This completes the response to this item.

3. NRC Request (SSER 24 Appendix HH Item Number 126)

To enable the NRC staff to evaluate and review the IITA environmental qualification, TVA should provide the summary report of the environmental qualification for the IITA.

(SSER 24, Section 7.7.1.9.5)

TVA Partial Response to NRC Request In TVA to NRC letter dated September 30, 2011 (Reference 1) TVA provided a response to this item. Subsequently, WEC submitted to TVA non-proprietary qualification report WBT-D-3566 NP-Enclosure, Summary of IITA Equipment Qualification Watts Bar 2, dated October 2011. The report provides the summary of seismic qualification testing of the IITA (incore and excore). Attachment 9 contains the qualification report.
