Subject:

Duke Power Company LLC d/b/a Duke Energy Carolinas, LLC (Duke)

Oconee Nuclear Station, Unit 2 Docket Nos. 50-270 Third Ten Year Inservice Inspection Interval Request for Relief No. 04-ON-009, Revision 1 By letter dated September 13, 2004, Duke submitted Request for Relief 04-ON-009 seeking relief pursuant to 10 CFR 50.55a(g)(5)(iii), from the requirement to examine 100% of the volume specified by the ASME Boiler and Pressure Vessel Code,Section XI, 1989 Edition with no Addenda (as modified by Code Case N-460).

Subsequently, Duke recognized that a portion of the justificationfor the relief contained inaccurate wording relative to a method of detecting a leak should it develop at one of the subject welds. Duke communicated to the NRC an intent to submit a revised version of the relief to correct that issue.

Duke notes that this request applies to the third Inservice Inspection Interval for Oconee Unit 2, which terminated September 9, 2004. At this time, Duke is submitting the attached request, which is considered Revision 1 and replaces and supersedes the original request in its entirety. Duke requests NRC review and approval in order to close out the third interval documentation.

The relief would allow Duke Energy to take credit for ten (10) limited ultrasonic examinations on welds associated with various systems and components described in the request.

During examination of the subject Unit 2 welds, the ultrasonic examination coverage did not meet the 90% examination requirements of Code Case N-460.

The obtainable volume coverage for each weld examination is indicated on the attached request. Achievement of greater examination coverage for these welds was impractical due to piping/valve geometry, interferences, and existing

1. ASME Code Component Affected Letdown Cooler 2B High Pressure Injection System Inlet Nozzle to Channel Head Weld Weld ID = 2-LDCB-INLET-V I Item Number/Summary Number = B03. 150.003 II. Applicable Code Edition and Addenda ASME Section XI Code - 1989 Edition with no Addenda III. Applicable Code Requirement IWB-2500, Table IWB-2500- 1, Examination Category B-D, Item Number B3.150 Fig. IWB-2500-7 (a), 100% Volume Coverage of Examination Volume A-B-C-D-E-F-G-H-I-J IV. Impracticality of Compliance The Letdown Cooler Inlet Nozzle and Channel Head material is SA 182 Grade T316L.

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%

coverage of the required examination volume was obtained for this weld. The percentage of coverage reported represents the aggregate coverage from all scans performed on the weld and adjacent base material. The coverage from each scan was as follows: 450 scan perpendicular and parallel to the weld covered 28%; 60' scan perpendicular and parallel to the weld covered, 29%. 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 order to scan all of the required surfaces for the inspection of these welds, 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.

The Oconee Inservice Inspection Plan allows the use-of Code Case N-460, which recquires greater than 90% volumetric coverage of examination volume A-B-C-D-E-F-G-H-l-J:

therefore, the available coverage will not meet the acceptance criteria of this Code Case.

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.

Relief Request 04-ON-009 Rev. 1 Page 3 of 29 VI. Implementation Schedule and Duration No additional examinations were planned for the areas/welds during the third inspection interval. This request is for the duration of the third inservice inspection interval, which ended on September 9, 2004.

VII. Justification for Granting Relief Ultrasonic examination of areas/welds for item number B03.150 were conducted using personnel, qu~alified in accordance with ASME Section XI, Appendix V1H of the 1995 Edition With the 1996 Addenda. The ultrasonic procedures used complied with the requirements of ASME Section V, Article 4, 1989 Edition with no addenda.

Duke wil.l use Class I, Examination Category B-P, pressure testing and VT-2 visual examination to compliment the limited scan examinations. The Code requires that a pressure test be performed after each refueling outage for Class I. These tests require a VT-2 visual examination for evidence of leakage. This testing provides adequate 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, system leak rate limitations imposed by Technical Specifications 3.4. 13, "Reactor Coolant System Leakage." as well as reactor buildCing normal sump rate monitoring, provide additional assurance that any leakage would be detected prior to gross failure of the component.

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

Applicable Code Edition and Addenda ASME Section XI Code - 1989 Edition with no Addenda III. Applicable Code Requirement RVB-2500, Table IWB-2500- l, Examination Category B-J, Item Number B9.l I Fig. IWB-2500-8 (c), 100% Volume Coverage of Examination Volume C-D-E-F IV. Impracticality of Compliance The tee and reducer material is SA-403/WP304 or WP3 6 stainless steel. This weld has a diameter of 4.0 inches and a wall thickness of1.531 inches.

During the ultrasonic examination of this weld, 88% 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 450 shear wave circumferential scans, both clockwise and counter-clockwise covered 100% of the examination vOlume and the 600 shear wave axial scan covered 77.7% from two directions. A supplemental 600 refracted longitudinal Wave scan covered 100% of the examination volume in one axial direction from the reducer side. The limitation was 4 inches long on the tee side of the weld caused by the throat of the tee. In order to scan all of the required surfaces for the inspection of this weld, the tee 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.

The Oconee Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage of examination vOlunie C-D-E-F; therefore, the available coverage will not meet the acceptance criteria of this Code Case.

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 04-ON-009 Rev. I Page 7 of 29 VI. Implementation Schedule and Duration No additional examinations were planned for the areas/welds during the third inspection interval. This request is for the duration of the third inservice inspection interval, which ended on September 9, 2004.

VII. Justification for Granting Relief Ultrasonic examination of area/weld for item number B09.011 was conducted using personnel, equipment and procedures qualified in accordance with ASME Section X1, Appendix V1ll Supplement 2 of the 1995 Edition with the 1996 Addenda as administered by the Performance Demonstration Initiative (PDM). In addition to the volumetric examination with limited coverage, Duke performed a surface examination (code required) on the B09.01 I item and achieved 100% coverage. The result of the surface examination was acceptable.

Duke does not claim credit for coverage of the far side of austenitic welds when access is limited to one side only. The characteristics of austenitic weld metal attenuate and distort the sound beamn when shear waves pass through the weld. Refracted longitudinal waves provide better penetration but cannot be used beyond the first sound 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.

The procedures, personnel and eclIpmenit have been quali fied through the PDI.

However, although 60' longituldinal wave search units and 700 shear wave search units were used in the qualification and cracks were detected through the weld metal, PDI does not provide a qualification for single sided examination of similar metal austenitic piping welds.

Duke will use Class 1, Examination Category B-P, pressure testing and VT-2 visual examination to compliment the limited scan examinations. The Code reqLuires that a pressure test be performed after each refueling outage for Class 1. These tests require a VT-2 visual examination for evidence of leakage. This testing provides adequate 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, system leak rate limitations imposed .by Technical Specifications 3.4.13, "Reactor Coolant System Leakage," as well as reactor building normal sump rate monitoring, provide additional assurance that any leakage would be detected prior to gross failure of the component.

Justification for Granting Relief Ultrasonic examination of areas/welds for the item numbers C05.02 I were conducted using personnel, equipment and procedures qualified in accordance with ASME Section XI, Appendix VII Supplement 2 of the 1995 Edition with the 1996 Addenda as administered by the PDI. In addition to the volumetric examinations with limited coverage, Duke performed a surface'examination (code required) on each of the C05.021 items and achieved 100% coverage. The results from the surface examinations were acceptable.

In addition to the C05.02 I welds that relief is being requested for limited scanning, there were I I additional C05.021 welds that surface and volumetric examinations were performed on.The examinations didn't identify any recordable indications and 100%

coverage was obtained on each of the I I welds. The I I additional welds were from the same system as the C05.02 I welds of this request.

Duke does not claim credit for coverage of the far side of auslenitic welds. The characteristics of austenitic weld metal attenuate and distort the sound beam when shear waves pass throuogh the weld. Refracted lonoitudinal 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 alstenitic welds when the nominal material thickness exceeds 0.5 inch. A 70' shearwave angle beam is used to interrogate the far side of the weld when the nominal material thickness is equal to or less than 0.5 inch and a 60' refracted longitudinal wave is uLsed to interrogate the far side of the weldwhen 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 provides adecquate assurance of pressure boundary integrity.

In addition to the above Code required examinations (volimetric 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, system leak rate limitations imposed by Technical Specifications 3.4.13, "Reactor Coolant System Leakage," as well as visual observations performed during operator rounds, provide additional assurance that any leakage would be detected prior to gross failure of the component.

Relief Request 04-ON-009 Rev. 1 Page 17 of 29 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, surface and the pressure testing (VT-2) examinations 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 A I82/F3 16 stainless steel and the pipe material is SA-3 12/TP304 stainless steel. This weld has a diameter of 3.0 inches and a wall thickness of .216 inches.

During the ultrasonic examination of this weld. 35.2% coverage of the required examination volume was obtained. The percentage ot coverage represents the aggregate coverage from all scans performed on the weld and adjacent base material. The 450 shear wave circumferential scans, both clockwise and counter-clockwise covered 50% of the examination volume and the 60W shear wave axial scan covered 40.6%. A supplemental 70' shear wave scan covered 100% of the examination Volume in one axial direction fiom the pipe side. The limitation vWas caused by the taper on the valve side of the weld which prevented scanning from that side. In order to scan Lill of the required surfaces for the inspection of 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.

The Oconee Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage of ex amination volume C-D-E-F; therefore, the available coverage will not meet the acceptance criteria of this Code Case.

V. Proposed Alternate Examinations or Testin2 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.

450 shear wave beam covered 50% of the required volume in two circumferential and two tangential directions. (Cross hatched area) 600 RL beam covered *0.048 sq. in. on the valve side of the weld. This equates to 18.89% of the required examination volume.

.048+.254 100= 18.89%

This limitation was caused by the valve configuration which prevents scanning on the valve side of the weld. Reported coverage is the aggregate of all scans performed on the weld.
