UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Mr. Kevin Walsh, Site Vice President c/o Michael Ossing Seabrook Station NextEra Energy Seabrook, LLC P.O. Box 300 Seabrook, NH 03874 March 13, 2014
SUBJECT:
SEABROOK STATION, UNIT 1-REQUEST FOR ADDITIONAL INFORMATION FOR LICENSE AMENDMENT REQUEST 13-03, "APPLICATION FOR TECHNICAL SPECIFICATION CHANGE REGARDING RISK-INFORMED JUSTIFICATIONS FOR RELOCATION OF SPECIFIC FREQUENCY REQUIREMENTS TO A LICENSEE-CONTROLLED PROGRAM" (TAC NO. MF1958)
Dear Mr. Walsh:
By letter dated May 28, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13155A002), as supplemented January 29, 2014 (ADAMS Accession No. ML14035A457), NextEra Energy Seabrook, LLC (NextEra) submitted license amendment request 13-03 for Seabrook Station, Unit 1 (Seabrook). The proposed change is to the Seabrook technical specifications (TSs). Specifically, the proposed amendment would modify the TSs by relocating specific surveillance frequencies to a licensee-controlled program with implementation of Nuclear Energy Institute (NEI) 04-10, "Risk-Informed Technical Specification Initiative 5b, Risk-Informed Method for Control of Surveillance Frequencies." The changes are consistent with U.S. Nuclear Regulatory Commission (NRC)-
approved TS Task Force (TSTF) Standard TS change TSTF-425, "Relocate Surveillance Frequencies to Licensee Control-RITSTF [Risk-Informed TSTF] Initiative 5b," Revision 3 (ADAMS Accession No. ML090850642). The Federal Register notice published on July 6, 2009 (7 4 FR 31996), announced the availability of this TS improvement.
The NRC staff has determined that additional information is necessary to complete its review.
The request for additional information (RAI) is enclosed. A draft of these questions was previously sent to Mr. Paul Willoughby of your staff on March 6, 2014, with an opportunity to have a teleconference to ensure that the licensee understood the questions and their regulatory basis, as well as to verify that the information was not previously docketed. A conference call was held on March 6, 2014, and Mr. Willoughby agreed that NextEra would respond to the RAI by April 18, 2014. Please note that if you do not respond to the RAI by April 18, 2014, the NRC staff may reject your request for relief under the provisions of Title 10 of the Code of Federal Regulations, Section 2.108, "Denial of application for failure to supply information."
If you have questions, you can contact me at 301-415-3100 or by e-mail at John. Lamb@nrc.gov.

SEABROOK STATION, UNIT 1 DOCKET NO. 50-443 By letter dated May 28, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13155A002), as supplemented January 29, 2014 (ADAMS Accession No. ML14035A457), NextEra Energy Seabrook, LLC (NextEra) submitted license amendment request 13-03 for Seabrook Station, Unit 1 (Seabrook). The proposed change is to the Seabrook technical specifications (TSs). Specifically, the proposed amendment would modify the TS by relocating specific surveillance frequencies to a licensee-controlled program with implementation of Nuclear Energy Institute (NEI) 04-10, "Risk-Informed Technical Specification Initiative 5b, Risk-Informed Method for Control of Surveillance Frequencies."

The Federal Register notice published on July 6, 2009 (7 4 FR 31996), announced the availability of this TS improvement.
The NRC staff has determined that the following additional information is necessary to complete its review.
REQUEST FOR ADDITIONAL INFORMATION (RAI)
NEI 04-10 states, in part, that, "[p]lants implementing TSTF-425 shall evaluate their PRAs [probabilistic risk assessments] in accordance with [Regulatory Guide (RG) 1.200]."
NRC Regulatory Issue Summary 2007-06, "Regulatory Guide 1.200 lmplemention,"
states, in part, that, "[i]f an implementation period for routine, limited scope risk-informed license applications is needed, the NRC would expect licensees to fully address all scope elements consistent with Revision 2 of RG 1.200 by the end of 2009."
The response to RAI 3, dated January 29, 2014, indicated that the fire and seismic portions of the Seabrook PRA have not been assessed against the PRA Standard referenced in Regulatory Guide 1.200, Revision 2.
As such, please describe, in more detail, how fire and seismic events will be assessed in terms of NEI 04-10 guidance, such as qualitative or bounding risk analyses in Step 10.
