Subject:

Duke Energy Carolinas, LLC Oconee Nuclear Station Units 1 and 2 Docket No. 50-269, -270 Fourth Ten-Year Inservice Inspection Plan Request for Relief No. 11-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 1 1-ON-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 EOC25 and Unit 2 EOC24 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 and B 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.

Sincerely, leston Gillespie Jr.,

[OCONEE RELIEF REQUEST # 11 ON 0011 2.0 Weld #1-PZR-WP26-4 2.1. ASME Code Component(s) Affected Unit 1 Pressurizer Upper Shell to Sampling Nozzle Weld, Weld #1-PZR-WP26-4, Summary Number 01 .B3.110.0006 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

  • Surface 1: Shell - Carbon steel
  • Surface 2: Sampling nozzle - Carbon steel
  • Diameter: 5.750 in.
  • Thickness: 6.187 in.

The ultrasonic examination of this weld obtained 34.7% coverage of the required examination volume. 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 350 & 450 shear waves for circ. scans (CW, CCW) obtained 15.4%

coverage.

Base material coverage using 350, 450& 600 shear wave for axial scans

($1) and 350& 450 shear waves for circ. scans (CW, CCW) obtained 54.8% coverage.

  • 00 scan coverage obtained 33.9% coverage.
  • The aggregate coverage was calculated to be (15.4% + 54.8% +

33.9%)/3 = 34.7%.

The limitation was caused by the design of the sampling nozzle not allowing for scanning from the nozzle side of the weld. In order to scan all of the required volume for this weld, the nozzle 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 of examination volume A-B-C-D-E-F-G-H-I. The achieved coverage did not meet the acceptance criteria of this Code Case.

Page 4 of 57

[OCONEE RELIEF REQUEST # 11 ON 0011 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 01 .B3.110.0006 was conducted using personnel, equipment, and procedures qualified in accordance with ASME Section Xl, 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.

  • Diameter: 5.750 in.
  • Thickness: 6.187 in.

The ultrasonic examination of this weld obtained 34.7% coverage of the required examination volume.

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 350 & 450 shear waves for circ. scans (CW, CCW) obtained 15.4%

Applicable Code Edition and Addenda ASME Boiler and Pressure Vessel Code, Section Xl, 1998 Edition through the 2000 Addenda 12.3. Applicable Code Requirement IWC-2500, Table IWC-2500-1, Examination Category C-F-I, Item Number C5.11 Figure IWC-2500-7(a), 100% Volume Coverage of Examination Volume C-D-E-F 12.4. Impracticality of Compliance The valve material is cast stainless steel and the pipe material is stainless steel.

This weld has a diameter of NPS 10.0 inches and a wall thickness of 1.125 inches.

During the ultrasonic examination of this weld, 37.50% coverage of the required examination volume was obtained. Scanning requirements are described in 10CFR.50.55a(b)(2)(xv)(A)(1). The aggregate coverage was calculated as follows:

  • 450 shear waves obtained 0% coverage in one axial direction (S1 - valve)
  • 450 shear waves obtained 50% coverage in one axial direction (S2 -

pipe)

  • 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 (0% + 50% +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. There were no recordable indications found during the examination 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.

28.0 Weld #2-HP-0396-23 28.1 ASME Code Component(s) Affected Unit 2 Pipe to Valve 2HP-140 Weld, Weld #2-HP-0396-23, PSI 28.2 Applicable Code Edition and Addenda ASME Boiler and Pressure Vessel Code, Section Xl, 1998 Edition through the 2000 Addenda 28.3 Applicable Code Requirement IWC-2500, 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 28.4 Impracticality of Compliance Component configuration:

  • Surface 1: Cast stainless steel valve
  • Surface 2: Stainless steel pipe
  • NPS: 4.0 in.
  • Thickness: 0.531 in.

Scanning requirements are described in 10CFR.50.55a(b)(2)(xv) (A)(1). The aggregate coverage was calculated from the following:

  • 600 shear waves obtained 0.0% coverage in one axial direction (SI -

valve)

  • 600 shear waves obtained 50% 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 (0.0% + 50% + 50% +

50%)/4 = 37.5%.

The limitation was caused by the valve material and taper of the body. 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 of examination volume C-D-E-F. Therefore, the available coverage will not meet the acceptance criteria of this Code Case.

[OCONEE RELIEF REQUEST # 11 ON 0011 28.5 Proposed Alternative and Basis for Use This weld was examined using procedures, equipment, and personnel qualified in accordance with ASME Section Xl, Appendix VIII. 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.

28.6 Duration of Proposed Alternative This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on July 15, 2014 28.7 Justification for Granting Relief Ultrasonic examination of the weld for the PSI was conducted using personnel, equipment, and procedures qualified in accordance with ASME Section Xl, 1998 Edition with the 2000 Addenda.

In addition to the volumetric examination with limited coverage, Duke performed a surface examination (code required) on this PSI item. 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 XI, and the leakage monitoring, it is Duke's position that the combination of examinations provides a reasonable assurance of quality and safety.
