1. Letter from TVA to NRC, "Application to Revise Sequoyah Nuclear Plant Units 1 and 2 Updated Final Safety Analysis Report Regarding Changes to Hydrologic Analysis (SQN-TS-12-02)," dated August 10, 2012 (ML12226A561, ML12226A562, ML12226A563).

By letter dated August 10, 2012 (Reference 1}, Tennessee Valley Authority (TVA) submitted a license amendment request (LAR) to adopt a revised hydrologic analysis for the Sequoyah Nuclear Plant (SQN), Units 1 and 2, Updated Final Safety Analysis Report (UFSAR). The LAR included numerous proposed UFSAR figure updates. During review of the LAR, the Nuclear Regulatory Commission (NRC) identified an apparent incorrect duplicate figure. Upon further inspection by TVA staff, two additional incorrect figures were identified.

TVA provided three corrected figures to replace the incorrect figures by letter dated January 16, 2014 (Reference 2).

Subsequent reviews conducted as part of the TVA corrective action program identified an additional figure originally provided in Attachment 3 of Reference 1 that requires replacement.

Please replace Figure 2.4.3-7 (Sheet 2 of 17) with the enclosed figure labeled with the same number.

U.S. Nuclear Regulatory Commission Page 2 February 20, 2014 Consistent with the standards set forth in 10 CFR 50.92(c), TVA has determined that the additional information provided in this letter does not affect the no significant hazards considerations associated with the proposed amendment previously provided in the Reference letter. TVA has further determined that the proposed amendment still qualifies for a categorical exclusion from environmental review pursuant to the provisions of 10 CFR 51.22(c)(9). Additionally, in accordance with 10 CFR 50.91 (b)(1 ), TVA is sending a copy of this letter and enclosure to the Tennessee Department of Environment and Conservation.
