Sequoyah 1 and 2 UHS LAR (TS-SQN-13-01 and TS-SQN-13-02) Acceptance Review (TAC Nos. MF2852 and MF2853)

By letter dated October 2, 2013 (ADAMS Accession No. ML13280A267), Tennessee Valley Authority submitted a license amendment request (LAR) for Sequoyah Nuclear Plant, Units 1 and 2. The LAR would revise the Technical Specifications (TSs) 3.7.5, Ultimate Heat Sink, to place additional limitations on the maximum average Essential Raw Cooling Water (ERCW) System supply header water temperature during operation with one ERCW pump per loop and operation with one ERCW supply strainer per loop. In addition, the one-time limitations on Unit 1 ultimate heat sink (UHS) temperature and the associated license condition requirements used for the Unit 2 steam generator replacement project are proposed to be deleted. The proposed changes would place additional temperature limitations on the UHS TS Limiting Condition for Operation 3.7.5 with associated required actions, to support maintenance on plant component without requiring a dual unit shutdown. The purpose of this e-mail is to provide the results of the NRC staffs acceptance review of this LAR. 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.

The NRC staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the NRC staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed LAR in terms of regulatory requirements and the protection of public health and safety and the environment. Given the lesser scope and depth of the acceptance review as compared to the detailed technical review, there may be instances in which issues that impact the NRC staffs ability to complete the detailed technical review are identified despite completion of an adequate acceptance review. If additional information is needed, you will be advised by separate correspondence.

If you have any questions, please contact me.
