Subject:

Duke Energy Carolinas, LLC Oconee Nuclear Station Units 2 and 3 Docket No. 50-270, -289 Fourth Ten-Year Inservice Inspection Plan Request for Relief No. 11-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).The attached Request for Relief 11-ON-002 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 2 EOC23 and Unit 3 EOC24 and Unit 3 EOC25 refueling outages. The ultrasonic examination coverage of the subject Unit 1, and 2 welds did not meet the 90% examination requirements of Code Case N-460. The obtainable volume coverage for weld examination is indicated on Attachments A, B and C 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). If there are any questions or further information is needed you may contact Corey Gray at (864)-873-6325.

ASME Code Component(s) Affected Unit 2 Pressurizer Heater Belt Shell to Sampling Nozzle Weld, Weld #2-PZR-WP26-7, Summary Number 02.B3.1110.0012 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 B3.110 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 The pressurizer Heater Belt shell material is carbon steel and the sampling nozzle material is carbon steel. This weld has a diameter of 5.750 inches and a wall thickness of 6.187 inches.Because of the weld configuration, the requirements of 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 could not be met. The aggregate coverage was calculated from the following base and weld metal scan results: Weld coverage using 350, 450& 600 shear waves for axial scans (S1, S2), and 35° & 450 shear waves for circ. scans (CW, CCW) obtained 17.2% coverage.Base material coverage using 350, 450& 600 shear wave for axial scans (SI) and 35°& 450 shear waves for circ. scans (CW, CCW)obtained 54.0% coverage.* 00 scan coverage obtained 37.5% coverage.* The aggregate coverage was calculated to be (17.2% + 54.0% +37.5%)/3 = 36.2%.The limitation was caused by the weld taper configuration created by the attachment of the sampling nozzle to the Heater Belt shell not allowing scanning from Surface 2. In order to scan all of the required volume for this weld, the upper shell to sampling nozzle attachment weld would have to be redesigned to allow scanning from both sides of the weld, which is impractical. Page 4 of 71 Relief Request 11 ON 002 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.2.5. Proposed Alternative and Basis for Use No substitution alternative for this weld is available which would provide better coverage.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 02.B3.110.0012 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 provides additional assurance that, in the event that leakage did occur through this weld, it would be detected and proper action taken.Duke has examined the weld/component 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 Xl, and the leakage monitoring, it is Duke's position that the combination of examinations provides a reasonable assurance of quality and safety.Page 5 of 71 Relief Request 11 ON 002 3.0 Weld #2-PIB2-8 3.1.

Applicable Code Requirement IWB-2500, Table IWB-2500-1, Examination Category B-J, Item Number B9.11 Figure IWB-2500-8 (c), 100% Volume Coverage of Examination Volume C-D-E-F 3.4. Impracticality of Compliance This item is a cast stainless steel pump casing nozzle welded to a stainless steel safe end. This weld has a diameter of 33.50 inches and a wall thickness of 2.33 inches.Scanning requirements are described in 1OCFR.50.55a(b)(2)(xv) (A)(1). The aggregate coverage was calculated from the following:

• 600 shear waves obtained 0% coverage in one axial direction (S1 -nozzle)0 600 shear waves obtained 50% coverage in one axial direction (S2 -pipe)0 450 shear waves obtained 50% coverage in one circ. directions (S3 -CW)0 450 shear waves obtained 50% coverage in one circ. directions (S4 -CCW)* The aggregate coverage was calculated to be (0% + 50% + 50% +50%)/4 = 37.5%.0 60' longitudinal waves obtained 47.3% supplemental coverage beyond the weld centerline in one axial direction (S2 -pipe). This is not included in the aggregate coverage.0 In addition, a best effort examination was performed in two axial directions (S1, S2) using 600 and 700 longitudinal waves to the extent possible in the upper 2/3 area of interest.The individual scan results are recorded on the form labeled "Determination of Percent Coverage for UT Examinations

-Pipe. The limitation was caused by the cast stainless material and the weld taper configuration created by the attachment of the nozzle to safe end configuration. In order to scan all of the required volume for this weld, the pump would have to be replaced with Page 6 of 71 Relief Request 11 ON 002 forged stainless steel and would have to be redesigned to allow scanning from both sides of the weld, which is impractical. 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.3.5. Proposed Alternative and Basis for Use 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. 3.6.

The result from the surface examination was acceptable. The system leakage test performed each inspection period in accordance with Table IWC-2500-1; Examination Category C-H 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, surface, and pressure test), visual observations performed during operator rounds provide additional assurance that in the event leakage did occur through this weld, it would be detected and proper action taken.Duke has examined the weld/component 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 acceptable results of the surface examinations performed during this outage, the pressure testing (VT-2) examinations required by Section Xl, and the continuing periodic leakage inspections, it is Duke's position that the combination of examinations provides a reasonable assurance of quality and safety.Page 31 of 71 Relief Request 11 ON 002 16.0 Weld #2HP-221-22 16.1.

Impracticality of Compliance This item is a cast stainless steel valve welded to stainless steel seamless pipe. This weld has a diameter of 4.0 inches and a wall thickness of .531 inches.Scanning requirements are described in 10CFR.50.55a(b)(2)(xv)(A)(1). The aggregate coverage was calculated as follows:* 600 shear waves obtained 50% coverage in one axial direction (51 -elbow)0 600 shear waves obtained 0% coverage in one axial direction (S2 -valve)* 450 shear waves obtained 50% coverage in one circ. direction (S3 -CW)* 450 shear waves obtained 50% coverage in one circ. direction (S4 -CCW)* The aggregate coverage was calculated to be (50% + 0% +50% +50%)/4 = 37.5%In order to scan all of the required volume for this weld, the valve would have to be replaced with forged stainless steel, 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.Page 32 of 71 Relief Request 11 ON 002 16.5. Proposed Alternative and Basis for Use 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. 16.6.

The aggregate coverage was calculated from the following: 600 shear waves obtained 100% coverage in one axial direction (S1 -valve)600 shear waves obtained 100% coverage in one axial direction (S2 -pipe)* 450 shear waves obtained 50% coverage in one circ. direction (CW).* 450 shear waves obtained 50% coverage in one circ. direction (CCW).* The aggregate coverage was calculated to be (100% + 100% + 50%+ 50%)/4 = 75.0%.The limitation was caused by the valve configuration. In order to scan all of the required volume for this weld, the valve would have to be redesigned, 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.Page 48 of 71 Relief Request 11 ON 002 24.5. Proposed Alternative and Basis for Use This weld was examined using procedures, equipment, and personnel qualified in accordance with ASME Section XI, Appendix VIII.

ASME Section XI, Appendix III, 111-4420 requires coverage of the examination volume in two beam path directions and 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 aggregate coverage was calculated from the following base and weld metal scan results: Axial scan coverage: 450 shear waves and 450, 600, and 700 longitudinal waves in the S1 and S2 direction obtained an aggregate coverage of 97.2%.* Circ scan coverage: 450 shear waves obtained an aggregate coverage of 78.1%.* The total aggregate coverage was calculated to be (97.2% + 78.1% =175.3%)/2 = 87.7%.The component limitation was caused by the taper configuration of the chemical connector and the proximity of a nozzle within the scan area from the channel body. In order to scan all of the required volume for this component, the chemical connector and location of the adjacent nozzle would have to be redesigned to allow complete scanning from both sides of the weld, which is impractical.

Proposed Alternative and Basis for Use This weld was examined using procedures, equipment, and personnel qualified in accordance with ASME Section XI, Appendix VIII. 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 service induced flaws. Additionally, radiography has not been qualified through performance demonstration. 31.6.

The result from the surface examination was acceptable. 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, surface, and pressure test), Reactor Building Normal Sump monitoring provides additional assurance that, in the event that leakage did occur through this weld, it would be detected and proper action taken.Duke has examined the weld/component 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 acceptable results of the surface examinations, the pressure testing (VT-2) examinations required by Section Xl, and the leakage monitoring, it is Duke's position that the combination of examinations provides a reasonable assurance of quality and safety.Page 63 of 71 Relief Request 11 ON 002 32.0 Weld #3-PDA2-1 32.1.

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 continuing periodic leakage inspections, it is Duke's position that the combination of examinations provides a reasonable assurance of quality and safety.Page 71 of 71 AT TACHMENJ PASE I OF ýýft uke Site/Unit: Oconee I Summary No.: 02.8 Workscope: UT Vessel LAamination 2 3.110.0012 Procedure: Procedure Rev: Work Order No.: NDE-640 4 01793547 Outage No.: O2-23 Report No.: UT-08-169 Page: 1 of I ISI Code: 1998 Cat./Item: B-D 113.110 Location: Drawing No.: ISI-OCN2-002
