Farley Nuclear Plant Units 1&2 Vogtle Electric Generating Plant Units 1&2 Proposed Alternative to Use ASME Code Case N-831-1, Ultrasonic Examination in Lieu of Radiography for Welds in Ferritic or Austenitic Pipe Section XI. Division 1 Ladies and Gentlemen:
Pursuant to 10 CFR 50.55a(z)(1), Southern Nuclear Operating Company (SNC) hereby requests Nuclear Regulatory Commission (NRC) approval of proposed Alternative GEN-ISI-ALT-2019-01. The ASME Section XI Code requires that certain ferritic and austenitic pipe welds be examined using radiographic examination techniques to satisfy nondestructive examination requirements.
SNC requests approval to use encoded Phased Array Ultrasonic Examination Techniques (PAUT) in accordance with ASME Section XI Code Case N-831-1, Ultrasonic Examination In Lieu of Radiography for Welds in Ferritic or Austenitic Pipe, as an alternative to radiographic examination. SNC considers the proposed alternative would provide an acceptable level of quality and safety. Enclosure 1 to this letter provides the basis for the proposed alternative.
NRC review and approval of the proposed alternative is respectfully requested by September 30, 2020. This timeline will support anticipated piping repair and replacement activities for the next upcoming refueling outages, currently scheduled to occur during fall 2020.
This letter contains no NRC commitments. If you have any questions, please contact Jamie Coleman at 205.992.6611.

Acceptable Level in Quality and Safety
- 1. ASME Code Component(s) Affected American Society of Mechanical Engineers (ASME) Boiler & Pressure Vessel (B&PV) code,Section XI ferritic and austenitic piping welds requiring radiography during repair/replacement activities.
- 2. Requested Date for Approval Approval is requested by September 30, 2020.
3. Applicable Code Edition and Addenda
The following table identifies the ASME Section XI Code of Record for performing lnservice Inspection (lSI) activities at each applicable Southern Nuclear (SNC) site.
Interval lSI ASME Section XI Interval Plant Interval Edition/Addenda Scheduled Start End Farley Nuclear Plant, 2007 Edition/2008 5 12/01/2017 11/30/2027 Units 1 and 2 Addenda Hatch Nuclear Plant, 2007 Edition/2008 5 01/01/2016 12/31/2025 Units 1 and 2 Addenda Vogtle Nuclear Plant, 2007 Edition/2008 4 05/31/2017 05/30/2027 Units 1 and 2 Addenda
- 4. Applicable ASME Code Requirements The 2007 Edition through the 2008 Addenda of ASME Section XI, paragraph IWA-4221 requires that items used for repair/replacement activities meet the applicable Owner's Requirements and Construction Code requirements when performing repair/replacement activities. IWA-4520 requires that welded joints made for fabrication or installation of items be examined in accordance with the Construction Code identified in the Repair/
Replacement Plan.
5. Reason for Request
Replacement of piping is periodically performed in support of the Flow Accelerated Corrosion (FAC) Program as well as other repair/replacement activities. The use of encoded Phased Array Ultrasonic Examination Techniques (PAUT) in lieu of radiography (RT) to perform the required examinations of fabrication, installation, or repair welds would eliminate the safety risk associated with performing RT, which includes both planned and unplanned radiation exposure to plant workers. PAUT also minimizes the impact on other outage activities normally involved with performing RT such as limited access to work locations. In addition, encoded PAUT is equivalent or superior to the code-required RT E-1
Enclosure to NL-19-0674 Proposed Alternative GEN-ISI-ALT-2019-01 examination for ASME ferritic and austenitic piping repair/replacement welds for detecting and sizing critical (planar) flaws such as cracks and lack of fusion. PAUT provides sizing capabilities for both depth and length dimensions of the flaw, which are required to apply the acceptance criteria of the applicable code case. RT does not provide depth sizing capabilities. This proposed alternative is requested to support both planned and unplanned piping repair and replacement activities.
- 6. Proposed Alternative The use of encoded PAUT is proposed in lieu of the code-required RT examination for ASME ferritic and austenitic piping repair/replacement welds. Similar techniques are being used throughout the nuclear industry for examination of dissimilar metal welds, overlaid welds, as well as other applications including 831.1 piping replacements. This proposed alternative request includes requirements that provide an acceptable level of quality and safety that satisfies the requirements of 10 CFR 50.55a(z)( 1). The capability of the alternative technique is comparable to the examination methods documented in the ASME Code Sections Ill, VIII, and IX, and associated code cases (References 9.1, 9.3, 9.4, 9.5, 9.7, 9.8, 9.9, 9.10, 9.11, 9.12, and 9.13) using ultrasonic examination techniques for weld acceptance. The examinations will be performed using procedures, equipment, and qualified personnel as defined in ASME Code Case N-831-1. The RMS Grading equation, as shown in the 2007 Edition through the 2008 Addenda of ASME Section XI, Article Vlll-3120(d), will be utilized in lieu of the incorrect equation in Section 7(d) of N-831-1.

where m; = measured flaw size f; = true flaw size n = number of flaws measured 6.1 Basis for Use The basis for this proposed alternative is that PAUT is equivalent or superior toRT for detecting and sizing critical (planar) flaws. In this regard, the basis for the proposed alternative was developed from numerous codes, code cases, associated industry experience, articles, and the results of RT and encoded PAUT examinations. The examination procedure and personnel performing examinations are qualified using representative piping conditions and flaws that demonstrate the ability to detect and size flaws that are both acceptable and unacceptable to the defined acceptance standards.
The demonstrated ability of the examination procedure and personnel to appropriately detect and size flaws provides an acceptable level of quality and safety alternative as allowed by 10 CFR 50.55a(z)(1 ).
It should also be noted that Code Case N-831 (Revision 0), which provides rules for performing ultrasonic examination of welds in ferritic piping in lieu of RT, is listed in Table 2, "Conditionally Accepted Section XI Code Cases," of Draft Regulatory Guide DG-1342. As stated in the Proposed Rule published in Vol. 83, No. 159 of the Federal Register, dated E-2
Enclosure to NL-19-0674 Proposed Alternative GEN-ISI-ALT-2019-01 Thursday, August 16, 2018, The NRC finds the Code Case acceptable with the condition that it is prohibited for use in new reactor construction."
