U.S. Nuclear Regulatory Commission Page 2 August 2, 2012 requested a conference call to discuss what operator actions were added, deleted, or changed, including actions credited in the Updated Final Safety Analysis Report (UFSAR) accident analysis. In addition, TVA was requested to provide any changes, additions or deletions of procedures and training for these affected operator actions.
In a telephone call between TVA and NRC representatives on July 25, 2012, TVA representatives clarified that no operator actions were added, deleted, or changed in the accident analysis. TVA identified that the assumptions of the fuel handling accident were provided as part of the Reference 1 letter in Enclosure 2, which is the calculation utilized to determine the radiological consequences associated with a fuel handling accident. The assumptions are described on pages 11 through 13 of the calculation.
The assumptions do not include any operator actions and no deletions related to operator actions were made in the calculation. The NRC requested during the phone conversation that this supplemental information be provided. Subsequent to the phone conversation, the NRC issued a formal letter (Reference 3) on July 27, 2012, requesting the information described in the electronic mail and requesting the information be provided to the NRC within 13 days of the letter.
Accordingly, the following are the responses to the three questions provided in the electronic mail and NRC letter of references 2 and 3:
Question 1 response: No operator actions were added, deleted, or changed in the accident analysis.
Question 2 response: There are no associated procedure changes related to operator actions since no operator actions were added, deleted, or changed.
Question 3 response: There are no associated training changes related to operator actions since no operator actions were added, deleted, or changed.
No changes are necessary to the enclosure and attachments provided in the Reference 1 letter.
TVA has determined that the supplemental information provided by this letter does not affect the no significant hazards considerations associated with the proposed TS changes provided in the reference letter. The proposed TS changes still qualify 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 to the Tennessee State Department of Environment and Conservation.
There are no regulatory commitments associated with this submittal. Please address any questions regarding this request to Terry Cribbe at 423-751-3850.
U.S. Nuclear Regulatory Commission Page 3 August 2, 2012 I declare under penalty of perjury that the foregoing is true and correct. Executed on the 2nd day of August 2012.
