SUBJECT: SCHEDULE REVISION FOR THE SAFETY AND ENVIRONMENTAL REVIEWS

OF THE SEABROOK STATION, UNIT 1 LICENSE RENEWAL APPLICATION 

(TAC NOS. ME4028 AND ME3959)

Dear Mr. Walsh:

By letter dated May 25, 2010, NextEra Energy Seabrook, LLC (NextEra) submitted an 

application for review by the U.S. Nuclear Regulatory Commission (NRC, the staff), pursuant to 

Title 10 of the Code of Federal Regulations (10 CFR) Part 51 and 10 CFR Part 54, to renew

Operating License No. NPF-86 for Seabrook Station, Unit 1 (Seabrook). This letter is to inform 

you of a change in the safety and environmental review schedules for the Seabrook license 

renewal review.

By letter dated September 11, 2014, the staff notified NextEra of the revised safety review 

schedule and established new dates for the proposed second Advisory Committee on Reactor 

Safeguards (ACRS) Subcommittee Meeting regarding alkali-silica reaction (ASR) at Seabrook, 

the issuance of the final Safety Evaluation Report (SER), and the ACRS full committee meeting. 

By this letter, the staff is revising the safety review schedule because the staff needs additional 

information to complete its review of unresolved technical issues associated with ASR. The 

scheduled date for the second ACRS Subcommittee meeting is being revised from June 2015 to 

December 2015; the scheduled date for the issuance of the final SER is being revised from 

November 2015 to May 2016; and the scheduled date for the ACRS full committee meeting is 

being revised from January 2016 to July 2016. The delays in these critical license renewal 

activities have also delayed the scheduled decision regarding the renewed license for Seabrook 

from March 2016 to September 2016. 

The staff notes that to complete all necessary safety review milestones (i.e., issue the final SER 

and conduct the ACRS full committee meeting) to support the September 2016 final decision on 

the renewed license for Seabrook, NextEra needs to resolve all technical issues associated with 

ASR. After receipt of your response regarding the unresolved ASR technical issues, the staff 

will review the response, determine if there is reasonable assurance that the safety concern(s) 

and aging management issue(s) are addressed, and then document the final determination in 

the SER. The completeness and quality of your response is essential to maintain the revised 

schedule, and any delay or incomplete response could result in additional schedule revisions, 

with the potential of leaving milestone schedule dates as “to be determined”.

Regarding the environmental review, the staff is revising the scheduled date for the issuance of 

the final Supplemental Environmental Impact Statement (SEIS) from May 2015 to July 2015. 

Due to resource allocation and priorities, the staff needs additional time to complete the final 

SEIS. 

Enclosed is the NRC staff's revised review schedule for the Seabrook license renewal 

application. If you have any questions related to this revised safety schedule, please contact 

Richard Plasse, at 301-415-1427 or by e-mail at Richard.Plasse@nrc.gov. If you have any 

questions related to the revised environmental schedule, please contact Lois James at 

301-415-3306 or by e-mail at Lois.James@nrc.gov.

Sincerely,

/RA/
