Subject:

Supplement to Application to Revise Technical Specifications to Adopt TSTF-566 , "Revise Actions for Inoperable RHR Shutdown Cooling Systems"

Reference:

Letter from P.R. Simpson (Exelon) to U.S. NRC, "Application to Revise Technical Specifications to Adopt TSTF-566, 'Revise Actions for Inoperable RHR Shutdown Cooling Systems'," dated April 13, 2020 (ML20104C104)

In accordance with 10 CFR 50.90, "Application for amendment of license, construction permit, or early site permit," Exelon Generation Company, LLC (EGC), proposed a change to the Technical Specifications (TS),

Appendix A of Facility Operating License (FOL) No. NPF-62 for Clinton Power Station , Unit 1, Renewed FOL Nos. DPR-19 and DPR-25 for Dresden Nuclear Power Station, Units 2 and 3, Renewed FOL No. DPR-59 for James A. FitzPatrick Nuclear Power Plant, Renewed FOL Nos. NPF-11 and NPF-18 for LaSalle County Station, Units 1 and 2, Renewed FOL No. NPF-69 for Nine Mile Point Nuclear Station, Unit 2, Renewed FOL Nos. DPR-44 and DPR-56 for Peach Bottom Atomic Power Station, Units 2 and 3, and Renewed FOL Nos. DPR-29 and DPR-30 for Quad Cities Nuclear Power Station, Units 1 and 2. The proposed changes are consistent with previously NRC-approved Industry/Technical Specifications Task Force Traveler 566 (TSTF-566), Revision 0, "Revise Actions for Inoperable RHR Shutdown Cooling Systems."

During preparation and review of clean TS pages to be submitted to the NRC, it was identified that the addition of the word "required" for the proposed new Required Action B.1 would result in improved consistency of wording within the TS for Dresden Nuclear Power Station and Peach Bottom Atomic Power Station. The updated marked-up TS pages for these two plants are included in Attachments 1 and 2, respectively. These pages supersede those included in the Reference for these two plants in their entirety.

EGC has reviewed the information supporting a finding of no significant hazards consideration , and the environmental consideration, that were previously provided to the NRC in Reference 1. EGC has concluded

January 29, 2021 U.S . Nuclear Regulatory Commission Page 2 that the information provided in this response does not affect the bases for concluding that the proposed license amendment does not involve a significant hazards consideration under the standards set forth in 10 CFR 50.92. In addition, EGC has concluded that the information in this supplemental letter does not affect the bases for concluding that neither an environmental impact statement nor an environmental assessment needs to be prepared in connection with the proposed amendment.

In accordance with 10 CFR 50.91, "Notice for public comment; State consultation," paragraph (b), EGC is notifying the State of Illinois and the State of Pennsylvania of this supplement to the proposed TS pages by transmitting a copy of this letter and its attachments to the designated State Officials.

There are no regulatory commitments contained in this letter. Should you have any questions concerning this letter, please contact Ms. Rebecca L. Steinman at (630) 657-2831 .

I declare under penalty of perjury that the foregoing is true and correct. Executed on the 291h day of January 2021 .
