t Several certificates of conformance were chosen from various contracts at ' random for examination and were found te properly identify the purchased
items, identifying specific requirements the items met or did not meet, and i were signed by an appropriate member of the supplier's QA group where
applicable.
' The inspector examined the st ragt facilities of warehouse "A" (Levels A and B), warehouse "B" (Level C), the paint building (Level A) and various field i laydown areas (Level D). Random items and matet ials selected in these areas ] were found stored in their proper environment as described in the appro-priate Receiving, Inspection, Storage and Preventive Maintenance Manual
Instruction or by the manufacturer's recommendation. The subject storage ~ facilities were examined for proper controlled access, that protection from damage during storage was adequate, cleanliness, proper stacking and cribbing of items, proper control of items in storage to conclude identifi-cation and marking, proper use of desiccant humidity indicators and purging systems for required equipment, that shelf lih. of materials were adequately controlled, and that records were being maintained of storage conditions and were currant.
The inspector examined the " Warehouse Storage Area Inspection Reports" performed by QC for the period January 1980 through May 1981. The inspector also examined QA audits (6a(16) through 6a(22)) conducted in the areas of receiving inspection, storage and maintenance. These reports reflect that receiving, storage and maintenance conditions were being met and that any discrepancies noted received proper, timely carrective action.
The inspector examined the preventive maintenance inspection documentation maintained in the document control vault for the f uel pool cooling water pump and motor (contract 84840-2, SN809202) and for Unit l's reactor coolant ECCS piping (contract 84840-2, S/C KNZY1).
