Subject:

Duke Energy Oconee Nuclear Station, Unit 1 Docket Nos. 50-269 Fourth Ten Year Inservice Inspection Interval Request for Relief No. 05-ON-004 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, 1998 Edition with 2000 Addenda (as modified by Code Case N-460).

Request for Relief 05-ON-004 is to allow Duke Energy to take credit for four (4) limited ultrasonic examinations on welds associated with various systems and components described in the attached request.

The ultrasonic examination coverage of the subject Unit 1 welds 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 requests. 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).

If there are any questions or further information is needed you contact R. P. Todd at (864) 885-3418.

Relief Request 05-ON-004 Page 2 of 4 IV. & V. ImpracticalitvlBurden Caused by Code Compliance Paragraph A: (The Reactor Coolant Pump Inlet Nozzle material is A351 CF-8 and the Safe-End material is A376 TP 316. This weld has a diameter of 36.5 inches and a wall thickness of 2.330 inches.)

During the ultrasonic examination of this weld, 37.50% 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 shear wave scan parallel to the weld both clockwise and counter-clockwise covered 50% of the weld and base material; 600 shear wave scan perpendicular to the weld covered 50% of the weld and base material in one axial direction. A supplemental scan using a 600 refracted longitudinal wave search unit covered 50% of the weld and adjacent base material from one direction perpendicular to the weld including 100% of the inside surface within the area of interest. The reactor coolant pump inlet nozzle configuration prevented scanning from both sides of the weld. In order to scan all of the required volume for this weld, 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 valve and elbow material is stainless steel. This weld has a diameter of 4.0 inches and a wall thickness of.53 inches.)

During the ultrasonic examination of this weld, 37.50% 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 coverage from each scan was as follows: 450 shear wave circumferential scans, both clockwise and counter-clockwise covered 50% of the weld and base material; 600 shear wave scan perpendicular to the weld covered 50% of the weld and base material from one axial direction. A supplemental scan using a 600 refracted longitudinal wave search unit covered 50% of the weld and adjacent base material from one direction perpendicular to the weld including 100% of the inside surface within the area of interest. 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 volume for 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 C: (The valve and pipe material is stainless steel. This weld has a diameter of 4.0 inches and a wall thickness of.53 inches.)

During the ultrasonic examination of this weld, 37.50% 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 coverage from each scan was as follows: 45° shear wave circumferential scans, both clockwise and counter-clockwise covered 50% of the weld and base material; 60° shear wave scan perpendicular to the weld covered 50% of the weld and base material from one axial direction. A supplemental scan using a 60° refracted longitudinal wave search unit covered 50% of the weld and adjacent base material from one direction perpendicular to the weld including 100% of the inside surface within the area of interest. 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 volume for 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.

Proposed Alternate Examinations or Testing Paragraph D:

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 first inspection outage of the interval; no additional examinations are planned for the area/weld during the current inspection interval.

Relief Request 05-ON-004 Page 3 of 4 VII. Implementation Schedule and Duration Paragraph E The scheduled fourth 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 (fifth) 10-year interval plan, depending on the applicable code year edition and addenda requirements adopted in the future.

VIII. Justification for Granting Relief Paragraph F:

Ultrasonic examination of areas/welds for item number B09.011 were conducted using personnel, equipment and procedures qualified in accordance with ASME Section Xl, Appendix VIII 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 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 this weld and achieved 100% coverage. The result from the surface examination was acceptable.

In addition to the B09.01 1 weld that relief is being requested for limited volume coverage, there were 4 additional B09.011 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 them. The 4 additional welds were from the same system as the B09.01 1 weld of this request.

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, surface, 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 isolated. Specifically, leakage from this weld would be detected by monitoring of the Reactor Coolant System (RCS), which is performed once each shift under procedure PT/1/A10600/10, "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 method 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 making these monitors sensitive to coolant leakage. A second is the level indicator in the Reactor Building normal sump. A third 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 is Duke's belief that this combination of examinations provides a reasonable assurance of component integrity.

Paragraph G:

Ultrasonic examination of areas/welds for the item numbers C05.021 were 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 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 volume coverage, there were 7 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 them. The 7 additional welds were from the same system as the C05.021 welds of this request.

Relief Request 05-ON-004 Page 4 of 4 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.

In addition to the above Code required examinations (volumetric, 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/l/ANI 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.

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, surface exams, and the pressure testing (VT-2) exams during this outage, it is Duke's belief that this combination of examinations provides a reasonable assurance of component integrity.
