The snubbers were checked for smoothness of shaft travel by j simulating normal operation by pulling and pushing the snubber shaft; the inspector also simulated unit activation by sudden

of Mechanical Shock Arrestors," Section This difference prompted PPP to issue PCN-#3 to IX-32 to include the process sheets that were an abbreviated version of the prucess sheets in the procedure. The inspector reviewed four other procedures in the pipe support area and compared the process sheets - in the various procedures, with the process sheets issued by the Hanger Group for use by the QC inspectors in the fiel The inspector did not find any differences in those four procedures. Pending review and evaluation of procedures that require process sheets for-QC signatures by the licensee and further NRC inspection, this matter was identified as Unresolved Items 50-424/86-10-02 and 50-425/86-05-02, " Control of Process Sheets Used for QC signa-tures."

Construction Progress (Unit 1)

The inspector conducted a general inspection of the control and Auxiliary Building to observe construction progress and activities, such as welding, coatings, material handling and control, housekeeping-and storage. During the inspection of Restraint V1-1302-031-H009, in the Control Building area A/2E, erected and QC inspected in September 1985, it was noted that the restraints structural steel and welds had approximately 1/16" of oxidation covering them. Also, that prefab -

ricated pipe support structures were found to be left in an area not considered to be a temporary storage area for such materials. By the end of this inspection, this inspector was unable to determine whether adequate measures were in place for the protection of materials and equipment and, if measures were in place, why they were not followe Pending review and evaluation-of procedures that cover this area by the licensee and further NRC inspection, this matter was identified as Unresolved Items 50-424/86-10-03 and 50-425/86-05-03, " Handling, Storage and Preservation of Materials for Pipe Supports."
