Subject:

Duke Power Company LLC d/b/a Duke Energy Carolinas, LLC (Duke)

Oconee Nuclear Station, Unit 1 Docket Nos. 50-269 Fourth Ten Year Inservice Inspection Interval Request for Relief No. 07-ON-002 Pursuant to 10 CFR 50.55a(g)(5)(iii), attached is a Request for Relief from the requirement to examine 100% of the volume specified by the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code),

Section XI, Rules for Inservice Inspection of Nuclear Power Plant Components, 1998 Edition with 2000 Addenda (as modified by Code Case N-460).

Request for Relief 07-ON-002 is to allow Duke Energy to take credit for sixteen (16) limited ultrasonic examinations on welds associated with various systems and components described in the attached request. The ultrasonic examination coverage of the subject Unit 1 welds did not meet the 90% examination requirements of Code Case N-460. The obtainable volume coverage for each weld examination is indicated on the attached requests. Achievement of greater examination coverage for these welds is impractical due to piping/valve geometry, interferences, and existing examination technology. Therefore, Duke Energy requests that the NRC grant relief as authorized under 10 CFR 50.55a(g)(6)(i).

If there are any questions or further information is needed you may contact Corey Gray at (864) 886-6325.

Very truly yours, Dave B xter Site Vice President Enclosure www. duke-energy.com

Applicable Code Requirement IWB-2500, Table IWB-2500-1, Examination Category B-D, Item Number B3.1 10 Fig. IWB-2500-7 (a), 100% Volume Coverage of Examination Volume A-B-C-D-E-F-G-H-I IV. Impracticality of Compliance The pressurizer lower head material is SA-212 Gr. B carbon steel and the surge nozzle material is SA-508 CL. 1 carbon steel. This weld has a diameter of 15.250 inches and a wall thickness of 4.750 inches.

During the ultrasonic examination of this weld, 56.92% coverage of the required examination volume was obtained. The percentage of coverage reported represents the aggregate coverage from all scans performed on the weld and adjacent base material. The coverage from each scan was as follows: 450 and 600 shear wave scans perpendicular and parallel to the weld in one axial direction and two circumferential directions and 0' longitudinal wave scans covered 6 1.34 % of the base material from the head side. 45' and 600 shear wave scans perpendicular and parallel to the weld in one axial direction and two circumferential directions and 00 longitudinal wave scans covered 52.49% of the weld volume from the head side. In order to scan all of the required volume for this weld, the surge nozzle would have to be redesigned to allow scanning from both sides of the weld, which is impractical, There were no recordable indications found during the inspection of this weld.

The Oconee Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage of examination volume A-B-C-D-E-F-G-H-I.

Therefore, the available coverage will not meet the acceptance criteria of this Code Case.

V. Proposed Alternate Examinations or Tests Radiography as an alternative is not feasible because access is not available for film placement. No alternative examinations are planned for the weld during the current inspection interval.

VII. Justification for Grantinig Relief Ultrasonic examination of the weld for item number B03. 110.001 was conducted using personnel, qualified in accordance with ASME Section XI, Appendix VII of the 1998 Edition with the 2000 Addenda. Ultrasonic procedures complied with the requirements of ASME Section V, Article 4 of the 1998 Edition with the 2000 Addenda as amended by Section XI, Appendix I.

IWB-2500, Table IWB-2500- 1, Examination Category B-P System Leakage Tests and VT-2 visual examinations performed each refueling outage provide adequate assurance of pressure boundary integrity.

In addition to the above Code required examinations (volumetric and pressure test), there are other activities which provide a high level of confidence that, in the unlikely event that leakage did occur through this weld it would be detected and proper action taken.

Specifically, system leak rate limitations imposed by Technical Specifications 3.4.13, "Reactor Coolant System Leakage," as well as reactor building normal sump rate monitoring, provide additional assurance that any leakage would be detected prior to gross failure of the component.

The component weld was rigorously inspected by volumetric NDE methods during construction and verified to be free from unacceptable fabrication defects. Based on the coverage and results of the volumetric and the pressure testing VT-2 examinations performed, it is Duke's position that this combination of examinations provides a reasonable assurance of quality and safety.

1. ASME Code Component Affected Class I Piping Weld Low Pressure Injection System Pipe to Valve ICF- II Weld Weld ID = 1-53A-02-68L Item Number/Summary Number B09.011.015 II. Applicable Code Edition and Addenda ASME Section XI Code - 1998 Edition thru the 2000 Addenda III. Applicable Code Requirement RWB-2500, Table IWB-2500- 1, Examination Category B-A Item Number B9.1 I Fig. IWB-2500-8 (c), 100% Volume Coverage of Examination Volume C-D-E-F IV. Impracticality of Compliance The valve material is A35 I GR. CF8M cast stainless steel and the pipe material is SA 376/TP 304 or 3 16 stainless steel seamless pipe. This weld has a diameter of 14.00 inches and a wall thickness of 1.250 inches.

During the ultrasonic examination of this weld, 36.70% coverage of the required examination volume was obtained. The percentage of coverage represents the aggregate coverage from all scans performed on the weld and adjacent base material. The coverage from each scan was as follows: 450 shear wave circumferential scans, both clockwise and counter-clockwise covered 50% of the weld and base material; 45' and 60' shear wave scans perpendicular to the weld covered 46.6% of the weld and base material from one axial direction. A supplemental scan using a 600 refracted longitudinal wave search unit covered 100% of the valve side from one axial direction but was not included in the percent of coverage. The limitation was caused by the taper on the valve side of the weld and the cast stainless steel valve body material which prevented scanning from that side.

In order to scan all of the required volume for this weld, the valve would have to be replaced with forged stainless steel and would have to be redesigned to allow scanning from both sides of the weld, which is impractical. There were no recordable indications found during the inspection of this weld.

The Oconee Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage of examination volumeC-D-E-F. Therefore, the available coverage will not meet the acceptance criteria of this Code Case.

Proposed Alternate Examinations or Tests Radiography (RT) is not a desired option because RT is limited in the ability to detect expected degradation mechanisms such as thermal fatigue cracking and stress corrosion crack initiating at the pipe inside surface. Additionally, Radiography has not been qualified through performance demonstration.

VII. Justification for Granting Relief Ultrasonic examination of the weld for the item number B09.011.015 was conducted using personnel, equipment and procedures qualified in accordance with ASME Section XI, Appendix VIII Supplement. 2 of the 1998 Edition with the 2000 Addenda as administered by the Performance Demonstration Initiative (PDI). in the case of this piping weld NRC has imposed requirements for coverage of stainless steel piping welds in IOCFR50.55a (b) (2) (xvi) (A) (1). This requires scanning of the weld and adjacent base material from four orthogonal directions. If this requirement cannot be met then the NRC will not allow credit for coverage on the far side of the weld unless a demonstration test is passed with all flaws being on the far side of the weld. The demonstration requires detection, length sizing and through wall sizing of flaws with the sound beam passing through the austenitic weld metal. Performance demonstration qualifications for cast stainless steel (Appendix VIII, Supplement 9) is in course of preparation and current qualifications for piping do not address cast stainless steel components such as the valve body. Therefore credit for ultrasonic coverage is not claimed. Use of radiography (RT) to achieve more coverage has been evaluated and discarded because RT is less sensitive to service induced cracking and has not been subjected to the performance demonstration requirements in a manner similar to the ultrasonic method. While RT could in most cases provide more coverage the loss of sensitivity and lack of performance demonstration militates against its use.

In addition to the B09.011 weld that relief is being requested for limited volume coverage, there were 15 additional B09.01 I welds that surface and volumetric examinations were performed on. The examinations didn't identify any recordable indications and 100% coverage was obtained on each of them. Twelve of the fifteen additional welds were from the Reactor Coolant System and three of the additional welds were from the Low Pressure Injection System.

The limitation was caused by four equally spaced-pads for support legs that prevented scanning in these areas. In order to scan all of the required volume for this weld, the support legs would have to be removed to allow scanning from both sides of the weld, which is impractical. There were no recordable indications found during the inspection of this weld.

The limitation was caused by the flow restrictor geometry and cast stainless steel material which prevented scanning from that side. In order to scan all of the required volume for this weld, the flow restrictor would have to be replaced with forged stainless steel material and redesigned to allow scanning from both sides of the weld, which is impractical. There was one geometric recordable indication found during the inspection of this weld.

The Oconee Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage of examination volume C-D-E-F. Therefore, the available coverage will not meet the acceptance criteria of this Code Case.

Relief Request 07-ON-002 Page 33 of 40 V. Proposed Alternate Examinations or Tests No alternative examinations are planned for the weld during the current inspection interval. Radiography (RT) is not a desired option because RT is limited in the ability to detect expected degradation mechanisms such as thermal fatigue cracking and stress corrosion crack initiating at the pipe inside surface. Additionally, Radiography has not been qualified through performance demonstration.

VI. Implementation Schedule and Duration This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on July 15, 2013.

VII. Justification for Granting Relief Ultrasonic examination of the weld for the item number C05.011.077 was conducted using personnel, equipment and procedures qualified in accordance with ASME Section XI, Appendix VIII Supplement 2 of the 1998 Edition with the 2000 Addenda as administered by the Performance Demonstration Initiative (PDI). In the case of this piping weld NRC has imposed requirements for coverage of stainless steel piping welds in IOCFR50.55a (b) (2) (xvi) (A) (1). This requires scanning of the weld and adjacent base material from four orthogonal directions. If this requirement cannot be met then the NRC will not allow credit for coverage on the far side of the weld unless a demonstration test is passed with all flaws being on the far side of the weld. The demonstration requires detection, length sizing and through wall sizing of flaws with the sound beam passing through the austenitic weld metal. Performance demnonstration qualifications for cast stainless steel, (Appendix VIII, Supplement 9) is in course of preparation and current qualifications for piping do not address cast stainless steel components such as the flow restrictor. Therefore credit for ultrasonic coverage is not claimed. Use of radiography (RT) to achieve more coverage has been evaluated and discarded because RT is less sensitive to service induced cracking and has not been subjected to the performance demonstration requirements in a manner similar to the ultrasonic method. While RT could in most cases provide more coverage the loss of sensitivity and lack of performance demonstration militates against its use.

In addition to the volumetric examination with limited coverage, Duke performed a surface examination (code required) on this C05.011 item and achieved 100% coverage.

The result from the surface examination was acceptable.

In addition to the six C05.01 I welds of this relief request, there were seventeen additional C05.01 I welds that surface (PT) and volumetric examinations were performed on during the outage. The examinations didn't identify any reportable indications. 100% coverage was obtained on all the surface examinations, fifteen of the volumetric examinations obtained 100% coverage and 97.20% coverage was obtained on two of the volumetric examinations. Two of the seventeen additional welds were from the Low Pressure Service Water System and fifteen of the additional welds were from the Low Pressure Injection System.

Relief Request 07-ON-002 Page 34 of 40 IWC-2500, Table IWC-2500- 1, Examination Category C-H System Leakage Tests and VT-2 visual examinations performed once each period provide adequate assurance of pressure boundary integrity.

In addition to the above Code required examinations (volumetric, surface, and pressure test), there are othe.r activities which provide a high level of confidence that, in the unlikely event that leakage did occur through this weld it would be detected and proper action taken. Specifically, reactor building normal sump rate monitoring, provides additional assurance that any leakage would be detected prior to gross failure of the component.

The component weld was rigorously inspected by volumetric NDE methods during construction and verified to be free from unacceptable fabrication defects. Based on the coverage and results of the volumetric, surface, and the pressure testing VT-2 examinations performed, it is Duke's position that this combination of examinations provides a reasonable assurance of quality and safety.

This weld has a diameter of 6.0 inches and a wall thickness of .432 inches.

During the ultrasonic examination of this weld, 62.50% coverage of the required examination volume was obtained. The percentage of coverage represents the aggregate coverage fr-om all scans performed on the weld and adjacent base material. The coverage from each scan was as follows: 450 shear wave circumferential scans, both clockwise and counter-clockwise covered 100% of the weld and base material; 60' shear wave scan perpendicular to the weld from the pipe side covered 50% of the weld and base material fr'om one axial direction. A supplemental scan using a 700 shear wave from the pipe side covered 100% of the examination volume on the far side of the weld but is not included in the percent of coverage. The limitation was caused by the taper on the valve side of the weld which prevented scanning from that side. In order to scan all of the required volume for this weld, the valve would have to be redesigned to allow scanning from both sides of the weld, which is impractical.

Additionally, Radiography has not been qualified through performance demonstration.

The ultrasonic (UT) techniques, though limited in coverage by virtue of the requirements in IOCFR50.55a, have been qualified through performance demonstration and are considered superior to RT for this application. Although the PDI does not offer a single sided qualification for stainless steel piping, circumferential flaws on the far side of stainless steel welds were detected during the performance demonstration.
