Two beam path direction cbverage is normally obtained using one half V-path shear waves from both sides of the weld or alternatively, full V-path shear waves from one side of the weld. However, the weld joint geometry, which is essentially a branch connection arrangement using a set-on nozzle, prevented scanning fromboth sides of the weld in two beam path directions and a full V-path examination from one side is prevented because of the stainless steel weld metal properties which cause excessive attenuation with shear waves. Substituting refracted longitudinal waves-for shear waves is not possible because of themodeconversion occurring at.the inside surface when using refracted longitudinal waves. In order to scan all of the required volume for this weld, the inlet nozzle would have to be redesigned to allow scanning from both sides of the weld, which is impractical.

Impracticality of Compliance The valve material is SA-35 1/CF8M cast stainless steel and the pipe material is SA 376/TP304 or TP316 stainless steel. This weld has a diameter of 10.0 inches and a wall thickness of 1.125 inches.During the ultrasonic examination of this weld, 50% coverage of the required examination volume was obtained.
The ID's and Item Numbers/Summary Numbers for the seven welds are as follows:
The percentage of coverage represents the aggregate coverage from all scans performed on the weld and adjacent base material.
List Number           Weld ID             Item Number/Summary Number
The coverage from each scan was as follows: 450 shear wave circumferential scans, both clockwise and counter-clockwise, covered 80% of the weld and base material; 600 shear wave scan from the pipe side perpendicular to the weld covered 40% of the weld and base material.
: 1.             2-LDCA-IN-V1               B03.150.001
A supplemental scan using a 60' refracted longitudinal wave search unit covered 50% of the examination volume on the valve side from one direction perpendicular to the weld, but is not included in the coverage calculations because the requirements of 1OCFR50.55 a (b)(2)(xv)(A)(l) mandate scanning from four directions.
: 2.             2-LDCA-OUT-V2             B03.150.002
The limitation was caused by the taper on the valve side of the weld (which prevented scanning from that side) and the proximity of a 1 1/22" branch connection.
: 3.             2LP-148-16                 C05.011.001
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:

There were no recordable indications found during the inspection of this weld.V. Proposed Alternate Examinations or Testing 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.

Relief Request 08-ON-001 Page 7 of 20 VI. Implementation Schedule and Duration This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on September 9, 2014.VII. Justification for Granting Relief Ultrasonic examination of the weld for item number C05.01 1 Was conducted using personnel, equipment and procedures qualified in liccordance with ASME Section XI, Appendix VIII, Supplement 2 of the 1998 Edition with the 2000 Addenda as administered by the PDI. In addition to the volumetric examination with limited coverage, Duke performed a Liquid Penetrant (PT) examination (code required) on the C05.011 item and achieved 100% coverage.
: 6.             2HP-227-7                 C05.021.028
The result from the PT examination was acceptable.
: 7.             2-51A-28-67               C05.021.073 Attachment A contains the inspection data for these seven welds.
In addition to the C05.01 I weld of this relief request, there were two other C05.01 I welds that surface (PT) and volumetric examinations were performed on during the outage. The examinations didn't identify any recordable indications and 100% coverage was obtained on each of them. The two additional welds were from the same system as the C05.011 weld of this request. The examination and results of the two additional welds contributes to the reasonable assurance of pressure boundary integrity for this system piping.Duke does not claim credit for coverage of the far side of austenitic welds. The characteristics of austenitic weld metal attenuate and distort the sound beam when shear waves pass through the weld. Refracted longitudinal waves provide better penetration but cannot be used beyond the first path leg. Duke uses a combination of shear waves and longitudinal waves to examine single sided austenitic welds when the nominal material thickness exceeds 0.5 inch. A 60' refracted longitudinal wave is used to interrogate the far side of the weld when the nominal material thickness is greater than 0.5 inch.Duke will use Class 2, Examination Category C-H, pressure testing and VT-2 visual examination to compliment the limited examination coverage.
Items in this relief request were examined during August or November of 2005
The Code requires that a pressure test be performed once each period for Class 2 items. These tests require a VT-2 visual examination for evidence of leakage. This testing contributes to the reasonable assurance of pressure boundary integrity.

During the ultrasonic examination of the Inlet Nozzle to Channel Head weld, 29.26%
coverage of the, required examination volume was obtained. The percentage of coverage
    !eported represents the aggregate coverage from all scans performed on the weld and adjacent base material. ASME Section XI, Appendix i11, ,11-4420 requires coverage of.the examination volume in two beam path directions aTnd Appendix III, 111-4430 requires scanning on the weld crown in two directions. Because of the weld configuration, these*
requirements could not be met. The coverage from each scan was as follows: 450 scan parallel to the weld covered 28.57%; 60' scan perpendicular to the' weld covered 29.95%.
Limited scanning was performed on the weld crown. Two beam path direction cbverage is normally obtained using one half V-path shear waves from both sides of the weld or alternatively, full V-path shear waves from one side of the weld. However, the weld joint geometry, which is essentially a branch connection arrangement using a set-on nozzle, prevented scanning fromboth sides of the weld in two beam path directions and a full V-path examination from one side is prevented because of the stainless steel weld metal properties which cause excessive attenuation with shear waves. Substituting refracted longitudinal waves-for shear waves is not possible because of themodeconversion occurring at.the inside surface when using refracted longitudinal waves. In order to scan all of the required volume for this weld, the inlet 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.

VII. Justification for Granting Relief Ultrasonic examination of the weld, for item number B03. 150 was conducted using personnel, qualified in accordance with ASME Section XI, Appendix VII of the 1998 Edition with the 2000 Addenda. The ultrasonic procedures used complied with the requirements of ASME Section XI, Appendix 111, 1998 Edition through the 2000 Addenda.
Duke will use Class 1, Examination Category B-P, pressure testing and VT-2 visual examination to compliment the limited scan examination. The Code requires that a pressure test be performed after each refueling outage for Class 1. This test requires a VT-2 visual examination for evidence of leakage. This testing contributes to the reasonable 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, operations performs a leakage calculation daily to assure system leak rate limitations imposed by Technical Specifications 3.4.13, "Reactor Coolant System Leakage," are not exceeded and reactor building normal sump rate monitoring to provide additional assurance that any leakage would be detected prior to gross failure of the component.
Duke has examined the weld/component to the maximum extent possible. The weld/component was rigorously inspected by volumetric NDE methods during construction and verified to be free from unacceptable fabrication defects. Based on the coverage an d results of the required volumetric exam, and the pressure testing (VT-2) exam during this outage, it, is Duke's position that this combination of examinations provides a reasonable assurance of quality and safety.

Impracticality of Compliance The valve material is SA-35 1/CF8M cast stainless steel and the pipe material is SA 376/TP304 or TP316 stainless steel. This weld has a diameter of 10.0 inches and a wall thickness of 1.125 inches.
During the ultrasonic examination of this weld, 50% 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 80% of the weld and base material; 600 shear wave scan from the pipe side perpendicular to the weld covered 40% of the weld and base material. A supplemental scan using a 60' refracted longitudinal wave search unit covered 50% of the examination volume on the valve side from one direction perpendicular to the weld, but is not included in the coverage calculations because the requirements of 10CFR50.55 a (b)(2)(xv)(A)(l) mandate scanning from four directions. The limitation was caused by the taper on the valve side of the weld (which prevented scanning from that side) and the proximity of a 1 1/22" branch connection. 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: There were no recordable indications found during the inspection of this weld.
V. Proposed Alternate Examinations or Testing 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.

VII. Justification for Granting Relief Ultrasonic examination of the weld for item number C05.01 1 Was conducted using personnel, equipment and procedures qualified in liccordance with ASME Section XI, Appendix VIII, Supplement 2 of the 1998 Edition with the 2000 Addenda as administered by the PDI. In addition to the volumetric examination with limited coverage, Duke performed a Liquid Penetrant (PT) examination (code required) on the C05.011 item and achieved 100% coverage. The result from the PT examination was acceptable.
In addition to the C05.01 I weld of this relief request, there were two other C05.01 I welds that surface (PT) and volumetric examinations were performed on during the outage. The examinations didn't identify any recordable indications and 100% coverage was obtained on each of them. The two additional welds were from the same system as the C05.011 weld of this request. The examination and results of the two additional welds contributes to the reasonable assurance of pressure boundary integrity for this system piping.
Duke does not claim credit for coverage of the far side of austenitic welds. The characteristics of austenitic weld metal attenuate and distort the sound beam when shear waves pass through the weld. Refracted longitudinal waves provide better penetration but cannot be used beyond the first path leg. Duke uses a combination of shear waves and longitudinal waves to examine single sided austenitic welds when the nominal material thickness exceeds 0.5 inch. A 60' refracted longitudinal wave is used to interrogate the far side of the weld when the nominal material thickness is greater than 0.5 inch.
Duke will use Class 2, Examination Category C-H, pressure testing and VT-2 visual examination to compliment the limited examination coverage. The Code requires that a pressure test be performed once each period for Class 2 items. These tests require a VT-2 visual examination for evidence of leakage. This testing contributes to the reasonable assurance of pressure boundary integrity.
In addition to the above Code required examinations (volumetric, surface 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, reactor building normal sump rate monitoring provides additional assurance that any leakage would be detected prior to gross failure of the component.

Duke DA ViceVEPresident BAXTER PoEnergyo Oconee Nuclear Station Duke Energy Corporation ON01 VP17800 Rochester Highway Seneca, SC 29672 864-885-4460 864-885-4208 fax April 29, 2008 dabaxter@dukeenergy.com U.S. Nuclear Regulatory Commission Attn: Document Control Desk Washington, DC 20555-0001

Subject:

Duke Energy Carolinas, LLC Oconee Nuclear Station, Unit 2 Docket No: 50-270 Fourth Ten Year Inservice Inspection Interval Request for Relief No. 08-ON-001 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 08-ON-001 is to allow Duke Energy to take credit for seven (7) limited ultrasonic examinations on welds associated with various systems and components described in the attached request. The ultrasonic'examination coverage of the subject Unit 2 welds did not meet the 90% examination requirements of Code Case N-460. The obtainable volume coverage for weld examination is indicated on the attached requests. Achievement of greater examination coverage for these welds is impractical due to piping/valve geometry and interferences. 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, DEave B 7ter,.

1. ASME Code Component Affected Weld ID = 2-LDCA-IN-VI Item Number B03.150.001 High Pressure Injection System Letdown Cooler 2A Inlet Nozzle to Channel Body Weld II. Applicable Code Edition and Addenda ASME Section XI Code - 1998 Edition thru the 2000 Addenda III. Applicable Code Requirement Table IWB-2500-1, Examination Category B-D Item Number B3.150 Appendix III, 111-4420 and 111-4430 Fig. IWB-2500-7(c), 100% Volume Coverage of Examination Volume A-B-C-D-E-F-G-H IV. Impracticality of Compliance The Letdown Cooler Inlet Nozzle and Channel Head material is SA 182 Grade T3 I 6L.

This weld has a diameter of 3.0 inches and a wall thickness of .875 inches.

During the ultrasonic examination of the Inlet Nozzle to Channel Head weld, 29.26%

coverage of the, required examination volume was obtained. The percentage of coverage

!eported represents the aggregate coverage from all scans performed on the weld and adjacent base material. ASME Section XI, Appendix i11, ,11-4420 requires coverage of.the examination volume in two beam path directions aTnd Appendix III, 111-4430 requires scanning on the weld crown in two directions. Because of the weld configuration, these*

requirements could not be met. The coverage from each scan was as follows: 450 scan parallel to the weld covered 28.57%; 60' scan perpendicular to the' weld covered 29.95%.

Limited scanning was performed on the weld crown. Two beam path direction cbverage is normally obtained using one half V-path shear waves from both sides of the weld or alternatively, full V-path shear waves from one side of the weld. However, the weld joint geometry, which is essentially a branch connection arrangement using a set-on nozzle, prevented scanning fromboth sides of the weld in two beam path directions and a full V-path examination from one side is prevented because of the stainless steel weld metal properties which cause excessive attenuation with shear waves. Substituting refracted longitudinal waves-for shear waves is not possible because of themodeconversion occurring at.the inside surface when using refracted longitudinal waves. In order to scan all of the required volume for this weld, the inlet 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.

Relief Request 08-ON-001 Page 3 of 20 V. Proposed Alternate Examinations or Testing 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.

VI. Implementation Schedule and Duration This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on September 9, 2014.

VII. Justification for Granting Relief Ultrasonic examination of the weld, for item number B03. 150 was conducted using personnel, qualified in accordance with ASME Section XI, Appendix VII of the 1998 Edition with the 2000 Addenda. The ultrasonic procedures used complied with the requirements of ASME Section XI, Appendix 111, 1998 Edition through the 2000 Addenda.

Duke will use Class 1, Examination Category B-P, pressure testing and VT-2 visual examination to compliment the limited scan examination. The Code requires that a pressure test be performed after each refueling outage for Class 1. This test requires a VT-2 visual examination for evidence of leakage. This testing contributes to the reasonable 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, operations performs a leakage calculation daily to assure system leak rate limitations imposed by Technical Specifications 3.4.13, "Reactor Coolant System Leakage," are not exceeded and reactor building normal sump rate monitoring to provide additional assurance that any leakage would be detected prior to gross failure of the component.

Duke has examined the weld/component to the maximum extent possible. The weld/component was rigorously inspected by volumetric NDE methods during construction and verified to be free from unacceptable fabrication defects. Based on the coverage an d results of the required volumetric exam, and the pressure testing (VT-2) exam during this outage, it, is Duke's position that this combination of examinations provides a reasonable assurance of quality and safety.

Impracticality of Compliance The Letdown Cooler Outlet Nozzle and Channel Head material is SA 182 Grade T3 16L.

This weld has a diameter of 3.0 inches and a wall thickness of -875 inches.

During the ultrasonic examination of the Outlet Nozzle to Channel Head weld, 29.26.%

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. ASME Section XI, Appendix III, I11-4420 reCLuires coverage of the examination volume in two beam path directions and Appendix 111, 111-4430 requires scanning on the weld crown in two directions. Because of the weld configuration, these requirements could not be met. The coverage from each scan was as follows: 450 scan parallel to the wel]d covered 28.57%; 600 scan perpendicular to the weld covered 29.95%.

Two beam path direction coverage is normally obtained using one half V-path shear waves from both sides of the weld or alternatively, full V-path shear waves from one side of the weld. However, the weld joint geometry, which is essentially a branch connection arrangement using a set-on nozzle, prevented scanning from both sides of the weld in two beam path directions and a full V-path examination from one side is prevented because of the stainless steel weld metal properties which cause excessive attenuation with shear waves. Substituting refracted longitudinal waves for shear waves is not possible because of the mode conversion occurring at the inside surface when using refracted longitudinal waves. In order to scan all of the required volume for this weld, the outlet 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.

VI. Implementation Schedule and Duration This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on September 9, 2014.

VII. Justification for Granting Relief I

Ultrasonic examination of the weld for item number B03.150 was conducted using personnel, qualified in accordance with ASME Section XI, Appendix VII of the 1998 Edition with the 2000 Addenda. The ultrasonic procedures used complied with the requirements of ASME Section XI, Appendix 1ll, 1998 Edition through the 2000 Addenda.

'Duke will use Class 1, Examination Category B-P, pressure testing and VT-2 visual examination to compliment the limited scan examination. The Code requires that a pressure test be performed after each refueling outage for Class 1. This test requires a VT-2 visual examination for evidence of leakage. This testing contributes to the reasonable 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.

Relief Request 08-ON-001 Page 6 of 20 I. ASME Code Component Affected Weld ID = 2LP-148-16 Item Number = C05.01 1.001 Low Pressure Injection System Pipe to Valve 2LP-47 Weld II. Applicable Code Edition and Addenda ASME Section XI Code - 1998 Edition thru the 2000 Addenda III. Applicable Code Requirement Table IWC-2500- 1, Examination Category C-F-I Item Number C5.11 Fig. IWC-2500-7(a), 100% Volume Coverage of Examination Volume C-D-E-F IV. Impracticality of Compliance The valve material is SA-35 1/CF8M cast stainless steel and the pipe material is SA 376/TP304 or TP316 stainless steel. This weld has a diameter of 10.0 inches and a wall thickness of 1.125 inches.

During the ultrasonic examination of this weld, 50% 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 80% of the weld and base material; 600 shear wave scan from the pipe side perpendicular to the weld covered 40% of the weld and base material. A supplemental scan using a 60' refracted longitudinal wave search unit covered 50% of the examination volume on the valve side from one direction perpendicular to the weld, but is not included in the coverage calculations because the requirements of 10CFR50.55 a (b)(2)(xv)(A)(l) mandate scanning from four directions. The limitation was caused by the taper on the valve side of the weld (which prevented scanning from that side) and the proximity of a 1 1/22" branch connection. 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: There were no recordable indications found during the inspection of this weld.

V. Proposed Alternate Examinations or Testing 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.

Relief Request 08-ON-001 Page 7 of 20 VI. Implementation Schedule and Duration This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on September 9, 2014.

VII. Justification for Granting Relief Ultrasonic examination of the weld for item number C05.01 1 Was conducted using personnel, equipment and procedures qualified in liccordance with ASME Section XI, Appendix VIII, Supplement 2 of the 1998 Edition with the 2000 Addenda as administered by the PDI. In addition to the volumetric examination with limited coverage, Duke performed a Liquid Penetrant (PT) examination (code required) on the C05.011 item and achieved 100% coverage. The result from the PT examination was acceptable.

In addition to the C05.01 I weld of this relief request, there were two other C05.01 I welds that surface (PT) and volumetric examinations were performed on during the outage. The examinations didn't identify any recordable indications and 100% coverage was obtained on each of them. The two additional welds were from the same system as the C05.011 weld of this request. The examination and results of the two additional welds contributes to the reasonable assurance of pressure boundary integrity for this system piping.

Duke does not claim credit for coverage of the far side of austenitic welds. The characteristics of austenitic weld metal attenuate and distort the sound beam when shear waves pass through the weld. Refracted longitudinal waves provide better penetration but cannot be used beyond the first path leg. Duke uses a combination of shear waves and longitudinal waves to examine single sided austenitic welds when the nominal material thickness exceeds 0.5 inch. A 60' refracted longitudinal wave is used to interrogate the far side of the weld when the nominal material thickness is greater than 0.5 inch.

Duke will use Class 2, Examination Category C-H, pressure testing and VT-2 visual examination to compliment the limited examination coverage. The Code requires that a pressure test be performed once each period for Class 2 items. These tests require a VT-2 visual examination for evidence of leakage. This testing contributes to the reasonable assurance of pressure boundary integrity.

In addition to the above Code required examinations (volumetric, surface 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, reactor building normal sump rate monitoring provides additional assurance that any leakage would be detected prior to gross failure of the component.

Relief Request 08-ON-001 Page 8 of 20 Duke has examined the weld/component to the maximum extent possible utilizing the latest approved examination techniques and equipment. The weld/component 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 required volumetric and surface examinations performed during this outage, and the pressure testing (VT-2) examinations required by Section XI, it is Duke's position that this combination of examinations provides a reasonable assurance of quality and safety.

This weld has a diameter of 4.0 inches and a wall thickness of .531 inches; During the'ultrasonic examination of this weld, 37.50% 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; 600 shear wave scan perpendicular to the weld ýovered 50% of the weld and base material from one axial direction. A supplemental scan using a 600 refracted longitudinal wave search unit Covered 50% of the exam volume from one direction perpendicular to the weld but is not included in the coverage calculations because the requirements of 10CFR50.55 a (b)(2)(xv)(A)(1) mandate scanning from four directions.

In addition to the volumetric examination with limited coverage, Duke performed a Liquid Penetrant (PT) examination (code required) on this C05.021 item and achieved 100% coverage. The result from the PT examination was acceptable.

In addition to the four C05.021 welds of this relief request, there were twelve additional C05.021 welds that surface (PT) and volumetric examinations were performed on during the outage. Eleven of the welds that were examined didn't identify any recordable indications and 100% coverage was obtained on each of them. One of the welds examined identified recordable indications (porosity & tungsten) during the volumetric examination that were acceptable per the 1998 Edition thru the 2000 Addenda of the Section XI Code, Paragraph IWB-3514.3, Table IWB-3514-2. 100% coverage was obtained on the weld that had recordable indications.

Proposed Alternate Examinations or Testing 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.

Relief Request 08-ON-001 Page 16 of 20 VI. Implementation Schedule and Duration This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on September 9, 2014.

VII. Justification for Granting Relief Ultrasonic examination of the weld for item number C05.021 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 PDI. In addition to the volumetric examination with limited coverage, Duke performed a Liquid Penetrant (PT) examination (code required) on this C05.021 item and achieved 100% coverage. The result from the PT examination was acceptable.

In addition to the four C05.021 welds of this relief request, there were twelve additional C05.021 welds that surface (PT) and volumetric examinations were performed on during the outage. Eleven of the welds that were examined didn't identify any recordable indications and 100% coverage was obtained on each of them. One of the welds examined identified recordable indications (porosity & tungsten) during the volumetric examination that were acceptable per the 1998 Edition thru the 2000 Addenda of the Section XI Code, Paragraph 1WB-3514.3, Table IWB-3514-2. 100% coverage was obtained on the weld that had recordable indications. The twelve additional welds were from the same system as the C05.021 weld of this request. The examination and results of the twelve additional welds contributes to the reasonable assurance of pressure boundary integrity for this system piping.

Duke does not claim credit for coverage of the far side of austenitic welds. The characteristics of austenitic weld metal attenuate and distort the sound beam when shear waves pass through the weld. Refracted longitudinal waves provide better penetration but cannot be used beyond the first path leg. Duke uses a combination of shear waves and longitudinal waves to examine single sided austenitic welds when the nominal material thickness exceeds 0.5 inch. A 600 refracted longitudinal wave is used to interrogate the far side of the weld when the nominal material thickness is greater than 0.5 inch.

Duke will use Class 2, Examination Category C-H, pressure testing and VT-2 Visual examination to compliment the limited examination coverage. The Code requires that a pressure test be performed once each period for Class 2 items. These tests require a VT-2 visual examination for evidence of leakage. This testing contributes to the reasonable assurance of pressure boundary integrity.

Relief Request 08-ON-001 Page 17 of 20 In addition to the above Code required examinations (volumetric, surface, 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, operations performs a leakage calculation daily to assure system leak rate limitations imposed by Technical Specifications 3.4.13, "Reactor Coolant System Leakage," are not exceeded and visual observations during operator rounds to provide additional assurance that any leakage would be detected prior to gross failure of the component.

Duke has examined the weld/component to the maximum extent possible utilizing the latest approved examination techniques and equipment. The weld/component 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 required volumetric and surface examinations performed during this outage, and the pressure testing (VT-2) examinations required by Section XI, it is Duke's position that this combination of examinations provides a reasonable assurance of quality and safety.

1. ASME Code Component Affected Weld ID = 2-5 [A-28-67 Item Number = C05.021.073 High Pressure Injection System Tee to Pipe Weld II. Applicable Code Edition and Addenda ASME Section XI Code - 1998 Edition thru the 2000 Addenda III. Applicable Code Requirement Table IWC-2500- 1, Examination Category C-F-I Item Number C5.21 Fig. IWC-2500-7(a), 100% Volume Coverage of Examination Volume C-D-E-F IV. Impracticality of Compliance The tee material is SA 403/WP304 or WP316 stainless steel and the pipe material is SA 376/TP 304 or TP316 stainless steel seamless pipe. This weld has a diameter of 2.5 inches and a wall thickness of .375 inches.

During the ultrasonic examination of this weld, 79.15% coverage of the required examination volume was obtained. The percentage of coverage represents the aggregate coverage with 450 and 600 shear wave 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; 600 shear wave scan perpendicular to the weld covered 72.2% of the weld and base material from two axial directions, (100% from the pipe side and 44% from the tee side at the 900 and 2700 quadrants). A supplemental scan using a 700 shear scan search unit covered 55.6% of the weld and adjacent base material from one direction perpendicular to the weld including 100% of the inside surface within the area of interest.

The limitation was caused by configuration of the tee which prevented scanning from that side in the 00 and 1800 quadrants. In order to scan all of the required volume for this weld, the tee would have to be redesigned to allow scanning from both sides of the weld around the full circumference, which is impractical. There were no recordable indications found during the inspection of this weld.

V. Proposed Alternate Examinations or Testing 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.

Duke does not claim credit for coverage of the far side of austenitic welds. The characteristics of austenitic weld metal attenuate and distort the sound beam when shear waves pass through the weld. However, the shear wave is useable when the sound beam passes through the root of the weld at a high angle such as 700. Duke uses a 70' shear wave angle beam to interrogate the far side of the weld when the nominal material thickness is equal to or less than 0.5 inch.

Duke will use Class 2, Examination Category C-H, pressure testing and VT-2 visual examination to compliment the limited examination coverage. The Code requires that a pressure test be performed once each period for Class 2 items. These tests require a VT-2 visual examination for evidence of leakage.
