Explain the difference in the evacuation time provided for General Population Evacuation Time, Normal Conditions 0-10 Mile Area, in Tab G which indicates a maximum evacuation time, and the maximum ETE identified in Tab F, Item 4c, Auto Owning Population Evacuated, which shows a different value.
- 18.
Subject:
Reporting Format [Basis: 10 CFR 50 Appendix E (IV); Appendix 4 to NUREG-0654 Section IV.A]
Section IV, Methodology, Item F, states that outlying sector populations were evacuated separately.
- a. Identify the outlying sectors that were evacuated separately.
- b. Identify the population used in these separate calculations, and explain if this population was deducted from the remaining ETE analysis presented in Tab F, Distribution Times for EPZ Evacuation.
- 19.
Subject:
Methodology [Basis: 10 CFR 50 Appendix E (IV); Appendix 4 to NUREG-0654 Section IV.B]
Section V, Demand and Population Estimate, Item C, Special Population, states that a tabulation of the school enrollments in the 10-Mile EPZ is contained in the respective county implementing procedures. The school enrollments in the county procedures only identify public schools.
- a. Describe how private schools such as Fairview Christian Academy and Spring City Christian Academy are included in the ETE analysis.
- b. It appears that additional buses may be required to carry out the evacuation of the Meigs County Schools. Explain the agreements to obtain these resources.
- 20.
Subject:
Methodology [Basis: 10 CFR 50 Appendix E (IV); Appendix 4 to NUREG-0654 Section I.C]
Tab F, Distribution Times for EPZ Evacuation, discusses the 10-mile EPZ ETE for the auto-owning population. Given the assumed mobilization time and evacuation speed described in Section III, Assumptions, explain how analysis results in that estimated time.
- 21.
Subject:
Emergency Planning Zones and Sub-Areas [Basis: 10 CFR 50 Appendix E (IV);
Appendix 4 to NUREG-0654 Section II.D]
Section III, Assumptions, Item E, states a maximum preparation time that is reflected in all distribution curves. Tab G, Summary of Evacuation Time Analysis, identifies a different preparation time for the permanent population. Explain which preparation time value was used in the analysis.
- 22.

The following question relates to Appendix C of the TVA Nuclear (TVAN) REP.
- 23.
Subject:
On Shift Emergency Response Organization [10 CFR 50.47(b)(2); Evaluation Criterion II.B.5, Table B-1]
On March 4, 2009, you submitted a copy of Revision 88 of Appendix C to the TVAN REP. In reviewing Appendix C Figure 1-C, On-Shift Staffing, the staff observed that the figure had been revised from previous revisions to show an additional Unit Supervisor and an additional Reactor Operator, presumably to reflect the licensing of Unit 2. On December 3, 2009, TVA submitted Revision 89 of the TVAN REP and Revision 89 of Appendix C. Revision 89 of Figure 1-C does not show these additional positions. The staff notes that Table B-1 of NUREG-0654, including Footnote 1, provides that for each unaffected nuclear unit in operation, maintain at least one shift foreman, one control room operator, and one auxiliary operator except that units sharing a control room may share a shift foreman if all functions are covered. If it is your intent to propose the use of the staffing shown in Revision 89 Figure 1-C, provide a justification that shows that all functions required in Table B-1 are covered at the affected unit, while providing adequate staffing to maintain safe operations at the unaffected unit.
