1. TVA letter to NRG, "Watts Bar Nuclear Plant (WBN) Unit 2 -American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Transition

-Revised Commitment," dated September 1, 2011 (ML 102930299)

2. TVA letter to NRG, "Watts Bar Nuclear Plant (WBN) Unit 2 -American Society of Mechanical Engineers (ASME)Section XI Request for Relief WBN-2/PSl-1," dated October 11, 2010 (ML 11306A022)

3. TVA letter to NRC, "Watts Bar Nuclear Plant, Unit 2 -American Society of Mechanical Engineers,Section XI, Preservice Inspection . Summary Report," dated August 9, 2016 In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 50.55a, "Codes and Standards," paragraphs (g)(5)(iii) and (g)(6), Tennessee Valley Authority (TVA) is submitting a revised relief request for Nuclear Regulatory Commission (NRC) approval for the Watts Bar Nuclear Plant (WBN) Unit 2 Preservice Inspection (PSI) period. In accordance with Reference 1, the WBN Unit 2 PSI period ended with initial turbine-generator synchronization following initial criticality on June 3, 2016.

U.S. Nuclear Regulatory Commission CNL-16-135 Page 2 October 5, 2016 Enclosure 1 provides relief request WBN-2/PSl-1, Revision 1 that requests relief from the requirements of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code,Section XI, "Rules for lnservice Inspection of Nuclear Power Plant Components," Subarticle IWB-2200, "Preservice Examination," ASME Code Class 1, Table IWB-2500-1, and ASME Code Class 2, Table IWC-2500-1, which require either a volumetric examination of essentially 100 percent(%)

of the weld volume or a surface examination of essentially 100% of the weld area. The specific item numbers from Tables IWB-2500-1 and IWC-2500-1, for which relief is requested, are shown in Table 1 of Enclosure

1. The ASME B&PV Code,Section XI, 2001 Edition through 2003 Addenda was the code of record for the WBN Unit 2 PSI period. This revised relief request supersedes the one submitted by TVA for WBN Unit 2 in Reference

2. Attachment 1 to Enclosure 1 provides a compact disc (CD) containing the drawings that support the relief request. The definition of "essentially 100%" is provided by NRC Information Notice 98-42, "Implementation of 10 CFR 50.55a(g) lnservice Inspection Requirements," and Code Case N-460, "Alternative Examination Coverage for Class 1 and Class 2 Welds,Section XI, Division 1," which requires examination coverage of "more than 90 percent of the specified examination volume" in lieu of "essentially 100%." 1 O CFR 50.55a(g)(6) authorizes the NRC to grant relief for determinations under 10 CFR 50.55a(g)(5) when Code requirements are impractical.

TVA is requesting relief on the basis that the Code-required "essentially 100%" examination coverage is impractical due to physical obstructions and limitations imposed by design, geometry, or physical obstructions for the welds and associated components listed in Table 1 to Enclosure

1. As an alternative, TVA has invoked ASME Section XI Code Case N-460, which states: "when the entire examination volume or area cannot be examined due to interference by another component or part geometry, a reduction in examination coverage on any Class 1 or Class 2 weld may be accepted provided the reduction in coverage for that weld is less than 10%." Therefore, TV A is requesting relief only for those welds that were inspected and received Code coverage of 90% or less. Examination coverage of greater than 90% was not achieved for the welds listed in the proposed relief request and the applicable coverage percentage is specified in the relief request for each weld (Table 1 to Enclosure 1). The examination coverage achieved for the subject welds in conjunction with acceptable construction code examinations provides reasonable assurance that unallowable flaws do not exist in the subject component welds and that the welds are acceptable for service. Thus, an acceptable level of quality and safety was achieved and public health and safety was not endangered by allowing the proposed alternative examination coverage in lieu of the Code requirement.

The nondestructive examination (NOE) reports listed in Table 1 to Enclosure 1 are available for NRC review.

U.S. Nuclear Regulatory Commission CNL-16-135 Page 3 October 5, 2016 Enclosure 2 to this submittal contains Revision 11 to the WBN Unit 2 PSI Program Plan for NRC information.

This revision contains the final ASME Section XI examinations and results performed for the WBN Unit 2 PSI program. Additionally, in accordance with Reference 1, TVA previously submitted to the NRC the WBN Unit 2 PSI summary report (Reference

3) that provided an overview of the results from preservice examinations that were performed on components within the ASME Section XI boundary of WBN Unit 2 prior to initial turbine generator synchronization.

There are no regulatory commitments associated with this submittal.

Please address any questions regarding this request to Edward D. Schrull at 423-751-3850.

Applicable Code Edition and Addenda The ASME Boiler and Pressure Vessel B&PV Code,Section XI, 2001 Edition through 2003 Addenda was the code of record, as conditioned by 10 CFR 50.55a, for the PSI period for WBN Unit 2. In accordance with Reference 1, the PSI period for WBN Unit 2 ended with initial turbine-generator synchronization following initial criticality on June 3, 2016. Ill. Applicable Code Requirements ASME Section XI, Subarticle IWB-2200, "Preservice Examination," requires that "preservice examination be extended to include essentially 100% of the pressure retaining welds in all Class 1 components." ASME Section XI, Subarticle IWB-2500, "Examination and Pressure Test Requirements," states that components shall be examined and tested as specified in Table IWB-2500-1, which also requires either a volumetric examination of essentially 100 percent(%)

of the weld volume or a surface examination of essentially 100% of the weld area. The specific item numbers from Table IWB-2500-1 are shown in Table 1. ASME Code Class 2, Table IWC-2500-1, requires either a volumetric examination of essentially 100% of the weld volume or a surface examination of essentially 100% of the weld area. The specific item numbers from Table IWC-2500-1 are shown in Table 1. TVA has invoked ASME Section XI Code Case N-460, which states: "when the entire examination volume or area cannot be examined due to interference by another component or part geometry, a reduction in examination coverage on any Class 1 or Class 2 weld may be accepted provided the reduction in coverage for that weld is less than 10%." Therefore, TV A is requesting relief only for those welds that were inspected and received Code coverage of 90% or less. CNL-16-135 E1-1 of 29 IV. Reason for Request 10 CFR 50.55a(g)(5)(iii), "ISi program update: Notification of impractical ISi Code requirements," states: "If the licensee has determined that conformance with a Code requirement is impractical for its facility the licensee must notify the NRC and submit, as specified in § 50.4, information to support the determinations.

Determinations of impracticality in accordance with this section must be based on the demonstrated limitations experienced when attempting to comply with the Code requirements during the inservice inspection interval for which the request is being submitted.

Requests for relief made in accordance with this section must be submitted to the NRC no later than 12 months after the expiration of the initial or subsequent 120-month inspection interval for which relief is sought." 10 CFR 50.55a(g)(6) authorizes the Nuclear Regulatory Commission (NRC) to grant relief for determinations under 10 CFR 50.55a(g)(5) that code requirements are impractical.

In accordance with 10 CFR 50.55a(g)(6) and 10 CFR 50.55a(g)(5)(iii), TVA is requesting relief from the "essentially 100%" Code-coverage-required weld examination volume or area. As noted in Section Ill of this enclosure, Code Case N-460 states that a reduction in examination coverage on any Class 1 or Class 2 weld may be accepted provided the reduction in coverage for that weld is less than 10%, when the entire examination volume or area cannot be examined due to interference by another component or part geometry.

Therefore, TVA is requesting relief only for those welds that were inspected and received Code coverage of 90% or less. This relief request addresses ASME Section XI Code Class 1 and 2 welds with limited examination coverage in examination categories and item numbers as listed in Table 1. The examination limitations described in this relief request are inherent in the component design, geometry, and materials of construction utilized in the manufacture of the installed components given the original construction permit date for WBN Unit 2 of January 23, 1973. NRC Information Notice 98-42, "Implementation of 10 CFR 50.55a(g) lnservice Inspection Requirements," states, "'Esse.ntially 100 percent' examination is defined as more than 90 percent of the specified examination volume." Additionally, 10 CFR 50.55a(a)(3)(ii) endorses Regulatory Guide 1.147, Rev 17, which unconditionally approves the use of ASME Code Case N-460, "Alternative Examination Coverage for Class 1 and Class 2 Welds,Section XI, Division 1." Code Case N-460 states: "It is the opinion of the Committee that when the entire examination volume or area cannot be examined due to interference by another component or part geometry, a reduction in examination coverage on any Class 1 or Class 2 weld may be accepted provided the reduction in coverage for that weld is less than 10%." The above quote from Code Case N-460 is consistent with the guidance in Information Notice 98-42. This relief request supersedes the one submitted by TVA for WBN Unit 2 in Reference

2. CNL-16-135 E1-2 of 29 V. Impracticality of Compliance Relief is requested on the basis that the Code-required "essentially 100%'; examination coverage is impractical due to physical obstructions and limitations imposed by design, geometry, and/or physical obstructions for the welds and associated components listed in Table 1. For ASME Code Class 1 components, ASME Section XI, IWB-2200, "Preservice Examination" requires that "preservice examination be extended to include essentially 100% of the pressure retaining welds in all Class 1 components." Therefore, no alternate Class 1 welds are available for selection.

Compliance with the examination requirements of ASME Section XI would require significant modification of plant components to remove obstructions, redesign of plant systems/components, or replacement of components where geometry is inherent to the component design. For ASME Code Class 2 components, ASME Section XI, IWC-2200, "Preservice Examination," requires in part, that all examinations required for those components initially selected for examination for ISi, and not exempt, shall be completed prior to initial pla11t startup as a PSI. Compliance with the examination requirements of ASME Section XI would require significant modification of plant components to remove obstructions, redesign of plant systems/components, or replacement of components where geometry is inherent to the component design. VI. Proposed Alternative and Basis for Use TVA performed the ASME Section XI Code-required Preservice volumetric and surface examinations for WBN Unit 2 listed in Table 1, to the maximum extent possible, given the materials and configurations, utilizing qualified/certified personnel, approved procedures, and multiple inspection techniques.

The various types of ultrasonic beams, beam angles, and transducer shapes and sizes utilized for each examination are listed in Table 1 in the column titled Additional Information.

The welds listed in Table 1 were examined, to the maximum extent possible, utilizing qualified/certified personnel, qualified equipment, and approved procedures to meet the PSI acceptance standards of ASME Section XI 2001 Edition through the 2003 Addenda. Surface conditioning of the piping welds was performed to the extent necessary to preclude a reduction in coverage associated with weld crowns, weld shrinkage, and/or surface roughness.

These welds have not been in service and were acceptable to the construction code standards for installation.

The examinations performed on these welds for both construction code and the limited coverage preservice examination are sufficient to ensure structural adequacy of the subject welds. These welds also met the ASME Section Ill NOE acceptance criteria associated with construction.

The construction code radiography, while providing additional assurance of the structural integrity of the subject welds, is not qualified in accordance with ASME Section XI, Appendix VIII, and cannot be credited for ASME Section XI coverage.

The welds listed in Table 1 were subjected to an ASME Code Section Ill hydrostatic pressure test prior to initial plant startup. CNL-16-135 E1-3 of 29 The PSI examination, along with the construction NOE, provides reasonable assurance that unallowable inservice flaws do not exist in the subject welds or that they have been detected and repaired prior to placement into service. Thus, an acceptable level of quality and safety has been achieved and public health and safety has not been endangered by allowing the proposed alternative examination in lieu of the Code requirement.

Attachment 1 to Enclosure 1 provides a compact disc (CD) containing the drawings that support the relief request. VII. Duration of Proposed Alternative This relief request applies to the PSI period for Watts Bar Unit 2 that ended on June 3, 2016, at initial turbine-generator synchronization after initial criticality.
