Pursuant to 10 CFR 50.90, TVA is submitting a request for a TS change (WBN-TS-09-05) to License NPF-90 for WBN Unit 1. During the development of TS Change TVA-WBN-TS-07-14, submitted to the NRC on October 26, 2007 (Reference 1), the number for a new TS section being added to Section 5.7, "Procedures, Programs, and Manuals," was transposed. The new section should have been numbered 5.7.2.20 but was listed as 5.2.7.20 in the submittal released to the NRC.

The minor error was carried forward in the Safety Evaluation for Amendment 70, which was approved on October 8, 2008 (Reference 2).

This administrative error affected pages 5.0-25 and 5.0-25a. Provided in Attachment 1 of the enclosure are the existing TS pages marked up to show the proposed change. of the Enclosure provides revised (clean) TS pages.

U.S. Nuclear Regulatory Commission Page 3 April 30, 2009 TVA has determined that this minor error correction does not impact the Regulatory Analysis, nor does it change the conclusion of the No Significant Hazards Consideration evaluation submitted in Reference 1. However, for this minor error correction, a brief No Significant Hazards Consideration evaluation is provided in the enclosure which has determined that there are no significant hazards considerations associated with the proposed change and that this change qualifies for a categorical exclusion from the environmental review pursuant to the provisions of 10 CFR 5.22(C)(9). Additionally, in accordance with 10 CFR 50.91(b)(1), TVA is sending a copy of this letter and attachments to the Tennessee State Department of Public Health.

TVA requests routine processing of this TS change by the NRC and that the implementation of the revised TS be within 30 days of NRC approval.

There are no regulatory commitments associated with this submittal. If you have any questions regarding this change, please contact Mike Brandon, Manager, Site Licensing and Industry Affairs, at (423) 365-1824.

I declare under the penalty of perjury that the foregoing is true and correct. Executed on the 30th day of April 2009.

Since ely, Mike Skaggs Site Vice President Watts Bar Nuclear Plant Enclosures cc (w/enclosures):

Enclosure Tennessee Valley Authority Watts Bar Nuclear Plant Unit 1 Docket Number 50-390, NPF-90 Technical Specification Change WBN-TS-09-05 Change to Correct Minor Error in Amendment 70 Significant Hazards Consideration TVA is requesting to amend Operating License NPF-90 for the WBN. The proposed change would correct a typographical error contained in Watts Bar Technical Specification 5.0, "Administrative Controls." During the development of TS Change TVA-WBN-TS-07-14, submitted to the NRC on October 26, 2007 (Reference 1), the number for a new TS section being added to Section 5.7, "Procedures, Programs, and Manuals," was transposed. The new section should have been numbered 5.7.2.20 but was listed as 5.2.7.20 in the submittal released to the NRC. The minor error was carried forward in the Safety Evaluation for Amendment 70, which was approved on October 8, 2008 (Reference 2). This administrative error affected pages 5.0-25 and 5.0-25a.

TVA has evaluated whether or not a significant hazards consideration is involved with the proposed amendment(s) by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of Amendment," as discussed below:

1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No.

This change is limited only to correcting a typographical error in a section number (5.7.2.20 versus 5.2.7.20) contained in Technical Specification Section 5.0, which will not change the intent of the added section previously approved in License Amendment 70. Therefore, no increase in the probability or consequences of an accident previously evaluated has been created.

2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No.

This change is limited only to correcting a typographical error in a section number (5.7.2.20 versus 5.2.7.20) contained in Technical Specification Section 5.0, which will not change the intent of the added section previously approved in License Amendment 70. Therefore, the possibility of a new or different kind of accident from those previously analyzed has not been created.

3. Does the proposed amendment involve a significant reduction in a margin of safety?

Response: No.

This change is limited only to correcting a typographical error in a section number (5.7.2.20 versus 5.2.7.20) contained in Technical Specification Section 5.0, which will not change the intent of the added section previously approved in License Amendment 70. Therefore, the proposed change does not involve a significant reduction in a margin of safety.

Conclusions Based on the above, TVA concludes that the proposed amendment presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified. In addition, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

ENVIRONMENTAL EVALUATION A review has determined that the proposed amendment would not change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would not change an inspection or surveillance requirement. In addition, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure.

Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.
