ENCLOSURE TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT (BFN) UNIT 3 AMERICAN SOCIETY OF MECHANICAL ENGINEERS (ASME) SECTION XI, INSERVICE INSPECTION (ISI) PROGRAM (SECOND TEN-YEAR INSPECTION INTERVAL) REQUEST FOR RELIEF 3-ISI-7, REVISION 2 (SEE ATTACHED)
ENCLOSURE TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT (BFN) UNIT 3 AMERICAN SOCIETY OF MECHANICAL ENGINEERS (ASME) SECTION XI, INSERVICE INSPECTION (ISI) PROGRAM (SECOND TEN-YEAR INSPECTION INTERVAL) REQUEST FOR RELIEF 3-ISI-7, REVISION 2 Executive Summary : This request for relief addresses seven (7) Reactor Pressure Vessel (RPV) nozzle-to-vessel full penetration welds. The design configuration of the RPV nozzle-to-vessel and inner-radius welds precludes a 100 percent ultrasonic (UT) examination of the required volume for the full penetration welds of the nozzles listed in Table 1. These examination limitations occur when the ASME Section XI, 1989 Edition, no addenda, examination requirements are applied in areas of components constructed and fabricated to early plant designs. Based on a construction permit date prior to January 1, 1971, BFN is exempt from meeting certain provisions of the Code requirements for examination access, to the extent practical, within the limitations of design, geometry, and materials of construction of the components in accordance with 10 CFR 50.55a(g) (4). A UT examination was performed on accessible areas to the maximum extent practical given the physical limitations of the subject welds. The subject welds were examined with the latest ultrasonic techniques, procedures, equipment, and personnel qualified to the requirements of the Performance Demonstration Initiative (PDI) Program, as mandated by 10 CFR 50.55a(g) (4). The design configuration limits UT examination of the RPV nozzle-to-vessel weld coverage (percentage) to that shown in Table 1. TVA concludes that performance of an UT examination of essentially 100 percent of the RPV nozzle-to-vessel full penetration welds would be impractical. The performance of the UT examination of the subject areas to E-2
the maximum extent practical provides an acceptable level of quality and safety because the information and data obtained from the volume examined provides sufficient information to judge the overall integrity of the welds. Therefore, pursuant to 10 CFR 50.55a(g) (5) (iii), it is requested that relief be granted for the second inspection interval. On February 20, 2004, TVA requested NRC approval to utilize Subarticle IWA-2430 of the 1995 Edition through 1996 Addenda of the ASME Section XI, Division 1 Code. NRC approved this request by letter dated March 29, 2004. This Edition of the Code allowed TVA to extend the BFN Unit 3 Second Ten-Year ISI Interval for up to one year (for the seven components referenced above) without delaying the start of the Unit 3 Third Ten-Year ISI Inspection Interval on November 19, 2005. TVA examined the seven RPV nozzle-to-vessel welds during the Cycle 12 refueling outage (Spring 2006). Therefore, since the seven (7) RPV Nozzle examinations are for the Unit 3 Second Ten-Year Interval, the Code of Record is the 1989 Edition, No addenda of the ASME Section XI, Division 1 Code and the Code of Record for NDE is the 1995 Edition through the 1996 Addenda of the ASME Section XI, Division 1 Code. The seven (7) RPV Nozzles are as follows: N2G, N2H, N2J, N2K, N3C, N3D, and N8B. Unit: Three (3) System: Reactor Pressure Vessel (RPV), System 329 Components: Seven (7) RPV Nozzles full penetration welds as listed in Table 1 ASME Code Class: ASME Code Class 1 (Equivalent) Section XI Edition: 1989 Edition, no addenda Code Table: IWB-2500-1 E-3
Examination Category: B-D, Full Penetration Welds of Nozzles in Vessels Examination Item Number: B3.90, Reactor Vessel Nozzle-to-Vessel Welds Code Requirement: ASME Section XI, Table IWB-2500-1, Examination Category B-D, Item No. B3.90 requires a volumetric examination of essentially 100 percent of the weld and adjacent base material as depicted in Figure IWB-2500-7(a). Code Requirements From Which Relief Is Requested: Relief is requested from the requirement of ASME Section XI Code, Table IWB-2500-1, Examination Category B-D, Item No. B3.90 to perform essentially 100 percent volumetric examination of weld and adjacent base material. List Of Items Associated With The Relief Request: N2G RPV Nozzle-to-Vessel Weld N2H RPV Nozzle-to-Vessel Weld N2J RPV Nozzle-to-Vessel Weld N2K RPV Vessel-to-Nozzle Weld N3C RPV Nozzle-to-Vessel Weld N3D RPV Nozzle-to-Vessel Weld N8B RPV Nozzle-to-Vessel Weld Basis For Relief: The design configuration of the RPV nozzle-to-vessel welds precludes an UT examination of essentially 100 percent of the required volume. The component design configuration limits UT examination coverage of the welds to the percentages listed in Table 1. Alternative Examination: None. In lieu of the ASME Code require essentially 100 percent volume UT examination, TVA proposes a UT examination of accessible areas to the maximum extent practical given the component design configuration of the RPV nozzle-to-vessel welds. E-4
Justification for The Grantina of Relief: (1) The design configuration of the subject nozzle-to-vessel welds precludes UT examination of essentially 100 percent of the required examination volume. Access to the nozzle-to-vessel welds is by a series of doorways in the concrete biological shield wall. Insulation behind these doorways is designed for removal around the nozzle circumference. In order to examine the welds in accordance with the Code requirements the RPV would require extensive design modifications. The physical arrangement of the nozzle-to-vessel welds precludes UT examination from the nozzle side. The limitations are inherent to the barrel-type nozzle-to-vessel weld design and are compounded by the close proximity of the biological shield wall. Scanning from the nozzle surface is ineffective due to the weld location and the asymmetrical inside surface where the nozzle and vessel converge. Coverage was increased by scanning from the outside blend radius of the weld where practical. Experience from the automated UT examinations performed at other BWRs from the inside surface has shown that the nozzle-to-vessel weld coverage would not be greatly improved even if performed from the inside surface utilizing the current state-of-the-art techniques. The configuration of the nozzle-to-vessel welds precludes UT examination from the nozzle side due to the weld location and the asymmetrical inside surface where the nozzle and vessel converge. The extent of examination coverage from the vessel side provides reasonable assurance that no flaws oriented parallel to the weld are present. The areas receiving little or no examination coverage are located toward the outside surface of the reactor vessel in the general area of the nozzle outside blend radius. (The blend radius restricts the scanning movement and/or transducer contact.) The reactor vessel inner-half of the thickness and inside surface are interrogated with the UT beam. Degradation located at the inside surface or inner-half of the vessel would be located. E-5
The subject welds were examined with the latest ultrasonic techniques, procedures, equipment, and personnel qualified to the requirements of the Performance Demonstration Initiative (PDI) Program, in accordance with the requirements of the 1995 Edition, 1996 Addenda of ASME Section XI, Division 1, Appendix VIII, as mandated by 10 CFR 50.55a(g) (4). No recordable indications were identified in any of the seven nozzle examinations. (2) Radiographic examination as an alternate volumetric examination method was determined to be impractical due the radiological concerns. Gaining access to the inside surface of the RPV to place radiographic film would require extensive personnel protection due to high radiation and contamination levels. Also, due to the varying thickness at the outside blend radius of the weld several radiographs may be required of one area to obtain the required coverage and/or film density. The additional Code coverage gained by radiography is impractical when weighed against the radiological (i.e., dose) concerns. Therefore, TVA concludes that performing a UT examination of essentially 100 percent of the nozzle-to-vessel full penetration welds, would be impractical. Further, it would also be impractical to perform other volumetric examinations (i.e., radiography) which may increase examination coverage. A maximum extent practical UT examination of the subject areas provides an acceptable level of quality and safety. TVA concludes that significant degradation, if present, would be detected during a UT examination performed to the maximum extent practical of the subject welds. As a result, reasonable assurance of operational readiness of the subject welds has been provided. Therefore, pursuant to 10 CFR 50.55a (g) (5) (iii), TVA requests that relief be granted for the second ten-year inspection interval. E-6
Implementation Schedule: This request for relief is applicable to the second ten-year inspection interval for BFN Unit 3. The second ten-year inspection interval was extended in accordance with ASME Section XI, Subarticle IWA-2430 for the seven RPV nozzles.

This procedure has been demonstratedfor detection of flaws located throughout the entire weld thickness. Coverage obtained during axial scans is typically limited due to nozzle configuration. In the circumferentialscan direction the outer 85%-t is examined with the same vessel procedureas above and typically limited due to nozzle configuration. To achieve additionalcoverage in the circumferential sca n direction a second examination is performed with a proceduredemonstratedfor nozzle inside-radius UT.

Manual ultrasonic examinations were performed on the referenced weld during Browns Ferry Unit 3 U3C1 2. In accordance with UT Procedure N-UT-78-03, 600 Longitudinal wave examinations were performed from the vessel surface in both the radial and circumferential scan directions. These examinations resulted in no reportable indications. l SInaccordance with UT Procedure 54-1SI-850-03 and the referenced TVAIEPRI modeling the following additional examinations were performed. These examinations also resulted In no reportable indications. Recirculation Inlet (N2) Nozzle Modeling Parameters Probe Probe Skew Scan Surface 600 Shear +(36 to 66) Vessel 400 Shear *120 Blend 42% coverage of the required examination volume was obtained. Note: Refer to the nozzle coverage sketch for a description of the scanning volume, examination coverage and scan limitations. Note 1: This ultrasonic examination was performed in accordance with the criteria of 10CFR 50.55a (b) (2) (xv) (G) and the minimum coverage requirements of 10CFR 50.55a (b) (2) (xv) (K) was achieved to the maximum extent possible. Radial examinations of the outer 85%t were limited to 51.39% volumetric coverage due to nozzle blend radius interference. Note 2: See TVA Request for Relief PDI-1 and PDI-2. Dockets No. 50-2611296; 50-3271328; and 50-0390. This relief request changed the area to be examined per IWB-2500-7 (a) and (b) to the weld plus a 'A"on each side. This examination satisfies the requirements of ASME Sec. XI (1989 Edition no Addenda), Category B-D, for item number B3.90, figure number IWB 2500-7(a) exam volume, and was performed using ASME Sec XI, Appendix VIII qualified personnel, procedures, and equipment as amended by the Final Rule.

A RPV Nozzle-To-Shell Weld AR EVA Ultrasonic Examination Limitation and Coverage Worksheet Axial scans are performed with a procedurefor the examination of vessel shell welds. This procedurehas been demonstrated for detection of flaws located throughout the entire weld thickness. Coverage obtained during axial scans is typically limited due to Anozzle configuration. In the circumferentialscan direction the outer 85%-t is examined with the same vessel procedure as above and typically limited due to nozzle configuration. To achieve additionalcoveragein the circumferentialscan directiona second examination is performed with a proceduredemonstratedfor nozzle inside-radius UT. This procedurehas been demonstratedfor detection of flaws in the inner 15%-t only. The nozzle inside-radius technique provides additional coverage since the component is modeled and scanning is performed with several search units from the nozzle blend. A0,01.Sin . _1 p,7 . .. ., .'

The tangential scans were performed with +10° skew towards the weld and at varying distances from the weld. Circumferential scans with a second procedure were also performed from the blend radius. This technique has been demonstrated for detection of axial flaws in the inner 15%-t only. These scans achieved 100% circumferential coverage of the inner 15%-t. 100% of accessible surface was scanned resulting in 42% coverage. N2 Nozze-to-Shell CD

RPV Nozzle-To-Shell Weld Ultrasonic Examination Limitation and Coverage Worksheet Utility: TVA Plant: BFN3 Unit: 3 Weld ID: N2J Date: 03118/06 Summary No: U3C12-N2J-NV Axial scans are performed with a procedure for the examination of vessel shell welds. This procedurehas been demonstrated for detection of flaws located throughoutthe entire weld thickness. Coverage obtained during axial scans is typically limited due to nozzle configuration. In the circumferentialscan direction the outer 85%-t is examined with the same vessel procedure as above and typically limited due to nozzle configuration. To achieve additionalcoverage in the circumferentialscan direction a second examination is performed with a proceduredemonstratedfor nozzle inside-radius UT. This procedurehas been demonstratedfor detection of flaws in the inner 15%-t only. The nozzle inside-radius technique provides additionalcoverage since the component is modeled and scanning is performed with several search units from the nozzle blend.

A RPV Nozzle-To-Shell Weld Ultrasonic Examination Limitation and Coverage Worksheet AR EVA Tangential and radial scans are limited due to liftoff caused by the blend radius and transducer footprint. 60ORL radial and tangential scans were performed from the shell surface. The tangential scans were performed with +/-100 skew towards the weld and at varying distances from the weld. Circumferential scans with a second procedure were also performed from the blend radius. This technique has been demonstrated for detection of axial flaws in the inner 15%-t only. These scans achieved 100% circumferential coverage of the inner 15%-t 100% of accessible surface was scanned resulting in 42% coverage. IL --. --- -- - _ J_ _ .

Note: Refer to the nozzle coverage sketch for a description of the scanning volume, examination coverage and scan limitations. Note 1: This ultrasonic examination was performed in accordance with the criteria of 10CFR 50.55a (b) (2) (xv) (G) and the minimum coverage requirements of 10CFR 50.55a (b) (2) (xv) (K)was achieved to the maximum extent possible. Radial examinations of the outer 85%t were limited to 51.39% volumetric coverage due to nozzle blend radius interference. Note 2: See TVA Request for Relief PDI-1 and PDI-2. Dockets No. 50-2611296; 50-327/328- and 50-0390. This relief request changed the area to be examined per IWB-2500-7 (a) and (b) to the weld plus a 1/2'" on each side. This examination satisfies the requirements of ASME Sec. XI (1989 Edition no Addenda), Category B-D, for item number B3.90, figure number IWB 2500-7(a) exam volume, and was performed using ASME Sec X1, Appendix ViII qualified personnel, procedures, and equipment as amended by the Final Rule.

This procedurehas been demonstratedfor detection of flaws located throughout the entire weld thickness. Coverage obtainedduring axial scans is typically limited due to nozzle configuration. In the circumferentialscan direction the outer 85%-t is examined with the same vessel procedureas above and typically fimited due to nozzle configuration. To achieve additional coverage in the circumferentialscan direction a second examination is performed with a proceduredemonstratedfor nozzle inside-radius UT. This procedure has been demonstrated for detection of flaws in the inner 15%-I only. The nozzle inside-radius technique provides additionalcoverage since the component is modeled and scanning is performed with severalsearch units from the nozzle blend. AalSanis CircumfietaSan

The tangential scans were performed with :1:10° skew towards the weld and at varying distances from the weld. Circumferential scans with a second procedure were also performed from the blend radius. This technique has been demonstrated for detection of axial flaws in the inner 15%-t only. These scans achieved 100% circumferential coverage of the inner 15%-t. 100% of accessible surface was scanned resulting in 42% coverage. 519057800 etin5 aIPge5of1 N2 Noule4o-She~ll

Note: Refer to the nozzle coverage sketch for a description of the scanning volume, examination coverage and scan limitations. Note 1: This ultrasonic examination was performed in accordance with the criteria of IOCFR 50.55a (b) (2) (xv) (G) and the minimum coverage requirements of 10CFR 50.55a (b) (2) (xv) (K)was achieved to the maximum extent possible. Radial examinations of the outer 85%t were limited to 35.22% volumetric coverage due to nozzle blend radius interference. Note 2: See TVA Request for Relief PDI-1 and PDI-2. Dockets No. 50-261/296; 50-327/328; and 50-0390. This relief request changed the area to be examined per IWB-2500-7 (a) and (b) to the weld plus a 'A' on each side. This examination satisfies the requirements of ASME Sec. Xi (1989 Edition no Addenda), Category B-D, for item number B3.90, figure number IWB 2500-7(a) exam volume, and was performed using ASME Sec XI, Appendix VIII qualified personnel, procedures, and equipment as amended by the Final Rule.

This procedure has been demonstratedfor detection of flaws located throughoutthe entire weld thickness. Coverage obtained during axial scans is typically limited due to nozzle configuration. In the circumferentialscan direction the outer 85%-t is examined with the same vessel procedureas above and typically limited due to nozzle configuration. To achieve additionalcoverage in the circumferentialscan direction a second examination is performed with a procedure demonstrated for nozzle inside-radius UT. This procedure has been demonstratedfor detection of flaws in the inner 15%-t only. The nozzle inside-radius technique provides additionalcoverage since the component is modeled and scanning is performed with several search units from the nozzle blend.

The tangential scans were performed with 110* skew towards the weld and at varying distances from the weld. Circumferential scans with a second procedure were also performed from the blend radius. This technique has been demonstrated for detection of axial flaws in the inner 15%-t only. These scans achieved 100% circumferential coverage of the inner 15%-t. 100% of accessible surface was scanned resulting in 36% coverage. /- I-M3 Nonzze-lo-S1eWl 90-9015478-000 Section 5 Tab K Page 5 of 10

This procedure has been demonstrated for detection of flaws located throughout the entire weld thickness. Coverage obtained dunng axial scans is typically limited due to nozzle configuration. In the circumferentialscan direction the outer 85%-4 is examined with the same vessel procedureas above and typically limited due to nozzle configuration. To achieve additionalcoveragein the circumferentialscan direction a second examination is performed with a proceduredemonstrated for nozzle inside-radius UT. This procedurehas been demonstratedfor detection of flaws in the inner 15%4 only. The nozzle inside-radius technique provides additionalcoverage since the component is modeled and scanning is performed with several search units from the nozzle blend.

The tangential scans were performed with 1-10 skew towards the weld and at varying distances from the weld. Circumferential scans with a second procedure were also performed from the blend radius. This technique has been demonstrated for detection of axial laws in the inner 155%-t only. These scans achieved 100% circumferential coverage of the inner 15%-t 100% of accessible surface was scanned resulting in 36% coverage. N3 Ntieo4o-He

In accordance with UT Procedure N-UT-78-03, 60° Longitudinal wave examinations were performed ftrom the vessel 4 surface in both the radial and circumferential scan directions. These examinations resulted in no reportable indications. In accordance with UT Procedure 54-ISI-850-03 and the referenced TVA/EPRI modeling the following additional examinations were performed. These examinations also resulted in no reportable indications. Jet Pump Instrumentation (N8) Nozzle Modeling Parameters Probe Probe Skew I Scan Surface 500 Shear *(15 to 45) Vessel 64% coverage of the required examination volume was obtained. Note: Refer to the nozzle coverage sketch for a description of the scanning volumie, examination coverage and scan limitations. Note 1: This ultrasonic examination was performed in accordance with the criteria of IOCFR 50.55a (b) (2) (xv) (G) and the minimum coverage requirements of 10CFR 50.55a (b) (2) (xv) (K)was achieved to the maximum extent possible. Radial examinations of the outer 85%t were limited to 69.92% volumetric coverage due to nozzle blend radius interference. Note 2: See TVA Request for Relief PDI-1 and PDI-2. Dockets No. 50-261/296; 50-3271328; and 50-0390. This relief request changed the area to be examined per IWB-2500-7 (a) and (b) to the weld plus a '" on each side. This examination satisfies the requirements of ASME Sec. XI (1989 Edition no Addenda), Category B-D, for item number B3.90, figure number IWB 2500-7(a) exam volume, and was performed using ASME Sec XI, Appendix VIII qualified personnel, procedures, and equipment as amended by the Final Rule.

A RPV Nozzle-To-Shell Weld A REVA Ultrasonic Examination Limitation and Courage Worksheet Utility: TVA EWed Plant:BFN3 Unit: 3 ID: NOB Date: 0318/06 1Summary N2: U3Cl2-NBV Axial scans are performed with a procedurefor the examination of vessel shell welds. This procedure has been demonstratedfor detection of flaws located throughoutthe entire weld thickness. Coverage obtained during axial scans is typically limited due to nozzle configuration. In the circumferential scan direction the outer85%-4 is examined with the same vessel procedureas above and typically limited due to nozzle configuration. To achieve additionalcoverage in the circumferentialscan direction a second examinationis performed with a proceduredemonstrated for nozzle inside-radius UT. This procedurehas been demonstratedfor detection of flaws in the inner 15%4t only. The nozzle inside-radus technique provides additionalcoverage since the component is modeled and scanning is performedwith several searchunits from the nozzle blend.

A RPV Nozzle-To-Shell Weld Ultrasonic Examination Limitation and Courage Worksheet AREVA Tangential and radial scans are limited due to liftoff caused by the blend radius and transducer footprint. N8 Nozzle to Shell 60°RL radial and tangential scans were performed from the shell surface. -Tangential (Circumferential) Scan
- Radial (Axial) Scan The tangential scans were performed with +10* skew towards the weld and at varying distances from the weld.
Circumferential scans with a second procedure were also performed from the vessel shell at various skews. This technique has been demonstrated for detection of axial flaws in the inner 155%-t only. These scans achieved 100% circumferential coverage of the inner 15%4. 100% of accessible surface was scanned resulting in 64% coverage. l °l
