Pursuant to the requirements of Article IWA-6000 of the ASME Code, Section XI, enclosed for your review is the Owner's Data Report for Inservice Inspection (Form NIS-1) for the inservice inspection activities conducted at Plant Hatch Unit I during the fall 1991 maintenance / refueling outage. The Owner's Dr.ta Report is included as Enclosure 1.
Georgia Power Company (GPC) has performed several inspections not specifically required by ASME Code.Section XI, on selected Class 1, 2, and 3 components.             The results of the Code and augmented inspections performed at Unit I are summarized below and reported in the Owner's Data Report.
o Ultrasonic examinations of austenitic stainless steel piping welds in the primary coolant pressure boundary per Generic letter 88-01 and NUREG-0313, Revision 2.         Results are discussed in the Enclosure under
                             " Class 1 Examinations." A detailed report on flaw evaluations and weld overlay designs was submitted to the NRC via {{letter dated|date=January 21, 1992|text=letter dated January 21, 1992}}.
o Ultrasonic examinations of eight (8) welds                                        in the nonsafety-related portion of the reactor water cleanup (RWCU) piping were performed per commitments          to the NRC related to Generic Letter 88-01.                                         No reportable indications were detected, o Ultrasonic           thickness measurements                                  were  performed on selected components       in the extraction steam and condensate /feedwater system piping per GPC's ongoing erosion / corrosion program. A portion of these components were selected due to their similarity in design and operating conditions to components involved with the "Surry pipe break incident".
