1.0 INTRODUCTION
By application dated May 12, 2025 (Agencywide Documents Access and Management System Accession No. ML25132A013 ), as supplemented by letter dated January 12, 2026 (ML26012A290), NextEra Energy Seabrook, LLC (NextEra), requested U.S. Nuclear Regulatory Commission (NRC, the Commission) review and approval of a proposed license amendment request (LAR) to revise the Seabrook Station, Unit No.1 (Seabrook) Renewed Facility Operating License NPF-86, pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 50.90, Application for amendment of license, construction permit, or early site permit. Specifically, the proposed LAR would revise Emergency Action Levels (EALs) for Initiating Condition (IC) HU4 in procedure ER 1.1, Classification of Emergencies, for Seabrook. A new fire detection system is to be installed inside the Seabrook Containment Building, which is different than the existing system and requires changes to EALs for IC HU4.
The supplemental letter dated January 12, 2026, provided additional information that clarified the application, but did not expand the scope of the application as originally noticed, or changed the NRCs original proposed no significant hazards consideration determination as published in the Federal Register (FR) on July 8, 2025 (90 FR 30113). The current EAL scheme for Seabrook was last approved via license amendment No. 152, issued on February 10, 2017 (ML16358A411), and follows the guidance in Nuclear Energy Institute (NEI) 99-01, Revision 6.
REGULATORY EVALUATION The regulatory requirements and guidance on which the NRC staff based its review are provided below.
EAL Regulations The planning standard of 10 CFR 50.47(b)(4) requires:
A standard emergency classification and action level scheme, the bases of which include facility system and effluent parameters, is in use by the nuclear facility licensee, and State and local response plans call for reliance on information
