s INTERIM REPORT - DER 82-57 POTENTIAL REPORTABLE DEFICIENCY ARIZONA PUBLIC SERVICE COMPANY (APS)
PVNGS UNITS 1, 2 & 3 I.
POTENTIAL PROBLEM As discovered by the Torrey Pines Technology Independent QA Evaluation, drawings 13-P-ZZG-012 and 13P-ZZG-013 require 3" through 8" globe valves identified by mark #350 be constructed of SA351 GR CF 8M or SA182 GR F316 (stainless steel material).
Contrary to the above drawings, valves AFB-HB-30, AFB-HV-31, AFA-HV-32 and AFC-HV-33 were supplied with a body made of SA105 and SA106 carbon steel material as per motor actuated valve data sheet 13-J-081-060, Revision 1.
These valves are installed at the auxiliary feedwater discharge lines to throttle demineralized water flow to the steam generators during an Auxiliary Feedwater Actuation Signal (AFAS) occurrence.
The cause of this problem is attributed to an oversight whereby the valve data sheet prepared and issued by project engineering for construction contained the incorrect material requirement.
II.
APPROACH TO AND STATUS OF PROPOSED RESOLUTION Bechtel's Material and Quality Services Department (M&QS) will evaluate the servicability of carbon steel valves in this situation, or the need for replacement. The other valve data sheets will be reviewed to ensure that all valves are correctly specified.
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 December 28, 1982.
