Tennessee Valley Authority , Post Office Box 2000 , Decatur , Alabama 35609-2000 November 30, 2016 ATTN: Document Control Desk U.S. Nuclear Regulatory Commission Washington, D.C. 20555-0001 Browns Ferry Nuclear Plant , Units 1, 2 , and 3 10 CFR 50.4 10 CFR 50 , Appendix E Renewed Facility Operating License Nos. DPR-33 , DPR-52 , and DPR-68 NRC Docket Nos. 50-259 , 50-260 , and 50-296

Subject:

Emergency Response Data System Changes The purpose of this letter is to provide changes to the Emergency Response Data System (EROS), as required by Title 10 of the Code of Federal Regulations (10 CFR) 50 , Appendix E , Section Vl.3 , "Maintaining Emergency Response Data System" for Browns Ferry Nuclear Plant (BFN), Units 1 , 2 , and 3. The Tennessee Valley Authority performed a review of the EROS Data Point Library to identify discrepancies between the EROS Data Point Library and the applicable technical instructions. Several EROS points were changed in the Data Point Library but were not changed in the applicable technical instructions.

Additionally , these changes were not submitted to the NRC in accordance with 10 CFR 50 , Appendix E , Section Vl.3.a , which requires a notification within 30 days after any software or hardware changes to any transmitted data points identified in the Data Point Library are made. The changes to the EROS Data Point Library include instrument range parameters , alarm/trip set points Modes of operation, how data is processed , unique system description Modes of operation and parameters , plant specific point description titles , and engineer i ng units. This deficiency has been entered into the Corrective Action Program. The changes to the EROS Data Point Library are summarized in the Enclosure. T here are no new regulatory commitments in this letter. Please direct questions concerning this issue to Jamie L. Paul at (256) 729-2636.
