o. INTERIM REPORT - DER 83-83 POTENT 1AL REPORTABLE DEFICIENCY ARIZONA PUBLIC SERVICE COMPANY (APS) PVNGS UNIT 2 I. POTENTIAL PROBLEM Pipe support drawing 13-SI-193-H008 Rev. 5 and specification 13-FM-204 Rev.12 require the installation of an ITT Grinnell Sway Strut Assembly Size No. 7 for item 61 of the drawing. During a field engineering inspection it was discovered that a Corner & Lada Sway Strut Size 7 was installed and accepted. The required design load for the sway strut assembly is 85,895 lbs. The ITT Grinnell Sway Strut Assembly Size No. 7 has a Level D maximum load rating of 86,500 lbs., whereas the Corner & Lada Sway Strut Size 7 has a level D maximum load rating of 39,480 lbs. II. APPROACH TO AND STATUS OF PROPOSED RESOLUTION Noncomformance Report PC-7460 will be dispositioned to replace the existing Corner & Lada Size 7 sway strut assembly with an ITT Grinnell Sway Strut Assembly Size No. 7 as per design requirements. For the same size designation, the Corner & Lada sway strut has a ~ lower load capacity than the ITT Grinnell sway strut. To verify that other improper substitutions were not made, an evaluation will be made of other Corner & Lada sway strut installations. III. PROJECTED COMPLETION OF CORRECTIVE ACTION AND SUBMITTAL OF THE FINAL REPORT Evaluation of this condition and submittal of the Final Report is forecast to be completed by April 9,1984. t 'i gem'}}
