Subject:

Duke Energy Carolinas, LLC Oconee Nuclear Station Unit 1 Docket No. 50-269 Fourth Ten-Year Inservice Inspection Plan Request for Relief No. 12-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 Xl, Rules for Inservice Inspection of Nuclear Power Plant Components, 1998 Edition with 2000 Addenda (as modified by Code Case N-460).

The attached Request for Relief 127ON-001 is to allow Duke Energy to take credit for the enclosed Table 1 list of limited ultrasonic examinations on welds associated with various systems and components during Unit 1 EOC26 refueling outage. 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 weld examination is indicated on Attachment A of the relief request. 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 50.55(g)(6)(i).

This submittal document contains no regulatory commitments.

If there are any questions or further information is needed you may contact Corey Gray at (864)-873-6325.

Sincerely, T. Preston Gillespie Jr.,

Oconee Relief Request 12-ON-001 2.0 Weld #1-PZR-WP26-3 2.1. ASME Code Component(s) Affected Unit 1 Pressurizer Heater Belt Shell to Sampling Nozzle Weld #1-PZR-WP26-3, Summary Number 01 .B3.110.0011 and ASME Code Class 1.

2.2. Applicable Code Edition and Addenda ASME Boiler and Pressure Vessel Code,Section XI, 1998 Edition through the 2000 Addenda.

2.3. 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.

2.4. Impracticality of Compliance Component configuration:

• Surface 1: Shell - Carbon steel

• Surface 2: Sampling nozzle - Carbon steel

• Diameter: 5.750 in.

• Thickness: 6.187 in.

This component was scanned manually with conventional methods. Scanning requirements are described in ASME Section V, Article 4, T-441.1.2(a),T-441.1.3, T-441.1.4, T-441.1.5 and T-441.1.6. These requirements describe and are specific to scanning components in two axial and two circumferential directions.

This component was scanned to the extent possible to meet these requirements.

The aggregate coverage that was obtained is described and calculated from the following:

• Weld coverage using 450& 600 shear waves for axial scans (S1, S2), and 450 & 600 shear waves for circumferential scans (CW, CCW) obtained 15.4% coverage.

• Base material coverage using 450& 600 shear wave for axial scans (51) and 450& 600 shear waves for circumferential scans (CW, CCW) obtained 54.8% coverage.

• 00 scan coverage obtained 33.8% coverage.

• The aggregate coverage was calculated to be (15.4% + 54.8% + 33.8%)/3 = 34.7%.

The impracticality was caused by the weld taper configuration of the sampling nozzle to the shell that does not allow meaningful interrogation from Surface 2, the sampling nozzle side. In order to scan all of the required volume for this weld, the shell to sampling nozzle weld would have to be redesigned or replaced to allow scanning from both sides of the weld, which is impractical.

Page 3 of 55

Oconee Relief Request 12-ON-001 The Oconee Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage. The achieved coverage did not meet the acceptance criteria of this Code Case.

This relief request is specific to examination volume coverage limitations only. All other Code requirements were satisfied.

No indications were recorded during this examination. The reject box on the UT Calibration/Examination sheet is marked for internal tracking of the coverage limitation only.

2.5. Proposed Alternative and Basis for Use No substitution alternative for this weld is available which would provide better coverage. Radiography (RT) is not a desired option because RT is limited in the ability to detect service induced flaws. Use of other manual or automated UT techniques, whether conventional or phased array, were considered, but would not increase coverage due to the limitation created by the component configuration. The use of any other UT technique available would incur the same physical scanning limitations.

2.6. Duration of Proposed Alternative This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on July 15, 2014.

2.7. Justification for Granting Relief Ultrasonic examination of the weld for the item number 01 .B3.110.0011 was conducted using personnel, equipment, and procedures qualified in accordance with ASME Section XI, 1998 Edition with the 2000 Addenda.

The system leakage test performed each refueling outage in accordance with Table IWB-2500-1, Examination Category B-P requires a VT-2 visual examination to detect evidence of leakage. This test and VT-2 examination provides additional assurance of pressure boundary integrity.

In addition to the above Code required examinations (volumetric and pressure test), Reactor Building Normal Sump monitoring and other leakage detection systems provide additional assurance that, in the event that leakage did occur through this weld, it would be detected and proper action taken.

Duke Energy has examined the weld to the maximum extent possible utilizing approved examination techniques and equipment. Based on the acceptable results for the coverage completed by the volumetric examination, the pressure testing (VT-2) examinations required by Section XI, and the leakage monitoring, it is Duke Energy's position that the combination of examinations provides a reasonable assurance of quality and safety.

4.4. Impracticality of Compliance Component configuration:

• Surface 1: Cast Stainless Steel Nozzle

" Surface 2: Forged Stainless Steel Safe End

• NPS: 36.5 in.

• Thickness: 2.330 in.

This component was scanned manually with conventional methods. Scanning requirements are described in 10 CFR 50.55a(b)(2)(xv)(A)(1). These requirements describe and are specific to scanning components in two axial and two circumferential directions. This component was scanned to the extent possible to meet these requirements. The aggregate coverage that was obtained is described and calculated from the following:

• 600 shear waves obtained 0% coverage in one axial direction (S1 - nozzle)

• 600 shear waves obtained 50% coverage in one axial direction (S2 - safe end)

• 450 shear waves obtained 50% coverage in one circumferential direction (CW).

• 450 shear waves obtained 50% coverage in one circumferential direction (CCW).

• The aggregate coverage was calculated to be (0% + 50% + 50% + 50%)/4 = 37.5%.

In addition, best effort supplemental scanning was performed using 600 and 700 refracted longitudinal waves from the S2 pump casing side for interrogation of the upper 2/3 area within the cast material.

Page 9 of 55

Oconee Relief Request 12-ON-001 Best effort supplemental scanning was also performed using 600 refracted longitudinal waves for interrogation of the lower 1/3 nozzle far side of the weld from the S1 safe-end side, but is not qualified to be calculated into the above claimed coverage. The supplemental refracted longitudinal scan was only used for interrogation in the axial direction per procedural direction. Supplemental scanning is not performed in the circumferential direction.

The impracticality was caused by the nozzle taper configuration and cast stainless steel material which cannot be effectively interrogated by ultrasound.

There are currently no examination techniques that have been qualified for cast stainless steel through Appendix VIII for cast stainless steel. Therefore, coverage could not be obtained by scanning from the nozzle side. In order to scan all of the required volume for this weld, the nozzle would have to be redesigned and replaced, which is impractical.

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

This relief request is specific to examination volume coverage limitations only. All other Code requirements were satisfied.

No indications were recorded during this examination. The reject box on each UT Calibration/Examination sheet is marked for internal tracking of the coverage limitation only.

4.5 Proposed Alternative and Basis for Use This weld was examined using procedures, equipment and personnel qualified in accordance with ASME Section XI, Appendix VIII. Radiography (RT) is not a desired option because RT is limited in the ability to detect service induced flaws and has not been qualified through performance demonstration. Use of other manual or automated UT techniques, whether conventional or phased array, qualified under ASME Section XI, Appendix VIII would not increase coverage due to the limitation created by the cast stainless material. The use of any other UT technique available would incur the same physical scanning limitations.

4.6. Duration of Proposed Alternative This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on July 15, 2014.

7.4. Impracticality of Compliance Component configuration:

• Surface 1: Forged Stainless Pipe

• Surface 2: Cast Stainless Flow Restrictor

• Diameter: 10.0 in.

• Thickness: 1.0 in.

This component was scanned manually with conventional methods. Scanning requirements are described in 10 CFR 50.55a(b)(2)(xv)(A)(1). These requirements describe and are specific to scanning components in two axial and two circumferential directions. This component was scanned to the extent possible to meet these requirements. The aggregate coverage that was obtained is described and calculated from the following:

• 600 shear waves obtained 50% coverage in one axial direction (S1 - pipe)

• 600 shear waves obtained 0% coverage in one axial direction (S2 - flow restrictor)

• 450 shear waves obtained 50% coverage in one axial direction (S3 - CW)

• 450 shear waves obtained 50% coverage in one axial direction (S4 - CCW)

The aggregate coverage was calculated to be (50% + 0 + 50% + 50%)/4 = 37.5%.

Best effort supplemental scanning was also performed using 600 refracted longitudinal waves for interrogation of the lower 1/3 flow restrictor far side of the weld from the S1 pipe side, but is not qualified to be calculated into the above claimed coverage. The supplemental refracted longitudinal scan was only used for interrogation in the axial direction per procedural direction. Supplemental scanning is not performed in the circumferential direction.

Page 18 of 55

Oconee Relief Request 12-ON-001 The impracticality was caused by the cast stainless steel material which cannot be effectively interrogated by ultrasound. There are currently no examination techniques that have been qualified through Appendix VIII for cast stainless steel. Therefore, coverage could not be obtained by scanning from the flow restrictor side. In order to scan all of the required volume for this weld, the valve would have to be redesigned and replaced, which is impractical.

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

This relief request is specific to examination volume coverage limitations only. All other Code requirements were satisfied.

No indications were recorded during this examination. The reject box on each UT Calibration/Examination sheet is marked for internal tracking of the coverage limitation only.

7.5. Proposed Alternative and Basis for Use This weld was examined using procedures, equipment and personnel qualified in accordance with ASME Section Xl, Appendix VIII. Radiography (RT) is not a desired option because RT is limited in the ability to detect service induced flaws and has not been qualified through performance demonstration. Use of other manual or automated UT techniques, whether conventional or phased array, qualified under ASME Section XI, Appendix VIII would not increase coverage due to the limitation created by the cast stainless material. The use of any other UT technique available would incur the same physical scanning limitations.

13.4. Impracticality of Compliance Component configuration:

• Surface 1: Cast Stainless Steel Valve

• Surface 2: Forged Stainless Steel Tee

• Diameter: 4.0 in.

• Thickness: 0.531 in.

This component was scanned manually with conventional methods. Scanning requirements are described in 10 CFR 50.55a(b)(2)(xv)(A)(1). These requirements describe and are specific to scanning components in two axial and two circumferential directions. This component was scanned to the extent possible to meet these requirements. The aggregate coverage that was obtained is described and calculated from the following:

• 600 shear waves obtained 0% coverage in one axial direction (S1 - valve)

• 600 shear waves obtained 50% coverage in one axial direction (S2 - tee)

• 450 shear waves obtained 50% coverage in one axial direction (S3 - CW)

• 450 shear waves obtained 50% coverage in one axial direction (S4 - CCW)

The aggregate coverage was calculated to be (0% + 50% + 50% + 50%)/4 = 37.5%.

Best effort supplemental scanning was also performed using 700 refracted longitudinal waves for interrogation of the lower 1/3 valve far side of the weld from the S1 tee side, but is not qualified to be calculated into the above claimed coverage. The supplemental refracted longitudinal scan was only used for interrogation in the axial direction per procedural direction. Supplemental scanning is not performed in the circumferential direction.

The impracticality was caused by the cast stainless steel material which cannot be effectively interrogated by ultrasound. There are currently no examination Page 36 of 55

Oconee Relief Request 12-ON-001 techniques that have been qualified through Appendix VIII for cast stainless steel. Therefore, coverage could not be obtained by scanning from the valve side. In order to scan all of the required volume for this weld, the valve would have to be redesigned and replaced, which is impractical.

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

This relief request is specific to examination volume coverage limitations only. All other Code requirements were satisfied.

No indications were recorded during this examination. The reject box on each UT Calibration/Examination sheet is marked for internal tracking of the coverage limitation only.

13.5. Proposed Alternative and Basis for Use This weld was examined using procedures, equipment and personnel qualified in accordance with ASME Section XI, Appendix VIII. Radiography (RT) is not a desired option because RT is limited in the ability to detect service induced flaws and has not been qualified through performance demonstration. Use of other manual or automated UT techniques, whether conventional or phased array, qualified under ASME Section XI, Appendix VIII would not increase coverage due to the limitation created by the cast stainless material. The use of any other UT technique available would incur the same physical scanning limitations.

13.6. Duration of Proposed Alternative This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on July 15, 2014.

The reject box on each UT Calibration/Examination sheet is marked for internal tracking of the coverage limitation only.

19.5. Proposed Alternative and Basis for Use No substitution alternative for this weld is available which would provide better coverage. Radiography (RT) is not a desired option because RT is limited in the ability to detect service induced flaws. Use of other manual or automated UT techniques, whether conventional or phased array, were considered, but would not increase coverage due to the limitation created by the component configuration. The use of any other UT technique available would incur the same physical scanning limitations, 19.6. Duration of Proposed Alternative This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on July 15, 2014.

19.7. Justification for Granting Relief Ultrasonic examination of the weld for the item number PSI was conducted using personnel, equipment, and procedures qualified in accordance with ASME Section XI, 1998 Edition with the 2000 Addenda.

The system leakage test performed each refueling outage in accordance with Table IWB-2500-1, Examination Category B-P requires a VT-2 visual examination to detect evidence of leakage. This test and VT-2 examination provides additional assurance of pressure boundary integrity.

In addition to the above Code required examinations (volumetric and pressure test), Reactor Building Normal Sump monitoring and other leakage detection systems provide additional assurance that, in the event that leakage did occur through this weld, it would be detected and proper action taken.

Duke Energy has examined the weld to the maximum extent possible utilizing approved examination techniques and equipment. Based on the acceptable results for the coverage completed by the volumetric examination, the pressure testing (VT-2) examinations required by Section XI, and the leakage monitoring, it is Duke Energy's position that the combination of examinations provides a reasonable assurance of quality and safety.

Oconee Relief Request 12-ON-001 20.0 Weld WJ36 (Serial #N-32389-1) 20.1. ASME Code Component(s) Affected Unit 1 Letdown Cooler SN# N-32389-1 Outlet Nozzle to Channel Body Weld

1. WJ36, Summary Number PSI and ASME Code Class 1.

20.2. Applicable Code Edition and Addenda ASME Boiler and Pressure Vessel Code,Section XI, 1998 Edition through the 2000 Addenda.

20.3. Applicable Code Requirement IWB-2500, Table IWB-2500-1, Examination Category B-D, Item Number B3.150 Figure IWB-2500-7(a), 100% Volume Coverage of Examination Volume A-B-C-D-E-F-G-H-I.

20.4. Impracticality of Compliance Component configuration:

• Surface 1: Stainless Steel Channel Body

• Surface 2: Stainless Steel Outlet Nozzle

• Diameter: 3.0 in.

• Thickness: 0.875 in.

This component was scanned manually using conventional methods. Scanning requirements are described in ASME Section XI, Appendix III, 111-4420 and 111-4430. These requirements describe and are specific to scanning components in two axial and two circumferential directions. This component was scanned to the extent possible to meet these requirements. The aggregate coverage that was obtained is described and calculated from the following.

0 Base metal coverage using circumferential and axial scan coverage: 450 shear waves and 450, 600 and 700 longitudinal waves in the S1 and S2 direction obtained an aggregate coverage of 60.1%

• Weld Material coverage using axial and circumferential scan coverage:

450 shear waves obtained an aggregate coverage of 49.1 %

• The total aggregate coverage was calculated to be (49.1% + 60.1%)/2 = 54.6%

• In addition, a best effort examination was performed using 600 and 700 longitudinal waves to the extent possible in the upper 2/3 area of interest.

The impracticality was caused by the weld taper configuration of the outlet nozzle to channel body that does not allow meaningful interrogation from Surface 2, the outlet nozzle side. In order to scan the required volume for this weld, the channel body to outlet nozzle weld would have to be redesigned and replaced, which is impractical.

Page 54 of 55

Oconee Relief Request 12-ON-001 The Oconee Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage. Therefore, the available coverage will not meet the acceptance criteria of this Code Case.

This relief request is specific to examination volume coverage limitations only. All other Code requirements were satisfied.

No indications were detected during this examination. The reject box on each UT Calibration/Examination sheet is marked for internal tracking of the coverage limitation only.

20.5. Proposed Alternative and Basis for Use No substitution alternative for this weld is available which would provide better coverage. Radiography (RT) is not a desired option because RT is limited in the ability to detect service induced flaws. Use of other manual or automated UT techniques, whether conventional or phased array, were considered, but would not increase coverage due to the limitation created by the component configuration. The use of any other UT technique available would incur the same physical scanning limitations.

20.6. Duration of Proposed Alternative This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on July 15, 2014.

20.7. Justification for Granting Relief Ultrasonic examination of the weld for the item number PSI was conducted using personnel, equipment, and procedures qualified in accordance with ASME Section XI, 1998 Edition with the 2000 Addenda.
