HTH process, rolled threads, and a larger radius on the undercut of the cap screw head. (Section 3.9.5) 72[O] Based on its review, the staff asked TVA several For NRC Inspection /
questions regarding the ICC instrumentation. Review TVA responded to the staff questions by letter dated October 26, 2010 (ADAMS Accession No. ML103020322). The NRC staff has not completed the review of the additional information provided by TVA. The staff will provide its evaluation after completion of that review. (Section 4.4.8) 73[P] The NRC staff will inspect to confirm that TVA For NRC Inspection /
has completed the WBN Unit 2 EOPs prior to fuel Review load. (Section 7.5.3) 74[Q] The NRC staff will verify installation of the For NRC Inspection /
acoustic-monitoring system for the power- Review operated relief valve (PORV) position indication in WBN Unit 2 before fuel load. (Section 7.8.1) 75[R] The NRC staff will verify that the test procedures For NRC Inspection /
and qualification testing for auxiliary feedwater Review initiation and control and flow indication are completed in WBN Unit 2 before fuel load.
(Section 7.8.2) 76[S] The NRC staff will verify that the derivative time For NRC Inspection /
constant is set to zero in WBN Unit 2 before fuel Review load. (Section 7.8.3) 77 It is unclear to the NRC staff which software V&V documents are applicable to the HRCAR monitors. TVA

(Section 7.5.2.3) 78 TVA intends to issue a revised calculation reflecting that the TID in the control room is less than 103 rads, which will be evaluated by the NRC staff. (Section 7.5.2.3) 79 TVA should perform a radiated susceptibility survey, after the installation of the hardware but prior to the RM-1000 being placed in service, to establish the need for exclusion distance for the HRCAR monitors while using handheld portable devices (e.g., walkie-talkie) in the control room, as documented in Attachment 23 to TVAs letter dated February 25, 2011, and item number 355 of TVAs letter dated April 15, 2011. (Section 7.5.2.3) 80 TVA should provide clarification to the staff on how TVA Standard Specification SS-E18-14.1 meets the guidance of RG 1.180, and should address any deviations from the guidance of the RG.

(Section 7.5.2.3) 82 The staff concluded that the information provided by TVA pertaining to the in-containment LPMS equipment qualification for vibration was incomplete. TVA should provide (item number 362 of ADAMS Accession No. ML111050009), documentation that demonstrates the LPMS in-containment equipment has been qualified to remain functional in its normal operating vibration environment, per RG 1.133, Revision 1. (Section 7.6.1) 83 TVA should confirm to the NRC staff the completion of the data storm test on the DCS. (Section 7.7.1.4) 84 TVA should provide additional information for the NRC staff to complete its review of post-LOCA long term cooling boric acid precipitation. (Section 15.3.1) 85 The 95/95 peak local oxidation was calculated to be 1.04 percent, while core-wide oxidation was calculated to be much less than 0.1 percent. TVA should provide to the
Page 21 of 23 SSER NRC SSER Item Item TVA Status No. Description Status NRC staff the value of the decay heat multiplier used for this limiting large break, in order for the staff to complete its evaluation. (Section 15.3.1) 86 TVA should demonstrate to the staff, in the WCOBRA/TRAC analysis of the limiting break, that the core remains covered with a two-phase mixture and can be cooled for an indefinite period of time. (Section 15.3.1) 87 In order for the staff to complete its evaluation, TVA should provide (1) a time step sensitivity study for the limiting break displaying downcomer boiling, (2) a list of ten key parameter plots for the worst case downcomer boiling transient, (3) values for the lateral k-factors used in the evaluation, and (4) the manner in which condensation was modeled in the downcomer. (Section 15.3.1) 88 It is also unclear to the staff that the entrainment correlation information has been incorporated into the EOP, to ensure that operators do not initiate hot and cold side injection during the period of time that entrainment could preclude injection into the hot legs. TVA should provide the EOP guidance/instructions for the operators to the staff for review. (Section 15.3.1) 89 TVA should demonstrate, quantitatively, the applicability of the generic analysis to WBN Unit 2, to demonstrate that the EOP instructions to the operators can effectively deal with the failure of a bottom mounted instrument tube in the lower head.
