-of-containment cable installation is expected by September 1, 1980.

SLB/LOCA testing for all cable should be completed by late October, 1980.

A final report will be submitted by November 15, 1980.
