Subject:

WATTS BAR NUCLEAR PLANT (WBN) - UNIT 2 - FINAL SAFETY ANALYSIS REPORT (FSAR), AMENDMENT 95

1. TVA letter to the NRC dated August 27, 2009, "Watts Bar Nuclear Plant (WBN) - Unit 2 - Final Safety Analysis Report Amendment 94"

References:

2. NRC letter to TVA dated August 14, 2009, "Watts Bar Nuclear Plant Unit 2 -

Confirmation of Schedule for Submission of Information to Support Operating License Application Review" This letter transmits WBN Unit 2 FSAR Amendment 95 (A95), which reflects changes made since the issuance of Amendment 94 on August 27, 2009 (Reference 1). This Unit 2 amendment incorporates changes resulting from TVA's ongoing design/reverification effort in support of completing the WBN Unit 2 design basis. This letter also responds to NRC's letter dated August 14, 2009 (Reference 2), requesting TVA to verify the schedule for providing information amending the FSAR. Specifically, NRC requested TVA to verify the schedule dates for submitting amendments on specific Safety Evaluation Report (SER) sections listed in the enclosure to NRC's August 14 letter. Enclosure 1 contains TVA's updated schedule dates for submitting amendments for the FSAR sections listed in NRC's letter. SER Section 12.7.1, "Plant Shielding," that corresponds to FSAR Section 12.3 was scheduled to be incorporated into this amendment but was not completed due to outstanding calculation issues. This section has been rescheduled to January 2010. FSAR Section 12.3 was the only section listed in the NRC August 14 letter that was scheduled to be submitted with FSAR A95 that TVA did not complete the design/verification review. contains a "Summary Listing" of the location and corresponding Unit 2 FSAR change package numbers associated with the A95 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.

AD573 Printed on recycled paper

U.S. Nuclear Regulatory Commission Page 2 November 24,2009 FSAR A95 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 10CFR2.390.

TVA hereby requests this information be withheld from public disclosure in accordance with the provisions of 10CFR2.390. 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 4 lists the files and file sizes on the security-related OSM (OSM #1), and Enclosure 5 lists the files and file sizes on the publicly available 'OSM (OSM #2).

Additionally, at the request of NRC/NRR, TVA is planning to expedite submittal of FSAR A96 that provides the rest of Section 7.0 on or about December 15, 2009. WBN is currently developing Unit 1 UFSAR Amendment 8.. TVA plans to incorporate any impacts from this UFSAR Amendment into Unit 2 A97, scheduled for January 2010.

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 November 24, 2009.

Sincerely, Masoud Ba;J_
