Y FINAL REPORT - DER 82-28 DEFICIENCY EVALUATION 50.55(e)

ARIZONA PUBLIC SERVICE COMPANY (APS)

PVNCS UNITS 1, 2 & 3

1. DESCRIPTION OF DEFICIENCY While performing verification of fan blade pitch in accordance with the Joy Manufacturing instruction manual. The Waldinger Corporation (the Project's HVAC Subcontractor) found various fan blade attaching bolts to be under the torque specified by the manufacturer. An additional sample by Bechtel Construction found that there was one (1) of twelve (12) bolts under-torqued (85 f t/lbs. versus 130 f t/lbs.) on the Fuel Building Exhaust Essential Fan.

II. ANALYSIS OF SAFETY IMPLICATIONS This condition is evaluated as not reportable based on data provided by Joy Manufacturing Company, who advised Bechtel Engineering and The Waldinger Corporation that checking the blade torque values was not required and would produce no meaningful results. (See attached Telex, Joy Manufacturing Company to William Bingham).

III. CORRECTIVE ACTION Nonconformance Report MY-1286 will be dispositioned as use-as-is.
