RAI-2

2. The sketches provided do not provide clear information for the NRC staff to evaluate the exam coverage obtained or determine the cause of the impracticality of the examination. For examples of required information refer to the IndustryiNRC Information Exchange Public Meeting held on January 13 -15, 2015,(1) for a discussion of the NRC staff's expectations for the content of an inspection sketch/diagram (see slide 6 for the information expected and slide 12 for a sample sketch/diagram). This presentation clarifies what a satisfactory inspection sketch should clearly show, e.g., the required examination volume and achieved examination volume, such that the NRC staff can determine the percent examination coverage obtained by a licensee. The sketch/diagram should show relevant dimensions, such as wall thickness and weld dimensions.

Response to RAI 2:

Additional sketches have been provided that provide the wall thicknesses and weld dimensions of the welds. Code coverage sketches can be found within the attached figures for each weld and show the limitations imposed by the component configurations.

RAI-3

3. Provide the examination methodology used (i.e., ASME Section XI, Appendix VIII or other methodology used). Refer to slide 6 of industry/NRC Information Exchange Public Meeting held on January 13 -15, 2015.

Response to RAI 3:

The examination methodology (e.g., ASME Section XI Appendix VIII) is provided within Tables 3RR-19.l, 3RR-19.2, 3RR-20.1, and 3RR-20.2.

Attachment 1 to PLA-7371 Page 3 ofll1 Response to Requested Additional Information (Continued)

RAI-4

4. Provide results of the examination: i.e., whether indications were detected or not. If indications were detected provide descriptions of how they have been dispositioned.

Refer to slide 9 of industry/NRC Information Exchange Public Meeting held on January 13 -15, 2015.

Response to RAI 4:

No indications were detected within the covered volumes of any of the subject welds.

This is now stated within the revised Tables 3RR-19.1, 3RR-19.2, 3RR-20.l, and 3RR-20.2.

RAI-5

5. Discuss any industry or plant-specific operating experience regarding potential degradation and potential severe loading for the subject weld and associated components.

Response to RAI 5:

A discussion of operating experience has been added within the "Basis for Relief' section for each of the revised relief requests that are attached. Plant-specific experience is discussed that includes evidence of some prior susceptibility to Intergranular Stress Corrosion Cracking (IGSCC) at the Unit 1 nozzle-to-safe end welds NiB and N2J, that have since been corrected with an Inconel 52 weld overlay. Cases of stress corrosion cracking that have occurred in stainless steel materials throughout the industry are concerns that have been addressed by application of methods like Mechanical Stress Improvement (MSIP) and Hydrogen Water Chemistry, which are proven to limit the effects of IGSCC on stainless steel. Additionally, the performance of VT-2 visual examinations as well as online leakage monitoring provides assurance that no IGSCC flaws have gone through wall. There is no applicable industry or plant-specific operating experience to indicate that significant service-induced degradation had occurred for the subject welds and associated components since, and evidence of such degradation would have been detected by the examinations that were performed.

Attachment 1 to PLA-7371 Page 4 of 11 Response to Requested Additional Information (Continued)

Relief Requests 3RR-21. Revision 0:

RAI-I. item a:

1. The NRC staff requests that the licensee:

a. Provide schematic diagram of each weld and the associated components as well as provide sketches or scan plots detailing the insonification angles, ultrasonic wave modes (e.g., refracted shear and longitudinal waves), and volumetric coverage achieved by each angle on each weld.

Response to RAI 1. item a:

A schematic diagram depicting the isonification angles, ultrasonic weld modes, and volumetric coverage has been added to the att ached figures for each weld. Additionally, the ultrasonic datasheets have been included within the figures. These datasheets identify details of the ultrasonic testing (UIT) scanning apparatus including transducer size, frequency, wave modality, and isonification angles.

RAI-1i item b:

b. Mark clearly on the sketches the volume (i.e., the weld materials and the heat affected zone (HAZ) of base materials) examined and missed (i.e., not examined due to access and geometrical constraints). Please refer to the Industry/NRC Technical Information Exchange Public Meeting held on January 13-15, 2015, for a discussion of the NRC staffs expectations for the content of an inspection sketch/diagram (see slide 6 for the information expected and slide 12 for a sample sketch/diagram).

Response to RAI-1. item b:

The required inspection volumes can be found within the attached figures for each weld as well as volumes examined and missed, which have also been added to the attached figures for each weld.

Attachment 1 to PLA-7371 Page 5 of 11 Response to Requested Additional Information (Continued)

RAIL-I, item c:

c. Discuss why the refracted longitudinal waves (L-waves) were not used as part of "Best Effort" examination. The NRC staff notes that the L-waves have been shown capable of detecting planar flaws on the far-side volume (weld root and HAZ) of cast austenitic stainless steel (CASS) and stainless steel weld and base materials.

Response to RAI 1. item c:

Refracted longitudinal waves were employed as part of a "Best Effort" examination of the far-side weld volume. These waves are depicted within the attached figures for each weld. Additionally, a "Best Effort" coverage, while not code creditable, is provided within Tables 3RR-21.1 and 3RR-21.2.

RAI-I. item d:

d. Provide coverage summary table detailing percentage of axial scan coverage (upstream and downstream) and percentage of circumferential scan coverage (upstream and downstream), and the "Best Effort" scan coverage. As an example refer to relief requests by Turkey Point and North Anna.(a*

Response to RAI 1. item d:

A coverage summary table detailing the percentage of axial scan coverage, circumferential scan coverage, total coverage, and code creditable coverage is provided for each weld within Tables 3RR-21 .1 and 3RR-21 .2.

RAI-I. item e:

e. Provide discussions on whether use of alternative ultrasonic testing (UT) methods would have increased the examination coverage.

(2) Turkey Point, Units 3 and 4, "Closeout of the Fourth Ten-Year Inservice Inspection (1S1) Interval, Relief Request Nos. 15, 16, 17," dated February 13, 2015, (ADAMS M1L15062A279); and, North Anna Power Station, Unit 2, "ASME Section XI Inservice Inspection Program Relief Request N2-14-LMT-002 - Fourth Interval, Period 1 Limited Examinations," dated April 21, 2014, (ADAMS ML14l115A066 )

Attachment 1 to PLA-7371 Page 6 ofl1l Response to Requested Additional Information (Continued)

Response to RAI 1. item e:

There are no qualified alternative UT methods that could have increased examination coverage for these components. The use of alternative UT methods that were not demonstrated to Performance Demonstration Initiative (PDI)/Appendix VIII were not used as they are considered unproven and unacceptable, and additional Code credit cannot be obtained. SSES utilizes the PDI procedure PDI-UT-2 for the inspection guidance with the associated tables 1 and 2 to perform the qualified inspection techniques. Although there are no specific plans currently in place to pursue qualified alternative UT methods for these components, SSES continues to partner with Electric Power Research Institute (EPRI), the PDI, ISI vendors and other industry sources to encourage the development and provide an awareness of improved examination techniques. The goal of these initiatives is to enhance coverage and flaw detection conumensurate with radiation dose reduction. Examination procedures are revised on a continuing basis to incorporate proven techniques for a higher level of safety and quality as they become available. The examinations and techniques used today exceed the examinations conducted in the past on each component. These examinations were performed to the maximum extent practical.

RAI-2

2. a. Provide materials of construction for each weld and the associated components (e.g., pipes, nozzles, pumps, valves, branch connections) in this relief request.

b. Provide wall thickness for each weld.

Response to RAT 2. items a and b:

All welds within the subject of this relief request are stainless steel. This information is now provided in Tables 3RR-21.1 and 3RLR-2 1.2.

Wall thickness profiles for each weld within the subject of this relief are provided in the attached figures.

Attachment 1 to PLA-7371 Page 7 of 11 Response to Requested Additional Information (Continued)

RAI-3

3. For each weld in this relief request, provide inspection history.

a. Discuss whether the licensee identified any indication(s) during construction and preservice inspections (i.e., volumetric or surface examination(s), or both) on the volume not covered by the UT of the affected welds.

b. Discuss whether the licensee identified any indication(s) in these welds in the previous 10-year inservice inspection (ISI) intervals.

c. Discuss whether the licensee identified any indication(s) in these welds in the third 10- year ISI interval.

d. Discuss disposition of identified indications in parts a, b, and c, above.

Response to RAI 3. items a through d:

No relevant indications were identified in any of the subject welds. A table providing a summary of inspections (including any identified acceptable geometric indications) is provided within Tables 3RR-21 .1 and 3RR-21 .2.

Attachment 1 to PLA-7371 Page 8 of 11 Response to Requested Additional Information (Continued)

RAI.-4:

4. The NRC staff notes that this relief request did not provide any discussions on whether a qualified UT was used to examine these welds.

a. Did the licensee use a qualified UT (e.g., according to Appendix VIII of Section XI that was administered by the Performance Demonstration Initiative program) to volumetrically examine these welds?

b. If Appendix VIII was used for the UT qualification, provide supplement(s) number that is applicable to this relief request.

c. Otherwise, provided subarticles and/or appendices (e.g., Appendix I of Section XI) of the ASME Code, the licensee used for the UT qualifications.

Response to RAI 4. items a through e:

The examination methodology (ASMIE Section XI Appendix VIII) as well as Performance Demonstration Initiative Supplement number is provided within the revised Tables 3RR-2 1.1 and 3RR-21.2.

RAI-5

5. According to RI-SI program, the welds that are classified as Item Number Ri. 11 are prone to potential degradation by thermal fatigue. Discuss whether any supplemental inspection (e.g., surface examination) was performed on the volume not examined by UT to ensure structural integrity of the system.

Response to RAT 5:

No supplemental inspection beyond the refracted longitudinal wave inspection of the far-side volume was performed on the subject welds. This is currently not a procedural or a Code requirement. Performance of VT-2 visual examinations in accordance with examination category B-P as well as online leakage monitoring provides additional assurance that significant service-induced degradation would have been detected by the examinations that were performed.

Attachment 1 to PLA-7371 Page 9 of 11 Response to Requested Additional Information (Continued)

RAI-6. item a:

6. The NRC staff notes that when the RI-ISI program is established, the welds shall be selected such that the ASME Code required examination coverage is achievable.

a. Discuss whether there were other welds with the same risk significance subject to the same degradation mechanism that could be examined and achieved the required examination coverage.

b. If the answer to part a. is yes, then will the licensee substitute that weld for the subject weld in its RI-ISI program update?

Response to RAT 6. item a and b:

Yes, additional welds with the same risk significance subject to the same degradation mechanisms could be examined that may have a higher likelihood of achieving 100%

coverage.

Currently, two of the welds presented in this relief request are selected for inspection during the 4 th 10-Year Inservice Inspection Interval (e.g., DCA2071-FW-4 and DCA207 1-FW-5) with other welds substituted for by welds within the same system for welds that may achieve greater coverage.

RAI-6. item c:

c. Discuss whether there exist additional weld with the same risk significance subject to the same degradation mechanism that could be chosen for examination provided that the coverage of chosen additional weld is greater than the coverage of the subject weld to supplement the reduced volumetric coverage of the subject weld.

Response to RAI 6. item c:

Welds were selected, in part, because previousSection XI examination history exists in some cases. Comparison of examination results over time is critical to detect service induced degradation. Although Susquehanna could select only weld locations where greater than 90% examination coverage is possible (when available based on selection criteria), meeting the purpose of the Code requires selecting a mix of not only piping-to-piping welds that have a higher likelihood of achieving 100% coverage, but also single sided exams such as piping-to-valve welds. The ASME Code allows only 50% Code

Attachment 1 to PLA-7371 Page l0 ofil1 Response to Requested Additional Information (Continued) coverage for single-sided examinations. No unacceptable indications were found in any of the covered volumes for any Risk Informed 1SI inspections during the 3 rd 10-Year Inservice Inspection Interval.

RAI-7

7. Given the reduced inspection coverage of the welds under consideration, discuss the need for compensatory measures such as frequent plant walk downs, VT-2 examination, or leak detection systems and whether such compensatory measures have been implemented.

Response to RAI 7:

A discussion of alternative examinations can be found within the "Proposed Alternative Examinations" section of this relief request. This includes VT-2 examinations and leakage detection systems.

RAI-8

8. Discuss any industry or plant-specific operating experience regarding potential degradation (e.g., stress corrosion cracking and corrosion) and potential severe loading (e.g., vibration, water hammer, and overloading) for the subject weld and associated components.

Response to RAI 8:

A discussion of operating experience has been added within the "Basis for Relief' section for each of the revised relief requests that are attached. Plant-specific experience is discussed that includes evidence of some prior susceptibility to Intergranular Stress Corrosion Cracking (IGSCC) at the Unit 1 nozzle-to-safe end welds NIB and N2J, that have since been corrected with an Inconel 52 weld overlay. Cases of stress corrosion cracking that have occurred in stainless steel materials throughout the industry are concerns that have been addressed by application of methods like Mechanical Stress Improvement (MSIP) and Hydrogen Water Chemistry, which are proven to limit the effects of IGSCC on stainless steel. Additionally, the performance of VT-2 visual examinations as well as online leakage monitoring provides assurance that no IGSCC flaws have gone through wall. There is no applicable industry or plant-specific operating experience to indicate that significant service-induced degradation had occurred for the

Attachment 1 to PLA-7371 Page 11 ofl11 Response to Requested Additional Information (Continued) subject welds and associated components since, and evidence of this would have been detected by the examinations that were performed.

Relief Request 3RR-21, Revision 1 discusses SSES experience of a fatigue failure of a 4-inch Reactor Recirculation weld in 2012, however, this vibrational fatigue was evaluated separate from the RI-ISI program requirements, which is consistent with requirements in EPRI TR-l1126557, Revision B-A. This experienced fatigue failure is treated outside the RI-ISI program requirements and is not related to any acceptable basis for performance of these examinations. The condition has also been evaluated for the station, and this provides some assurance of no other unevaluated severe loading concerns remaining for any of the subject welds in this relief request.

Description:==

Alternative Requirements to the Examination of Full Penetration Welds of Nozzles in Vessels Component Number: Ref. Tables 3RR-19.1 and 3RR-19.2

,CODE REOLUIREMENT Susquehanna Station Electric Station (SSES), Units 1 and 2 each have 30 Reactor Pressure Vessel (RPV) nozzles fabricated with full penetration nozzle-to-vessel shell (or head) welds.

These nozzles are as follows:

Nozzle ID System N1A, B Reactor Recirculation N2A - H, J, K Reactor Recirculation N3A - D Main Steam N4A - F Feedwater N5A, B Core Spray N6A, B Residual Heat Removal - Head Spray N7 Reactor Pressure Vessel - Head Vent N8A, B Reactor Recirculation Instrumentation N9 Control Rod Drive (capped)

Table IWB-2500-1, Examination Category B-D, Item Number B3.90, requires volumetric examination of all RPV nozzle-to-vessel welds in accordance with the examination requirements illustrated in Figure IWB-2500-7.

BASIS FOR RELIEF Pursuant to 10CFR50.55a(g)(5)(iii),relief is requested on the basis that conformance with the specified Code requirement has been determined to be impractical.

The burden caused by compliance with the examination requirements of ASME Section XI includes required modification of plant components to remove obstructions, redesigning of plant systems, and replacement of components where geometry is inherent to component design.

Relief Request: 3RR-19, Revision 1 Attachment 2 to PLA-7371 Page 2 of 86 Complete examination of all of the aforementioned SSES Units 1 and 2 Examination Category B-D nozzle-to-vessel welds is not practical due to the nozzle forging configuration. In each case, the radius of curvature of the nozzle forging (the nozzle side of the weld) causes the ultrasonic search unit to lift and lose contact, thereby limiting complete volumetric examination of the ASME Section XI required examination volume. This examination limitation affects both the transverse and parallel scans of those components listed in Table 3RR- 19.1 and Table 3RR- 19.2.

Alternate means, such as small search units and full vee path examinations, were considered, but were found to be ineffective in improving examination coverage.

Due to the limitations created by the configuration of the vessel nozzles, there are no means of Appendix VIII qualified demonstrated ultrasonic inspection that may result in additional coverage.

Examinations of two Feedwater nozzle-to-vessel welds - N4A and N4D - are further limited due to plant design obstructions. A spacing of approximately 4.5 inches between the N4 and the Nl11 nozzles restricts examination of an arc of approximately 45 degrees (12.5%) of the affected nozzle-to-vessel welds.

Automatic examination of the Reactor Recirculation discharge nozzle-to-vessel weld N2J is limited due to plant design obstructions on Unit 2. The proximity of the N2J and N8D nozzles restricts examination of an arc of approximately 45 degrees (12.5 %) of the affected nozzle-to-vessel welds. Note that these obstructions for the N2J nozzle exist on Unitl, however, the exams performed on the Unit 1 N2J nozzles during this interval utilized the reduced coverage volume under Code Case N-613-1l.( 3 )

Unit 1 nozzle-to-safe end welds N1 B and N2J received a weld overlay due to relevant indications found to be caused by Intergranular Stress Corrosion Cracking (IGSCC) in the Second Ten-Year Interval. These indications initiated and grew prior to Mechanical Stress improvement Process (MSIP) and Hydrogen Water Chemistry (HWC) adoption, which are proven methods of IGSCC mitigation. These welds have subsequently had an Inconel 52 weld overlay installed to correct the issue. There is no applicable internal operating experience regarding the subject welds.

No other internal or external operating experience reviewed is relevant regarding potential degradation or severe loading for the subject welds.

PROPOSED ALTERNATE EXAMINATIONS The examinations were performed to the maximum extent practicable in accordance with Appendix VIII of ASME Section XI which is a proven means of identifying any degradation in the covered volumes. The proposed alternative is the maximum coverage achievable shown in Tables 3RR-19.1 and 3RR-19.2.

Relief Request: 3RR-19, Revision 1 Attacbment 2 to PLA-7371 Page 3 of 86 The RPV pressure retaining welds are also subject to VT-2 visual examination during system pressure testing in accordance with the requirements of Examination Category B-P.

Online leakage monitoring for the subject welds is provided by the drywell floor drain sump monitoring system. This system has Technical Specification required monitoring (TS 3.4.4.1) every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. If leakage were to be detected beyond the limits identified in TS 3.4.4, the unit would be shutdown and any leakage would be identified and repaired.

Reference:

Table IWB-2500-1 Examination Category: B-A Item Number: B 1.12, B 1.22

Description:

Alternative Requirements to the Examination of Pressure Retaining Welds in the Reactor Pressure Vessel Component Number: Ref. Tables 3RR-20.1 and 3RR-20.2 CODE REOUIREMENT Table TWB-2500-1, Examination Category B-A, Item Number B 1.12, requires volumetric examination of essentially 100% of the weld length of all longitudinal shell welds in accordance with the examination requirements illustrated in Figure IWB-2500-2.

Table IWB-2500-l, Examination Category B-A, Item Number B 1.22, requires volumetric examination of essentially 100% of the weld length of the bottom head meridional welds in accordance with the examination requirements illustrated in Figure IWB-2500-3.

BASIS FOR RELIEF Pursuant to 10CFR50.55a(g)(5)(iii), relief is requested on the basis that conformance with the specified Code requirement has been determined to be impractical.

Examinations of the affected welds were performed to the maximum extent practical.

For item Number B 1.12, longitudinal welds, the total examination coverage obtained is the maximum practical due to interference with permanent RPV mirror insulation support steel.

The burden that is caused by compliance with the examination requirements of ASME Section XI includes modification of plant components to remove obstructions, redesigning of plant systems, and replacement of components where geometry is inherent to component design.

For Item Number B 1.22, meridional welds, the total examination coverage obtained is the maximum practical due to interference with the vessel support skirt and Control Rod Drive (CRD) obstructions.

Modification or temporary removal of the RPV mirror insulation support steel, vessel support skirt, and CR1) obstructions is a significant burden to achieve any additional examination coverage.

No internal or external operating experience reviewed is relevant regarding potential degradation or severe loading for the subject welds.

Relief Request: 3RR-20, Revision 1 Attachment 3 to PLA-7371 Page 2 of 36 PROPOSED ALTERNATE EXAMINATIONS The examinations were performed to the maximum extent practicable in accordance with Appendix VIII of ASME Section XI which is a proven means of identifying any degradation in the covered volumes. The proposed alternative is the maximum coverage achievable shown in Table 3RR-20. 1 and Table 3RR-20.2.

The RPV pressure retaining welds are also subject to VT-2 visual examination during system pressure testing in accordance with the requirements of Examination Category B-P.

Online leakage monitoring for the subject welds is provided by the drywell floor drain sump monitoring system. This system has Technical Specification required monitoring (TS 3.4.4.1) every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. If leakage were to be detected beyond the limits identified in TS 3.4.4, the unit would be shutdown and any leakage would be identified and repaired.

APPLICABLE TIME PERIOD Relief is requested for the third ten-year inspection interval of the Inservice Inspection Program for SSES Units 1 and 2.

3RR-01 Examination Category: N/A Item Number: Rl.11, Rl.20

Description:

Alternative Requirements to the Examinations in the Risk-Infonned and Augmented Programs Component Number: Ref. Tables 3RR-21.l and 3RR-21.2 CODE REOUIREMENT The components listed in Table 3RR-21 .1 and 3RR-21 .2, subject to the examination requirements of the Risk Informed Inspection Program and various Augmented Inspection Programs, are discussed in this relief request. Detail of the Risk Informed Inspection Program can be found within approved relief request 3RR-01.*(4)

Essentially 100% of the circumferential welds selected are required to be examined. As defined by ASMIE Code Case N-460,(5

• essentially 100% means more than 90% of the examination volume of each weld, where reduction in coverage is due to interference by another component or component geometry.

BASIS FOR RELIEF Pursuant to 10OCFR50.55a(g)(5)(iii), relief is requested on the required 100% volumetric examination on the basis the Code requirement is impractical as described by the balance of this request. This relief request addresses welds for the third 10-year interval where _*90% of the examination volume was obtained.

Complete examination in accordance with the governing inspection requirements is not practical due to the limitations noted in Table 3RR-21.1 and Table 3RR21.2. All examinations were completed to the maximum extent practical with qualified, demonstrated Appendix VIII / PDI techniques, Relief is requested for those components listed in Table 3RR-21 .1 and Table 3RR21 .2 where the governing inspection requirements are impractical to implement due to access restrictions and/or metallurgical constraints.

(4) NRC Safety Evaluation Report [related to Relief Request No. 3RR-0 1], dated July 28, 2006, "Third 10-Year Inservice Inspection (ISI) Interval Program Plan (TAC Nos. MC 1181 and 1182)," (AIDAMVS MLO5 1990330)

(5) ASME Code Case N-460, "Alternative Examination Coverage for Class 1 and Class 2 Welds,Section XI, Division 1

Relief Request: 3RR-21, Revision 1 Attachment 4 to PLA-7371 Page 2 of 66 The burden that is caused by compliance with the examination requirements of ASME Section XI includes required modification of plant components to remove obstructions, redesigning of plant systems, and replacement of components where geometry is inherent to component design.

For the welds listed in the table, it has been determined that the obstruction or interference could not be removed without significant work, increased radiological dose, and/or damage to plant equipment.

A 600 refracted longitudinal "Best Effort" exam was performed on the far side volume for all single side access components. The percentage of coverage for these best effort exams can be viewed in Tables 3RR-2 1.1 and 3RR-2 1.2. No other supplemental inspections (e.g. surface examinations) were performed on the subject welds.

Of the welds presented in 3RR-2 1, two of the welds are currently selected for inspection during the 4th 10-Year Inservice Inspection Interval (DCA207l-FW-4 and DCA2071-FW-5) with the other welds substituted for by welds within the same system for welds that may achieve greater coverage. Welds were selected, in part, because previousSection XI examination history exists in some cases. Comparison of examination results over time is critical to detect service induced degradation. Although Susquehanna could select only weld locations where greater than 90%

examination coverage is possible (when available based on selection criteria), meeting the purpose of the Code requires selecting a mix of not only piping-to-piping welds that have a higher likelihood of achieving 100% coverage, but also single-sided exams such as piping-to valve-welds, piping-to-reducer welds, etc. The ASME Code allows only 50% Code coverage for single-sided examinations. No unacceptable indications were found in any of the covered volumes for any Risk Informed ISI inspections during the 3r 10-Year Inservice Inspection Interval.

There are no alternative methods of qualified, demonstrated ultrasonic testing that result in an increased code coverage. Examination of the weld using radiography was determined to be impractical due to the impact on surrounding area work and the increased exposures that would result. Additionally, draining affected piping for radiography was considered to also result in an increased dose in the surrounding areas.

Susquehanna experienced a fatigne failure of a 4" Reactor Recirculation weld in 2012, however, per Section 2.5.2 of EPRI TR-1 12657, Revision B-A,( 6

• vibrational fatigue should be treated outside the RI-IS I program and is thus irrelevant to the context of this relief. In the course of investigation of the 4" fatigue failure, an IGSCC flaw was discovered. The IGSCC flaw was found to be independent of the fatigue failure. The IGSCC indication was found to be arrested in the IGSCC resistant weld material, and would not have propogated through wall. These cases of stress corrosion cracking have occurred in stainless steel materials throughout the industry.

These concerns are addressed by application of methods such as Mechanical Stress Improvement (MSIP) and Hydrogen Water Chemistry (HWC) which are proven to limit the effects of IGSCC on stainless steel. Additionally, the performance of VT-2 visual examinations in accordance with examination category B-P as well as online leakage monitoring provides assurance that no (6) Electric Power Research Institute (EPRI) Topical Report (TR) 112657 Rev. B-A, "Revised Risk-Informed Inservice Inspection Evaluation Procedure"

Relief Request: 3RR-2 1, Revision 1 Attachment 4 to PLA-7371 Page 3 of 66 IGSCC flaws have gone through wall. No other internal or external operating experience reviewed is relevant regarding potential degradation or severe loading for the subject welds.

PROPOSED ALTERNATE EXAMINATIONS The examinations were performed to the maximum extent practicable with personnel and procedures qualified in accordance with Appendix VIII of ASME Section XI which is a proven means of identifying any degradation in the covered volumes. A 60° refracted longitudinal "Best Effort" exam was performed on the far side volume for all single side access components. The percentage of coverage for these best effort exams can be viewed in Tables 3RR-21 .1 and 3RR-21.2.

All welds listed in Tables 3RR-21.1 and 3RR-21.2 are Class 1 welds subject to VT-2 visual examination during system pressure testing in accordance with the requirements of Examination Category B-P.

All subject welds are located within the primary containment structure. Online leakage monitoring located inside primary containment is provided by the drywell floor drain sump monitoring system.

This system has Technical Specification required monitoring (TS 3.4.4.1) every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. If leakage were to be detected beyond the limits identified in TS 3.4.4, the unit would be shutdown and any leakage would be identified and repaired.

APPLICABLE TIME PERIOD Relief is requested for the third ten-year inspection interval of the Inservice Inspection Program.
