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., Site Vice President Attachment A Attachment B www. duke-energy.

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.

This weld has a diameter of NPS 3.0 inches and a wall thickness of 0.875 inches.The ultrasonic examination of this weld obtained 54.6% coverage of the required examination volume. Scanning requirements are described in 10CFR.50.55a(b)(2)(xv) (A)(1). The aggregate coverage was calculated from the following:

The limitation was caused by the weld taper configuration created by the attachment of the nozzle to the channel body. In order to scan all of the required volume for this weld, the nozzle to channel body would have to be redesigned to allow scanning from both sides of the weld, which is impractical.

Impracticality of Compliance The pipe and tee material is stainless steel. This weld has a diameter of NPS 2.5 inches and a wall thickness of .375 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: 600 shear waves obtained 50% coverage in one axial direction (S1 -pipe)* 600 shear waves obtained 0% coverage in one axial direction (52 -tee)* 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 tee would have to be redesigned, 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.Page 30 of 57

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.

No substitution alternative for this weld is available which would provide better coverage.15.6.

Justification for Granting Relief Ultrasonic examination of the weld for the item number 01 .C5.21.0040 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 C5.21 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 Xl, and the leakage monitoring, it is Duke's position that the combination of examinations provides a reasonable assurance of quality and safety.Page 31 of 57 IOCONEE RELIEF REQUEST # 11 ON 0011 16.0 Weld #1-51A-02-16BH 16.1.

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.

23.6. Duration of Proposed Alternative This request is for the duration of the fourth inservice inspection interval, currently scheduled to end on July 15, 2014 23.7. Justification for Granting Relief Ultrasonic examination of the weld for the item number 02.B9.11.0053 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.Page 47 of 57
