FINAL REPORT - DER 84-09 DEFICIENCY EVALUATION 50.55(e)

ARIZONA PUBLIC SERVICE COMPANY ( APS)

PVNGS UNIT 2 4

'I. Description of Deficiency 4

Eight cad welds, for cathodic protection ground connections, were made on ASME Section III piping (2" and 2-1/2" buried diesel fuel lines for the standby diesel generators) without a qualified welding procedure or any welding documentation. A review of this condition has indicated that it falls within the scope of.ASME Code Case N-328.

r I I .' Analysis of Safety Implications Since all the other conditions of ASME Code Case N-328 were met for the cad welding described above, the Welding Procedure Specification which'was issued for the corrective action applies retroactively to it.

This condition is evaluated as not reportable under 10CFR50.55(e) and/or Part 21; since, if lef t encorrected, it would not pose a significant safety hazard.

III. Corrective Action A. An approved Welding Procedure Specification (WPS PI-THERMIT, Rev. O, March 9,1984) has now been qualified to ASME Code Case N-328,Section III, Division 1, Classes 2 and 3. - This WPS will be used in performing all future cad welds to carbon steel (PI) pipe.

B. Case N-328 of ASME Boiler and Pressure Vessel Code,Section III, Division 1 (".nermit Brazing or Welding of Nonstructural Attachments) is being referenced in the Design Criteria Manesi ~and also included in the FSAR (Ref erence SAR Change Notice 1173 and Design Criteria Request No. 872).

C. All eight subject cad welds shall be inspected to the acceptance criteria of Visual Examination Procedure

. p'.

VE-BPC-1 (latest revision), referenced in Form 84. Form 84 will be revised to include the requirement that all cad welds are to be inspected in accordance with Procedure VE-BPC-1. These 8 cad welds are the only such brazed joints to have occurred on ASME Section III piping to date.
