Dear Mr. Moul:

The U.S. Nuclear Regulatory Commission has issued the enclosed additional page for Renewed Facility Operating License (RFOL) No. NPF-86 for the Seabrook Station, Unit No. 1.

This page memorializes the amendment to RFOL No. NPF-86 by the Initial Decision (Ruling on the Reformulated Contention) of the Atomic Safety and Licensing Board, dated August 21, 2020 (LBP-20-09), as modified by the Memorandum and Order (Denying Motion to Reopen, Motion for Leave, and Motion for Partial Reconsideration; Granting in Part and Denying in Part Motion for Leave to Reply), dated November 6, 2020 (LBP-20-12), which was immediately effective pursuant to Title 10 of the Code of Federal Regulations 2.340(f).

Specifically, the additional page includes four additional conditions in RFOL No. NPF-86 for Appendix C that the Board found necessary for Amendment No. 159 to satisfy regulatory requirements.

If you have any questions, please contact me at (301) 415-2048 or at Justin.Poole@nrc.gov.

Sincerely,

/RA/

Justin C. Poole, Project Manager Plant Licensing Branch I Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket No. 50-443

--- Appendix C, page 3 Enclosure

Amendment Additional Condition Implementation Number Date (continued)

(c) NextEra shall undertake the monitoring required by MPR-4273, Revision 1, Appendix B, Check 3, for control extensometers every six months.

(d) If stress analyses conducted pursuant to the Structural Evaluation Methodology show that the stress in the rebar from ASR-induced expansion and other loads will exceed the yield strength of the rebar, NextEra must develop a monitoring program sufficient to ensure that rebar failure or yielding does not occur, or is detected if it has already occurred, in the areas at-risk of rebar failure or yielding.

(e) If the ASR expansion rate in any area of a Seabrook seismic Category I structure significantly exceeds 0.2 mm/m (0.02%) through-thickness expansion per year, NextEras Management will perform an engineering evaluation focused on the continued suitability of the six-month monitoring interval for Tier 3 areas. If the engineering evaluation concludes that more frequent monitoring is necessary, it shall be implemented under the Structures Monitoring Program.

(f) Each core extracted from Seabrook Unit 1 will be subjected to a petrographic analysis to detect internal microcracking and delamination.
