Interim Report - DER 85-4 A 50.55(e) Potentially Reportable Deficiency Relating To Type 'A' Fire Damper Installation File: 85-019-026; D.4.33.2
Reference:
Telephone Conversation between L. Miller and T. Bradish on February 11, 1985
Dear Sir:
The NRC was notified of a potentially reportable deficiency in the ref-erenced 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 April 1, 1985, at which time a complete report will be submitted.
Very truly yours, Cu<b l /

INTERIM REPORT - DER 85-4 POTENTIAL REPORTABLE DEFICIENCY ARIZONA PUBLIC SERVICE COMPANY (APS)
PVNGS UNIT 2, 3 I.
Potential Problem Compliance of the Type "A" fire damper installation with the UL requiremetns is indeterminate due to conflict between the installa-tion instructions provided by the manufacturer (Ruskin) and the installation procedures used by the subcontractor (Waldinger Corporation).
Ruskin installation instructions require 1-inch welds on 6-to 8-inch centers on both sides of the dampers; Waldinger installed the dampers with the 1/2-inch weld on 12-inch centers on one side only.
II.
Approach To and Status Of Proposed Resolution Bechtel Engineering is currently studying this problem to determine reportability and technical justification for corrective action.
III. Projected Completion of Corrective Action and Submittal of the Final Report The complete evaluation and final report are forecast to be
~
completed by April 1, 1985.
