SUBJECT:

SHEARON HARRIS NUCLEAR POWER PLANT, UNIT 1 - CORRECTION TO AMENDMENT NO. 184 REGARDING TECHNICAL SPECIFICATIONS TASK FORCE (TSTF) TRAVELER TSTF-505, REVISION 2, PROVIDE RISK INFORMED EXTENDED COMPLETION TIMES - RITSTF INITIATIVE 4B (EPID L-2019-LLA-0218)

Dear Ms. Maza:

On April 2, 2021 (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML21047A314), the U.S. Nuclear Regulatory Commission (NRC) issued Amendment No. 184 to Renewed Facility Operating License No. NPF-63 for the Shearon Harris Nuclear Power Plant, Unit 1. This amendment was in response to your application dated October 7, 2019, as supplemented by letters dated July 27, 2020, and November 11, 2020.

The amendment revised Technical Specification (TS) requirements to permit the use of risk-informed completion times (RICT) for actions to be taken when limiting conditions for operation are not met. The changes are consistent with Technical Specifications Task Force (TSTF) Traveler TSTF-505, Revision 2, Provide Risk-Informed Extended Completion Times - RITSTF Initiative 4b, dated July 2, 2018.

Subsequent to issuance of the amendment, a discrepancy was identified with TS page 3/4 3-26.

Your supplement dated July 27, 2020, indicated that Table 3.3-3 Functional Unit 6.f was initially planned for inclusion within the scope of the RICT Program by updating Action 15 on TS Page 3/4 3-26 to include or in accordance with the Risk-Informed Completion Time Program.

However, as noted in your supplement dated July 27, 2020, with removing Functional Unit 6.f from the scope of the Program, there was no longer a need to update Action 15. Page 9 of the safety evaluation has been updated to reflect the removal of Action 15 from the individual limiting conditions for operation Action statements. The NRC staff has determined that this error was made inadvertently.

The purpose of this letter is to issue a correction to TS page 3/4 3-26 for Amendment No. 184 and revise page 9 of the safety evaluation. The NRC concludes that the correction is entirely editorial in nature and does not change the staffs previous conclusion in the safety evaluation for Amendment No. 184, nor does it affect the no significant hazards consideration, as published in the Federal Register on January 14, 2020 (85 FR 2160). Enclosed, please find the corrected TS page 3/4 3-26 and page 9 of the safety evaluation.

K. Maza If you have any questions regarding this matter, please contact me at (301) 415-1387 or by e-mail at Tanya.Hood@nrc.gov.

Sincerely,

/RA/
