SUPPLEMENTARY INFORMATION:

The NRC has granted the request of Tennessee Valley Authority (the licensee) to withdraw its October 2, 2013, application (ADAMS Accession No. ML13280A267) for proposed amendment to Facility Operating License Nos. DPR-77 and DPR-79 issued to the licensee for operation of the Sequoyah Nuclear Plant, Units 1 and 2, located in Hamilton County, Tennessee.

The licensee requested to revise Units 1 and 2 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.

This proposed amendment request was noticed in 78 FR 74184 dated December 10, 2013 and supplemented by letters dated December 11, 2013 (ML13354A715), August 18, 2014 (ML14231B294) and October 22, 2015 (ML15295A427).
