== Description:== Limited Volumetric Examination Coverage Component Number: See Table 1 for a List of Component IDs 2.0 APPLICABLE CODE EDITION AND ADDENDA: The McGuire Nuclear Station (MNS), Unit 1 Fourth Inservice Inspection Interval is based on the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code, Section XI, 2007 Edition through the 2008 Addenda. MNS, Unit 1 maintains the responsibility to ensure exams were performed in accordance with the requirements of ASME, Section XI, Appendix VIII, Performance Demonstration for Ultrasonic Examination Systems, as amended and mandated by 10 CFR 50.55a. In the case of limited examinations, efforts were made to obtain additional examination coverage. Table 1 identifies if the examinations were performed in accordance with the requirements of ASME, Section XI, Appendix VIII. 3.0 APPLICABLE CODE REQUIREMENTS: 3.1. ASME Section XI Examination Category B-A The extent of examination requirement for Examination Category B-A, Item Number B1.11, per Table IWB-2500-1, requires a volumetric examination of all Circumferential Shell Welds, as shown in Figure IWB-2500-1. The extent of examination requirement for Examination Category B-A, Item number B1.12, per Table IWB-2500-1, requires a volumetric examination of all Longitudinal Shell Welds as shown in Figure IWB-2500-2. 3.2. ASME Section XI Examination Category B-D The extent of examination requirement for Examination Category B-D, Item Number B B3.110, per Table IWB-2500-1, requires a volumetric examination of all Pressurizer Nozzle-to-Vessel welds as shown in Figure IWB-2500-7(b).

McGuire Nuclear Station, Unit 1 Relief Request # RA-22-0024 Page 2 of 6 3.3. ASME Section XI Examination Method IWA-2200(c) In accordance with ASME Section XI, IWA-2200(c), all nondestructive examinations of the required examination surface or volume shall be conducted to the maximum extent practical. When performing VT-1, surface, radiographic, or ultrasonic examination on a component with defined surface or volume, essentially 100% of the required surface or volume shall be examined. Essentially 100% coverage is achieved when the applicable examination coverage is greater than 90%; however, in no case shall the examination be terminated when greater than 90% coverage is achieved, if additional coverage of the required examination surface or volume is practical. 4.0 IMPRACTICALITY OF COMPLIANCE: Pursuant to 10 CFR 50.55a(g)(5)(iii), relief is requested on the basis that conformance with these ASME Section XI Code requirements is impractical as conformance would require extensive structural modifications to the component or surrounding structure. 10 CFR 50.55a recognizes the limitations to Inservice Inspection of components in accordance with the ASME Section XI Code that are imposed due to early plants' design and construction. A design modification would be required to obtain ASME Code-required coverage. Therefore, it is impractical for MNS Unit 1 to satisfy the ASME Section XI code requirements to perform a volumetric examination of the components listed in Table 1 due to the physical component configuration, single sided access, and interference from permanent plant equipment. Table 1 provides a summary of the examination limitations for each component for which relief is requested. Table 1 also indicates the outage the component was examined, the coverage percentage obtained for each component, and other pertinent design information. This table is the cumulative list of the limited ASME Section XI examinations performed during the fourth ISI interval. Enclosure 2 provides non-destructive examination (NDE) data and coverage plots that detail the examination limitations. Accordingly, pursuant to 10 CFR 50.55a(g)(5)(iii), Duke Energy has determined that conformance with the code requirement of essentially 100% coverage of weld volume or area examined was impractical due to various constraints and limitations as stated above. Duke Energy requests NRC approval of the proposed alternative as stated below. 5.0 BURDEN CAUSED BY COMPLIANCE: Compliance with the applicable ASME Section XI Code volumetric examination requirements can only be accomplished by redesigning and refabricating the subject and/or surrounding components. Based on this, the ASME Section XI Code requirements are deemed impractical in accordance with 10 CFR 50.55a(g)(5)(iii).

McGuire Nuclear Station, Unit 1 Relief Request # RA-22-0024 Page 3 of 6 6.0 PROPOSED ALTERNATIVE AND BASIS FOR USE: On the basis that obtaining the required examination coverage is impractical due to physical obstructions and limitations imposed by original plant design and fabrication, no alternative examination for additional ultrasonic testing (UT) examination coverage is proposed. Radiography (RT) is not a desired option because it is limited in its ability to detect service-induced flaws. Use of other manual or automated UT techniques, whether conventional or phased array, were considered, but would not increase coverage due to limitation created by the component configuration. Based on the volumetric coverage obtained, along with the completed ASME Code required surface examination and System Pressure Tests, it is reasonable to conclude that if significant service induced degradation were occurring, it would have been evident by the examinations and testing that were performed. Duke Energy has determined that volumetric examinations performed to the extent practical provide reasonable assurance of structural integrity of the subject welds. 6.1. Examination Category B-A MNS Unit 1 has performed the ASME Section XI Code required examinations to the maximum extent practical (Code Coverage), which are documented in Table 1. In most exams, examination was limited due to the location of Core Stop Lugs below the welds consistent with previous exams. One examination was limited due to interference of the outlet nozzle boss, also consistent with previous exams. Due to the design of the reactor vessel and location of the Core Stop Lugs and Outlet Nozzle Boss causing these limitations, there are no alternative examination techniques currently available to increase coverage. In addition, VT-2 visual examinations associated with the Class 1 leakage test are performed each refueling outage. The volume of coverage obtained during the UT examinations along with ongoing leakage tests every refueling outage provide reasonable assurance that any flaw(s) that might have propagated through the subject welds are identified and dispositioned through the corrective action program. Additionally, any flaw(s) detected were evaluated as acceptable per Enclosure 2. Thus, Duke believes the completed exams provide an acceptable level of quality and safety.

McGuire Nuclear Station, Unit 1 Relief Request # RA-22-0024 Page 4 of 6 6.2. Examination Category B-D MNS Unit 1 has performed the ASME Section XI Code required examinations to the maximum extent practical (Code Coverage), which are documented in Table 1. The design of the pressurizer includes heater wells, which limit the available scanning area and nozzle geometry to single-sided access. This is consistent with previous exams. There are no alternative examination techniques currently available to increase coverage. In addition, VT-2 visual examinations associated with the Class 1 leakage test are performed each refueling outage. The volume of coverage obtained during the UT examinations along with ongoing leakage tests every refueling outage provide adequate assurance that any flaw(s) that might have propagated through the subject welds are identified and dispositioned through the corrective action program. Additionally, any flaw(s) detected were evaluated as acceptable per Enclosure 2. Thus, Duke believes the completed exams provide an acceptable level of quality and safety. 7.0 DURATION OF PROPOSED ALTERNATIVE: This request is proposed for the MNS Unit 1, 4th Inservice Inspection Intervals identified below: MNS Unit 1, Fourth Inservice Inspection Interval: Start Date: December 1, 2011 End Date: November 30, 2021

(Enclosure 2, Pg. Nos. 40 - 54) NOTES:

1. The following systems and their abbreviations are listed here:
a. Reactor Pressure Vessel (RPV)
b. Pressurizer (PZR)
2. The circumferential welds and longitudinal welds were examined from four orthogonal beam directions to the maximum extent practical in accordance with the criteria defined in 10 CFR 50.55a(b)(2)(xv)(G) and the minimum coverage requirements defined in 10 CFR 50.55a(b)(2)(xv)(K). In those areas where there are no obstructions to limit probe(s) movement, all four directions of data are reviewed for both Zone 1 and Zone 2. Zone 1 is defined as the inner 15% of the vessel wall thickness, measured from the clad to base material interface. Zone 2 is defined as the outer 85% of the vessel wall thickness. Thus, Zone 2 begins at the end of Zone 1 and extends to 100% of the component wall thickness. If there is an obstruction that limits one direction of movement, the opposing direction (non-limited) can be used to claim full coverage. This is allowed because the vendors demonstration utilized signal side access.

However, this single sided coverage is utilized only for Zone 2 (outer 85%t); Zone 1 (inner 15%t) is required to be covered from four orthogonal directions.
