Subject:

WATTS BAR NUCLEAR PLANT (WBN) - UNIT 2 - FINAL SAFETY ANALYSIS REPORT (FSAR), AMENDMENT 97

Reference:

TVA letter to the NRC dated December 14, 2009, 'Watts Bar Nuclear Plant (WBN) - Unit 2 - Final Safety Analysis Report Amendment 96" This letter transmits WBN Unit 2 FSAR Amendment 97 (A97), which reflects changes made since the issuance of Amendment 96 on December 14, 2009 (Reference). This Unit 2 amendment incorporates changes resulting from TVA's ongoing design/reverification effort in support of completing the WBN Unit 2 design basis.

Enclosure 1 contains a "Summary Listing" of the location and corresponding Unit 2 FSAR change package numbers associated with the A97 changes. This is a listing of FSAR sections in which TVA has completed its design/reverification review and determined that design-related activities are complete; the verbiage is consistent with the Unit 1 Updated FSAR (UFSAR), as appropriate; and the section is ready for NRC review. Please note that Safety Evaluation Report Section 2.4, "Hydrologic Engineering" which was scheduled to be submitted in this amendment, has been rescheduled for February 2010 to allow incorporation of the most recent probable maximum flood evaluation data.

FSAR A97 is contained on the enclosed Optical Storage Media (OSM #1) (Attachment 1).

The FSAR contains security-related information identified by the designation "Security-Related Information - Withhold Under 10 CFR 2.390." TVA hereby requests this information be withheld from public disclosure in accordance with the provisions of 10 CFR 2.390. A redacted version of the FSAR is contained on OSM #2 (Attachment 2), which is suitable for public disclosure. Enclosure 2 contains a listing of the FSAR pages that have been redacted. Enclosure 3 lists the files and file sizes on the security-related OSM (OSM #1),

and Enclosure 4 lists the files and file sizes on the publicly available OSM (OSM #2).

U.S. Nuclear Regulatory Commission Page 2 January 11, 2010 TVA (WBN Unit 1) is currently preparing Unit 1 UFSAR Amendment 8 (A8) and will submit A8 on or before April 21, 2010, in accordance with 10 CFR 50.71(e)(4). To support NRC's review of the WBN Unit 2 FSAR, TVA has incorporated the approved Unit 1 A8 changes into Unit 2 A97, as appropriate. This letter does not close any "Generic Communications" or contain any new commitments.

If you have any questions, please contact me at (423) 365-2351.

I declare under the penalty of perjury that the foregoing is true and correct. Executed on January 11, 2010.

Sincerely, Masoud jestani Watts a Unit 2 Vice President
