l WELDED CONDUIT SUPPORTS l

.

'

s, Description of Deficiency Monitoring efforts by QA personnel indicated the following two discrepancies in the area of Site-fabricated, welded conduit supports:

i

1) A major support was being fabricated without fccmalized instructions, procedures or drawings and thus appropriate

control of construction activities could not be directly

] verified.

2) Inspection records for a number of smaller welded supports were not directly traceable to the "as built" conditions and it was not porsible to directly verify control of the welding process.

'

Evaluation of the results of both of these ccnditions is currently under-way by our CPSES Site QA Staff. At the present time, we have not yet determined the safety consequences, if any, of the noted discrepancies.

Corrective Actions j Corrective actions for the above stated discrepancies have included the following: '

1) Typical engineering drawings for the major support has been

• developed and has been included in the corduit support package (2323-5-910) for CPSES. This act, ton was completed

!

on January 24, 1980. Contingency plans ~ provide for the use

,

of formalized instructions such as the " Construction Opera-tion Traveler" in the event that details other than those

..

included on the typical engineering drawings are required to formally control construction activities.

)

2) The formal inspection instruction QI-QP-11.10-1 entitled

" Inspection of Exposed Conduit Raceway Support Systems" was revised on December 11, 1979 and corrects the record trace-ability discrepancy. In addition, control of the welding process is maintained and documented on the Site inspection documents.
