Subject:

Duke Energy Oconee Nuclear Station, Unit 1 Docket Nos. 50-269 Third Ten Year Inservice Inspection Interval Request for Relief No.02-005 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). This request is to allow Duke Energy to take credit for seventeen (17) limited ultrasonic examinations on welds described in the attached request.

During examination of the subject Unit 1 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).

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

Very truly yours, W. R. McCollum,<f Site Vice Pre dent Attachment

Relief Request 02-005 Page 4 of 7 IV. Basis for Relief Paragraph A:

During the ultrasonic examination of welds 1-SGA-WG25 & 1-SGB-WG25 and the Inside Radius Sections for both nozzles, 100% coverage of the required examination volume could not be obtained. The examination coverage was limited to 57.98% and 70.21%, respectively. Limitations are caused by the nozzle configuration. The percentage of coverage reported represents the aggregate coverage. In order to achieve more coverage the nozzle would have to be re-designed to allow scanning from both sides of the weld, which is impractical.

Paragraph B:

During the ultrasonic examination of welds 1-LDCB-IN-V1 and 1-LDCB-OUT-V2, 100% coverage of the required examination volume could not be obtained. The examination coverage was limited to 27.48%. Limitations are caused by the branch-weld configuration. The percentage of coverage reported represents the aggregate coverage. In order to achieve more coverage the nozzle would have to be re-designed to allow scanning from both sides of the weld, which is impractical.

Paragraph C:

During the ultrasonic examination of 1-RPV-LIGAMENTS, 100% coverage of the required examination volume could not be obtained. The examination coverage was limited to 84.52%. Limitations are caused by the clad area at each stud hole that causes the search unit to lift off the scanning surface. The percentage of coverage reported represents the aggregate coverage. In order to achieve more coverage the flange would have to be re-designed to allow for scanning, which is impractical.

Paragraph D:

During the ultrasonic examination of welds ILP-128-80, 1-51A-01-91A, IHP-324-118B, 1-51A-01-32AA, IHP 393-127A, 1-51A-02-34B, IHP-193-12, and 1-51A-01-103A, 100% coverage of the required examination volume could not be obtained. The examination coverage was limited to 59.74%, 60.84%, 61.54%, 60.39%, 59.3 1%,

61.3%, 59.37%, and 60.71%, respectively. Limitations are caused by the single sided access due to the valve configuration. The percentage of coverage reported represents the aggregate coverage. In order to achieve more coverage the valve configuration would have to be re-designed to allow scanning from both sides of the weld, which is impractical.

Paragraph E:

During the ultrasonic examination of weld 1HP-192-15, 100% coverage of the required examination volume could not be obtained. The examination coverage was limited to 60.99%. Limitations are caused by the flange configuration. In order to achieve more coverage the flange configuration would have to be re-designed to allow scanning from both sides of the weld, which is impractical.

Paragraph F:

During the ultrasonic examination of weld 1HP-70-1 1, 100% coverage of the required examination volume could not be obtained. The examination coverage was limited to 56.22%. Limitations are caused by the expansion joint configuration, which prevents access to both sides of the weld. In order to achieve more coverage the expansion joint configuration would have to be re-designed, which is impractical.

V. Alternate Examinations or Testin2 Paragraph G:

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. No additional examinations are planned for the area/weld during the current inspection interval.

Relief Request 02-005 Page 5 of 7 VI. Justification for Relief Paragraph H:

Ultrasonic examination of welds for item number B03.130 were conducted using personnel, equipment and procedures qualified in accordance with ASME Section XI, Appendix VIII, Supplements 4 and 6 of the 1995 Edition with the 1996 Addenda as administered through the Performance Demonstration Initiative (PDI) Program. 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 J for additional justification.)

Paragraph I:

Ultrasonic examination of welds for item numbers B03.140, B03.150 and B06.040 were conducted in accordance with ASME Section XI, Appendix I, 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 J for additional justification.)

Paragraph J:

Duke Energy will use pressure testing and VT-2 visual examination to compliment the limited examination coverage.

The Code requires (reference Table IWB-2500-1, item numbers B 15.050, B 15.030 and item number B 15.040) that a system leakage test be performed after each refueling outage for Class 1. Additionally a system hydrostatic test (reference Table IWB-2500-1, item numbers B 15.05 1, B 15.031 and item number B 15.04 1) is required once during each 10-year inspection interval. These tests require a VT-2 visual examination for evidence of leakage. This testing will provide 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 case that leakage did occur through these areas/welds, it would be detected and isolated. Specifically, leakage from these areas/welds would be detected by monitoring of the Reactor Coolant System (RCS), which is performed once each shift under procedure PT/1,2,3/A/0600/10, "RCS Leakage". This RCS leakage monitoring is a requirement of the Technical Specification 3.4.13, "Reactor Coolant System Leakage". Leakage is also evaluated in accordance with this Technical Specification. The leakage could be detected through several 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. This will provide reasonable assurance of weld/component integrity.

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 I 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 this outage, the additional pressure testing (VT-2) exams, and the various methods for leakage detection, it's our opinion that this combination of examinations provides a reasonable assurance of component integrity. Thus, an acceptable level of quality and safety will have been achieved and allowing relief from the aforementioned Code requirements will not endanger public health and safety.

Paragraph K:

Although the examination volume for C05.011 and C05.021 items as defined in ASME Section XI 1989 Edition with no addenda, Figure IWC-2500-7(a) could not be covered, the amount of coverage obtained for this examination provides an acceptable level of quality and integrity. This weld was examined using procedures, personnel and equipment qualified through the Performance Demonstration Initiative (PDI). In addition, this weld was examined during installation using volumetric and surface NDE methods.

Relief Request 02-005 Page 6 of 7 Current ultrasonic technology is not capable of consistently detecting and sizing flaws on the far side of an austenitic weld for configurations common to U.S. nuclear applications. To demonstrate that the best available technology was applied, PDI provides a best effort qualification instead of a complete single side demonstration. PDI Performance Demonstration Qualification Summary (PDQS) for austenitic piping shows that single sided examination is performed as a best effort. Therefore, the far side of the austenitic weld, which can only be accessed from one side, will be listed as an area of no coverage.

Duke Energy will use pressure testing and VT-2 visual examination to compliment the limited examination coverage.

The Code requires (reference IWC-2500-1, Item Numbers C07.030) that a functional/system inservice test once each period for Class 2 items. Additionally a system hydrostatic test (reference Table IWC-2500-1, Item Number C07.40) is required once during each 10-year inspection interval. These tests require a VT-2 visual examination for evidence of leakage. This testing will provide 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 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 OP/I/Ai 102/020. 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. All C05.011 and C05.021 items in this request are located in an area where operations personnel will be walking through as part of their rounds, with the exception of item number C05.021.078; therefore, any leak would be identified by visual observation. A second is that air monitors in the exhaust stacks. A third is that if a specific sump has to be pumped frequently would indicate leakage. All of these together will provide reasonable assurance of weld/component integrity.

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 I 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 this outage and the additional pressure testing (VT-2) exams, it's our opinion that this combination of examinations provides a reasonable assurance of component integrity. Thus, an acceptable level of quality and safety will have been achieved and allowing relief from the aforementioned Code requirements will not endanger public health and safety.

VII. Implementation Schedule Paragraph L The scheduled third 10-year interval plan code examination was performed on the referenced area/weld resulting in limited 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.
