Remove Nine Mile Point 3 Nuclear Project Designation July 31, 2024 Page 2 (NMP3) designation from the Technical Specifications (TS). By letter dated February 1, 2024, CEG provided a supplemental letter with information to further clarify the changes to the figures (Reference 2). More specifically, Section 5.0, "Design Features," in Renewed Facility Operating License DPR-63 for Nine Mile Point Nuclear Station, Unit 1 (NMP1) and Section 4.0, Design Features," Figure 4.1-1, in Renewed Facility Operating License NPF-69 for Nine Mile Point Nuclear Station, Unit 2 (NMP2) will be revised to reflect the proposed TS changes.

Upon further review, CEG determined that the proposed changes are not clearly representing the TS figures prior to the approval of Reference 3. This Supplemental Information Letter provides corrected NMP1 and NMP2 figure markups and clean, "camera-ready," TS pages by utilizing the approved TS figures provided in Reference 3 as the base figures for the TS markups and ensuring that the proposed changes are consistently and accurately applied.

Through these proposed changes, the TS figures will more closely reflect the plant area boundaries prior to approval of Reference 3 with some additional minor administrative differences. These additional minor differences include the addition of NMP "Unit 2" designation and the removal of the railroad tracks on both NMP1 and NMP2 figures. These minor differences provide added clarity to the figures and are administrative in nature.

In addition, the extension to the requested approval date from February 16, 2024, to August 18, 2024, as requested in Reference 2, is superseded by this supplemental letter. The revised requested approval date is September 30, 2024.

The supplemental information in this letter includes a description of changes in Attachment 1, revised NMP1 TS Markups and camera-ready pages in Attachment 2, and the revised NMP2 TS markup and camera-ready page in Attachment 3. The information in Attachments 2 and 3 supersede in their entirety the previous TS markups and camera-ready pages provided in Reference 1 and Reference 2.

There are no regulatory commitments contained within this letter.

In accordance with 10 CFR 50.91, "Notice for public comment; State consultation," paragraph (b), CEG is notifying the State of New York of this application for license amendment by transmitting a copy of this letter and its attachments to a designated State Officials.

Should you have any questions concerning this letter, please contact Ron Reynolds at (267) 533-5698.

I declare under penalty of perjury that the foregoing is true and correct. This statement was executed on the 31st day of July 2024.

Respectfully, David T. Gudger Senior Manager - Licensing Constellation Energy Generation, LLC

ATTACHMENT 1 Nine Mile Point Nuclear Station, Docket Nos. 50-220 and 50-410 Supplemental Information-Description of Changes

Description of Changes Docket Nos. 50-220 and 50-410 Page 1 of 1 By letter dated August 18, 2022, Constellation Energy Generation, LLC (CEG) submitted proposed changes to Technical Specifications (TS) figures for Nine Mile Point Unit 1 (NMP1) and Nine Mile Point Unit 2 (NMP2).

The proposed changes were to revise the TS figures to reflect as they were prior to Amendments 212 and 142 approved on July 12, 2012 (ML12157A556), for NMP1 and NMP2, respectively. In a supplemental letter dated February 1, 2024, further clarifications to the figure revisions were provided.

This Supplemental Information Letter provides corrected NMP1 and NMP2 figure markups and clean, "camera-ready," TS pages by utilizing the approved TS figures provided in Amendment 212 and 142 as the base figures for the TS markups and ensuring that the proposed changes are consistently and accurately applied. Through these proposed changes, the TS figures will more closely reflect the plant area boundaries prior to approval of Amendment 212 and 142 with some additional minor administrative differences. The changes in Attachments 2 and 3 include:

x Revised NMP1 TS Section 5.1 with Insert 1 on page 342.

x Added the legend with Insert 2 on NMP1 TS page 344 and added associated legend indicators to NMP1 Figure 5.1-1 on TS page 343.

x Changed "Entergy Nuclear Fitzpatrick, LLC" to "Constellation Fitzpatrick, LLC," on both figures to reflect consistency with Fitzpatrick's operating license.

x Added the "Unit 2" designation to both figures.

x Removed the railroad tracks from both figures for clarity.

x Deleted the Nine Mile Point Nuclear Project, LLC, designation and the associated boundary line from both figures.

x Deleted the second bullet at the bottom of each figure.

The above changes supersede in their entirety the changes to figures previously submitted in CEGs submittals dated August 18, 2023, and February 1, 2024.

This supplemental information letter also requests an extension to the NRC approval date for this licensing action from August 18, 2024, as requested in CEG letter dated February 1, 2024, to September 30, 2024.

Insert 1 Insert 1 The Nine Mile Point Nuclear Station and James A. Fitzpatrick Nuclear Power Plant site comprising approximately 1500 acres, is located on the shores of Lake Ontario, about seven miles northeast of Oswego, New York. An exclusion distance of nearly 4000 feet is provided between the Station and the nearest site boundary to the west, a mile to the boundary on the east, and a mile and a half to the southern site boundary (as described in the Sixth Supplement of the UFSAR).

Figure 5.1-1 is a Site Boundary Map of Nine Mile Point which allows the identification of gaseous and liquid waste release points. Figure 5.1-1 also defines the unrestricted area within the site boundary that is accessible (except for fenced areas) to members of the public.
