-> Site Tours .

At periodic intervals generalized tours of the facility were per-formed by the Resident Inspector. These tours covered essentially all areas of the site. The tours were intended to assess the cleanliness of the site; construction activities in progress; storage condition of equipment and piping used in site construction; and the potential for fire or other hazards which might have a ,

dilaterious affect on personnel and equipmen It was noted during these tours that temporary lay down areas for safety related piping were starting to deteriorate. This was brough to the licensee's attention and immediate steps were taken to upgrade the temporary '
