Tennessee Valley Authority, Post Office Box 2000, Spring City, Tennessee 37381-2000 September 17, 2008 10 CFR 50, Appendix E U. S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, D.C. 20555-0001 Gentlemen:

In the Matter of ) Docket No. 50-390 Tennessee Valley Authority )

WATTS BAR NUCLEAR PLANT (WBN) UNIT 1 - EMERGENCY RESPONSE DATA SYSTEM (ERDS) DATA POINT LIBRARY (DPL), REVISION 2 Enclosed is ERDS Data Point Library, Revision 2, provided pursuant to 10 CFR 50, Appendix E, Section Vl.3.a. TVA revised the DPL to update descriptive statements and explanatory notes, such as steam generator dimensions and water level at the top of the U-tubes. These descriptive changes became applicable following the steam generator replacement project during WBN's cycle 7 refueling outage, Fall 2006. The delay in this update has been documented in the WBN corrective action process.

The enclosure to this letter, Data Point Library, Revision 2, supersedes the Data Point Library, Revision 1 provided in TVA's letter dated May 14, 1999.

There are no regulatory commitments associated with this submittal. If you have any questions concerning this matter, please call me at (423) 365-1824.

Sincerely, M. K. Brandon Manager, Site Licensing and Industry Affairs Enclosure cc: See Page 2
