The NRC staff forwarded requests for additional information (RAls) in October 29, 2007, November 26, 2007, December 14, 2007 and December 20, 2007 letters.

DNC responded to the RAls in letters dated November 19, 2007 (Serial No. 07-0751), December 17, 2007 (Serial No.

07-0799), January 10, 2008 (Serial Nos. 07-0834, 07-0834A, 07-0834C, and 07-0834F),

In a letter dated January 18, 2008 (Serial No. 07-0846) DNC provided a response to Question AADB-07 -0107. In this letter (Attachment 1, page 2) DNC stated that: "DNC is providing the input and output files for each respective radiological accident analysis using RADTRAD version 3.02."

DNC intended to provide this information as an attached electronic media with the letter. However, this information was not provided to the staff with the January 18, 2008 DNC letter.

In a conference call on February 26, 2008, both the NRC staff and DNC agreed that there is no longer a need to provide this information since it is deemed beneficial but not critical for the NRC review of the response to Question AADB-07-0107. Therefore, this information will not be provided to the NRC.

The information provided by this letter does not affect the conclusions of the significant hazards consideration discussion in the December 13, 2007 DNC letter (Serial No.

07-0450C).
