Subject:

Duke Energy Oconee Nuclear Station, Unit 2 Docket Nos. 50-270 Third Ten Year Inservice Inspection Interval Requests for Relief No. 04-ON-009 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 ASME Boiler and Pressure Vessel Code,Section XI, 1989 Edition with no Addenda (as modified by Code Case N-460).

Request for Relief 04-ON-009 is to allow Duke Energy to take credit for ten (10) limited ultrasonic examinations on welds associated with various systems and components described in the attached 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 is impractical due to piping/valve geometry, interferences, and existing examination technology. Therefore, Duke Energy requests that the NRC grant relief as authorized under 10 CFR 50.55a(g) (6) (i).

Note: Items in this relief request were inspected during one of the following months: February, March, or April of 2004.

Relief Request 04-ON-009 Page 4 of 8 IV. & V. Impracticalitv/Burden caused by Code Compliance Paragraph A: (The Letdown Cooler Inlet Nozzle and Channel Head material is SA182 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%; 600 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.

Paragraph B: (The Letdown Cooler Outlet Nozzle and Channel Head material is SA182 Grade T316L. This weld has a diameter of 3.0 inches and a wall thickness of .875 inches.)

During the ultrasonic examination of the Outlet Nozzle to Channel Head weld, 29. % coverage of the required examination volume was obtained. 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 outlet 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.

Paragraph C: (The tee and reducer material is stainless steel. This weld has a diameter of 4.0 inches and a wall thickness of .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 45° shear wave circumferential scans, both clockwise and counter-clockwise covered 100% of the examination volume and the 60° shear wave axial scan covered 88% 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.

Paragraph D: (The pipe and valve material is stainless steel. This weld has a diameter of 4.0 inches and a wall thickness of .531 inches.)

During the ultrasonic examination of this weld, 34% 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 50% of the examination volume and the 600 shear wave axial scan covered 34%. A supplemental 600 refracted longitudinal wave scan covered 100% of the examination volume in one axial direction from the pipe side. Limitations were caused by the taper on the valve side of the weld which prevented scanning from that side. In order to scan all 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 limitation was caused by the taper on the valve side of the weld which prevented scanning from that side. In order to scan all 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.

Paragraph G: (The pipe and valve material is 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% 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 50% of the examination volume and the 600 shear wave axial scan covered 35%. A supplemental 700 shear wave scan covered 100% of the examination volume in one axial direction from the pipe side. The limitation was caused by the taper on the valve side of the weld which prevented scanning from that side. In order to scan all 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.

Paragraph H: (The tee and pipe material is stainless steel. This weld has a diameter of 3.0 inches and a wall thickness of .438 inches.)

During the ultrasonic examination of this weld, 86% coverage of the required examination volume was obtained.

VI. Proposed Alternate Examinations or Testing Paragraph K:

The scheduled 10-year code examination was performed on the referenced area/weld and it resulted in the noted limited coverage of the required ultrasonic volume. These inspections were performed during the last inspection outage of the interval; no additional examinations are planned for the area/weld during the current inspection interval.

VII Implementation Schedule and Duration Paragraph L The scheduled third 10-year interval plan code examination was performed on the referenced areas/welds resulting in limited scan and volumetric coverage. No additional examinations are planned for the areas/welds during the current inspection interval. The same areas/welds may be examined again as part of the next (fourth) 10-year interval plan, depending on the applicable code year edition and addenda requirements adopted in the future.

VIII. Justification for Grantine Relief Paragraph M:

Ultrasonic examination of areas/welds for item number B03.150 were conducted using personnel, qualified in accordance with ASME Section XI, Appendix VII 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.

Although 100% coverage of the examination volume could not be achieved, the amount of coverage obtained for this examination provides an acceptable level of quality and integrity. (See Paragraph 0 for additional justification.)

Paragraph N:

Ultrasonic examination of area/weld for item number B09.011 was conducted using personnel, equipment and procedures qualified in accordance with ASME Section XI, Appendix VIII Supplement 2 of the 1995 Edition with the 1996 Addenda as administered by the Performance Demonstration Initiative (PDI). Although 100% of the required scanning could not be achieved, the amount of coverage of the examination volume obtained for this weld provides an acceptable level of quality and integrity. In addition to the volumetric examination with limited coverage, Duke Energy performed a surface examination (code required) on the B09.011 item and achieved 100%

coverage. The result of the surface examination was acceptable. (See Paragraph 0 for additional justification.)

Duke Energy Corporation 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 beam when shear waves pass through the weld. Refracted longitudinal waves provide better penetration but cannot be used beyond the first sound path leg. Duke Energy Corporation uses a combination of shear waves and longitudinal waves to examine

Relief Request 04-ON-009 Page 7 of 8 single sided austenitic welds when the nominal material thickness exceeds 0.5 inch. A 60° 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 equipment have been qualified through the PDI. However, although 600 longitudinal 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.

Paragraph 0:

Duke Energy will use Class 1, 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 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 these welds, it would be detected and isolated. Specifically, leakage from these welds would be detected by monitoring of the Reactor Coolant System (RCS), which is performed once each shift under procedure PT/2/A/0600/10, "RCS Leakage". This RCS leakage monitoring is a requirement of Technical Specification 3.4.13, "Reactor Coolant System Leakage".

Any leakage is also evaluated in accordance with this Technical Specification. The leakage could also be detected through several other methods. One is the RCS mass balance calculation. A second is the Reactor Building air particulate monitor. This monitor is sensitive to low leak rates; the iodine monitor, gaseous monitor and area monitor are capable of detecting any fission products in the coolant and will make these monitors sensitive to coolant leakage. A third is the level indicator in the Reactor Building normal sump. A fourth is a loss of level in the Letdown Storage Tank. Based on the results of the required volumetric, surface and VT-2 examinations performed during this outage, it's Duke's belief that this combination of examinations provides a reasonable assurance of component integrity.

Paragraph P:

Ultrasonic examination of areas/welds for the item numbers C05.021 were conducted using personnel, equipment and procedures qualified in accordance with ASME Section A, Appendix vm Supplement 2 of the 1995 Edition with the 1996 Addenda as administered by the PDI. Although 100% coverage of the examination volume could not be achieved, the amount of coverage obtained for each of these welds provides an acceptable level of quality and integrity. In addition to the volumetric examinations with limited coverage, Duke Energy 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 C05.021 welds that relief is being requested for limited scanning, there were 11 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 11 welds. The 11 additional welds were from the same system as the C05.021 welds of this request.

Duke Energy Corporation does not claim credit for coverage of the far side of austenitic welds. The characteristics of austenitic weld metal attenuate and distort the sound beam when shear waves pass through the weld. Refracted longitudinal waves provide better penetration but cannot be used beyond the first path leg. Duke Energy Corporation 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 700 shear wave 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 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.

Duke Energy 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 adequate assurance of pressure boundary integrity.

Relief Request 04-ON-009 Page 8 of 8 In addition to the above Code required examinations (surface and pressure test), there are other activities which provide a high level of confidence that, in the unlikely case that leakage did occur through these welds, it would be detected and isolated. One is that leakage from these welds would be detected by Operations personnel during their regular rounds (reference procedure OP/2/A/1 102/020A Primary Rounds"). The Nuclear Equipment Operator has been trained to look for any unusual conditions, such as leaks. In addition, the procedure addresses leaks as being an item to consider during rounds. The C05.021 items in this request are located in an area where operations personnel will be walking through as part of their rounds; therefore, any leak would be identified by visual observation. This paragraph is applicable to all C05.021 items (except for C05.021.058) which are located in the aux building (HPI room).

Item C05.021.058 is located in the reactor building and the additional measures listed in the second paragraph of Paragraph 0 would be applicable for this item.

Duke Energy has examined the welds/components referenced in this request to the maximum extent possible utilizing the latest in examination techniques and equipment. The welds/components identified in Section II of this request were 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 exams and surface exams this outage and the pressure testing (VT-2) exams, it is Duke's belief that this combination of examinations provides a reasonable assurance of component integrity.
