INTERIM REPORT - DER 84-25 POTENTIAL REPORTABLE DEFICIENCY ARIZONA PUBLIC SERVICE COMPANY (APS)
PVNGS UNITS 1, 2, & 3 I. Potential Problem During receiving inspection, Containment Supply Registers would not cycle. The tension wire (music wire) that is used for blade adjustments have become brittle and break off.
The same type supply registers have been installed into Units 1, 2 and 3.
It has been identified that similar problems were observed in the installed units.
In the event of a shutdown, no air would be able to travel through those devices if the wire was broken.
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 Compeltion 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 August 17, 1984.
