SUBJECT:

SEABROOK STATION, UNIT NO.1 - ACCEPTANCE LETTER REGARDING LICENSE AMENDMENT REQUEST 12-04, APPLICATION REGARDING COLD LEG IN..IECTION PERMISSIVE (TAC NO. MF1158)

Dear Mr. Walsh:

By letter dated March 13, 2013 (Agencywide Documents Access and Management System Accession No. ML13079A122), NextEra Energy Seabrook, LLC (NextEra) submitted license amendment request (LAR) 12-04 for Seabrook Station, Unit 1 (Seabrook). The proposed change is to the Seabrook Technical Specification (TS). The proposed amendment modifies the circuitry that initiates high-head safety injection by adding a new permissive, cold leg injection permissive (P-15). This permissive prevents opening of the high-head safety injection valves until the reactor coolant system pressure decreases to the P-15 set point.

The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff's acceptance review of this amendment request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

Consistent with Title 10 of the Code of Federal Regulations (10 CFR), Section 50.90, an amendment to the license (including the TSs) must fully describe the changes requested, and following as far as applicable, the form prescribed for original applications. Section 50.34 of 10 CFR addresses the content of technical information required. This section stipulates that the submittal address the design and operating characteristics, unusual or novel design features, and principal safety considerations.

The NRC staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendment in terms of regulatory requirements and the protection of public health and safety and the environment. If additional information is needed for the NRC staff to complete its technical review, you will be advised by separate correspondence.

K. Walsh -2 If you have any questions, please contact me at (301) 415-3100.
