In the Matter of Tennessee Valley Authority))Docket No. 50-296 BROWNS FERRY NUCLEAR PLANT (BFN) -UNIT 3 -AMERICAN SOCIETY OF MECHANICAL ENGINEERS (ASME) SECTION XI, INSERVICE INSPECTION (ISI) PROGRAM, THIRD TEN-YEAR INSPECTION INTERVAL -REQUESTS FOR RELIEF 3-ISI-22 AND 3-ISI-23 In accordance with 10 CFR 50.55a(g)

(5) TVA is requesting relief from certain inservice inspection requirements in Section XI of the ASME Boiler and Pressure Vessel Code. This letter submits BFN Unit 3 requests for relief 3-ISI-22, and 3-ISI-23.Request for relief 3-ISI-22, addresses one (1) Reactor Water Recirculation (RECIRC) system full penetration piping to valve weld. The design configuration of the component precludes a 100 percent ultrasonic (UT) examination of the required volume for the full penetration weld.Request for relief 3-ISI-23, addresses nine (9) Reactor Pressure Vessel (RPV) nozzle-to-vessel full penetration welds and seven (7) RPV nozzle inner radius sections.

The design configuration of the RPV nozzle-to-vessel welds precludes a 100 percent ultrasonic (UT) examination of the required volume for the full penetration welds of the nozzles. 7 7 U.S. Nuclear Regulatory Commission Page 3 August 24, 2007 Enclosures cc (Enclosures):

Previous ASME Section XI Code examinations of RECIRC weld GR-3-63 cited in request for relief 3-ISI-22 were performed prior to rulemaking for 10 CFR 50.55a(b)

(2) (xv) (A) (2).This weld received 100 percent Code coverage in accordance with earlier Code requirements and therefore, did not require a request for relief.Enclosure 2 contains request for relief 3-ISI-23.

Request for relief 3-ISI-23 is consistent with the BFN Unit 3 Second Ten-Year ISI inspection interval requests for relief 3-ISI-7, Revision 0, 3-ISI-14, and 3-ISI-15 by letters dated March 26, 1999, and May 9, 2003 respectively.

NRC approved these requests by letters dated August 2, 1999, and February 11, 2004.There are no new regulatory commitments in this letter. If you have any questions, please contact me at (256) 729-2636.D. T. Langley L Manager of Licensing and Industry Affairs cc: See Page 3 ENCLOSURE 1 TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT (BFN)UNIT 3 AMERICAN SOCIETY OF MECHANICAL ENGINEERS (ASME)SECTION XI, INSERVICE INSPECTION (ISI) PROGRAM (THIRD TEN-YEAR INSPECTION INTERVAL)REQUEST FOR RELIEF 3-ISI-22 (SEE ATTACHED)

TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT (BFN)UNIT 3 AMERICAN SOCIETY OF MECHANICAL ENGINEERS (ASME)SECTION XI,INSERVICE INSPECTION (ISI) PROGRAM (THIRD) TEN-YEAR INSPECTION INTERVAL)REQUEST FOR RELIEF 3-ISI-22 Executive Summary: This request for relief addresses one (1)Reactor Water Recirculation (RECIRC) System, Full Penetration Piping Weld examined in the first period (Cycle 12, Spring 2006) of the Third Ten-Year ISI inspection interval.The subject weld was examined with the latest ultrasonic (UT) 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) and 10 CFR 50.55a(g)

(6)(ii)(C).

A UT examination was performed on this piping weld of the accessible areas to the maximum extent practical.due to the component configuration.

Credit for the one-sided only ultrasonic examination provided 75 percent coverage due to the requirement mandated in 10 CFR 50.55a(b)

(2) (xv) (A) (2), which states,"Where examination from both sides is not possible on austenitic welds, full coverage credit from a single side may be claimed only after completing a successful single sided Appendix VIII demonstration using flaw on the opposite side of the weld." There is no Appendix VIII Program for cast austenitic piping welds. Therefore, only 75 percent coverage can be claimed for RECIRC System weld GR-3-63.The performance of the ultrasonic examination of the subject areas to the maximum extent practical provides an acceptable level of quality and safety since the data obtained from the volume examined provides sufficient information to judge the overall integrity of the piping welds. The examination limitation does not affect the sizing of the previously recorded indication.

List Of Items Associated With The Relief Request: Therefore, pursuant to 10 CFR 50.55a(g)

(5) (iii), TVA requests that relief be granted for the BFN Unit 3, Third Ten-Year ISI inspection interval.Three (3)Reactor Water Recirculation (RECIRC) System, System 068 1 (one) Full Penetration Piping to valve Weld (Austenitic Stainless Steel)ASME Code Class 1 2001 Edition, as amended by 10 CFR 50.55a(b)

(2) (xv) (A) (2) and 10 CFR 50.55a(b)

(2) (xxiv)Code Case N-577, N-577-2500, Table I R-A, Risk-Informed Piping Examinations R1.16, Elements Subject to Intergranular Stress Corrosion Cracking (IGSCC)Code Case N-577, N-577-2500, Table I, Examination Category R1.16, Requires Volumetric Examination of 100 percent of the Weld and Adjacent Base Material as depicted in Figure IWB-2500-8(c).

Relief is requested from the Risk-Informed Inservice Inspection Program, Code Case N-577 requirement (Table I, N-577-2500)

Examination Category R-A, Item No. R1.16)to perform essentially 100 percent volumetric examination of the weld and adjacent base material.RECIRC System, Weld GR-3-63, Valve to Pipe (28-inch NPS, Austenitic Stainless Steel)EI-3 Basis for Relief: It is not possible to perform the volumetric ultrasonic examination from both sides of the weld due to the configuration of the component.

Also, because of a recent requirement mandated by 10 CFR 50.55a(b)

(2) (xv) (A) (2)which states, "Where examination from both sides is not possible on austenitic welds, full coverage credit from a single side may be claimed only after completing a successful single sided Appendix VIII demonstration using flaw on the opposite side of the weld." Presently, there is no Appendix VIII Program for cast austenitic piping welds; therefore, only 75 percent coverage can be claimed.Under the previous ASME Section XI Code requirements

[i.e., prior to rulemaking that added 10 CFR 50.55a(b)

(2) (xv) (2)] UT coverage attained would have been 100 percent.The examination limitations for Weld GR-3-63 were due the configuration of the component, valve to pipe. The performance of the ultrasonic examination of the subject areas to the maximum extent practical provides an acceptable level of quality and safety since the data obtained from the volume examined provides sufficient information to judge the overall integrity of the piping welds. A detailed description of the UT examination limitations are provided in Table 1.None. In lieu of the Code required essentially 100 percent volume ultrasonic examination, TVA proposes an ultrasonic examination of accessible areas to the maximum extent practical given the component design configuration of the aforementioned valve to piping weld.The weld was 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 2001 Edition, as amended by 10 CFR 50.55a(b)

(2) (xv) (A) and 10 CFR 50.55a(b)

(2) (xxiv), of ASME Section XI, Division 1, Appendix VIII as mandated by Alternative Examination:

Justification For The Granting Of Relief: E1-4 10 CFR 50.55a(g)

(4) and 10 CFR 50.55a(g)

(6) (ii) (C).An ultrasonic examination was performed on the piping weld of the accessible areas to the maximum extent practical given the component configuration.

Credit for the one-sided only ultrasonic examination provided 75 percent coverage because of a requirement mandated in 10 CFR 50.55a(b)

(2) (xv) (2), which states, "Where examination from both sides is not possible on austenitic welds, full coverage credit from a single side may be claimed only after completing a successful single sided Appendix VIII demonstration using flaw on the opposite side of the weld." Currently, there is no Appendix VIII Program for cast austenitic piping welds; therefore, only 75 percent coverage can be claimed. Under the original ASME Section XI Code requirements UT coverage attained would have been 100 percent.The performance of the ultrasonic examination of the subject weld to the maximum extent practical provides an acceptable level of quality and safety because the information and data obtained from the volume examined is sufficient to judge the overall integrity of the piping welds. The examination limitation does not affect the sizing of the previously recorded indication.

Therefore, pursuant to 10 CFR 50.55a(g)

(5) (iii), TVA requests that relief be granted for the Third Ten-Year ISI inspection interval.Implementation Schedule:

This request for relief is applicable to the BFN Unit 3, Third Ten-Year ISI inspection interval (November 19, 2005 to November 18, 2015). The weld listed in Table 1 was examined during the first period (Cycle 12, i.e., Spring 2006) of the Third Ten-Year ISI inspection interval.Attachments:

Also, the limitation prevented scanning in both axial directions.

Circumferential scans were performed from both sides of the weld centerline.

Therefore, only 75 percent coverage can be claimed.E1-7 Attachment A One (1) Drawing Drawing 3-ISI-0328-C, Sheet 2 REFERENCE DRAWINGS: TVA 47KI544-3 GE f53F754 KELLGOG BF 2-180 NoTE: THIS DRAWING SUPERSEDES CNM-2139-C ALL SHEETS B -L OOP CR-J-59 GR-J-59-LS--

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, 2001 Edition, in accordance with 10 CFR 50.55a(b)

(2)(xxiv) and, as amended by Sections 10 CFR 50.55a(b)(2)(xv)(B) through 10 CFR 50.55a(b)

(2) (xv) (G), and 10 CFR 50.55a(b)

(2)(xvi)(A), 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 maximum 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) and.10 CFR 50.55a(g)

(6) (ii) (C). 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 E2-2 performance of the UT examination of the subject areas to the maximum extent practical provides an acceptable level of quality and safety since the 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), TVA requests that relief be granted for the BFN Unit 3, Third Ten-Year ISI inspection interval.The 2001 Edition, in accordance with 10 CFR 50.55a(b)

List Of Items Associated With The Relief Request: Relief is requested from the requirements 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 and Item No. B3.100 to perform essentially 100 percent volumetric examination of the nozzle inner radius section.NIA NIA N2B N2B N2D N2D N2F N2F N3B N3B N4B N4C N5A N5A N8A N8A RPV Nozzle-to-Vessel Weld RPV Inner Radius Section RPV Nozzle-to-Vessel Weld RPV Inner Radius Section RPV Nozzle-to-Vessel Weld RPV Inner Radius Section RPV Vessel-to-Nozzle Weld RPV Inner Radius Section RPV Nozzle-to-Vessel Weld RPV Inner Radius Section RPV Nozzle-to-Vessel Weld RPV Nozzle-to-Vessel Weld RPV Nozzle-to-Vessel Weld RPV Inner Radius Section RPV Nozzle-to-Vessel Weld RPV Inner Radius Section E2-4 Basis For Relief: The design configuration of the RPV nozzle-to-vessel welds precludes a UT examination of essentially 100 percent of the required volume. The component design configuration limits UT examination coverage of the welds to the percentages shown in Table 1.Visual examination of the inner radius section for the above nozzles is limited because the reactor internal piping configuration prevents placement of the camera in all positions necessary to examine the surface M-N [See Figures TWB-2500-7(a) through (d)] over the full circumference.

This prevents the examination from obtaining essentially 100 percent coverage.A detailed description of the examination limitations is provided below: " N1 nozzles (2), RECIRC Outlet and N3 nozzles (4), Main Steam Outlet There are no thermal sleeves or piping inside the nozzles, they are of sufficient size to perform visual examination on the majority of the nozzle bore region. However, to achieve enhanced visual examination criteria the underwater camera would need to be placed inside the nozzle opening and using conventional underwater camera and fixtures, it is not possible to maintain required camera angle to fully examine the inner most portion of the nozzle bore. Therefore, for the examination of the recirculation outlets (N1 nozzles) and the main steam (N3 nozzles), less than 100 percent examination volume was achieved.

The estimated examination coverage for these nozzles was 90 percent of the required volume." N2 nozzles (10), RECIRC Inlet Thermal Sleeve and Jet Pump Riser Piping The inaccessible area is the inside bend radius of elbow at approximate clock positions 11:00 to 1:00, and at the bottom outside diameter bend of the elbow at approximate clock positions 5:00 to 7:00. The limitations are due to the proximity of the of the jet pump risers.E2-5 0 N5A and N5B, Core Spray Nozzles Core spray thermal sleeve and tee box and feed water sparger. Feedwater spargers are located above the core spray nozzle and the configuration of the core spray thermal sleeve and tee box prohibits placement of the camera 360 degrees around the nozzle.The limitations are at the top position at approximate clock positions 10:00 to 2:00, and the bottom position at approximate clock positions 4:00 to 8:00.* NBA and N8B nozzles, RECIRC Instrumentation Twelve instrumentation lines pass through the vessel wall into the vessel. The core shroud support plate is located directly beneath the nozzle preventing placement of the camera from approximate clock positions 4:00 to 8:00.Alternative Examination:

In lieu of the Code requirement for essentially 100 percent volume UT examination on the nozzle to vessel weld, TVA proposes a UT examination of accessible areas to the maximum extent practical given the component design and configuration of the RPV nozzle-to-vessel welds.For the RPV inner radius section in accordance with Code Case N-648-1, in lieu of a UT examination, a visual examination with enhanced magnification that has a resolution sensitivity to detect a 1-mil width wire or crack, utilizing the allowable flaw length criteria of Table IWB-3512-1 with limiting assumptions on the flaw aspect ratio was performed.

The provisions of the 2001 Edition, in accordance with 10 CFR 50.55a(b)(2)(xxiv) and, as amended by Sections 10 CFR 50.55a(b)

(2)(xv)(B) through 10 CFR 50.55a(b)

(2)(xv)(G), and 10 CFR 50.55a(b)

(2)(xvi)(A), of Table IWB-2500-1, Examination Category B-D, continue to apply except that, in place of examination volumes, the surfaces to be examined are the external surfaces shown in the figures applicable to this table.E2-6 The estimated enhanced remote visual (VT-i)examination coverage achieved for each nozzle is provided in Table 1.Justification for The Granting 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 arrangements of the nozzle-to-vessel welds preclude 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 welds 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.E2-7 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.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 2001 Edition, in accordance with 10 CFR 50.55a(b)

(2)(xxiv) and, as amended by Sections 10 CFR 50.55a(b)(2)(xv)(B) through 10 CFR 50.55a(b)

(2)(xv)(G), and 10 CFR 50.55a(b)

(2)(xvi)(A), by following the Electric Power Research Institute's (EPRI) Performance Demonstration Initiative (PDI) processes.

(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 concerns.Therefore, TVA concludes that performing an UT examination of essentially 100 percent of the nozzle-to-vessel full penetration welds and a 100 percent enhanced remote Visual VT-i with 1-mil wire resolution on the inner radius section, 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 an 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.E2-8 Implementation Schedule: Accordingly, pursuant to 10 CFR 50.55a(g)

(5) (iii), TVA requests that relief be granted for the BFN Unit 3, Third Ten-Year ISI inspection interval.This request for relief is applicable to the BFN Unit 3, Third Ten-Year ISI inspection interval (November 19, 2005 to November 18, 2015). The nozzle-to-vessel welds listed in Table 1 were examined in the first period (Cycle 12, i.e., Spring 2006) of the Third Ten-Year inspection interval.Request for Relief 3-ISI-23 is consistent with BFN Unit 3 Second Ten-Year inspection interval requests for relief 3-ISI-7, Revision 0, 3-ISI-14, and 3-ISI-15 submitted by TVA letters dated March 26, 1999, and May 9, 2003 respectively.

NRC approved these requests by letters dated August 2, 1999, and February 11, 2004.TVAN Nondestructive Examination Procedure N-GP-31, "Calculation Of ASME Code Coverage For Section XI, Appendix VIII Ultrasonic Examinations."

This procedure has been demonstrated for detection of flaws located throughout the entire weld thickness.

Coverage obtained during axial scans is typically limited due to nozzle configuration.

In the circumferential scan direction the outer 85%-t is examined with the same vessel procedure as above and typically limited due to nozzle configuration.

To achieve additional coverage in the circumferential scan direction a second examination is performed with a procedure demonstrated for nozzle inside-radius UT. This procedure has been demonstrated for detection of flaws in the inner 15%-4 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.'"iOJ can "-C4r0umferen,-Scas

This procedure has been demonstrated for detection of flaws located throughout the entire weld thickness.

Coverage obtained during axial scans is typically limited due to nozzle configuration.

In the circumferential scan direction the outer 85%-t is examined with the same vessel procedure as above and typically limited due to nozzle configuration.

To achieve additional coverage in the circumferential scan direction a second examination is performed with a procedure demonstrated for nozzle inside-radius UT. This procedure has been demonstrated for 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.Axial Scans Circumferential Scans 100%.t0/ Inner 15%-t Outer 85%-t Examination Procedure:

This procedure has been demonstrated for detection of flaws located throughout the entire weld thickness.

Coverage obtained during axial scans is typically limited due to nozzle configuration.

In the circumferential scan direction the outer 85%-t is examined with the same vessel procedure as above and typically limited due to nozzle configuration, To achieve additional coverage in the circumferential scan direction a second examination is performed with a procedure demonstrated for nozzle inside-radius UT. This procedure has been demonstrated for 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.Axial Scans Circumferential Scans 100%4t Inner 15%-t Outer 85%-t Examination Procedure:

Thi',v procedure has been demonstrated for detection of flaws located throughout the entire weld thickness.

Coverage obtained during axi'al scans is typically limited due ;o nozzle configuration.

/n the circumferential scan direction the outer 85%-t is examined with the same vesse! procedure as above and typicallyv limited due to nozzle configuration.

To achieve additional coverage in the circumferential scan direction a second examination is performed with a procedure demonstrated for nozzle inside-radius UT. This procedure has been demonstrated for detection N,, of flaws in the inner 15%-t only. The nozzle inside-radius technique provides coverage since the component is modlied and scanning is pe, formed with several search units from the nozzle blend.Axial Scans Circumferential Scans 100%4__ Inner 15%-t Outer 85%4 Examination Procedure:

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 W1/2 on each side.This exarfination satisfies the requirements of ASME Sec. XI (2001 Edition with 2003 Addenda), Category B-D, for item number U-3.90, figure number iWB 2500-7(a) exarn volume, and was performed using ASME Sec XI, Appendix VIII qualified personnci, procedures, a.nd equipment as amended by the Final Rule.Prepard ey: George Chp nReview By: Ad Coti Lll Date:31222006

]Axial scans are performed with a procedure for the examination of vessel shell welds. This procedure has been demonstrated for deteciton of ,fla, C,'i. cehrouqhout the entire weld thickness.

Coverage obtained dr,, T.j axial scans is typically limited due to nozzle configuration.

in the circumferential scan direction the outer 85%-t is examined with the same vessael oprocedure as above and typically limited due to nozzle configuration.

To achieve additional coverage in the circumferential scan direction a second examination is performed with a procedure demonstrated for nozzle inside-radius UT. This procedure has been demonstrated for detection of flews in the inner 1 5%-t only. The nozzle inside-radius technique provides ad;i'nui coverage since the component is modeled and scan:ning is performed with several search units from the nozzle blend.Axial Scans Circumferential Scans 100%4 Inner 15%-t Outer 85%4t Examination Procedure:

This procedure has been demonstrated for detection of flaws located throughout the entire weld thickness.

Coverage obtained during axial scans is typically limited due to nozzle configuration.

In the circumferential scan direction the outer 85%-t is examined with the same vessel procedure as above and typically limited due to nozzle configuration.

To achieve additional coverage in the circumferential scan direction a second examination is performed with a procedure demonstrated for nozzle inside-radius UT. This procedure has been demonstrated for 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.Axial Scans Circumferential Scans 100%-t Inner 15%-t Outer 85%4 Examination Procedure:

This procedure has been demonstrated for detection of flaws located throughout the entire weld thickness.

Coverage obtained during axial scans is typically limited due to nozzle configuration.

In the circumferential scan direction the outer 85%-t is examined with the same vessel procedure as above and typically limited due to nozzle configuration.

To achieve additional coverage in the circumferential scan direction a second examination is performed with a procedure demonstrated for nozzle inside-radius UT. This procedure has been demonstrated for 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.Axial Scans Circumferential Scans 100%-t Inner 15%-t Outer 85%.4 Examination Procedure:

60°RL radial and tangential scans were performed from the shell surface.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 39% coverage.L ------------------

This procedure has been demonstrated for detection of flaws located throughout the entire weld thickness.

Coverage obtained during axial scans is typically limited due to nozzle configuration.

In the circumferential scan direction the outer 85%-t is examined with the same vessel procedure as above and typically limited due to nozzle configuration.

To achieve additional coverage in 1the circumferential scan direction a second examination is performed with a procedure demonstrated for nozzle inside-radius UT. This procedure has been demonstrated for 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.Axial Scans Circumferential Scans 100%-t Inner 15%-t Outer 85%-t Examination Procedure:

Radial scans are additionally limited for 22" of the circumference due to an insulation support ring. This limitation was from 3.0" (Wo) to the maximum required Wo (11.55") at the point of worst case scenario (bottom dead center). The worst case limitation value incrementally improves as the scanning progressed around the circumference.

Refer to the N5A Limitation Sketch for additional detail.60°RL radial and tangential scans were performed from the shell surface.The tangential scans were performed with +/-10 0 skew towards the weld and at varying distances from the weld. 30 Circumferential scans with a second procedure were also performed from the blend radius.

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.

This procedure has been demonstrated for detection of flaws located throughout the entire weld thickness.

Coverage obtained during axial scans is typically limited due to nozzle configuration.

In the circumferential scan direction the outer 85%-t is examined with the same vessel procedure as above and typically limited due to nozzle configuration.

To achieve additional coverage in.the circumferential scan direction a second examination is performed with a procedure demonstrated for nozzle inside-radius UT. This procedure has been demonstrated for 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.Axial Scans Circumferential Scans 100%-t Inner 15%-t Outer 85%-t Examination Procedure:

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 15 0/6-t only.These scans achieved 100% circumferential coverage of the inner 15%-t.100% of accessible surface was scanned resulting in 64% coverage.I0 IL ----- ---Prepared by: Bret Flesner Date: 03/25/06 Reviewedv b Adam Conti Date:03/25,06 ANII Review: Date: 51-9015478-000 Secton 5 Tab S Page 5 of 8 000345 /.?-Dgfq I A UT CALIBRATION DATA SHEET AREVA ustomer: Browns Ferry Unit 3 Exam Date: 0311112006 Calibration No.: N8A-CS01 System I Component LD.: RPV Nozzle NSA Component
