Full Penetration Welded Nozzles in Vessels - Inspection Program B Unit / Inspection Interval Applicability: Arkansas Nuclear One, Unit 2 (ANO-2) / Third (3rd) 10-Year Interval I. CODE REQUIREMENTS ASME Section XI, Table IWB-2500-1, Examination Category B-D, "Full Penetration Welded Nozzles in Vessels - Inspection Program B":
: 1) Item B3.130 requires a volumetric examination of the Steam Generator (SG) Nozzle-to-Vessel Weld volume, as depicted in Figures IWB-2500-7 (a) through (d).
: 2) Item B3.140 requires a volumetric examination of the SG Nozzle-to-Vessel Inner Radii, as depicted in Figures IWB-2500-7 (a) through (d).
 
II. RELIEF REQUEST Pursuant to 10 CFR 50.55a(g)(6)(i), Entergy Op erations, Inc. (Entergy) requests relief from achieving the Code-required coverage when performing volumetric examinations of the components identified in Table 1 below.
 
III. BASIS FOR RELIEF During ultrasonic examination of the nozzle-to-vessel welds and inner radii listed in Table 1 below, 100% coverage of the required examination volume could not be
 
obtained.
 
to 2CAN031203
 
Page 2 of 11 Due to the geometric configuration of the components and the close proximity of other structures which limited scan paths, the use of approved beam angles in the axial and circumferential direction were not able to achieve greater than 90% code required volume. See Table 1 below for additional information.
Radiography is not practical on these types of nozzle-to-vessel weld configurations, which prevent placement of the film and exposure source. To effectively perform any significant additional Code allowable ultrasonic examinations, modification and/or
 
replacement of the component would be required. The examinations performed on the subject items in addition to the examination of other vessel welds contained in the Inservice Inspection Program would detect generic degradation, if it existed, demonstrating an acceptable level of integrity.
 
IV. PROPOSED ALTERNATIVE EXAMINATIONS No alternative testing is proposed at this time. Entergy has examined these welds to the extent practical and will continue to perform pressure testing on the subject components as required by the Code.
V. CONCLUSION 10 CFR 50.55a(g)(6)(i) states:
 
The Commission will evaluate determinations under paragraph (g)(5) of this section that Code requirements are impractical. The Commission may grant such relief and may impose such alternative requirements as it determines is authorized by law and will not endanger life or property or the common defense and security and is otherwise in the public interest giving due consideration to the burden upon the licensee that could result if the requirements were imposed on the facility.

to 2CAN031203
 
Page 2 of 2 III. BASIS FOR RELIEF During surface examination of the vessel integral attachment weld, 100% coverage of the required examination area could not be obtained.
The configuration of the subject component is a metal key bracket with dimensions approximately twenty-two inches by eight inches welded on four sides. The bracket is integrally welded to the steam generate shell. The angle iron insulation support below the bracket is welded in place and restricts access to the lower portion of the weld. Code examination of this type of integral attachment weld requires a surface examination technique, such as a Liquid Dye Penetrate or Magnetic Particle Testing, of the weld crown surface and 1/2 inch of base material on either side of the weld toes.
However, due to the configuration of this integral attachment and associated welded insulation support, access to the lower weld and surrounding base material for examination purposes is limited.
 
In order to perform additional or alternative Code examinations, modification and/or replacement of the insulation support would be required. The examination performed on the available surface area of the subject item would detect generic degradation, if it existed, demonstrating an acceptable level of integrity.
IV. PROPOSED ALTERNATIVE EXAMINATIONS No alternative testing is proposed at this time. Entergy has examined the subject item to the extent practical.
 
V. CONCLUSION 10 CFR 50.55a(g)(6)(i) states:
The Commission will evaluate determinations under paragraph (g)(5) of this section that Code requirements are impractical. The Commission may grant such relief and may impose such alternative requirements as it determines is authorized by law and will not endanger life or property or the common defense and security and is otherwise in the public interest giving due consideration to the burden upon the licensee that could result if the requirements were imposed on

The examinations performed on the subject areas, in addition to the examination of similar welds contained in the program would detect generic degradation, if it existed, demonstrating an acceptable level of integrity. Therefore, Entergy requests the proposed relief be authorized pursuant to 10 CFR 50.55a(g)(6)(i).

Page 2 of 28 II. RELIEF REQUEST Pursuant to 10 CFR 50.55a(g)(6)(i), Entergy Op erations, Inc. (Entergy) requests relief from achieving the Code-required coverage when performing volumetric examinations of the components identified in Table 1 below.
III. BASIS FOR RELIEF
 
During ultrasonic examination of the piping welds listed in Table 1 above, greater than 90% coverage of the required examination volume could not be obtained.
Class 1 piping and components are often designed with welded joints such as nozzle-to-pipe, pipe-to-valve and pipe-to-pump which can physically obstruct a large portion of the required examination volume. For examinations performed after the 10 CFR 50.55a mandatory implementation date for Appendix VIII of Section XI, and Code coverage percentages reflect what is currently allowed by qualified Appendix VIII techniques.
Appendix VIII qualified Performance Demonstration Initiative (PDI) procedures have demonstrated that sound beams may potentially be attenuated and distorted when required to pass through austenitic weld metal. Still, the PDI qualified methods employ the best available technology for maximizing examination coverage of these types of welds. Examination was extended to the far side of the weld to the extent permitted by geometry, but this portion of the examination is not included in the reported coverage for welds examined under PDI and Appendix VIII rules.
These ultrasonic examinations have been performed over the course of the interval to varying code requirements and procedures. Entergy has used the best available and EPRI approved techniques to examine the subject piping welds. To improve upon these examination coverage percentages, modification and/or replacement of the component would be required. Consistent with the ASME Section XI sampling approach, examination of the subject welds, when combined with examinations that have been performed on other welds within the same Examination Category, is adequate to detect generic degradation, if it existed, demonstrating an acceptable level of integrity.
IV. PROPOSED ALTERNATIVE EXAMINATIONS No alternative testing is proposed at this time. Entergy has examined the subject items to the extent practical and will continue to perform pressure testing on the subject areas as required by the Code.
V. CONCLUSION 10 CFR 50.55a(g)(6)(i) states:
The Commission will evaluate determinations under paragraph (g)(5) of this section that Code requirements are impractical. The Commission may grant such relief and may impose such alternative requirements as it determines is authorized by law and will not endanger life or property or the common defense and security and is    to 2CAN031203

Integral Attachments for Piping, Pumps and Valves Unit / Inspection Interval Applicability: Arkansas Nuclear One, Unit 2 (ANO-2) / Third (3rd) 10-Year Interval I. CODE REQUIREMENTS ASME Section XI, Table IWB-2500-1, "Examination Category B-K, Integral Attachments for Piping, Pumps, and Valves", Item B10.20 requires a volumetric or surface examination, as applicable, of integrally welded attachments.
II. RELIEF REQUEST Due to the geometric configuration of the integrally welded attachment and associated pipe support, the code examination area, as depicted in ASME Section XI, cannot be examined to the extent of obtaining full code coverage. Pursuant to 10 CFR 50.55a(g)(6)(i), Entergy Operations, Inc. (Entergy) requests permission to perform surface examination within the limitations described in Table 1 of this relief request. Table 1 Limited B-K-1 Examination Item # Item ID Description Coverage (%) Reason for Limitation B10.20 22-071W Integrally Welded Attachment Way Vertical Restraint 88 Structural interference at the end of lugs where they contact the support.
to 2CAN031203
 
Page 2 of 2 III. BASIS FOR RELIEF During surface examination of the pipe support integral attachment weld, 100% coverage of the required examination area could not be obtained.
 
The configuration of the subject component is four 5/8" x 1" x 1" lugs, placed 4 1/16" apart end-to-end in pairs at 0° and 180° on the vertical pipe. The lugs are integrally welded to the pipe with full penetration welds. The two piece four-inch wide hanger strap is positioned and bolted between the end to end lugs, contacting the upper lugs which support the vertical pipe. Code examination of this type of integral attachment weld requires a surface examination technique, such as Liquid Dye Penetrate or Magnetic Particle Testing, of the weld crown surface and 1/2  inch of base material on either side of the weld toes. However, due to the configuration of this integral attachment and associated hanger strap, access to the weld ends and surrounding base material for examination purposes is limited.
 
In order to perform additional or alternative Code examinations, modification and/or replacement of the component would be required. The examination performed on the available surface area of the subject item would detect generic degradation, if it existed, demonstrating an acceptable level of integrity.
 
IV. PROPOSED ALTERNATIVE EXAMINATIONS No alternative testing is proposed at this time. Entergy has examined the subject item to the extent practical.
 
V. CONCLUSION 10 CFR 50.55a(g)(6)(i) states:
The Commission will evaluate determinations under paragraph (g)(5) of this section that Code requirements are impractical. The Commission may grant such relief and may impose such alternative requirements as it determines is authorized by law and will not endanger life or property or the common defense and security and is otherwise in the public interest giving due consideration to the burden upon the licensee that could result if the requirements were imposed on
 
the facility.
Entergy believes that it is impractical to obtain greater examination coverage on these areas. To obtain additional coverage would necessitate modification and/or replacement of the component. The examinations performed on the subject areas, in addition to the examination of similar welds contained in the program would detect generic degradation, if it existed, demonstrating an acceptable level of integrity.

Radiography is not practical on these types of nozzle-to-vessel weld configurations which prevent placement of the film and exposure source. To effectively perform any significant additional Code allowable ultrasonic examinations, modification and/or
 
replacement of the component would be required. The examinations performed on the subject items in addition to the examination of other vessel welds contained in the Inservice Inspection (ISI) program would detect generic degradation, if it existed, demonstrating an acceptable level of integrity.
 
IV. PROPOSED ALTERNATIVE EXAMINATIONS No alternative testing is proposed at this time. Entergy has examined these welds to the extent practical and will continue to perform pressure testing on the subject components as required by the Code.
 
V. CONCLUSION 10 CFR 50.55a(g)(6)(i) states:
 
The Commission will evaluate determinations under paragraph (g)(5) of this section that Code requirements are impractical. The Commission may grant such relief and may impose such alternative requirements as it determines is authorized by law and will not endanger life or property or the common defense and security and is otherwise in the public interest giving due consideration to the burden upon the licensee that could result if the requirements were imposed on
 
the facility.

CODE REQUIREMENTS ASME Section XI, Table IWC-2500-1, Examination Category C-B, "Pressure Retaining Nozzle Welds in Vessels - Inspection Program B":
: 1) Item C2.21 requires a volumetric and surface examination of the Nozzle-to-Shell Weld volume, as depicted in Figure IWC-2500-4 (a) or (b).
 
II. RELIEF REQUEST Pursuant to 10 CFR 50.55a(g)(6)(i), Entergy Op erations, Inc. (Entergy) requests relief from achieving the Code-required coverage when performing volumetric examinations of the components identified in Table 1 below.
 
III. BASIS FOR RELIEF During ultrasonic examination of the Feedwater Nozzle-to-Shell Weld listed in Table 1 below, 100% coverage of the required examination volumes could not be obtained. 
 
Due to the close proximity of one of the steam generator insulation brackets, located
 
around the circumference of the vessel and directly below the Feedwater nozzles, scan paths from below the nozzle were impeded and 100% examination of the code required volume was not achieved. See Table 1 below for additional information.
 
There are several insulation bracket rings located around the circumference of the steam generator. These brackets facilitate supporting the many insulation panels surrounding the circumference of the steam generator. Removal of the subject bracket requires    to 2CAN031203
 
Page 2 of 4 removal of all insulation panels directly supported by that ring as well as removal or engineered rigging of all insulation rings and panels above the removed ring. The insulation rings are not bolted directly to the steam generator shell therefore each lower elevation ring helps support the above rings and insulation panels.
Radiography is not practical on these types of nozzle-to-vessel weld configurations, which prevent placement of the film and exposure source. To effectively perform any significant additional Code allowable ultrasonic examinations, modification and/or removal are replacement of the insulation ring would be required. The examinations performed on the subject items in addition to the examination of other vessel welds contained in the Inservice Inspection program would detect generic degradation, if it existed, demonstrating an acceptable level of integrity.

Pressure Retaining Welds in Austenitic Stainless Steel or High Alloy Piping - Inspection Program B Unit / Inspection Interval Applicability: Arkansas Nuclear One, Unit 2 (ANO-2) / Third (3rd) 10-Year Interval I. CODE REQUIREMENTS ASME Section XI, Table IWC-2500-1, Examination Category C-F-1, "Pressure Retaining Welds in Austenitic Stainless Steel or High Alloy Piping - Inspection Program B":
: 1) Item C5.11, as allowed by the Risk Informed process, requires a volumetric examination of circumferential piping welds Nominal Pipe Size (NPS) 4 or larger, as depicted in Figure IWC-2500-7 and Risk-Informed Inservice Inspection Evaluation Procedure, Electric Power Research Institute (EPRI) Report No.
TR-106706, Interim Report, June 1996.
: 2) Item R1.20 requires a volumetric examination of circumferential piping welds as depicted in Figure IWC-2500-7 and Risk-Informed Inservice Inspection Evaluation Procedure, EPRI Report No. TR-106706, Interim Report, June 1996.
ASME Code Case N-460 allows a reduction in coverage due to interference or geometry as long as the overall coverage is greater than 90%.
II. RELIEF REQUEST Pursuant to 10 CFR 50.55a(g)(6)(i), Entergy Op erations, Inc. (Entergy) requests relief from achieving the Code-required coverage when performing volumetric examinations of the components identified in Table 1 below.
 
to 2CAN031203
 
Page 2 of 9 III. BASIS FOR RELIEF During ultrasonic examination of the piping welds listed in Table 1 above, greater than 90% coverage of the required examination volume could not be obtained.
Class 2 piping and components are often designed with welded joints such as nozzle-to-pipe, pipe-to-valve and pipe-to-pump which can physically obstruct a large portion of the required examination volume. For examinations performed after the 10 CFR 50.55a mandatory implementation date for Appendix VIII of Section XI, and Code coverage percentages reflect what is currently allowed by qualified Appendix VIII techniques. Appendix VIII qualified Performance Demonstration Initiative (PDI) procedures have demonstrated that sound beams may potentially be attenuated and distorted when required to pass through austenitic weld metal. Still, the PDI qualified methods employ the best available technology for maximizing examination coverage of these types of welds. Examination was extended to the far side of the weld to the extent permitted by geometry, but this portion of the examination is not included in the reported coverage for welds examined under PDI and Appendix VIII rules.
These ultrasonic examinations have been performed over the course of the interval to varying code requirements and procedures. Entergy has used the best available and EPRI approved techniques to examine the subject piping welds. To improve upon these examination coverage percentages, modification and/or replacement of the component would be required. Consistent with the ASME Section XI sampling approach, examination of the subject welds, when combined with examinations that have been performed on other welds within the same Examination Category, is adequate to detect generic degradation, if it existed, demonstrating an acceptable level of integrity.
IV. PROPOSED ALTERNATIVE EXAMINATIONS No alternative testing is proposed at this time. Entergy has examined the subject items to the extent practical and will continue to perform pressure testing on the subject areas as required by the Code.
V. CONCLUSION 10 CFR 50.55a(g)(6)(i) states:
The Commission will evaluate determinations under paragraph (g)(5) of this section that Code requirements are impractical. The Commission may grant such relief and may impose such alternative requirements as it determines is authorized by law and will not endanger life or property or the common defense and security and is otherwise in the public interest giving due consideration to the burden upon the licensee that could result if the requirements were imposed on the facility.
