In Reference 1, Tennessee Valley Authority (TVA) submitted a license amendment request (LAR) for the Watts Bar Nuclear Plant (WBN) Units 1 and 2 to modify the WBN Technical Specifications (TS), by relocating specific surveillance frequencies to a licensee-controlled program with the implementation of Nuclear Energy Institute (NEI) 04-10, Risk-Informed Technical Specifications Initiative 5b, Risk-Informed Method for Control of Surveillance Frequencies, in accordance with Technical Specification Task Force (TSTF) Standard Technical Specifications Change TSTF-425, Revision 3. In Reference 2, TVA submitted a response to a request for additional information (RAI) regarding this LAR. In Reference 3, TVA submitted a correction letter for an element of the LAR. In Reference 4, TVA submitted a supplement to the LAR to rescind one of the proposed Surveillance Requirements (SR)

Frequency changes and to make several errata changes to the LAR.

U.S. Nuclear Regulatory Commission CNL-19-084 Page 3 January 17, 2020 The purpose of this letter is to provide an additional supplement to the Reference 1 LAR to address several overlapping licensing actions, as described below.

x In Reference 5, the Nuclear Regulatory Commission (NRC) issued License Amendments 122/21 for WBN Units 1 and 2, respectively, which revised Surveillance Requirements (SRs) 3.2.4.1 and 3.2.4.2 with frequencies that are also proposed to be controlled under the Surveillance Frequency Control Program (SFCP) by Reference 1. These amendments were inadvertently not included in the Reference 1 LAR.

x In Reference 6, the NRC issued License Amendments 126/29 for WBN Units 1 and 2, respectively, after the Reference 1 LAR had been submitted. These amendments revised TS Pages 3.8-42/3.8-38 that the Reference 1 LAR markup and clean pages had been based. In Reference 7, the NRC issued License Amendments 129/32 for WBN Units 1 and 2, respectively, which further revised these pages, and also revised SRs 3.8.7.1 and SRs 3.8.8.1 with frequencies that are also proposed to be controlled under the SFCP by Reference 1.

x In Reference 8, the NRC issued License Amendments 128/31 for WBN Units 1 and 2, respectively, after the Reference 1 LAR had been submitted. These amendments revised certain TS pages that the Reference 1 LAR markup and clean pages had been based.

Accordingly, in Enclosure 1 TVA is providing change instructions to update the Reference 1 LAR based on the pages issued with the Reference 5, 6, 7, and 8 License Amendments.

Additional changes unrelated to the SFCP are included to correct administrative formatting in accordance with the TSTF-GG-05-01, Revision 1, Writers Guide for Plant-Specific Improved Technical Specifications, and the formatting conventions of NUREG-1431, Revision 4.0, Standard Technical Specifications Westinghouse Plants.

In Reference 9, the NRC issued License Amendments 125/27 for WBN Units 1 and 2, respectively, which revised an existing surveillance (SR 3.9.9.1) whose Frequency was proposed to be controlled under the SFCP in the Reference 1 LAR. These amendments also added a new SR 3.7.18.1 which is candidate for inclusion in the SFCP. However, as noted in Reference 9, Amendments 125/27 are not scheduled for implementation until prior to startup from the outage where any number of tritium producing burnable absorber rods is inserted in the Watts Bar Nuclear Plant, Unit 2 reactor core, not to exceed December 31, 2022. The tritium producing burnable absorber rods are currently scheduled to be inserted for WBN Unit 2 prior to the start of WBN Unit 2 Cycle 4 (projected in Fall 2020), which will exceed the requested 60-day implementation period for the Reference 1 LAR. In order to avoid having to submit a supplemental LAR to capture these SRs within the SFCP, TVA proposes a bifurcated implementation schedule for the Reference 1 LAR.

The SR 3.7.18.1 and 3.9.9.1 Frequencies will be established under the SFCP consistent with the above License Amendments 125/27 implementation schedule, with the balance of the Reference 1 LAR proposed changes implemented within 60-days of approval. Finally, Amendments 125/27 established the Spent Fuel Storage Rack Monitoring Program under TS Section 5.7.2.21, which was also the proposed section number for the discussion of the

Enclosure 1 Change Instructions to the October 12, 2018, License Amendment Request Associated with License Amendments 122/21, 126/29, 128/31, and 129/32, and Other Miscellaneous Changes (4 Pages)

Discussion This Enclosure contains six addenda that are driving modifications to the October 12, 2018 License Amendment Request (LAR). Within each addendum, the modification pages are provided in the order that they appear in the LAR.

Addendum 1 License Amendments 122/21 (ML18197A307) were issued on August 30, 2018. These amendments have intersections with the TSTF-425 LAR in TS 3.2.4 as specified below.

- Surveillance Requirements (SRs) 3.2.4.1 and 3.2.4.2 were revised slightly. The revised SRs remain closely aligned with TSTF-425 SR 3.2.4.1 and 3.2.4.2, and the Frequency remains eligible to licensee control in accordance with the Surveillance Frequency Control Program (SFCP), consistent with the TSTF-425 Model Safety Evaluation (SE). These changes remain as administrative variations as described in Attachment 1, Section 2.2.1.1 of the TSTF-425 License Amendment Request (LAR).

Changes to Attachments 3.1, 3.2, 4.1, and 4.2 of the TSTF-425 LAR are provided that are reflective of these changes.

Addendum 2 License Amendments 126/29 (ML19098A774) were issued on June 7, 2019, which revised TS Pages 3.8-42/3.8-38 that had also been designated for change in the TSTF-425 LAR.

License Amendments 129/32 (ML19238A005) were issued on November 26, 2019, which also affected these pages. Additionally, Amendments 129/32 have intersections with the TSTF-425 LAR in SR 3.8.7.1 and SR 3.8.8.1. As a result:

- Surveillance Requirements (SRs) 3.8.7.1 and 3.8.8.1 were revised. The new wording closely aligns with TSTF-425 SR 3.8.7.1 and 3.8.8.1, and the Frequencies remains eligible for licensee control in accordance with the Surveillance Frequency Control Program (SFCP),

consistent with the TSTF-425 Model Safety Evaluation (SE). These changes remain as administrative variations as described in Attachment 1, Section 2.2.1.1 of the TSTF-425 LAR.

- TS 3.8.9 Conditions E and F were re-designated as Conditions G and H, and relocated from Page 3.8-42 to 3.8-42a for WBN1, which is also the page containing the change to SR 3.8.9.1 for control under the SFCP. The WBN2 change was similarly shifted from Page 3.8-38 to 3.8-38a.

Changes to Attachments 3.1, 3.2, 4.1, and 4.2 of the TSTF-425 LAR are provided that are reflective of these changes. Changes to Attachment 7, Page 35 of 37, for the SR 3.8.7.1 and SR 3.8.8.1 entries are shown in Enclosure 3, which has other changes on that same page.

CNL-19-084 E1-1 of 2

Enclosure 1 Addendum 3 License Amendments 128/31 (ML18277A110) were issued on August 27, 2019. These amendments have intersections with several TS pages upon which the TSTF-425 LAR markup and clean pages were based. Corrections are also made to the alignment of WBN1 Page 3.3-50 for Required Action C.1 and its Completion Time, and the lower border line, as well as insertion of additional line spaces before the start of the Surveillance Requirements. These are administrative changes consistent with TSTF-GG-05-01, Revision 1, Writers Guide for Plant Specific Improved Technical Specifications and NUREG-1431. Revised pages are provided for Attachments 3.1, 3.2, 4.1, and 4.2.

Addendum 4 License Amendment 68 (ML081620043) inserted the Notes for SR 3.3.6.2 and SR 3.3.6.3 on WBN1 Page 3.3-55. These Notes were reformatted in License Amendment 92 (ML13141A564) and was re-established as Page 3.3.54. In neither amendment were these Notes properly formatted in conformance with TSTF-GG-05-01. Page 3.3-54 is therefore revised to properly format these Notes consistent with TSTF-GG-05-01 and WBN2 Page 3.3-56, and contains no technical change in content.

Addendum 5 License Amendment 5 (ML020790130) revised the Frequency of WBN1 SR 3.6.2.1 on Page 3.6-7 to be In accordance with the Containment Leakage Rate Testing Program.

However, the placement of this Frequency was misaligned per the guidance of TSTF-GG-05-01.

Page 3.6-7 is revised to properly align this Frequency consistent with WBN2 Page 3.6-6, and contains no technical change in content.

Addendum 6 With the issuance of the WBN2 Operating License, the Frequencies for SR 3.6.11.5 and SR 3.6.11.7 on Page 3.6-27 were misaligned per the guidance of the TSTF-GG-05-01.

Page 3.6-27 is revised to properly align these Frequencies consistent with WBN1 Page 3.6-30, and contain no technical changes in content.

Note: General page instructions are provided in green font. Specific changes on each page are provided in red font.

Enclosure 2 Change Instructions to the October 12, 2018, License Amendment Request Associated with License Amendments 125/27 (23 Pages)

Discussion License Amendments 125/27 (ML18347B330) were issued on May 22, 2019. These amendments have an intersection with the TSTF-425 License Amendment Request (LAR) in TS 3.7.18 and TS 3.9.9, as well as in TS Section 5.7.2.21. Specifically:

- Surveillance Requirement (SR) 3.7.18.1 is a new surveillance. The SR closely aligns with TSTF-425 SR 3.7.16.1, and the Frequency is eligible for licensee control in accordance with the Surveillance Frequency Control Program (SFCP), consistent with the TSTF-425 Model Safety Evaluation (SE). Its addition qualifies as an administrative variation as described in Attachment 1, Section 2.2.1.1 of the TSTF-425 LAR. Page 3.7-40 is added to Attachments 3.1 and 4.1, and Page 3.7-38 is added to Attachments 3.2 and 4.2. Bases Page B 3.7-93 is added to Attachment 5. Page 26 of 37 of Attachment 7 is revised.

- SR 3.9.9.1 was revised to change the fuel storage pool boron concentration from 2000 ppm to 2300 ppm and additionally removed a Frequency requirement Prior to movement of fuel in the spent fuel pool. Although there is no analogous TSTF-425 SR, it remains eligible for licensee control in accordance with the SFCP, consistent with the TSTF-425 Model SE. The revised SR remains an administrative variation as described in Attachment 1, Section 2.2.1.5 of the TSTF-425 LAR. Page 3.9-16 is replaced in Attachment 3.1 and 4.1, and Page 3.9-12 is replaced in Attachment 3.2 and 4.2. Page 37 of 37 of Attachment 7 is revised.

- The Spent Fuel Storage Rack Monitoring Program is now described in TS Section 5.7.2.21, which was also the proposed location for the description of the SFCP. TS Section 5.7.2.22 has been assigned to the Battery Monitoring and Maintenance Program, as described in Enclosure 3. Accordingly, the SFCP location has been re-assigned to TS Section 5.7.2.23.

Specifically, Insert 2 from Attachments 3.1 and 3.2 are replaced. Pages 5.0-25a is deleted and Page 5.0-25b is added to Attachment 3.1. Page 5.0-27 is deleted and Page 5.0-27b is added to Attachment 3.2. Page 5.0-25a is deleted and Page 5.0-25c is added to Attachment 4.1. Pages 5.0-27 and 5.0-27a are deleted and Page 5.0-27a is added in Attachment 4.2. Page 37 of 37 from Attachment 7 is replaced.

The above changes to Attachments 3.1, 3.2, 4.1, 4.2, 5, and 7 of the TSTF-425 LAR are provided in the following pages as they are ordered in the LAR. Note: General page instructions are provided in green font. Specific changes on each page are provided in red font.

Enclosure 3 Change Instructions to the October 12, 2018, License Amendment Request Associated with License Amendments 130/33 (4 Pages)

Discussion License Amendments 130/33 (ML19276E557) were issued on December 9, 2019. These amendments have intersections with the TSTF-425 LAR in TS 3.8.4, and 3.8.6. These amendments require updates be made to the TSTF-425 License Amendment Request.

Specifically, the proposed updates are as follows:

- Surveillance Requirements (SRs) 3.8.4.1 and 3.8.4.2 are revised. The new wording closely aligns with TSTF-425 SR 3.8.4.1, and the Frequency remains eligible for licensee control in accordance with the Surveillance Frequency Control Program (SFCP), consistent with the TSTF-425 Model Safety Evaluation (SE).

- SRs 3.8.4.5, 3.8.4.6, 3.8.4.7, 3.8.4.8, 3.8.4.9, 3.8.4.10, 3.8.4.11, and 3.8.4.12 are deleted.

Therefore, the previously proposed Frequency changes to the SFCP are no longer applicable.

- SR 3.8.4.14 is relocated to SR 3.8.6.7, and SR 3.8.4.13 Note 1 is revised reflect that change (and is re-designated as SR 3.8.4.7 to reflect the prior SR deletions, as noted below). The previously proposed SR 3.8.4.14 Frequency change to the SFCP remains applicable.

- New SR 3.8.4.5 is proposed. The SR closely aligns with TSTF-425 SR 3.8.4.2, and the Frequency is eligible for licensee control in accordance with the SFCP, consistent with the TSTF-425 Model SE.

- New SR 3.8.4.6 is proposed. The SR partially aligns with TSTF-425 SR 3.8.4.2, and the Frequency is eligible for licensee control in accordance with the SFCP, consistent with the TSTF-425 Model SE.

- SR 3.8.4.13 is re-designated as SR 3.8.4.7, and revises Note 1. This as-revised SR closely aligns with TSTF-425 SR 3.8.4.3, and the Frequency is eligible for licensee control in accordance with the SFCP, consistent with the TSTF-425 Model SE.

- SRs 3.8.6.1, 3.8.6.2, and 3.8.6.3 are being deleted. Therefore, the previously proposed Frequency changes to the SFCP are no longer applicable.

- New SRs 3.8.6.1, 3.8.6.2, 3.8.6.3, 3.8.6.4, 3.8.6.5, and 3.8.6.6 are proposed. The SRs closely align with TSTF-425 SR 3.8.6.1, 3.8.6.2, 3.8.6.3, 3.8.6.4, 3.8.6.5, and 3.8.6.6, and the Frequencies are eligible for licensee control in accordance with the SFCP, consistent with the TSTF-425 Model SE.

- TS Section 5.7.2.22 now describes the Battery Monitoring and Maintenance Program, which along with Amendments 125/27 have caused relocation of the Surveillance Frequency Control Program description to TS Section 5.7.2.23. This is described in further detail in Enclosure 2.
