Subject:

Duke Energy Oconee Nuclear Station, Unit 3 Docket Nos. 50-287 Third Ten Year Inservice Inspection Interval Requests for Relief No. 04-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, 1989 Edition with no Addenda (as modified by Code Case N-460).

Request for Relief 04-ON-004 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 3 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).

Weld 3-PDB2-1 has a diameter of 33.5 inches and a wall thickness of 2.33 inches.)

During the ultrasonic examination of weld 3-PDB2-1, only 37.5% coverage of the required examination volume was obtained. The coverage reported represents the aggregate coverage of all scans performed. A 450 shear wave scan covering 50% of the required examination volume was performed on the wrought safe end side of the weld in two circumferential directions and a 600 shear wave and 600 longitudinal wave scan covering 50% of the examination volume on the wrought safe end side was performed in one axial direction from the safe end side. No scanning was performed from the cast stainless steel nozzle side of the weld. Scanning limitations were caused by the configuration the reactor coolant pump nozzle which prevented scanning from both sides of the weld. In order to scan all of the required surfaces for the inspection of this weld, the reactor coolant pump 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.

V. Alternate Examinations or Testing Paragraph K:

The scheduled 10-year code examination was performed on the referenced weld and it resulted in the noted limited coverage of the required ultrasonic volume. No additional examinations are planned for the weld during the current inspection interval.

Relief Request 04-ON-004 Page 7 of 8 VI. Justification for Granting Relief Paragraph L:

Ultrasonic examination of 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 PDI. Although 100% of the required scanning could not be achieved, the amount of coverage of the examination volume provides an acceptable level of quality and integrity. In addition to the volumetric examination with limited scan, Duke Energy performed a surface examination (code required) on the B09.011 item and achieved 100% coverage. The result from the surface examination was acceptable.

Duke Energy Corporation does not claim credit for coverage of the far side of austenitic piping welds. The characteristics of austenitic weld metal attenuate and distort the sound beam when shear waves pass through the weld metal. 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 single sided austenitic piping welds.

Although the procedures, personnel and equipment were qualified through PDI using longitudinal and shear waves search units and cracks were detected through the weld metal, PDI does not provide a qualification for single sided examination similar metal austenitic piping welds.

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 the weld, it would be detected and isolated. Specifically, leakage from the weld would be detected by monitoring of the Reactor Coolant System (RCS), which is performed once each shift under station procedure PTl1,2,3/A/0600110, "RCS Leakage". This RCS leakage monitoring is a requirement of Technical Specification 3.4.13, "Reactor Coolant System Leakage". Any discovered 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. 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 M:

Ultrasonic examination of the weld for item number C05.021 was 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 Performance Demonstration Initiative (PDI). 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. In addition to the volumetric examination with limited coverage, Duke Energy performed a surface examination (code required) on the C05.021 item and achieved 100% coverage. The result from the surface examination was acceptable.

Duke Energy Corporation does not claim credit for coverage of the far side of austenitic piping welds. The characteristics of austenitic weld metal attenuate and distort the sound beam when shear waves pass through the weld metal. 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 single sided austenitic piping welds.

Relief Request 04-ON-004 Page 8 of 8 Although the procedures, personnel and equipment were qualified through PDI using longitudinal and shear waves search units and cracks were detected through the weld metal, PDI does not provide a qualification for single sided examination similar metal austenitic piping welds.

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 the weld, it would be detected and isolated. One is that leakage from these welds would be detected by Operations personnel during their regular rounds (reference station procedure OP/3/A/1 1021020A. 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 item is 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 weld/component referenced in this request to the maximum extent possible utilizing the latest in examination techniques and equipment. The weld/component identified in Section I of this request 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 exams and surface exams this outage and the additional and pressure testing (VT-2) exams, it is Duke's belief that this combination of examinations provides a reasonable assurance of component integrity.

VII. Implementation Schedule Paragraph N:

The scheduled third 10-year interval plan code examination was performed on the referenced area/weld resulting in limited scan and volumetric coverage. No additional examinations are planned for the area/weld during the current inspection interval. The same area/weld 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.
