SECTION XI INSERVICE INSPECTION (ISI) PROGRAM SECOND TEN-YEAR INSERVICE INSPECTION INTERVAL REQUEST FOR RELIEF PDI-2 TVA requests approval for an alternative to ASME Section XI 2001 Edition through the 2003 Addenda, for the Second 10-year interval at Watts Bar Unit 1. Specifically, Examination Category B-D, Full Penetration Welded Nozzles in Vessels - Inspection Program B, Items No. B3.90, Examination Requirements/Figures IWB-2500-7, requiring the examination coverage of 1/2t beyond the edge of the weld, change to 1/2 beyond the edge of the weld.
EXECUTIVE
SUMMARY
Watts Bar Unit 1 ISI program requirements for the examination volumes of the Class 1 reactor vessel pressure-retaining nozzle-to-vessel welds (Examination Category B-D, Items No. B3.90 -
Inspection Program B) are shown in Figures IWB-2500-7(a) through (b) of the ASME Section XI Code 2001 Edition, 2003 Addenda.
These figures require that licensees perform examinations of the weld volumes and the adjacent vessel or nozzle base metal material regions equivalent to one-half (1/2) the vessel shell thickness beyond the end of the welds boundary.
The extent of the examination volume for a given nozzle-to-vessel weld dictates the exam time and the amount of radiation dose exposure of the personnel involved. Historical improvements in the ultrasonic examination techniques and the qualifications of the examiners in accordance with the Section XI Appendix VIII has reduced the necessity of having the nozzle-to-vessel weld exam volumes be as large as currently required in Figures IWB-2500-7 (a) through (d). TVA proposes to reduce the required examination volumes extent (next to the widest part of the weld) from one-half of the shell thickness to one-half (1/2) inch beyond the boundary of the weld.
The reduction of the exam volume in lieu of the current ASME Section XI Code required examination volumes will result in a reduction of examination time and the associated examination personnel radiation exposure while maintaining an acceptable level of quality and safety. Except for the proposed reduced
E1-2 examination volumes, TVA will continue to perform the volumetric examinations in accordance with the other specific aspects and requirements of the ASME Code for these exams. Accordingly, pursuant to 10 CFR 50.55a(a)(3)(i), relief is requested to use the reduced examination volumes in lieu of the requirements shown in ASME Section XI Figures, IWB-2500-7 (a) through (d).
SYSTEM/COMPONENT(S) FOR WHICH RELIEF IS REQUESTED:
ASME Class 1, Reactor Pressure Vessel (RPV) Pressure-retaining Nozzle-To-Vessel welds.
ASME SECTION XI CODE EDITION/ADDENDA:
The applicable ASME Section XI Code of Record for the second Watts Bar Unit 1 inservice inspection interval is the 2001 Edition with addenda through the 2003 Addenda with amendments specified in 10CFR50.55a.
CODE REQUIREMENTS:
In accordance with the Watts Bar Unit 1 ISI Program, the ASME Section XI Code-of-Record rules for Inservice Inspection of Nuclear Power Plant Components; the requirements for nozzle-to-vessel weld examination volume shown in Section XI, Subsection IWB, Examination Category B-D Full Penetration Welds of Nozzles in Vessels - Inspection Program B, Code Item Number B3.90, with Figures IWB-2500-7(a) and IWB-2500-7(b) are applicable.
REQUIREMENT FROM WHICH RELIEF IS REQUESTED:
The specific Code requirement from which relief is requested is the requirement to perform the volumetric examination of the indicated nozzle-to-vessel welds in accordance with the examination volume requirements shown in ASME Section XI Subsection IWB, Figures IWB-2500-7(a) and (b). Pursuant to 10 CFR 50.55a(a)(3)(i), relief is requested to perform the Code examination on a reduced volume of 1/2 inch beyond the widest part of the boundary of the deposited weld material in lieu of the requirements of ASME Section XI Figures IWB-2500-7(a) and IWB-2500-7(b). When performing the examinations of nozzle-to-vessel welds, TVA will comply with the special requirements imposed in 10 CFR 50.55a(b)(2)(xv)(K)(1) and 10 CFR 50.55a(b)(2)(xv)(K)(2).
These requirements dictate that the examination scanning processes must also be performed in such a manner to detect flaws oriented axially with the nozzle.
E1-3 BASIS FOR RELIEF:
Inservice examination of selected Reactor Pressure Vessel (RPV) nozzle-to-vessel welds at TVA nuclear plants is currently performed in accordance with the requirements of 10 CFR 50.55a, plant Technical Requirements, and the associated ASME Section XI ISI Program Codes-of-Record Editions and Addenda of the ASME Boiler and Pressure Vessel Code,Section XI, Rules for Inservice Inspection of Nuclear Power Plant Components. The 2001 Edition through the 2003 Addenda of ASME Section XI invokes the examination volume requirements of Figures IWB-2500-7(a) and IWB-2500-7(b).
Under the Appendix VIII procedures the required examinations will be performed using procedures which provide for a rigorous methodology for ultrasonic examinations.
JUSTIFICATION FOR GRANTING RELIEF:
The examination volume required by IWB-2500-7(a) and (b) for the reactor vessel pressure retaining nozzle-to-vessel welds extends far beyond the weld and the heat effected zones into the base metal, and is unnecessarily large. This extends examination time significantly, increases the radiation exposure of exam support personnel, and results in no net increase in safety; as the additional area being examined is a base-metal region of the reactor vessel shell or nozzle wall areas where industry experience has shown service-induced cracks are not prone to occurring. In addition, these regions have been extensively examined during the fabrication and installation periods before the vessels were put in service and during the inservice examinations already performed.
The reduction of UT examination volumes adjacent to the widest part of the weld from one-half of the vessel wall thickness to one-half (1/2) inch beyond the weld boundary eliminates base metal material volume to be examined that was extensively examined during construction and preservice examinations, where applicable; and, eliminates areas which are not located in the high-stressed areas of the weld geometry. The high-stressed areas of the various nozzle-to-vessel weld configurations and areas where flaws are most likely to initiate are adequately addressed and contained in the examination volume defined by the area 1/2 inch beyond the weld boundary.
In addition, use of these proposed examination boundaries will be conducted in conjunction with TVAs programmatic implementation of the mandated use of ASME Section XI, Appendix VIII. Watts Bar Unit 1 will implement these requirements in accordance with the requirements shown in ASME Section XI Appendix VIII as required in paragraphs 10 CFR 50.55a(b)(2)(xiv), (xv), (xvi) and (xxiv);
and in 10 CFR 50.55a(g)(6)(ii)(C). These procedures will ensure
E1-4 that the performance-based UT methodologies used and the techniques will be qualified and examination personnel will be certified by a performance demonstration.
The use of the reduced examination volumes in lieu of the identified ASME Section XI referenced requirements could reduce on-vessel examination time and a reduction of examination support personnel radiation exposure. The personnel radiation exposure is dependent upon the choice of RPV examination equipment (i.e.
automated versus manual) and by the degree of plant RPV contamination and/or decontamination conducted prior to the exam.
In conclusion, use of the reduced examination volume requirements in conjunction with the application of the Appendix VIII implementing PDI program will provide sufficient assurance that RPV nozzle-to-vessel welds have remained free of service induced flaws or identify such flaws prior to failure. The application of the PDI techniques will enhance quality of the UT examinations and ensure plant safety and pressure boundary reliability.
Therefore, the proposed alternative provides for an acceptable level of quality and safety and, pursuant to 10 CFR 50.55a(a)(3)(i), relief to use the reduced examination volumes may be granted.
ALTERNATIVE EXAMINATIONS:
TVA will perform the examinations of the RPV nozzle-to-vessel welds as follows:
Ultrasonic examinations of the RPV nozzle-to-vessel welds in accordance with the requirements of ASME Section XI Appendix VIII with examination volumes to include regions up to 1/2 inch beyond the weld boundary.
In accordance with the requirements shown in ASME Section XI Appendix VIII of the 2001 Edition, as amended by the Final Rule and as required in paragraphs 10 CFR 50.55a(b)(2)(xiv), (xv), and (xvi); and in 10 CFR 50.55a(g)(6)(ii)(C) through the use of the EPRI PDI program document, PDI Program Description, as allowed in the discussion on the Final Rule published in the Federal Register.
Continued periodic system pressure tests of the RPV per ASME Section XI requirements of Table IWB-2500-1, for Category B-P items.
IMPLEMENTATION SCHEDULE:
Upon approval by the NRC Staff, TVA will implement the provisions of this request during the Second Ten-Year Inservice Inspection
E1-5 Interval for Watts Bar Unit 1 and conduct the next scheduled RPV nozzle-to-vessel weld examinations accordingly.
PRECEDENTS Similar relief has been submitted by TVA for Browns Ferry Units 2 and 3, Sequoyah Units 1 and 2, and Watts Bar Unit 1 power plants by letters dated February 23, July 9, and August 23, 2001. TVAs request for relief was subsequently approved by NRC letter dated September 19, 2001.

SECTION XI INSERVICE INSPECTION (ISI) PROGRAM SECOND TEN-YEAR INSERVICE INSPECTION INTERVAL REQUEST FOR RELIEF PDI-4 TVA requests approval for an alternative to ASME Section XI, paragraph IWA-2232 of the ASME Section XI 2001 Edition through the 2003 Addenda, for the second 10-year interval at Watts Bar Nuclear (WBN) Unit 1. Specifically, for use of Appendix VIII and Performance Demonstration Initiative (PDI) methodologies for performance of the ultrasonic examination of reactor pressure vessel shell-to-flange welds in lieu of the requirement of Appendix I and the associated Article 4, ASME Section V EXECUTIVE
SUMMARY
In accordance with 10 CFR 50.55a(a)(3)(i), TVA is requesting relief from the specific requirements of performing the volumetric examination of the reactor pressure vessel (RPV) circumferential shell-to-flange weld at Watts Bar Unit 1 in accordance with the requirement of Appendix I of Section XI. In addition, the guidance of Regulatory Guide (RG) 1.150, Ultrasonic Testing of Reactor Vessel Welds During Preservice and Inservice Examinations, Revision 1, was historically applied.
In lieu of the requirements of Appendix I and its associated sub-requirements of Article 4 of Section V, WBN Unit 1 will use the techniques, personnel, and equipment qualified to meet the requirements of ASME Section XI Appendix VIII, Supplements 4 and 6 of the 2001 Edition through the 2003 Addenda, as administered by the Electric Power Research Institutes (EPRI)
Performance Demonstration Initiative (PDI) processes. WBN plans to use the proposed alternative during the next regularly scheduled RPV examinations to be performed at or near the end of the Second 10-year ISI Program interval. This proposed alternative represents the best available methodology in qualification of equipment and personnel performing ultrasonic examinations and uses an examination process that has provided and will provide the highest practical quality and greatest amount of coverage for the performance of the shell-to-flange weld examinations. As such, the proposed alternative methodology provides an acceptable level of quality and safety. In addition, the approval of this relief results in savings in the cost of performing the examinations, with not having to incorporate the use of two different sets of examination equipment, and also
E2-2 results in lower personnel radiation exposure from not having to use a different methodology for the shell-to-flange weld.
Note that this request for relief is similar to the request granted during the First 10 Year Interval submitted initially in a letter from TVA to the NRC, dated February 23, 2005 and approved by the Staff in a letter dated August 2, 2005 (Ref.
SYSTEM/COMPONENT(S) FOR WHICH RELIEF IS REQUESTED:
ASME Code Class 1 Reactor Pressure Vessel (RPV) Upper Vessel Shell-to-Flange Welds, Table IWB-2500-1 Category B-A, Item Number B1.30.
APPLICABLE CODE EDITION AND ADDENDA FOR THE GIVEN EXAM The applicable ASME Section XI Code Edition and Addenda of Record for Watts Bar Unit 1 second inservice inspection interval is the 2001 Edition with addenda through the 2003 Addenda with applicable amendments from 10CFR50.55a.
CODE REQUIREMENTS FROM WHICH RELIEF IS REQUESTED:
In accordance with ASME Section XI, paragraph IWA-2232, Ultrasonic examinations shall be conducted in accordance with Appendix I.
Further, in accordance with Appendix I, paragraph I-2110(b)
Ultrasonic examination of reactor vessel-to-flange welds, closure head-to-flange welds, and integral attachment welds shall be conducted in accordance with Article 4 of Section V, except that alternative examination beam angles may be used.
RELIEF REQUESTED:
Pursuant to 10 CFR 50.55a(a)(3)(i), TVA requests relief from performing the designated vessel shell-to-flange weld examination in accordance with the requirements of ASME Section XI, paragraph IWA-2232, Appendix I, and the associated Article 4 of Section V methodology in accordance with paragraph I-2110(b).
BASIS FOR RELIEF:
In accordance with ASME Section XI, Subarticle IWA-2232, TVA is required to perform ultrasonic examinations (UT) of the RPV upper
E2-3 shell-to-flange welds using Section XI, Appendix I, which in turn requires the use of the NDE methodologies and processes of ASME Section V, Article 4. In addition, the guidance of RG-1.150, Revision 1, was historically applied. The above listed welds are the only circumferential shell welds in the RPV that are not examined in accordance with the requirements of ASME Section XI, Appendix VIII, as mandated in 10 CFR 50.55a with the issuance of the rule change shown in the Federal Register Notice 64 FR 51370, dated September 22, 1999. This rule change mandated the use of ASME Section XI, Appendix VIII, Supplements 4 and 6 for the conduct of RPV examinations. It has been stated in EPRI PDI coordination meetings between the PDI committee members and the NRC Staff representatives that the NRC Staff expectations are that licensees should submit requests for relief to use the more technically advanced Appendix VIII/PDI processes for the shell-to-flange weld exams, in lieu of the Section XI Appendix I and its associated Section V, Article 4 processes.
PROPOSED ALTERNATIVES TVA proposes to use the procedures, personnel, and equipment qualified to meet the requirements of ASME Section XI Appendix VIII, Supplements 4 and 6 as administered by the Electric Power Research Institutes (EPRI) Performance Demonstration Initiative (PDI), to conduct the required vessel-to-flange weld examinations.
JUSTIFICATION FOR GRANTING RELIEF:
ASME Section V, Article 4, describes the required techniques to be used for the UT of welds in ferretic pressure vessels with wall thicknesses greater than 2 inches. The techniques were first published in ASME Section V in the 1974 Edition, summer 1975 Addenda. The calibration techniques, recording criteria and flaw sizing methods are based upon the use of a distance-amplitude-correction curve (DAC) derived from machined reflectors in a basic calibration block. UT performed in accordance with Section V, Article 4, used recording thresholds of 50 percent DAC for the outer 80 percent of the required examination volume and 20 percent DAC from the clad/base metal interface to the inner 20 percent margin of the examination volume. Indications detected in the designated exam volume portions, with amplitudes below these thresholds, were therefore not required to be recorded.
Use of the Appendix VIII/PDI processes would enhance the quality of the examination results reported because the detection sensitivity is more conservative and the procedure requires the examiner to evaluate all indications determined to be flaws regardless of their associated amplitude. The recording thresholds in Section V, Article 4, requirements and in the guidelines of RG-1.150, Revision 1, are generic and somewhat
E2-4 arbitrary and do not take into consideration such factors as flaw orientation, which can influence the amplitude of UT responses.
The EPRI Report NP-6273, Accuracy of Ultrasonic Flaw Sizing Techniques for Reactor Pressure Vessels, dated March 1989, established that UT flaw sizing techniques based on tip diffraction are the most accurate. The qualified prescriptive-based UT procedures of ASME Section V, Article 4 have been applied in a controlled process with mockups of RPVs which contained real flaws and the results statistically analyzed according to the screening criteria in Appendix VIII of ASME Section XI. The results show that the procedures in Section V, Article 4, are less effective in detecting flaws than procedures qualified in accordance with Appendix VIII as administered by the PDI processes. Appendix VIII/PDI qualification procedures use the tip diffraction techniques for flaw sizing. The proposed alternative Appendix VIII/PDI UT methodology uses analysis tools based upon echo dynamic motion and tip diffraction criteria which has been validated, and is considered more accurate than the Section V, Article 4 processes.
UT performed in accordance with the Section V, Article 4 processes requires the use of beam angles of 0o, 45o, 60o, and 70o with recording criteria that precipitates equipment changes.
Having to perform these process changes is time consuming and results in increased radiation exposure for the examination personnel. Having to comply with the specific ASME Section XI, Appendix I requirements for the RPV circumferential shell-to-flange weld, when the data is obtained using a less technically advanced process, results in an examination that does not provide a compensating increase in quality and safety for the higher costs and personnel exposures involved.
For future RPV shell-to-flange weld examinations TVA does not anticipate any less coverage than the required minimum of 90 percent of coverage. However, if any such limitations are encountered during the conduct of the examinations, separate individual relief requests will be submitted, as needed.
Procedures, equipment, and personnel qualified through the Appendix VIII, Supplements 4 and 6 PDI programs have shown to have a high probability of detection of flaws and are generally considered superior to the techniques employed earlier for RPV examinations. This results in increased reliability of RPV inspections and conditions where an acceptable level of quality and safety is provided with the proposed alternative methodologies. Accordingly, approval of this alternative evaluation process is requested pursuant to 10 CFR 50.55a(a)(3)(i).
IMPLEMENTATION SCHEDULE AND DURATION:
E2-5 Upon approval by the NRC staff, TVA will implement the provisions of this request during the second ten-year inservice inspection interval for Watts Bar Unit 1.
PRECEDENTS Note that this request for relief is similar to the request granted during the first 10-year interval submitted initially in a letter from TVA to the NRC, dated February 23, 2005 and approved by the Staff in a letter dated August 2, 2005 (Ref. ML051730487).

SECTION XI INSERVICE INSPECTION (ISI) PROGRAM SECOND TEN-YEAR INSERVICE INSPECTION INTERVAL SNUBBER REQUEST FOR RELIEF SNBR-1 Summary: Pursuant to 10CFR50.55a(a)(3)(i), TVA is requesting relief from the identified ASME Section XI requirements related to examination and testing of snubbers. TVA proposes to continue to use the examination and testing plans currently defined in the Technical Requirements Manual (TR 3.7.3). The current Technical Requirements Manual requirements have been promulgated and approved by NRC, while ASME Section XI imposes overlapping requirements which do not enhance the quality or safety of the subject snubber examination and testing.
Components: Component/piping snubbers Code Class: 1, 2 and 3 Examination Category: F-A (snubber examination only, N/A for snubber testing)
Item Number: F1.10, F1.20, F1.30, and F1.40 (snubber examination only, N/A for snubber testing)
Code Requirement: ASME Boiler and Pressure Vessel Code,Section XI, 2001 Edition, 2003 Addenda, Subarticles:
IWA-4530(b), preservice inspection and testing IWF-5200(a) and (b), preservice examinations and tests IWF-5300(a) and (b) inservice examination and testing in accordance with the first Addenda to ASME/ANSI OM-1987, Part 4, with OMa-1988.
IWF-5400 Repairs and Replacements of snubbers shall be in accordance with the first Addenda to ASME/ANSI OM-1987, Part 4, with OMa-1988.
IWA-6210(c), records and reports
E3-2 IWA-6230 requires inservice inspection summary reports for snubbers to be filed with the regulatory authority.
IWA-6240, summary report submittal IWA-2110 requires Authorized Nuclear Inservice Inspector (ANII) involvement for snubber examination and testing Code Requirement From Which Relief is Requested: In accordance with 10CFR50.55a(a)(3)(i), relief is requested from the ASME Section XI 2001 Edition, 2003 addenda, requirement for preservice and inservice examinations and tests for snubbers, and repair/replacement examinations and tests of snubbers:
IWA-4530(b) requires preservice inspection and testing to be in accordance with IWF-5200 following repair/replacement of a snubber.
IWF-5200(a) and (b) requires preservice examinations and tests in accordance with ASME/ANSI OM Part 4, 1987 Edition, OMa-1988 Addenda, using the VT-3 visual examination method in accordance with IWA-2213.
IWF-5300(a) and (b) requires inservice examinations and tests in accordance with ASME/ANSI OM Part 4, 1987 Edition, OMa-1988 Addenda, using the VT-3 visual examination method in accordance with IWA-2213.
IWF-5400 references IWF-5200 for snubber examination and test requirements following repair or replacement.
IWA-6210(c) requires the preparation of preservice and inservice inspection summary reports for Class 1 and 2 snubbers.
IWA-6230 requires the preparation of an inservice inspection summary report (snubbers) after each refueling outage.
IWA-6240, requires the submittal of summary reports (snubbers) to the regulatory authority.
IWA-2110, Duties of the Inspector (for involvement for snubber examination and testing).
Basis For Relief: Watts Bar Nuclear Plant (WBN) Unit 1 is required to update to the 2001 Edition, 2003 Addenda, of ASME Section XI for WBNs second ten-year ISI inspection interval. ASME Section XI Class 1, 2 and 3 equivalent snubbers are examined and tested in accordance with Watts Bar Nuclear (WBN) Plant Technical Requirements Manual (TRM), TR 3.7.3 which was prepared in accordance with the guidance given by NRC in Generic Letter 90-09.
The scope for snubbers examined and tested in accordance with TR
E3-3 3.7.3 is not limited by line size or other applicable code exemptions and includes a numerically greater population of snubbers than the Section XI program. Examination and testing of the snubbers in accordance with both ASME Section XI and the plant TRM would result in a duplication of effort utilizing different standards and require the preparation of a separate program and associated procedures. This would result in additional cost and unnecessary radiological exposure. In addition, the personnel performing snubber visual examinations would also be required to be certified in accordance with the American Society of Nondestructive Testing (ASNT) SNT-TC-1A, Personnel Qualification and Certification in Nondestructive Testing, and ASME/ASNT-CP-189, which is an additional certification as compared to the task training qualification required to perform the TRM required examinations and testing of snubbers. The existing TRM program for examination and testing of snubbers was promulgated and accepted by NRC.
The implementation of OM-1987, Part 4, with OMa-1988 Addenda would require WBN to initiate a snubber examination and testing program which would increase the manpower and potentially the radiation exposure to implement, when compared to the existing TRM mandated snubber program, without a compensating increase in the level of quality and safety.
Alternate Examinations: The WBN TRM, TR 3.7.3, requirements will be utilized for the examination and testing of snubbers for preservice, inservice, and repair/replacement activities. The procedures utilized for these examinations are: 1-TRI-0-5, Snubber Visual Inspection; 1-TRI-0-7, Snubber Functional Testing (Mechanical Snubbers); and 1-TRI-0-8, Snubber Functional Testing (Paul Monroe Snubbers). The snubber visual examinations include the pin-to-pin area inclusive of applicable snubbers.
Testing of repaired and replaced snubbers will be performed in accordance with TR 3.7.3, Note 2.
A comprehensive list of snubbers is maintained in Technical Instruction TI-203, Snubber Program. Other related procedures include: Maintenance Instruction (MI) 0.044, Removal and Reinstallation of Mechanical Snubbers and MI-0.05 Fluid Sampling and Maintenance for Paul Monroe Snubbers.
Snubber examination and testing data will be maintained in accordance with the requirements of TR 3.7.3, procedure SPP-3.1, Corrective Action Program, and implementing procedures 1-TRI-0-5, 1-TRI-0-7, and 1-TRI-0-8.
The areas inclusive of the pins back to building structure and to the component/piping being supported will remain in the ASME Section XI examination boundary and IWF-5200(c) and IWF-5300(c)
E3-4 will be met through ASME Section XI preservice examination and/or scheduled inservice examinations, as applicable, for the second interval.
Justification For The Granting Of Relief: The current program, as defined by TR 3.7.3, provides for a level of quality and safety equal to that provided by OM Code 1987, Part 4, with OMa-1988 Addenda (referenced by ASME Section XI, 2001 Edition, 2003 Addenda).
Examination, testing, repair and replacement of snubbers are currently performed in accordance with TR 3.7.3, which utilizes the guidance provided by NRC in Generic Letter 90-09. The OM Code referenced by ASME Section XI has a different basis for examination (failure mode groups) and testing plans (10 percent, 37, or 55).
It is impractical to implement both plans because of the resulting duplication of examination and testing efforts and different requirements for snubber quantities subject to examination or test, actually examined and/or tested, and sample expansion requirements.
This would result in additional cost and unnecessary radiological exposure. The existing TRM program for examination and testing of snubbers has been promulgated and accepted by NRC. The differences in the two programs could create confusion when selecting test samples, applying acceptance criteria, corrective actions, and examination schedules for failed snubbers. This situation could increase the possibility of applying the wrong action, thus creating a nonconformance, an inoperability or even a violation of a TRM requirement.
To eliminate any misinterpretation or confusion in administering overlapping requirements for snubbers, and to remove the possibility of applying contradicting requirements to the same snubber(s), WBN proposes to examine and test snubbers in accordance with WBN TR 3.7.3.
Subarticle IWF-5400 provides the requirements for repair and replacement of snubbers to be in accordance with OM Code 1987, Part 4, with OMa-1988 Addenda. Specifically, OM Code 1987, Part 4, with OMa-1988 Addenda, Sections 1.5.6, Snubber Maintenance or Repair and 1.5.7, Snubber Modification and Replacement require repaired and replaced snubbers to meet the visual examination requirements of Paragraph 2.3.1.2 and the operability test requirements of Paragraph 3.2.11. Section 1.5.6 also requires an evaluation of the maintenance or repair activity and Section 1.5.7 requires a suitability evaluation on the replacement/modified snubber. TR 3.7.3 (Note 2) requires replacement snubbers and snubbers which have repairs which might affect the functional test results to be tested to meet the functional test criteria prior to installation.
Procedure 1-TRI-0-5 provides visual examination criteria for installation of a snubber after repair or replacement. The ASME
E3-5 Section XI repair/replacement program at WBN documents the suitability of repairs/replacements per IWA-4160.
ASME Section XI VT-3 certification required by personnel performing snubber visual examinations is an additional certification as compared with the TRM program training qualifications. Personnel performing the TRM required visual examinations are process qualified to perform the examinations and testing required by the TRM and implemented by the referenced procedures. This training currently includes a visual test associated with face mask fit and specific training on the acceptance criteria associated with procedure 1-TRI-0-5. Additional visual acuity verification for personnel performing snubber visual examinations will include visual acuity requirements that meet ASME Section XI. The training and documentation of personnel to the visual acceptance criteria, specified in the TRM implementing procedures, provides an acceptable level of quality and safety.
Because relief is sought from the ASME Section XI snubber examination and test requirements, there will be no ASME Section XI snubber examination and test activities to require ANII involvement. The WBN TRM snubber program does not require the use of an ANII for examination and test requirements. The ANII will not be involved in the TRM required visual examination or testing activities performed in lieu of the ASME Code requirements. A snubber program manager provides oversight of the TRM snubber program implementation for both visual examination and functional testing. This oversight includes both review and evaluation of visual examination and functional testing data to ensure TRM requirements are met. The snubber program manager provides an acceptable level of quality and safety without ANII involvement in those activities. ANII involvement in other repair and replacement snubber activities, as required by IWA-2110(g) and (h) and implemented by the WBN ASME Section XI Repair and Replacement Program will be maintained.
Subarticle IWA-6230 and OM Code 1987, Part 4, with OMa-1988 Addenda, Sections 2.3 and 3.3 provide requirements for ASME Section XI inservice examination and test documentation for snubbers and a summary report of examinations and testing. Under the alternate requirements for snubbers, there will be no ASME Section XI inservice examination and testing to document in a summary report.
TR 3.7.3 is implemented by implementing procedures / instructions 1-TRI-0-5, 1-TRI-0-7, and 1-TRI-0-8. These instructions, written and approved in accordance with the TVA Nuclear Quality Assurance Program, include data sheets for documenting the visual examination and functional test data and results, and provide for documentation of nonconforming results and evaluation of those results. The completed data sheets are QA records and are controlled and maintained in accordance with the WBN QA records program. These records are available onsite for review and inspection. The QA
E3-6 records documenting snubber visual examinations and functional tests provide an acceptable level of quality and safety when compared to the requirements of ASME Section XI and OM-1987, Part 4, with OMa-1988 Addenda.
Based on the justification provided, the WBN method of examination and testing of snubbers, in accordance with TR 3.7.3 will provide an acceptable level of quality and safety. Therefore, pursuant to 10CFR50.55a(a)(3)(i), TVA requests that relief be granted from the 2001 Edition, 2003 addenda of ASME Section XI Code requirements related to inservice examination and testing for snubbers.
See Attachment for a table that compares OM Code requirements and TRM requirements.
Implementation Schedule: TR 3.7.3 will be implemented during the second ten-year ASME Section XI inspection interval for snubber examination and testing in lieu of the ASME Code Section XI requirements listed above.

1.0 INTRODUCTION
1.1 Purpose In accordance with Title 10 Code of Federal Regulations (CFR) Part 50.55a(g), this program implements the Watts Bar Nuclear Plant (WBN) Unit 1 Technical Surveillance Requirement 3.4.5.2 and fulfills the requirements of SPP-9.1, Part A, ASME Section XI Inservice Inspection and Augmented Nondestructive Examinations. This program is organized to comply with the inservice inspection (ISI) nondestructive examination (NDE) requirements of the 2001 Edition, 2003 Addenda Edition of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section XI, Division 1, Articles 1000, 2000, 3000, and 6000.
This ISI/NDE Program is an administrative Technical Requirement Instruction (TRI) employed to obtain data via NDE of ASME Section XI Code Class 1, 2, and 3 equivalent components to determine acceptance of components for continued service during operation and if a flaw is an isolated case or of a generic nature. It shall serve as TVA's ISI/NDE plan and schedule in accordance with the requirements of IWA-1400 for the WBN Unit 1 second ISI interval.
This ISI/NDE Program reflects the built-in limitations of the original plant design, geometry, construction, component materials, and the current technology or state-of-the-art nondestructive examination techniques. It specifies the number of components to be examined, the examination methods to be used and provides schedule tables from which specific items are scheduled for examination. These items are described and detailed in ISI scan plans.
1.2 Scope (Applicability)
This program outlines details for planning and implementing the second ISI/NDE inspection interval for ASME Section XI Code Class 1, 2, and 3 equivalent components at WBN Unit 1 in accordance with IWA-2432, Inspection Program B.

B.
Perform a surface examination of all exposed surfaces and complete ultrasonic examination at approximately 10-year intervals during the plant shutdown coinciding with the ISI schedule as required by Section XI.
Responsible Organization: Component Engineering The augmented examination requirements of the reactor coolant pump flywheel are included in Regulatory Position C.4.b of Regulatory Guide 1.14, Revision 1; (1) an in-place ultrasonic examination of the areas of higher stress concentration at the bore and keyway at approximately 3-year intervals during the refueling or maintenance shutdown coinciding with the ISI schedule as required by Section XI of the ASME Code, and (2) a surface examination of all exposed surfaces (exposed areas are considered as those areas accessible for examination without having to remove the flywheel from the housing) and complete ultrasonic examination at approximately 10-year intervals during the plant shutdown coinciding with the ISI schedule as required by Section XI of the ASME Code. This examination is performed in accordance with WBN Technical Surveillance Requirement 3.4.5.1.
This augmented examination does not require a special report unless the examination reveals a flaw. The acceptance criteria should conform to the recommendations of Regulatory Position C.2.F in Regulatory Guide 1.14. If the examination and evaluation indicate an increase in flaw size or growth rate greater than predicted for the service life of the flywheel, the results of the examination and evaluation should be submitted to the NRC for evaluation. Refer to Regulatory Guide 1.14 for information to be included. The examination results shall be included in the augmented section of the ISI Summary Report.
The flywheel consists of 2 plates, approximately 5 inches and 8 inches thick, bolted together. Each plate is fabricated from vacuum degassed A-533, GR. B, Class 1, steel.

Augmented Examinations 4.0 Examination of Alloy 600 Welds (continued)
Boric acid leaks on and around the reactor pressure vessel (RPV) and alloy 600 nozzle cracking issues within the PWR nuclear industry has lead to both NRC mandated examinations and the need to evaluate performance of additional examinations beyond the ASME Section XI requirements on the RPV head, RPV bottom head and pressurizer nozzles. The requirements for Alloy 600 issues are maintained in Business Practice BP-257, Integrated Material Issues Management Plan. This augmented examination section briefly describes those examinations and inspections that should be coordinated and scheduled with the standard ISI examinations performed by Inspection Services Organizations each refueling outage.
A.
RPV Head In response to leaks and nozzle cracking in PWR plants, the NRC issued an Order on February 11, 2003 entitled, Issuance of Order Establishing Interim Inspection Requirements for Reactor Pressure Vessel Heads at Pressurized Water Reactors. The Order requires specific inspection of the RPV head and associated penetration nozzles. A revised Order was issued February 20, 2004 which addresses revisions to bare metal visual inspection, penetration nozzle inspection coverage, flexibility in combination of non-destructive examination methods, flaw evaluation, and requirements for plants which have replaced their RPV head. WBN is classified in the Low susceptibility category to PWSCC-related degradation in accordance with the Order. The following examinations will be performed to meet the Orders inspection requirements defined in Section C.3:
- 1.
A bare metal visual examination of 100% of the RPV head surface (including 3600 around each RPV head penetration nozzle) was performed beginning in the cycle 5 refueling outage. Thereafter, the inspection shall be performed at least every third refueling outage or every five years, whichever occurs first. This inspection will be performed in accordance with NDE procedure N-VT-17, Visual Examination for Leakage of PWR Reactor Head Penetrations, by a VT-2 certified inspector. Any questionable indications or evidence of boron will be inspected by a Metallurgical Engineer.
- 2.
Inspection of the head penetration nozzles shall be performed as described in either 2a, 2b or 2c. Either of these inspections must be completed at least once before February 10, 2008 and thereafter at least every four refueling outages or every seven years, whichever occurs first. The inspection requirements are either:

The examination will be performed in accordance with NDE procedure N-VT-19, Visual Inspection of Alloy 600/82/182 Pressure Boundary Components. The inspections shall begin in the cycle 6 refueling outage. It is permissible to substitute a PDI qualified ultrasonic examination (ASME Section XI, Appendix VIII) of the subject weld in lieu of the visual examination provided greater than 90% coverage can be obtained.
The inspection results shall be forwarded to Site Mechanical/Nuclear Engineering. The results shall be included in the augmented section of the ISI Summary Report.

Augmented Examinations 5.0 Examination of Clad Areas in Reactor Vessel Inlet Nozzles and Accumulator Tank # 3 (continued)
Prior to plant start-up, one area in Loop 2 inlet nozzle and two areas in Loop 3 inlet nozzle had the stainless steel cladding removed to validate flaw depth sizing. After cladding removal and validation of the flaw depth sizing, a metallurgical evaluation recommended the three areas without cladding be left in an unclad condition. A summary of the information concerning this issue is discussed in the July 30, 2003 letter to the NRC (reference T04 030730 825).
During the remote visual portion of the reactor vessel 10-year ISI inspection, specific attention will be given to the unclad areas in the Loops 2 and 3 inlet nozzles for any evidence of wall deterioration. These areas should be specifically noted in the scope of inspection with the contract inspector. The examination results will not require a special report but will be included as part of the reactor vessel 10-year inspection report.
B.
Accumulator Tank #3 Flaw indications in the cladding of the safety injection accumulator tank #3 were identified and documented in PER WBPER920252 dated November 2, 1992.
Attempts to repair the indications were made by removing the cladding containing the indications and replacing it with weld metal. However, excavation to remove the indications and shrinkage stresses from welding continually generated new indications in the sensitized cladding in adjacent areas previously free of indications. After a review of this information as documented in PER 03-0129850-000, mechanical engineering has recommended the areas described below be examined to determine that the vessel wall is not deteriorating as a result of the cladding cracks.
Beginning in the cycle 6 refueling outage and every other refueling outage thereafter, an ultrasonic examination shall be performed from the outside of accumulator tank #3 at the areas of the bottom head described below (reference vendor drawing 1097E08):
All inspection areas are on the orange peel plate section with the 3/4 sample nozzle. Area a is accessed outside the tank support ring and remaining areas accessed under the support ring.
