(Section 13.3.2) REP Submit final Unit 1/2 REP to NRC
Due date: October 1, 2011 (38) pg 13-14 The NRC staff will confirm the availability and operability of the ERDS for Unit 2 prior to issuance of the Unit 2 OL. (Section
13.3.2.6) REP The Emergency Response Data System software has previously been modified and tested for the Watts Bar Unit 2 addition. This unit can be selected from the ERDS menu to send data to the
NRC at this time. In addition, the
software has been developed and tested to send data from the WBN PEDS to the CECC. However, the official list of points for Watts Bar Unit 2 has not been provided by Unit 2 Design Engineering and, until this has been completed and submitted to the Computer Engineering Group for addition to the ERDS software, official testing of the software for this unit
cannot be completed with the NRC in order to declare the WBN ERDS Unit 2 operational. This list is derived from the official Data Point List. Once developed, Unit 2 Licensing submits the data to the NRC. Once this list has been
received by the NRC, it would require one month to add the list to the NRC data systems, write the test, schedule the test with TVA/NRC, run the test, and TVA submit the results.

(43) pg 13-23 Section V of Appendix E to 10 CFR Part 50 requires TVA to submit its detailed implementing procedures for its emergency plan no less than 180 days before the scheduled issuance of an
operating license. Completion of this requirement will be confirmed by the NRC staff prior to the issuance of an operating license. (Section 13.3.2.18) REP Submit Unit 1/2 REP implementing procedures (EPIP-1 thru EPIP-17) to NRC Due date: October 1, 2011 (Detchemendy)
(47) pg 6-12 The NRC staff noted that TVA's changes to Section 6.2.6 in FSAR Amendment 97, regarding the implementation of Option B of Appendix J, were incomplete, because several statements remained regarding
performing water-sealed valve leakage tests "as specified in 10 CFR [Part] 50, Appendix J." With the adoption of Option B, the specified testing requirements are no longer applicable; Option A to Appendix J retains these
requirements. The NRC discussed this discrepancy with TVA in a telephone conference on September 28, 2010. TVA stated that it would remove the inaccurate reference to Appendix J for specific water
testing requirements in a future FSAR amendment. (Section 6.2.6) Lic Complete - A104 Update received (48) pg 6-15 The NRC staff should verify that its conclusions in the review of FSAR Section 15.4.1 do not affect the conclusions of the staff regarding the acceptability of Section 6.5.3. (Section
6.5.3) LIC Complete - No TVA action Licensing to address in next SSER update letter (49) letter in folder The NRC staff was unable to determine how TVA linked the training qualification
requirements of ANSI N45.2-1971 to TVA
Procedure TI-119. Therefore, the implementation of training and qualification for inspectors will be the subject of future NRC staff inspections.

Lic Develop FSAR change from 10/4/10 submittal - Question 12-13.
Due Date: 5/27/11 (Stockton) 58 draft The staff has insufficient information to conclude that TVA has taken appropriate actions to reduce radiation levels and
increase the capabilit y of operators to control and mitigate the consequences of an accident at WBN Unit 2, in accordance with the guidance of NUREG-0737, Item II.B.2, or can maintain occupational doses to plant operators within the requirements of GDC 19. Therefore, the staff cannot conclude that the plant shielding for WBN Unit 2 is
acceptable. (Section 12.7.1)
