Subject:

WATTS BAR NUCLEAR PLANT (WBN) - UNIT 2 - FINAL SAFETY ANALYSIS REPORT (FSAR), AMENDMENT 104

References:

1. TVA letter to NRC dated March 15, 2011, "Watts Bar Nuclear Plant (WBN)

- Unit 2 - Final Safety Analysis Report Amendment 103"

2. TVA letter to NRC dated April 6, 2011, "Watts Bar Nuclear Plant (WBN)

3. TVA letter to NRC dated May 20, 2011, "Watts Bar Nuclear Plant (WBN)

Unit 2 - Response to Final Safety Analysis Report (FSAR), Chapter 11 and Final Supplemental Environmental Impact Statement (FSEIS)

Request for Additional Information" This letter transmits WBN Unit 2 FSAR Amendment 104 (Al 04), which reflects changes made since the issuance of Amendment 103 on March 15, 2011 (Reference 1).

In Reference 2 (Enclosure 1, Item 36), TVA committed to update Table 3.2-2 "to note that TVA Class G and H piping within the SGB System exists downstream of the safety-related containment isolation valves." TVA later discovered that the same information intended to be placed into Table 3.2-2 was already provided in Table 3.2-2a. Therefore, this change to Table 3.2-2 is no longer needed and thus this letter closes the commitment in Reference 2.

Al 04 also includes changes to FSAR Chapter 11 previously proposed via Reference 3. contains a summary listing of FSAR sections and corresponding Unit 2 change package numbers associated with the A104 FSAR changes. Most of these changes were the result of resolutions to NRC Requests for Additional Information.

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. 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).

There are no new commitments made in this letter. This letter does not close any "Generic Communications." If you have any questions, please contact Bill Crouch at (423) 365-2004.
