SUBJECT:

RIVER BEND STATION ALERT AND NOTIFICATION SYSTEM EVALUATION REPORT

Dear Ms. Hoffman:

On behalf of the U.S. Nuclear Regulatory Commission (NRC), I am responding to your letter dated February 6, 2025, which provided the Federal Emergency Management Agency (FEMA) approval of Revision D of the River Bend Station (RBS) Alert and Notification System Evaluation Report (ANS Design Report) which was received on February 7, 20251.

As described in Revision D of the RBS ANS Design Report, the station switched its primary alert method, from sirens to the Integrated Public Alert and Warning System - Wireless Emergency Alert (IPAWS-WEA) as the primary alerting and notification methods for the 10-mile Emergency Planning Zone. That is, the primary notification method will remain as Emergency Alert System (EAS) but activated through IPAWS. The report also describes RBS maintaining route alerting and notification as the backup ANS system.

Per Section V, Parts A and B of the Memorandum of Understanding (MOU) between the Department of Homeland Security (DHS/FEMA) and the NRC regarding radiological emergencies, planning, and preparedness, dated July 1, 20242:

FEMA coordinates all Federal planning for offsite impact of radiological emergencies and takes the lead for assessing offsite radiological emergency response plans and preparedness, makes findings and determinations as to the adequacy and capability of implementing offsite plans, and communicates those findings and determinations to the NRC. As outlined within Section V, Part A, FEMA Approves Alert and Notification System (ANS) design reports. When the ANS design report undergoes significant changes, including any changes to primary and back-up alert methods, FEMA will allow the NRC to review the ANS design report to ensure that the NRC-regulated aspects of ANS are maintained.

As outlined within Section V, Part B:

The NRC reviews FEMA's findings and determinations in conjunction with the NRC onsite findings for the purpose of making determinations on the overall state of emergency preparedness. These overall findings and determinations are used by the 1 NRCs Agencywide Documents Access and Management System (ADAMS) Accession No. (ML25041A200) 2 ADAMS (ML24184A043)

March 3, 2025

NRC to make radiological health and safety decisions in the issuance of licenses and the continued operation of licensed utilization facility to include taking enforcement actions such as notices of violations, civil penalties, orders, or shutdown of operating reactors.

This delineation of responsibilities avoids duplicative efforts by the NRC in preparedness matters.

Additionally, as outlined within Part B, the NRC:

Reviews FEMA's findings and determinations of offsite plans to determine that the plans, including ANS design reports, are adequate and can be effectively implemented.

The NRC evaluated the updated River Bend ANS Design Report received on February 7, 2025, and found that it contained sufficient information to be considered an adequate submittal for NRC to conduct its review. At this time, the NRC did not identify any licensing basis issues associated with the River Bend ANS Design Report.

Consistent with the roles of each respective agency as set forth in the aforementioned MOU, the NRC conducted a review of the FEMA findings. To aid its review, the NRC utilized the FEMA evaluation criteria and sample template for ANS changes and use of IPAWS3. The NRC review focused on the applicable requirements in Title 10 of the Code of Federal Regulations (10 CFR)

Section 50, Appendix E,Section IV.D.3.

The NRC staff conducted a risk-informed assessment and thorough review to determine if there is reasonable assurance that backup capability for alert and notification would be available in the event the primary ANS is unavailable during an emergency. The staff concluded that the back-up capability does exist.

In conclusion, the NRC accepts the findings of FEMA that Revision D of the River Bend Station Alert and Notification System Evaluation Report meets the applicable requirements in 10 CFR 50, Appendix E,Section IV.D.3, and enables the NRC to make a finding of reasonable assurance for public health and safety.

Please feel free to contact my staff, Cindy Rosales-Cooper, Acting Chief, Policy and Oversight Branch at (301) 287-9500 or at Cindy.Rosales-Cooper@nrc.gov, if you have questions.
