INTERIM REPORT POTENTIAL REPORTABLE DEFICIENCY ARIZONA PUBLIC SERVICE COMPANY (APS)

• - PVNGS UNITS f!1 AND 82 I. Potential Problem Bechtel's source inspector at Comsip, Incorporated, Customline Division, Linden, New Jersey, identified some groove welds on the Main Control Panels which were not full penetration welds.

'Further inspections have indicated the following potential conditions which may impact the seismic analysis as follows:

o Less than 100% penetration on various seam welds.

o Deviations from the specified welding require-ments for base angle brackets.

~ . Deviations from the specified welding require-ments at the end frame used for bolting panels together.

~ Deficiencies in the '1/4" fillet welds between the edges of 2" and 4" tubing to the panel skin.

The affected control panels are currently located at both the jobsite and Comsip's facility.

II. A roach To and Status'Of"Pro osed Resolution Comsip and Bechtel are undertaking a detailed analysis and review of each of these conditions. If any Control Panels delivered or at Comsip require repair, it will be accomplished

'ollowing established nonconformance and weld repair procedures.

The proposed disposition and 'technical justification for accepting the deviations has been submitted by Comsip and is currently being reviewed by Bechtel.

III. Pro'ected Com letion 'of Cor'rective 'Action 'and Submittal of Date of the Final Re ort The ComsiplBechtel analysis and review of these conditions is forecast to be completed by 'November 1, 1980.

The final report will be submitted by November 15, 1980.
