Subject:
Interim Report - DER 82-56 A 50.55(e) Potentially Reportable Deficiency Relating To Condensate Storage Tank Design Was Scaled-Down Without New Calculations For Seismic Response File: 82-019-026 D.4.33.2
Reference:
Telephone Conversation between J. Eckhardt and G. Duckworth on October 15, 1982
Dear Sir:
The NRC was notified of a potentially reportable deficiency in the referenced telephone conversation. At that time, it was estimated that a determination of reportability would be made within thirty (30) days.
Due to the extensive investigation and evaluation required, an Interim Report is attached.
It is now expected that this information will be finalized by January 11, 1983, at which time a complete report will be submitted.
Very truly yours, buhu N^

INTERIM REPORT - DER 82-56 POTENTIAL REPORTABLE DEFICIENCY ARIZONA PUBLIC SERVICE COMPANY (APS)
PVNGS UNITS 1, 2 & 3 I.
POTENTIAL PROBLEM This report was initiated as a result of the Torrey Pines Technology Independent Evaluation of PVNGS which requested that the design of the Condensate Storage Tank (CST) be re-evaluated.
The CST is required to be designed to resist stresses resulting from operating and extreme environment / accident seismic forces. The analysis and design of the CST was based on the design of the Refueling Water Tank. Wall reinforcement was scaled down because of the decreased height and mass of the CST without performing separate calculations.
A preliminary engineering review has indicated that the scaling approach utilized may not be appropriate and a separate calculation to confirm the integrity of the CST is being performed.
II.
APPROACH TO AND STATUS OF PROPOSED RESOLUTION Bechtel Engineering is currently performing a detailed analysis of the CST design and will coordinate and disposition the results of this evaluation with Torrey Pines Technology.
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 January 11, 1983, i
