Browns Ferry Nuclear Plant, Units 1, 2, and 3

The U.S. Nuclear Regulatory Commission (NRC) has granted the request of the Tennessee Valley Authority (TVA, the licensee) to withdraw its license amendment request (LAR) dated September 16, 2015, as supplemented by letters dated April 15, April 29, May 11, May 25, June 16, August 24, and September 15, 2016, for a proposed amendment to Renewed Facility Operating License (RFOL) Nos. DPR-33, DPR-52, and DPR- 68, for the Browns Ferry Nuclear Plant (BFN), Units 1, 2, and 3. The proposed amendment would have revised the BFN, Units 1 and 2 Technical Specifications (TSs) by adding a new specification governing the safety functions for the emergency core cooling system preferred pump logic, common accident signal logic, and the unit priority re-trip logic. In addition, the LAR relocated the BFN, Unit 3, requirements for common accident signal logic and unit priority re-trip logic to a new specification governing the safety functions for the common accident signal logic and the unit priority re-trip logic for consistency with the changes to the BFN, Units 1 and 2, TSs.
