Subject:

WATTS BAR NUCLEAR PLANT (WBN) - UNIT 2 - FINAL SAFETY ANALYSIS REPORT (FSAR), AMENDMENT 112

References:

1. TVA letter to NRC dated February 13, 2014, "Watts Bar Nuclear Plant (WBN) - Unit 2 - Final Safety Analysis Report (FSAR), Amendment 111'
2. TVA letter to NRC dated May 8, 2014, "Watts Bar Nuclear Plant (WBN)

Unit 2 - Inservice Test (IST) Program/Preservice Test (PST) Program" This letter transmits WBN Unit 2 FSAR Amendment 112 (Al 12), which reflects changes made since the issuance of Amendment 111 on February 13, 2014 (Reference 1). contains a summary listing of FSAR sections and corresponding Unit 2 change package numbers associated with the Al 12 FSAR changes.

FSAR Al 12 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. 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).

In regard to Supplemental Safety Evaluation Report (SSER), Appendix HH Open Items, the following can be stated to address three open items:

U.S. Nuclear Regulatory Commission Page 2 May 30, 2014 For Open Item No. 1, involving power assisted cable pulls, WBN Unit 2 construction has not made nor will not be making any such power assisted cable pulls in the completion of WBN Unit 2. Al 12 addresses Open Item No. 35, involving Component Cooling System (CCS), and Open Item No. 91, involving Feedwater Purity.

In addition, FSAR Change Package 2-112-10 addresses a clarification to the IST Program code of record as committed to in Reference 2. provides replacement disks for Amendment 111 provided in Reference 1.

During the course of Amendment 112 preparation, it was discovered that the discs containing the Amendment 111 files previously provided by Reference 1 did not contain Section 6.2,6.

Enclosures 5 and 6 have been updated to reflect this addition for file sizes related to the security-related and the publicly available OSMs for Amendment 111.

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

I declare under the penalty of perjury that the foregoing is true and correct. Executed on the 3 0 th day of May, 2014.
